Abstract: The paper gives up some hypothesis of the job shop scheduling problem.Firstly,the working procedure is planed following the priority of the tasks.Secondly,one working procedure of the task can be done by the combination of workpieces not only by one workpiece.Finally,a model based on the graph theory is introduced,an algorithm based on the ant colony algorithm is proposed and a case study is used to illustrate the feasibility and effectiveness of the proposed method.

Key words: job shop scheduling, combination of workpieces, graph theory

摘要: 放宽了对于生产调度问题的一些假设,首先根据任务的优先级安排生产,其次令一批工件的某道工序可以由多台设备组合加工;利用图论理论,建立了基于设备组合的数学模型;基于蚁群算法的思想,给出了求解方法。最后通过实例进行了验证。
