To reflect the diversification of consumers' needs and to survive in the severe competitive environment, a grate deal of effort has been paid by manufacturers. Respecting the background, importance of effective lot sizing has been focused. Although variety of lot sizing algorithms has been proposed, most of their objective functions are based on time and quantity criteria. However, the most important objective function is varied time by time in the real manufacturing environment. Product cost is calculated by integrating results of all activities in production processes. As a new simulation environment for evaluating the performance of whole manufacturing systems, a concept of Distributed Virtual Factory (DVF) has been proposed. By performing simulation with DVF, any information can be obtained. In this study, we propose an effective lot sizing methodology which performs Activity Based Costing (ABC) and minimizes product cost directly. We clarify the validity of the proposed lot sizing method through simulation experiments with DVF.
