Original scientific paper A developed model of the first structural shape of the matrix of product function and its requests model have been shown in practice. It relates functions of the product and its requests model, and technical systems that solve them. Functions are described by parameters, determined by physical laws. The technical systems and functions are related among themselves through correlations that fill the field of the matrix. The correlations are determined through winning parameters. Winning parameters are determined from the set of parameters of each function that have the greatest importance and influence on a specific function. The model is implemented into a developed prototype computer system. The first structural shape of the product function matrix and its requests model for the stator of the electrical motor of the intake unit have been generated through the prototype computer system. By implementing the product function matrix and its requests model in the process of product conceptual design, it becomes possible for a designer to examine himself by comparing the possibilities of implementation of new ideas with previously built products.

As product life cycles become shorter and shorter, stakes are higher in terms of sales and profits, making it an imperative for companies to enhance existing product families as much as possible. In this paper, a methodology using the Design Structure Matrix flow, Value Analysis, and the Commonality versus Diversity Index is proposed to improve an existing family of products. These tools assess and improve commonality/diversity trade-off within the family, feature satisfaction through design, and definition of new modules/components and their interfaces. A case study based on a family of refrigerators is detailed in this paper to demonstrate the methodology.

Building industry as one of the greatest industries in Iran comprises a significant share of waste generation in the country. Since a large quantity of the generated construction waste is buried due to the lack of a recycling protocol, it leads to an undesired waste of resources and causes severe environmental issues. This paper provides a study on the problem of material loss/construction waste in the Iranian Building Industry regarding the impact of relevant shortcomings in the stages of design, construction and supervision as the main phases of construction process. This paper includes the case studies from Isfahan, Mazandaran, Qazvin and Zanjan provinces, with a focus on the most important elements underlying construction waste generation. It also presents the experts points of view on prefab and conventional construction methods considering construction waste generation through a questionnaire-based survey. In general, the results show that Iranian project managers, engineers, contractors and workers believe that from 40 to 100 percent of construction wastes can be reduced via application of prefab construction methods. The results indicate that prefabrication can be considered as a solution to waste reduction in the Iranian Building Industry, whereas there is a dominant conventional method application in the industry.

Educational software means the method under which completed computer programmes may be used in terms of teaching contents, as well as programmes assisting and directing individual learning phase. Educational software comprises different teaching programmes, intended to specific users. One kind of educational software is formed of intelligent tutorial systems, i.e. artificial intelligence softwares (UI). According to the definition of one of artificial intelligence hypothesis, the following may be stated: “The engines acting as being intelligent engines may be possible. It is obvious that the answer to the question if UI is possible to occur, depends on relevant definition.” According to very technical point of view, the question of intelligent engines is actually optimization problem of choice of the best software agent for given architecture. Having this in mind, reasoning field is very important for development of UI-based educational software. Research field includes various them...

The paper presents modeling and analysis of product design and product portfolio management (PD-PM) domains interaction using an integrated simulation-optimization model. To represent the interactions, the product design phase is modeled as a discrete-scenario static system. The goal of this work is to develop a decision support framework that relies on product design-product portfolio management integration in order to aid product design planning and design execution. We utilize dependency matrix approach to illustrate domain relation between the product design and product portfolio management domains, and to facilitate their integration. Hence, the process integration model utilizes iterative effects, and their attendant processing duration and costs, to pattern domain interaction. An industrial case study is used to illustrate the application and utility of the proposed approach.

Ambliopia is the most common preventable cause of the loss of vision in developed countries, affecting the 2-5% of the population. This may evolve due to an abnormal visual experience, during the phase of visual development. Strabismus is the principal cause of the development of ambliopia, being 30 – 50% of the cases. The early detection of visual alterations causing ambliopia is considered to be of primary importance as the treatment is only effective during infancy, when the visual system becomes mature. The Health Council of the Canary Island Government a few years ago developed a program for the detection of visual alterations in childhood, and has recently incorporated the introduction of the TNO test to the habitual examinations. This investigation precisely intends to value the efficiency of the TNO Test in the early detection of ambliopia and the comparison with other habitual tests that are carried out in Primary Care. During the study, an exhaustive revision and comparati...

2025, Engineering Management and Modular Design: A Path to Robust Manufacturing Processes

Manufacturing environments, characterized by dynamic changes and uncertainties, demand effective strategies to minimize disruptions. This study introduces an innovative approach that integrates engineering management principles with modular design to prioritize risk mitigation and enhance robustness in manufacturing processes. From a systems engineering perspective, all manufacturing activities are perceived as interconnected components within a unified system. Leveraging the Axiomatic Design (AD) theory and the Design Structure Matrix (DSM) method, the study modularizes manufacturing process architecture to effectively curb risk propagation and manage system complexity. This study identifies the most optimal design as a pivotal architectural configuration, significantly improving the structural robustness and stability of the System of Interest (SOI). Empirical evidence supports this design’s capability to reduce complexities, thereby enhancing robustness within the broader system architecture. Notably, the proposed approach results in a substantial reduction in complexity, with the most optimal design exhibiting an approximately 82.79 percent reduction in work volume compared to the original design. Our research underscores the critical relationship between manufacturing and engineering management. Effective collaboration between these domains optimizes resource allocation, decision-making processes, and overall organizational strategy, leading to improved production processes and increased efficiency. Importantly, the study demonstrates a significant enhancement in modularization, resulting in elevated overall robustness in manufacturing processes. This highlights the proactive involvement of engineering management in the design phase to address production challenges, ultimately optimizing system performance. Thus, this research contributes to both practical applications and academic discourse by offering a novel approach to enhancing the robustness in manufacturing processes. By integrating engineering management principles and modular design strategies, organizations can fortify their processes against disruptions and effectively adapt to evolving circumstances.

The understanding of engineering systems demands diverse knowledge. Managers must consider the social and technical, the observable and unobservable, the concrete and abstract, and the animate and inanimate to successfully describe and purposively shape the system. Therefore, the complexity of engineering systems requires hybrid approaches for constructing our knowledge of such systems. This research attempts to bridge what has frequently been described and experienced as an unspannable chasm between the methods of social science and engineering science.

The goal of this research is to develop an analytical framework for screening for real options "in" an engineering system. Real options is defined in the finance literature as the right, but not the obligation, to take an action (e.g. deferring, expanding, contracting, or abandoning) at a predetermined cost and for a predetermined time. These are called "real options" because they pertain to physical or tangible assets, such as equipment, rather than financial instruments. Real options improve a system's capability of undergoing classes of changes with relative ease. This property is often called "flexibility." Recently, the DoD has emphasized the need to develop flexible system in order to improve operational, technical, and programmatic effectiveness. The aim of this research is to apply real options thinking to weapon acquisitions in order to promote the ability of weapon system programs to deftly avoid downside consequences or exploit upside opportunities. The practice of real options in systems engineering is a nascent field of inquiry. One of the most significant challenges in applying real options to engineering systems is the problem of identifying the most efficacious points within the system to create options. In order to identify the points of interest, systems engineers require knowledge about the physical and non physical aspects of the system, insight into sources of change, and the ability to examine the dynamic behavior of the system. We propose a two-phase process to perform this analysis. The first phase is a system representation phase that seeks to create an end-to-end representation of engineering system that includes endogenous interactions across system views and interactions with a systems environment. The next phase is an analysis phase that models the evolution of the engineering system in order to identify the real options in the system. This paper presents the system representation phase and proposes a methodology for creating an endto-end representation of an engineering system. The methodology for representing an engineering system extends existing systems engineering and architecting methods in two dimensions. First, the framework couples traditional architecting views to represent traceability and endogenous interactions within an engineering system. Second, the framework includes views of the system not represented in traditional engineering frameworks that includes social

The scope and complexity of engineered systems are ever-increasing as burgeoning global markets, unprecedented technological capabilities, rising consumer expectations and ever-changing social requirements present difficult design challenges that often extend beyond the traditional engineering paradigm. These challenges require engineers and technical managers to treat the technological systems as a part of a larger whole. Existing system modeling frameworks are limited in scope for representing the information about engineering systems. This paper presents a conceptual framework and an improved modeling framework for engineering systems. Its value is that it allows engineers and managers an improved means to visually arrange information and structure discourse in a way that facilitates better systems engineering. It augments the existing literature by providing a clear and concise framework for an engineering system, and provides a methodology for engineers to tag and organize systems information in ways that allow for better collection, storage, processing, and analysis of systems engineering data.

This paper presents the results of a study on the neolithic landscape of the Sopot culture in the area of Đakovština in Eastern Slavonija. A vast network of settlements was uncovered using aerial archaeology, which was further confirmed and chronologically determined by magnetometry, excavations, and field surveys. The study focuses on the site Tomašanci-Dubrava, where a drone was used to acquire vertical photographs to capture a detailed orthophoto of the feature in a maturing crop. The captured data revealed the subsurface archaeological features that affect the rate of plant growth, as observed on detailed digital surface models. The implications of this observation are discussed in the paper, including its potential use on a larger level with ALS data or aerial photographs taken by the state geodesic service to create DSM models of wider areas.

Technical debt is a software concept that can also be applied to descriptive models that are the foundation of model-based systems engineering (MBSE) efforts. The accumulation of excessive debt can lead to the collapse of a modeling effort and a loss of confidence in the promise of MBSE and digital engineering.
This presentation will explore the use of validation-supported modeling style and federation practices to minimize modeling technical debt. It will also compare and contrast these practices with those suggested by Ryan Noguchi (Aerospace Corporation) in his 2024 presentations The Nature of Technical Debt in the Development of Descriptive Models in MBSE and Modeling Principles to Moderate the Growth of Technical Debt in Descriptive Models.

In 2023, Here There Be Dragons: An Initial Study of Undetected Errors in Unvalidated SysML Models presented initial results from applying SAIC’s Digital Engineering Validation Tool to a collection of student models. These models, created from 2016-2023 at the University of Detroit Mercy, were developed with a consistent, albeit evolving, modeling methodology. Models created before 2018 were not automatically validated; those created after 2018 were validated with a growing set of validation rules. This presentation will discuss the challenges associated with the full implementation of SAIC’s v2.6 validation rules in IncQueryValidator, the server-side application of the rules to the 601 models available on the University’s Teamwork Cloud, and an analysis of the results. It will also discuss the development of metrics that can be used by modelers and stakeholders to assess model quality and completeness and estimate the value of conducting periodic server-side model health analysis.

This paper aims to reveal the development of design rework effort estimation by an analogy based framework. Design rework is focused in the repetion effort due to the interactions among subsystems or components within a considered system. Factors influence on design reworks are synthesised to be drivers impact on probility of occurence and effort required to resolve design rework issues both of which are verifiied by three industrial case studies. An Analogy based estimation approach is applied to develop a design rework effort estimation framework. The framework is practiced on the water pump development project from an engine manufacturer. The ultimate goal of this development is to develop a framework to estimate for extra time and effort required in the product development projects in the early stage of product development planning.

Modeling the urban system for urban health and well-being with the aim of finding ways to optimize the well-being of urban dwellers is a complex task. Different modeling approaches that consider specific parts of the urban system, e.g., environmental stressors, urban society, and urban morphology, need to be integrated. The conceptual model of health-related urban well-being (UrbWellth) has been constructed to provide a structure for an integrated modeling framework. However, interfaces between the different modeling approaches were not sufficiently identified until now. The challenge to specify and operationalize these interfaces is met by using the Design Structure Matrix (DSM) concept, which is widely used in design engineering. It is used here to identify necessary interfaces within the urban system by determining the relevant interface variables and processes. The conceptual model for UrbWellth is used to construct a DSM. The results of a clustering of this UrbWellth-based DSM reveal that the structure of the conceptual model is indeed suitable to serve as a basis for an integrated model. Further, a Multi-Domain DSM (MDDSM), which is an extension of the DSM based on expert knowledge from individual modelers, identified the interface variables for the integrated model components as well as the processes for which different modeling approaches need to be coordinated. Moreover, the approach based on MDDSM identified processes that are not yet covered by the available modeling approaches.

Electric House is a complete power plant system that supplies the electrical distribution network to site. Installation this power plant system have used in the world wide especially in industrial, utilities, renewable energy, outdoor switchgear and moveable substation. As we can see, in offshore industries application, Electrical House can be installed in Floating Production and Storage Offloading (FPSO). Since, engineering work is procedural and repeatable, complexity process will repeat again and again. Thus, problem happens stemming when complex processes which involves interdependent (feedback and iteration) in designing and fabricating process that affect the schedule of the project. Project management tools such as CPM, PERT and Gantt widely used to scheduling application do not address complexity of the interdependency and feedback iteration. In this research discusses scheduling of FPSO E-House module Fabrication Model using Dependency Structure Matrix (DSM) method in order...

Developing usable and desirable products requires an understanding of how users build close relationships with objects and how these relationships can be controlled by developers. This paper discusses the importance of the concept of affordances as an instrument useful for understanding the relationships between technical functions and user tasks. The approach introduces a Function-Task Design Matrix to link technical functions with user tasks and to capture relevant affordance-level requirements throughout the product architecture generation. Functional and Operational Affordance levels are introduced to help determine the product attributes necessary to optimize the ease with which users can undertake technical functions. The paper uses functional language, focusing attention towards the use of the product, rather then merely its workings. The tools for describing affordances are described first, followed by a step-by-step description of how they can be used to improve decisions d...

Developing a robust, product platform architecture brings an important competitive advantage to a company. The major benefit is reduced design effort and time-to-market for future generations of the product. This paper describes a step-by-step method that aids companies in developing such a product platform architecture. Using the concept of specification "flows " within a product development project, the design for variety (DFV) method develops two indices to measure a product's architecture. The first index is the Generational Variety Index (GVI), a measure for the amount of redesign effort required for future designs of the product. The second index is the Coupling Index (CI), a measure of the coupling among the product components. The design team uses these two indices to develop a decoupled architecture that requires less design effort for follow-on products.

Any complex technological system can be decomposed into a number of subsystems and associated components, some of which are core to system function while others are only peripheral. The dynamics of how such "core-periphery" structures evolve and become embedded in a firm's innovation routines has been shown to be a major factor in predicting survival, especially in turbulent technology-based industries. To date however, there has been little empirical evidence on the propensity with which coreperiphery structures are observed in practice, the factors that explain differences in the design of such structures, or the manner in which these structures evolve over time. We address this gap by analyzing a large number of systems in the software industry. Our sample includes 1,286 software releases taken from 19 distinct applications. We find that 75-80% of systems possess a core-periphery structure. However, the number of components in the core varies widely, even for systems that perform the same function. These differences appear to be associated with different models of development-open, distributed organizations developing systems with smaller cores. We find that core components are often dispersed throughout a system, making their detection and management difficult for a system architect. And we show that systems evolve in different ways-in some, the core is stable, whereas in others, it grows in proportion to the system, challenging the ability of an architect to understand all possible component interactions. Our findings represent a first step in establishing some stylized facts about the structure of real world systems.

The paper proposes an extension of the Design Structure Matrix to support designers in a rough sustainability evaluation of an industrial device in the early stage of its development. The methodology of assessment is based on an Augmented DSM (A-DSM), where the original DSM layout has been modified to allow developers to record information about product lifecycle and to manage the interactions of product components among them, towards other systems and with the environment outside. After a description of the novel matrix layout, a method is formalized. The proposed methodology will show that product evaluation is achieved by means of a combination of partial results that can be calculated already in conceptual phase: a set of environmental indicators and a couple of sustainability performance values. In accordance with this approach, the method is conceived as sustainability control panel useful to evaluate early environmental performance.

Real options analysis has traditionally been applied to the valuation of capital investment decisions. More recently, real options have been applied to the valuation of flexibility in system design decisions. However, different applications of real options are often considered in isolation. This paper introduces an integrated real options framework that supports holistic decision making under uncertainty for enterprises. This is accomplished by first introducing a new characterization of a real option as a tuple consisting of a mechanism and type, which disambiguates among 1) patterns of mechanisms that enable flexibility and 2) the types of flexibility in an enterprise. A new classification of mechanisms and types of options based on "where" they are embedded within the enterprise architecture is then devised, in order to enable a more comprehensive consideration of real options opportunities. The enterprise architecture in this context is described in terms of eight enterprise views and their dependencies. Modeling of the enterprise dependencies using a coupled dependency structure matrix (C-DSM) may be leveraged to propagate the impact of uncertainties and identify feasible types and mechanisms of real options. Examples are presented from a mini air vehicle (MAV) project, where challenging decisions span technical and social dimensions.

El modelo de consumo tradicional se basa en una economía lineal donde la empresa genera un producto o servicio para que sea consumido por el usuario final. Pero se observa que el rol del usuario está evolucionando paulatinamente desde el perfil de consumidor hacia el de productor dando lugar al concepto de prosumers. En este sentido, los usuarios están cada vez más formados en materia de diseño, algo que los habilita a intervenir sobre los productos que adquieren. De esta manera se ve que el prosumer también puede desempeñar el papel de diseñador ya que con sus intervenciones termina diseñando objetos nuevos. Por eso desde la enseñanza, surge la necesidad de potenciar a estos nuevos usuarios y que el contenido no esté sólo dedicado a desarrollar diseñadores nóveles. Incluso, algunos estudios previos evidencian la capacidad del diseño actual para crear productos centrados en el prosumer como una buena forma de unir diseño, industria y usuario y así permitir la articulación de varios eslabones. La industria no puede dejar que el rol de prosumer pase desapercibido ya que a pesar de que su impacto económico aún sea bajo, es un actor que cada vez va a estar más presente en la sociedad. Por lo tanto, nos encontramos ante una situación de fomento de la docencia STEAM en la que el aprendizaje basado en proyectos, las herramientas de fabricación digital y las de diseño con software libre permiten a los jóvenes crear y diseñar para sí mismos según sus necesidades, deseos y requisitos. Un cambio social que evidencia la necesidad de incluir en el proceso de diseño a estos nuevos usuarios capaces de participar en la fabricación de objetos.

The identification of risk of potential loss of system functionality within the early stages in designing complex systems is of growing importance for risk sensitive industries. In order to enhance early design and analysis of complex system architectures using design structure matrices, this paper introduces a failure propagation index methodology for analyzing functional architecture concepts for extremely large complex systems. Unlike the classical hazard analysis techniques which become difficult to handle for extremely large complex systems, this work proposes a functional failure propagation indexing method that segments a large complex system and applies failure propagation modulating factors to estimate the criticality of the system’s elements. The propagation index quantifies the relative impact of a functional failure on the overall architecture. The feasibility of the method is demonstrated using a functional model of a multifunctional actuation system architecture concep...

Currently there exists a need to produce product variants in faster and faster pace due to turbulent markets. Modular product structures are regarded as suitable for this. However committing to the modular product family is normally considered as a commitment to a certain architecture, which is often seen inflexible when compared to one-off-product development. Dynamic Modularisation (Dymo) business and product development paradigm aims to maintain the agility of one-off-product development when producing modular product families [1,2]. Now Dymo is developing from a proposed paradigm to an industrial practice. At this stage there is now experiences available, what kind of challenges a company is about to face when it adapts the Dymo type way of working. In this paper we present the fundamental background behind Dymo and an example of the implementation of Dymo. We discuss challenges in implementation and propose possible solutions.

The sequence of tasks is vital to the development of any project. The order of tasks is influenced by the information flow among them. The dependency structure matrix (DSM) can be used to model information flow. However, the information used by the DSM, including task duration, time required for communication, and task overlap, can have uncertain values. The aim of this paper is to analyze the effect of uncertainty on the scheduling of tasks using the DSM. Monte Carlo Simulation is applied to represent uncertainty in time estimates for projects using DSM. Conventional project duration, normal project duration with communication times, and normal project duration containing natural overlapping were considered for project time estimations. Several distribution functions were used to represent the uncertainty. It is concluded that project duration has normal distribution behavior that is independent of the type of input parameter distribution functions; that mean values of the input parameters give a good estimation of mean project duration; that interval and inner interval arithmetic give overestimation and underestimation of project duration times respectively.

Determining the proper sequence of interrelated activities in the design of a complex product is an irrefutable challenge for project management. The presence of components with different levels of technology in a complex product can disrupt project planning and cause cost overruns or schedule delays. This article presents a multiobjective model for organizing interrelated activities by taking into account the impact of technological capability and financial aspect of the project with a periodic perspective. First, a multidomain matrix is devised based on design structure matrix and technology readiness level to demonstrate the impact of components technology maturity level. Second, a mathematical model is developed according to rework caused by information dependence (minimizing total feedback value), project financial aspect (minimizing the difference between the budget and project costs), and technology maturity level of components (minimizing technology risk). Finally, a possibilistic programming approach is applied to cope with the uncertainty of input data; in addition, to deal with multiple objective functions, an interactive fuzzy solution approach is implemented. To validate the model and solution approach, a numerical experiment and a case study are conducted. Testing results illustrate the importance of technology maturity level in sequencing activities and indicate that the model can be introduced as a management tool for the financial feasibility study of the project due to the balanced use of budget.

For the purpose of concurrent engineering, ease of fabrication, time to first oil and reduction of onsite special competencies, the topside of FPSO is divided into several modules. Modularization minimizes interaction between the modules by increasing interaction within the module. Interactions are interfaces which must be recognized, defined, designed, documented and tested. The term interface refers to any logical or physical relationship required to integrate the boundaries between systems, subsystems and their environment. Systems and subsystems can include hardware and software. Interface management (IM) is a process to manage interfaces efficiently. The intention is to define a process which makes IM cost-effective and efficient. The proposed process starts breaking down the total system into several subsystems or modules with minimal interaction between them. Following the system engineering V-diagram all interface requirements, their possible solution, and method of testing them are documented. The Design Structure Matrix (DSM) is used to identify an optimal number of modules as well as for the tracking interface progress during the design, fabrication and installation phases. Strategies needed to manage interfaces between various subsystems are discussed. The methodology is equally applicable to other industries that also face interface management of complex systems.

The Design Structure Matrix (DSM), also called dependency structures matrix has been used in different areas. DSM has advantages like simplicity and it can organize the flow of data. Therefore, an area that DSM brings some important benefits is in project management. This tool can identify the cycle that iteration occurs, it also can minimize some revisions that are unnecessary, which accelerates the deliveries. The objective of this paper is to do a bibliometric analysis that focuses on identifying the most co-cited papers about DSM literature (only journals) that is connected with project management. The result shows that DSM can be used with different approaches like traditional, hybrid or agile project management.

2024, Matrix-based Product Design and Change Management

Engineering change management is a significant activity in industry and the importance of change management is appraised. Different reports suggest that ECs use around one-third of the engineering design capacity [1-3]. Since the later a change or the impact of a change is detected, the more expensive it becomes to undertake. Resource-intensive/costly engineering changes and their subsequent change propagation should be avoided earlier. Besides, unmanaged response to changes can cause the product to drift from its optimal design state and to demonstrate progressively poor performance [4, 5]. Most probable way to prevent this anomaly is to propose methods and tools which can detect changes efficiently and analyze the impact of change propagation proactively. Traditionally, engineers detect changes and predict change propagation based on abundant product data and complex product relations scattered in different files, which is time-consuming and error-prone. Meanwhile, the product development time is continuously decreasing, which further increases the burden on the engineers. As described in Chap. 5, there are many researches about engineering change management. However, few methods combine the product change-related data with the CAD models, which can facilitate the design change process automation and improve the efficiency of the change management. Jorge et al. [6] propose an annotation-centered design method to enhance the product model reuse. However, it is mainly developed to represent component functions, and a small amount of product data is recorded in the CAD model. MBD (model-based definition) is a new way of managing engineering and business processes using CAD model as the complete source of information for design, production, distribution, technical documentation, services, and the entire product lifecycle [7], and can contribute to the efficient implementation of design change. In this chapter, product change-related data is recorded in the introduced DCMBD (design change-oriented model-based definition) model with a predefined data structure. Besides, with the

According to recent results, Reconfigurable Manufacturing Systems or RMSs are the most efficient for manufacturing companies to adapt to the current market. This market is characterized by a high competitive level and very frequent and sudden variations in customer demands. Developing an RMS is not an easy task and a lot of work has been done in both academic and industrial fields to give solutions to address this issue. We can, for example, apply different methods and techniques used in the design of complex systems to design an RMS, these methods should be studied, analyzed, modified and improved if necessary before to be applied. Modularity is one of these techniques. In this paper, we will discuss how modularity could be used to develop RMS, and we will propose a standard approach based on the Design Structure Matrix to design an RMS with a modular architecture.

Construction projects are ambitious in terms of the complexity in its components, structures, design requirements, information flows, stakeholder integration and technological integration particularly in green building projects. As a consequence, management of these projects becomes increasingly integrated; however, risk management has taken little account of these interdisciplinary and iterative trends. This leads to poor risk management outcomes, where traditional risk management practices that rely on allocating risks to specific individual entities are not able to accommodate the collaborative facets. Experienced practitioners were interviewed regarding their current practices and techniques towards managing interdependent design tasks that resulted in inseparable collective risks. Prospective utilization of Dependency Structure Matrices (DSM) and its analysis of identifying the existence of these collaborative Design Risks among the clusters of designs are proposed as a solutio...

When talking about building construction, the accomplishment of stated schedules is a constant problem; therefore, there is a constant developers’ claim about design delivery being late. The design process is informally managed, with inappropriate planning techniques and low utilization of Information Technology resources. Based on these justifications, the first author’s Master Research was developed, in order to study the design process planning and to come up with ways of improving its efficacy. The Design Structure Matrix (DSM) has been applied in the research like a System Analysis tool, because it provides a compact and clear representation of a complex system and a capture method for the interactions, interdependencies and interfaces between system elements, and also as a Design Management tool, because it provides a design representation that allows for feedback and cyclic task dependencies. This paper introduces the mains conclusions of this research: a diagnosis of the pro...
