对DES实行优化控制的一种方法

对一类离散事件系统(DES),本文分析了其影响加工效率的因素,提出了优化控制的指标,并根据局部优化与全局优化相结合的原则提出了一种次优控制的方法,计算复杂度的分析表明了它的可行性和有效性,计算机仿真结果表明优化的闭环DES有一个从动态到静态最终稳定的过程,但只有当生产过程进入程序化生产后总加工效率才能随生产的进行而不断提高.

A Method of Realizing Suboptimal Control to Des

To realize an optimal control of a class ofDES (Discrete-Event-System), this paper analyses' the causes that affect the operation efficiency, presents a target for optimal control, and,according to the combination of local optimal and global optimal control, suggests an effective suboptimal control method. This method is analysed and proved to be not complex. The computer simulations indicate that the closed-loop DES has a process from dynamic to steady state. However, only when the producing process' is programmable, the whole efficiency can be better as the process continues.
