A test implementation of the core manufacturing simulation data specification
2007 Winter Simulation Conference, 2007
This paper describes an effort of testing the Core Manufacturing Simulation Data (CMSD) information model as a neutral data interface for a discrete event simulation model developed using Enterprise Dynamics. The implementation is based upon a model of a paint shop at a Volvo Car Corporation plant in Sweden. The model is built for a Swedish research project (FACTS), which focuses on the work procedure of developing new and modified production systems. FACTS has found standardized simulation data structures to be of high interest to achieve efficient data collection in conceptual stages of production development programs. For the CMSD-development team, implementations serve as an approach to validate the structures in CMSD and to gather requirements for future enhancements. CMSD was originally developed to support job shops, but the results of this implementation indicate a good possibility to extend CMSD to also support flow shops.
Supporting manufacturing with simulation
Proceedings of the 28th conference on Winter simulation - WSC '96, 1996
In this paper, we identify and discuss the features we believe are key to the successful use of simulation as a manufacturing support tool. The discussion begins with three sample projects drawn from the authors' industrial and consulting experiences. Using these projects as motivation, we discuss the ideal project lifecyclemodel design, development, and deployment. For mo del design, we emphasize the importance of a clear and consistent specification, articulated in a written document. This specification should identify project customers, goals, and deliverables. We next review a range of model development options, stressing the existence of many non-simulation alternatives. We also discuss methods for model verification and validation. Finally, we consider the difficulties of model deployment, including simulation output analysis, data maintenance, and model integration. We close with several suggestions on how best to present simulation results to a management audience.
Neutral information structure for manufacturing simulations: a neutral information model for simulat
Wsc, 2003
Small machine shops typically do not have the resources to develop custom simulations of their operations or data translators to import their data from other manufacturing software applications. This paper presents an overview of an information model currently under development at the National Institute of Standards and Technology (NIST) to address this problem. The model provides neutral data interfaces for integrating machine shop software applications with simulation. The information model provides mechanisms for describing data about organizations, calendars, work, resources, schedules, parts, process plans, and layouts within a machine shop environment. The model has been developed using the Unified Modeling Language (UML) and the Extensible Markup Language (XML).

Towards an improved tool to facilitate simulation modelling of complex manufacturing systems
The International Journal of Advanced Manufacturing Technology, 2009
Computer-based simulation is one of the most valuable aids for manufacturing systems design, yet its use remains limited. The main reason for this is that current manufacturing systems are extremely complex and the user-friendly capabilities provided even by the most advanced simulation tools are not sufficient to cope with such complexity. On this basis, the paper explores the development of an improved tool to ease and speed up simulation modelling of complex manufacturing systems. A simulation interface, created and currently used at a major automotive manufacturer, is considered and a rigorous assessment of the extent to which this interface can support the simulation modelling process is provided. The paper evaluates the viability to use the interface as a basis for a general purpose simulation modelling tool capable of coping with any complex manufacturing systems, analyses its potential values, and proposes developments that can support the uptake of simulation techniques within the manufacturing industry.
Information structure to support discrete event simulation in manufacturing systems
Proceedings of the 2003 International Conference on Machine Learning and Cybernetics (IEEE Cat. No.03EX693)
Discrete Event Simulation (DES) is ranked among the top three tools for management support. However, it lags in becoming the successful tool in the industry that many experts have predicted. In this paper, sixteen projects accomplished in the area of DES have been analyzed in order to find the reasons for this delay. Most important is the lack of reliable manufacturing data in companies. This is due to inadequate practices within the organization, thus forcing users to build simulation models with estimated data. The paper also answers other questions as to why DES is an underutilized decision tool. DES is an information-intensive tool for decision-making, but has weak support concerning working procedures within organizations. Continuous generation of manufacturing data at all levels has to be supported by the working procedure in order to increase the use of DES as an everyday tool. How to improve this situation also is discussed.
Interoperability for virtual manufacturing systems
International Journal of Internet Manufacturing and Services, 2013
As manufacturing systems are often costly to develop and operate, simulation technology has been demonstrated to be an effective tool for improving manufacturing system design and the efficiency of manufacturing operations and maintenance. However, effectively and efficiently using simulation remains an important issue in the manufacturing industry. One of the principal reasons is the difficulty in processing, organising, and making use of the production-related information about the manufacturing system to be simulated. The difficulty stemmed from no standard representation for such data, making the effort to input data such as product attributes, processing times, and material quantity requirements into simulations complex, time consuming, and error prone. The core manufacturing simulation data (CMSD) standards, SISO-STD-008-2010 and SISO-STD-008-01-2012, specifically address this data representation issue. CMSD enables the import/export of many different types of factory data into computer simulations and other manufacturing systems. This paper describes the motivation for creating CMSD, standardisation efforts for CMSD, and related research efforts. This paper also describes how CMSD could be used as an integration mechanism in a sustainable manufacturing test-bed being developed at the National Institute of Standards and Technology. The test-bed will be a virtual manufacturing environment to support the testing and validation of sustainability metrics, assessment methods, and tools for use in manufacturing.
An architecture for a generic data-driven machine shop simulator
Proceedings of the Winter Simulation Conference, 2002
Standard interfaces could help reduce the costs associated with simulation model construction and data exchange between simulation and other software applications-and thus make simulation technology more affordable and accessible to a wide range of potential industrial users. Currently, small machine shops do not typically use simulation technology because of various difficulties and obstacles associated with model development and data translation. This paper provides an overview of work currently underway at the National Institute of Standards and Technology (NIST) to develop a software architecture, standard data interfaces, and a prototype generic machine shop simulator that can be readily, reconfigured for use by a large number of small machine shops. It also reviews prior work in this area and describes future work.
