Towards an incremental development of discrete-event simulators for batch plants: Use of object-oriented concepts

Abstract This paper deals with the development of a general methodology for designing discrete-event simulators (DES) for batch plants, using object-oriented techniques. This approach was first applied to the design of a DES model for a semiconductor facility (MELISSA) and to the extension to a fine chemistry environment (AD-HOC). It is shown that the use of an object-oriented language led to a great reduction in the rewriting cost from MELISSA to AD-HOC.
