Multi-agent Delay Simulation Model in Mass Rail Transit System

A primary delay is the deviation from a scheduled process time caused by disruption within the process. Delay is controlled by timetable and shows the characters of random occurrence. Rail transit system is a complex system which is dynamic, nonlinear, self-adaptive, random-occurrence and schedule-controllability. The multi-agent method enlarges the range of computer applying in rail system. This paper brings forward the delay simulation model which bases on multi-agent, and discusses the definition, characters, applying of multi-agent. Emphasizes the frame of delay simulation system basing on multi-agent, and builds a multi-agent delay simulation model which bases upon the train agent-gather, adjusted strategy agent-gather, and simulation environment. By the end, the model was illustrated by a sample of rail transit line 3 and line 4 in Shanghai.
