Performance Evaluation of Railway Computer Interlocking System Based on Queuing Theory

摘要

Micro-computer system is a large scale computer controlling system with the high demanding of real-time performance. There were some papers to discuss its safety and its structure [1][2][7]but very few papers to discuss the evaluation of its real-time performance and its dispatch method. In this paper we present two models based on the theory of random service to analyze the real-time performance of computer interlocking system.From analysis and comparison of the two models, we proposed the method to evaluate the real-time performance of computer interlocking system and a better dispatch principle to design the software. The models were tested in forms software and got the satisfied result in practice.
