GIBSS: A Model Specification Framework for Multi-Stage, Manufacturing System Design

Heterogeneous simulation models are used in the initial, multistage design of discrete parts manufacturing systems. Current research is directed toward the development of an object-oriented, model-base environ ment which will facilitate heterogeneous modeling. To this end, the GIBSS (General ized Interaction Based Simulation Specifica tion) frameworks have been developed. The GIBSS conceptual frameworks permits the modular specification of heterogeneous models through the logical assemblage of entity, interaction, and transition objects. The GIBSS logic framework defines the synchronous execution of objects which use various mixtures of continuous and discrete event simulation techniques and/or manage multiple attribute sets. This paper describes the GIBSS frameworks and provides a case study of their application.
