Szukana fraza: [Abstract = "The paper addresses issues associated with the application of parallel discrete event simulation \(PDES\). We discuss the PDES terminology and methodology. Particular attention is paid to the software environment CSA\&S\/PV \(Complex Systems Analysis \& Simulation \- Parallel Version\), which provides a framework for simulation experiments performed on parallel computers. CSA\&S\/PV was applied to investigate several real\-life problems. The case studies are presented for both computer and water networks."]
