摘要

The process of analyzing and designing contemporary information systems is a complex one. Models of proposed system designs can be extremely helpful in determining their behavior prior to the expenditure of manpower, dollars and time on unsatisfactorily performing systems. The goal of this research was to investigate simulation methodologies and language capabilities which could ease model synthesis and analysis efforts in support of system analysis and design. This research focused specifically on data base subsystems and on satisfaction of user performance requirements. An integral part of the research was the modeling of a complex information system architecture to test the appropriateness of the information processing system simulator design facility (IPSS) as a design tool. This document describes the investigative and modeling efforts and reports on the following conclusions: IPSS is a useful tool for modeling in a topdown, modular manner complex information system architectures, and the proposed new capabilities would significantly reduce modeling efforts.
