A GPSS model of a complex on-line computer system

摘要

This paper describes the development of a GPSS model of the First National Bank of Boston's Real Time System (RTS). RTS is a generalized on-line teleprocessing, data base management, and work scheduling system which provides an interface between the IBM operating system (OS/MFT) and on-line COBOL applications programs. The architecture of the model, based on a hierarchical process string structure, is described along with specific techniques of implementation. Methods used to establish parameters and aspects of interpretation of the model which may be useful to others dealing with similar problems are discussed. A listing of the model is included as an appendix.
