A Study on the Generation of Simulation Codes for Process Design under CIM Environments

This study deals with an autonomous generation of simulation codes for the design of processes of a CIM system based on the concept of model transformation. We assume we have a functional model of an organization which is developed using the well-known IDEF0 methodology. Then, a modeling methodology, called PROWD(PRocess flOW Description), is suggested to develop the flow processes of the organization. To derive simulation specifications for the transformed PROWD model, we define a module of a “unit system” for each activity of PROWD model. Then specifications for system entities and resources are derived from input/ control/ mechanism/ output and entity flows of PROWD model. Entitiy queues are defined from the states and events of unit systems. Finally, SIMAN model frame is generated from those specifications through a suggested algorithm. The implementability and validity of the proposed approach is tested by developing a prototype of a computer-assisted design system on the operation processes of FMS installed at SNU-ASRI (Seoul National University-Automation and Systems Research Institute).
