Automatic simulation model design from a situation theory based manufacturing system description.

摘要

This research is focused on the design and development of methodologies to automate the design process of simulation modeling from a situation-theory based system description and a scenario driven model scenario definition. An effort is also made in this research to develop the conceptualization of the design process in order to understand the art of simulation modeling. Some concepts which are inconsistently used in simulation literature are clarified in a hope to rationalize the terminology and to enhance the communication of the ideas across the simulation community.;One of the major achievements of this work is the investigation of the reasoning involved in the design process of simulation modeling including (1) the reasoning about the design of an ontology to capture a prestructured system description, (2) the reasoning involved in the simulation performance measures selection, dynamic boundary setting, and levels of detail specification for designing a model scenario of the generic model, and (3) the reasoning involved in the design of a simulation model.;To demonstrate that the approach is viable, a prototype system called Knowledge Based Framework (hereafter referred to as KBF) has been designed and developed. KBF plays two roles. It serves as a
