摘要: 硫化工序作为轮胎生产中的关键环节,其调度计划制定好坏直接影响整个轮胎生产流程的效率。设计了一种基于硫化顺序—硫化数量的离散编码方式,并在此基础上提出改进的和声搜索算法(IHS)求解以最小完工时间、最小换模费用和最小机器空闲率为优化目标的硫化车间调度问题。算法根据记忆库取值概率和音调微调概率分别对轮胎硫化顺序和硫化数量进行离散过程操作,定义动态微调值对加工数量进行微调扰动。实验结果表明该算法比基本和声搜索算法和粒子群算法具有更高的收敛精度。

Abstract: As a key link in tire production process, the scheduling plan of vulcanization process directly affects the efficiency of the whole tire production process. A discrete encoding method based on vulcanization order - tire number is proposed. An improved harmony search algorithm (IHS) is developed for scheduling the vulcanization workshop with the target of simultaneously minimizing the makespan, die-changing cost and machine idle rate. Vulcanization sequence and tire number are respectively discretized according to the harmony memory considering probability and pitch adjusting probability. The dynamic fine-tuning value is defined to fine-tune the processing number. Finally, the experimental results show that the proposed algorithm has higher convergence precision than the basic harmony search algorithm and particle swarm optimization algorithm.

Key words: harmony search algorithm, vulcanization workshop, multi-objective, dynamic fine-tuning, switch time, die-changing cost
