An Optimal Allocation Model for Smart Production System in Limited-Cycle Problem with Multiple Periods Considering Quality and Due Time ~the Case of Different Worker Levels~

In recent years, corporate quality irregularities have been reported in various media outlets, shaking the confidence of companies and affecting sales and stock prices. This is true even in Japan's leading manufacturing industries. In addition, the increase in the number of foreign workers and differences in length of service have resulted in differences in workers’ abilities. Therefore, the objective is to find the optimal worker allocation rules that take into account quality and worker level in order to achieve efficient production. In this paper, we propose an optimal allocation model for smart production line in limited-cycle problem with multiple periods considering quality and due time. We also discuss the optimal arrangement strategy and characteristics in the case of different worker levels by numerical experiments.
