最优策略

In the heredity community renewal process, the paper uses one kind of new crossover operator——Improvement Order Crossover, the better solution two difficult problems both has been able to maintain the fine characteristic of father generation, does not destroy the sub-way which produces already in the most superior routing, and can guarantee when participation in the crossover two individual body is same, causes the genetic algorithms not to be able precociously to restrain in the partial optimal solution.

在应用遗传算法求解时，提出采用惩罚策略处理目标函数中对车辆容量的限制和客户对不同时间窗的需求约束，从而使目标解所对应的染色体能够根据违反约束的程度，具有不同大小的适应度；在遗传群体更新过程中，本文采用一种新型的交叉算子——改进的顺序交叉，更好的解决了既不破坏父代染色体中已产生的最优子路径，还能保证当参与交叉的两个个体相同时，遗传算法不会早熟收敛于局部最优解的两个难题。

The flexible manufacturing systems considered in the paper consist of possible unreliable workstations, whose inputs may be random. We derive the optimal input and service feedback control policy by using the uniformization technique and stochastic dynamic programming. It is shown that the optimal policy is of bang-bang type. Numeric example is given to illustrate the results.
