摘　　要：为尽量降低单位时间内的平均生产费用,提出一种采用安全点策略对树形结构制造系统进行生产控制的方法。确定采用安全点策略制造系统的控制策略和优化目标,并给出利用仿真算法计算系统费用函数的方法;设定缓冲区特征量,在对系统进行分析的基础上提出一种安全点优化算法,该算法不断检测各缓冲区特征量,并以特征量为依据对安全点进行调整,从而实现安全点的快速优化;通过仿真试验将该方法与遗传算法进行了比较,仿真结果显示,提出的方法比遗传算法具有更好的优化性能。In order to minimize the production cost, an optimal hedging point policy method of production control in tree-structured manufacturing system is presented. Control strategy and optimization objective of the manufacturing system is determined, and simulation algorithm for calculating system cost function is proposed. Characteristic variable of buffer is set, and an optimal hedging point algorithm is proposed on the basis of system analysis. The algorithm continuously detects the characteristic variable of each buffer, and the hedging point is adjusted on the basis of the characteristic variable, thereby realizing fast optimization of the hedging point. This method is compared to the genetic algorithm through simulation experiments, which demonstrate that it has better optimization performance than the genetic algorithm.
