摘要:

研究了一类有并行联系的多台单机模型调度问题;考虑了机器工作中人员操作的因素,在人员数量及其作业速度差异的约束下,研究了如何合理安排员工工作和产品工序加工顺序;用遗传算法求解该问题,提出了基于员工和产品工序的混合编码方法,避免了遗传操作过程中不合理解的产生,并用MATLAB编程进行实例求解,得到了满意的结果,同时对比了不考虑人员因素的单机模型的情况,验证了研究的有效性。

Abstract:

A class of scheduling problem with paralleled multiple single machine model was studied.Taking into account the factors of personnel to operate the machine,in the number of operators and its operating speed difference constraints,how to arrange staff work and machine operation sequence was studied.
Genetic algorithm was used to solve this problem and gave a new hybrid coding method of genetic algorithm based on the staff and machine operation to avoid the production of illegitimate solution in the
genetic manipulation process.Programming by MATLAB an instance was solved,and  the  efficient results were obtained.Comparing with the single machine model without the consideration of manpower the efficiency of new system was confirmed.

Key words: multiple single machine model, manpower factor, manpower and machine operation scheduling, genetic algorithm(GA)
