Performance evaluation of communication network in a CIM system: A simulation approach.
The aim of CIM networking is to provide a means for integration of information flow. Hence, the communication network facility in a CIM system becomes an important resource or facility to be considered while building CIM systems. CIM networking differs from conventional computer networks as it involves information exchange of both control data and less critical non-real time data and internetworking with intercommunication probabilities depending on specific manufacturing functions. The focus of this research is to model and analyze the performance of a communication network in a typical computer integrated manufacturing environment. As the proper operation and functioning of a CIM system depends on its communication network also, care has to be taken not to overload the system. At the same time providing overcapacity means high unnecessary costs. So, it is important before adding new machines or facilities to the network to determine whether the network can accommodate new communication load. SLAM II (Simulation Language for Alternative Modeling) is used for modeling because of its capabilities of process and discrete event simulation modeling. The model was found to be sensitive and followed logical expectations and was verified correct. Complete validation was not possible because of the non-availability of data from a real system to compare with. (Abstract shortened by UMI.)Dept. of Industrial and Manufacturing Systems Engineering.
