Abstract
In the shop of manufacturing industry, demands of market fluctuates heavily.So we must adjust distribution of workers according to the work load every month.So we must fill up a lack of manpower by overtime works and holiday attendance. This problem is usually formulated as a multi objective integer programming. But, generally speaking, this formulation is intractable to solve the problem in the sense that its solution procedure becomes complex and comparing suboptimal solutions with optimal solutins are difficult. In turn this paper makes up the model based on the membership function of corresponding to the distribution ratio between regular workers and parttime workers, proposes a solutin procedure, and clarifies its efficiency.
