进行计算机仿真离不开时间递进机制。但传统的离散事件仿真时间递进机制却各有其不完美之处。本文分析了二种传统的离散事件仿真时间递进机制的缺陷, 并在此基础上提出了一种新的时间递进机制──混合时间递进机制。混合时间时间递进机制克服了传统时间递进机制的缺点, 效率高, 具有很强的灵活和适应性。能在精度和效率这对矛盾之间取得合理的平衡。

In the process of conputer simulation there must be a time advance mechanism,But the traditional tine advance mechanisms are not good enough to get both satisfactory accuracy and efficiency.in this paper the shotcomings of the tuaditional TAM(time advance mechanism)were discussed and a new TAM was proposed, The new TAM(Mixed time advance mechanism)is more efficient,more flexible and more suitable to simulaton of different kinds of system. The new TAM can easily get a blance between the simulation accuracy and simulation efficiency.
