In this study, a method of production control based on levelizing production is developed to reduce tardiness of production to required orders under short due date. Levelizing production is one of significant production systems to stably produce different products in the mixed production and to reduce excessive process inventory. We proposed production control of multi-products to reduce tardiness of required orders in levelizing production. The proposed production control is based on decision process of the required amount of products from orders in the line. Two step process is developed to generate the order of products and the amount of products: the process to minimize tardiness of predetermined products and the process to minimize tardiness of ordered products. Mathematical model is concreted to resolve the two step process. In this paper, the characteristics of the proposed method is explained and the numerical experiment is performed to evaluate the performance of the method.
