Optimization and lifecycle engineering for design and manufacture of recycled aluminium parts (original) (raw)

Design: A Review Product design is one of the most important sectors influencing global sustainability, as almost all the products consumed by people are outputs of the product development process. In particular, early design decisions can have a very significant impact on sustainability. These decisions not only relate to material and manufacturing choices but have a far-reaching effect on the product’s entire life cycle, including transportation, distribution, and end-of-life logistics. However, key challenges have to be overcome to enable eco-design methods to be applicable in early design stages. Lack of information models, semantic interoperability, methods to influence eco-design thinking in early stages, measurement science and uncertainty models in eco-decisions, and ability to balance business decisions and eco-design methodology are serious impediments to realizing sustainable products and services. Therefore, integrating downstream life cycle data into eco-design tools is...

A MAS to Assist mechanical engineers in the product’s design process

Designing and industrializing a new mechanical product in extended enterprise requires collaboration between engineers of each one and with different specialties. Each of these engineers use different software tools such as project management software, calculus software, CAO, etc., which leads to the creation of heterogeneous knowledge. The management of knowledge begins with its identification. The aim of this paper is to provide assistance for mechanical engineers to identify knowledge by creating domain ontologies. This assistance is led by a multi-agent system (MAS) called OCEAN (Ontology Creator, Extractor & Knowledge Annotator) that allows the creation of such ontologies.

Qualification and Certification of Life Cycle Engineering Skills of Design Engineers

2009

This paper proposes a skill set of Integrated Design Engineers based on the results of collaborative research and collaborations with industrialists. Key "integrated skills" include Product Lifecycle Engineering, Innovationdriven Design, Sustainable Design, Responsible Design, Networked Collaboration, Intercultural Skills, Requirements and Knowledge Engineering. We show how the established platform and certification rules of the ECQA can be used to leverage these assets to a worldwide unique qualification and certification platform for Integrated Design with a focus on Lifecycle Engineering.

Integration of Life-Cycle Constraints in Design Activity

From Knowledge Intensive CAD to Knowledge Intensive Engineering, 2002

The constraints concerning the whole life-cycle of a product must be integrated as soon as possible during the product design process, in order to decrease the final cost and to reduce the time to market. For this purpose, we propose a multi-actors and multi-views Cooperative Design Modeler, named CoDeMo, that allows the integration of different partners during the design activity. Our design methodology proposes the emerging of a product model from the specific constraints, results of the activity of the technologists, the manufacturers or the recycling actors. CoDeMo facilitates the dialogue between the diverse professions with the specification of the links existing among the views and by proposing a coordination system.

Multidisciplinary Design and Modern Manufacturing as Driving Forces for Industrial Engineers of a Future

Extended abstract: Nowadays, product design and manufacturing is no longer being done solely at one location. Moreover, engineering teams form based on a given task, a project or current necessity. All of these are making modern industrial organization changeable and adaptable as never before. Information era and development of new computer technologies has changed the ways that work is done today in so many different aspects. Modern industrial engineer can work with people, who might be on different countries, and even different continents, collaborate with engineers with different backgrounds. In this global and multidisciplinary environment, there is a need for a new skillet, many of which are not hard engineering, number crunching kind of activities. Moreover, they are related to so called soft skills which are related to interpersonal, time management and adaptability to change and function in ever changing, fast passed business environment. Globalization has set a new stage for engineering operations around the world. Hence, industrial engineers are managing and planning operations which are interconnected to operations and manufacturing of goods and services which are not necessarily at the same location or the same company. Companies from developed countries are focusing on research and development while repositioning their manufacturing operations outside their borders.

A multidisciplinary design tool with downstream processes embedded for conceptual design and evaluation

Proceedings of Proceedings of 15th International Conference on Engineering Design: ICED, 2005

The actual product ownership often remains with the manufacturer as functional (total care) products emerge in aerospace business agreements. The business risk is then transferred to the manufacturer why downstream knowledge needs to be available in the concept phase to consider all product life cycle aspects. The aim of this work is to study how a multidisciplinary design tool can be used to embed downstream processes for conceptual design and evaluation allowing simulation of life cycle properties. A knowledge enabled ...

Life Cycle Engineering for Materials and Technology Selection: Two Models, One Approach

Procedia CIRP, 2014

Under the umbrella of Life Cycle Engineering several engineering branches provide different approaches for industrial sustainable development and/or for modeling engineering analysis for decision-support on products design and materials/technology selection. The differences are mainly on the dimensions of analysis, i.e., environmental, economic, technical and/or social and on the scope of the analysis, namely cradle to grave or cradle to cradle. In this paper we discuss several approaches developed by the authors, providing a roadmap to guide designers to choose the most suitable for a specific problem. Case studies are presented to illustrate several types of applications and possible outputs of life cycle analyses.
