Computer simulation modeling is currently the most flexible method of manufacturing system analysis. Unfortunately, current simulation frameworks do not support the modular specification of homogeneous and heterogeneuos models.

A Simulation Program Generator (SPG) for prototyping heterogeneuos simulation models is developed. Objects in the model represent elements within a flexible assembly system. These elements are the robot, the conveyor, the part, the schedule plan and the robot program. These objects were modeled using the GIBSS simulation framework.

A model base and an user interface is developed to allow the construction and execution of simulation models. Instances of the objects are created and stored into the model base. These are retrieved later to construct a model The user interface is provided with an extensive set of tools for model creation and execution. Icons. representing objects, are selected and placed on the terminal screen and then connected together by interaction lines to create the complete model. The attributes of the objects can be altered and viewed on their respective panes.

The SPG is a step forward in the development of computer-aided manufacturing system design environments for prototyping heterogeneous models. It allows the rapid generation and execution of simulation models.
