In order to determine a cost evaluation method applicable to investment in plant-equipments and management in grain drying facilities, the authors made the efficiency analysis at some practical grain drying facilities applying the pay-back period method and the rate of return method. Based on this, a computation model was proposed to be able to calculate appropriate drying-charges. Experimental drying-charges induced from a simulation upon this computation model were compared with the charges actually applied at 43 drying facilities, and some discussions were made. The results made it clear that the acutual drying-charges could compensate in average only 61 percent of the charges to meet the drying facilities management. However, in some facilities performing high operation rate the running cost became lower enough to withdraw the capital invested.
