It introduces a new C++ simulation package based on the resource view, with detailed architecture, user manual, and validation against established software.

Findings

Simulation results match validated software QNAP2

Successfully modeled diverse systems including production, deadlock, and database

Demonstrated versatility and validity of DESP-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 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 philosopher classical deadlock problem, and a complex object-oriented database management system.
