초록

Several regulations on converting reusable products are established in many countries, due to the emphasis on environmental issues on manufacturing. Many companies consider reusable and returned items in addition to purchasing new items. In this paper we suggest several algorithms to determine the near optimal quantities of items for converting and new items for purchasing. The reusable items are converted into end items, each facing normally distributed demand in a single period of interest. We develop a mathematical model and a genetic algorithm(GA) to compare the number of convertible units and new items to be purchased. Computational results demonstrate the efficiency of the developed algorithms.
