A study on object-oriented model repository for manufacturing system modeling

Abstract

The objective of the present research is to develop a formal modeling method, aimed at realising concurrent development and integration of various manufacturing system models. An object-oriented model repository of the manufacturing system is discussed to establish a systematic and logical criteria for classifying the manufacturing system models from various viewpoints. Contents and structures of manufacturing system models are discussed from the viewpoint of the concurrent and hierarchical production planning problems, and model components and their relations to be stored in the model repository are proposed. A prototype of a model repository is developed and applied to the production planning problems.
