A simulation of a minicomputer-based data base transaction system

This paper is a presentation of a model which simulates an on-line minicomputer-based information system dealing with the installation and maintenance of private line circuits. The model was designed and implemented subject to several user objectives. An important objective is to identify serious bottlenecks early in system development. If such bottlenecks are identified early, the cost involved in relieving the congestion could be minimized. Moreover the model is used to study the effects of parameter and design changes on system performance and to evaluate the viability of the system.
