With economic growth, municipal refuse as well as electric energy consumption of the refuse disposal plants are rapidly increasing. Therefore, the improvement of refuse disposal plants and the conservation of energy have become the most important issues in the refuse disposal sector in Japan. Recently, the refuse fired power plants have been constructed at many local municipalities. However, some plants can not help disposing of the refuse at a high cost.
In this paper, in order to minimize the total cost necessary for refuse disposal, a linear programming model of the wide-area operation is presented on the basis of the ten existing refuse disposal plants in Aichi prefecture. This operation cuts down the total cost by about 6 hundred million yen and increases the total electric energy by about 3 GWh compared with the actual values under the electricity sales price 10 yen/kWh and the unit price of transportation of refuse 43 yen/ton/km.
