In this study, we grasped the actual business in the print process which a part supplier has. And we proposed a heuristic solution method for the production planning problem. To begin with, by the business realities grasping on an actual factory, we proposed a new know-how. So far, the workers depended on his experience and intuition when they worked in the print process. To this, we proposed a clear rule as the selection rule of the lot sizing. Moreover we applied the proposal method to the concrete problem, its effectiveness is confirmed. In simulation, we used the data that the print process had actually done. From comparison with the results of obtaining by the simulation and the actual production, we were able to show the effectiveness of our logic. Besides, we are paying attention to the manufacturing process of the semiconductor. The manufacturing process of the semiconductor is similar to the print process. An effective cancellation of the competition is thought by manufacturing it bringing many lots together in the same process. Here, against the print process which processes the products as one by one with one machine, the semiconductor manufacturing has to use the many equipments many times repeatedly, the lots of various progress exists together in the same process. Therefore, many factors such as the repetition arrival time, machines and etc. relate for the optimisation of production. In this paper, we paid attention only a thing thought to be the most important point in the print process, an effective solution was obtained by devising the problem briefly. In the future, the establishment of an efficient production system is expected by applying the concept of the proposal method in also the manufacturing process of the semiconductor.
