A city emergency evacuation simulation system based on multi intelligent agent belongs to the complex system simulation in the technical field of computerized emulation and solves the problems of single function of emergency simulation systems of all kinds and lack of intelligence of code of conduct of emergency entity. The system comprise a database module, a communication module, a parameter configuration interface module, a data management module, an intelligent agent generation module, a program execution module, a simulation module, a commanding and decision-making module and an assessment module. The database module comprises a generalized database, a knowledge base and a model base; wherein, the generalized database comprises a dangerous source subdatabase, a resource subdatabase, a foundational geodata subdatabase. The system can establish an efficient intelligent model, describes the precise behavioral process of emergent intelligent agents of all kinds in the state of disasters and emergency from two levels of macroscopy and microcosmic, can custom-make a parameter and expanded intelligent model, has commonality and expansibility, and makes up the shortage and deficiencyof the city emergency evacuation simulation study in regionality and comparatively large ranges.
