Applicability of DSDS Simulation Modeling System to ESD System Acquisition Problems

摘要

The primary objective of the Performance Modeling and Simulation Project is to acquire computer-communications system performance modeling tools for use during the conceptual phase of C3 system acquisitions. These tools will assist the Electronic Systems Division Program Offices (ESD POs) and supporting MITRE personnel in performing conceptual-phase system engineering activities and analyses. Four such modeling systems -- NASA's DSDS (Data Systems Dynamic Simulator), TRW's PERCAM (Performance and Cost Analysis Model), Hughes' DAS/DDPM (Design Analysis System/Distributed Data Processing Model), and Martin Marietta's ARES (Automated Requirements Engineering System) -- have been examined. This report presents the results of implementing five benchmark problems using the batch version of DSDS and discusses how DSDS might be made more useful to ESD/MITRE. The benchmark problems were developed to assist in the evaluation of modeling systems. DSDS's applicability to these problems is presented, followed by an overall evaluation of DSDS and a discussion of potential enhancements to the system.
