DESP-C++: a discrete-event simulation package for C++

Abstract

DESP-C++ is a C++ discrete-event random simulation engine that has been designed to be fast, very easy to use and expand, and to be valid. DESP-C++ is based on the resource view. Its complete architecture is presented in detail, as well as a short 'user manual'. The validity of DESP-C++ is demonstrated by the simulation of three significant models. In each case, the simulation results obtained with DESP-C++ match those obtained with a validated simulation software: QNAP2. The versatility of DESP-C++ is also illustrated this way, since the modelled systems are very different from each other: a simple production system, the dining philosophers' classical deadlock problem, and a complex object-oriented database management system.
