| 摘 要： | 在材料科学中,复杂动态规划方法是为在不确定条件下寻找结构复杂的非稳定动态目标的轨迹并进行最佳控制而发展起来的,为此,采用未知(不确定)的数学模型,演化规划成为动态规划及综合的非稳态目标的统一,这种先进的综合方法已成功用于解决铸模中合金熔体结晶时电流处理的最佳参数获得问题。

| Abstract: | The complex method of dynamic programming is developed in the conditions of uncertainty allowing to search for optimal the control trajectories of nonstationary dynamic objects of a complex structure specified for tasks in material science.For this purpose,by the use of an unknown mathematical model,a procedure of evolution planning is unified with a method of dynamic programming and complex nonstationary objects.The developed complex method is applied to solve the problem of finding optimal parameters involved in the current treatments upon the crystallization of alloyed iron melts in the casting mold. |
