A CLASS LIBRARY FOR DISCRETE-EVENT SIMULATION IN C++

A process-oriented simulation library has been developed in the object-oriented programming language C++. This language is very suitable for development of large simulation models and experimentation with simulation facilities. Features of the library include compile time type checking for absolute and relative time variables, a very flexible mechanism for generating event traces, and a general interrupt facility for simple communication between processes. The library is more expressive than Simula or the C++ coroutine library, and is approximately as sophisticated as DEMOS. The processes in the library are based on a general coroutine class, and the implementation of this class, which is hardware dependent, is discussed. A number of examples using the library are presented, partly based on use of this library in a major simulation project in a military command and control context. The library is is easily extensible because of the flexibility of C++ and the modular design of the library itself.
