Abstract
The problem situation can be observed when the capability of several components on a single machine decrease during the scheduling period and need maintenance action. Since the lifetime is variation, that action often interrupts the production process. The solution can be obtained by grouping the maintenance action with determine the number of the group, component on the group, and scheduling the group to the shop. However, that decision must consider the production plan, i.e., the number of the batch, batch size, and schedule the batches. We propose the algorithm to integrate between both of these two problems, so the total actual flow time minimize. The result of experiments shows that the proposed algorithm could increase the performance effectively.
