FMS生产调度的参数优化

基于离散事件动态系统的线性系统理论，本文研究了ＦＭＳ的最大机床利用率问题。只靠作业排序和托盘优化不能有效地改善各机床的负荷平衡，选择适当的工件输入比例，可以使各机床都达到最佳利用率，这不仅是一个静态负荷平衡的问题，它还影响系统的动态运行过程和工作周期。本文分析了各种因素对机床利用率的影响，将工件输入比例优化归结为一个整数规划问题，并给出了算法和例题。     

A kind of Expert Control Combined with the Supervisory Theory for Discrete Event Dynamic Systems

To overcome the shortages of the supervisory theory for Discrete Event Dynamic Systems,a kind of expert control combined with the supervisory theory is proposed,also a practical example is given to illustrate its effectiveness.     

Dynamical Programming Algorithm for Multilayer feedforward Neural Networks

This paper trains the multilayer neural networks using dynamical programming.The weithts are adjusted layer by layer. The optimal weishts of each layer are calculated using OBPalgorithm proposed in the related reference. The globally optimal weights of each layer can be obtained by finite iterations.     

A Minimax Theorem about Saddle Functional

A minimax theorem is proved by taking advantage of Ekeland's variationalprinciple and the P. S. condition. This theorem can be regarded as an improvement of the theoremdue to Manasevich.
