Abstract: To specify the extent of outsourced maintenance activities and to determine the service contract cost for key equipments in mechanical manufacturing enterprises, both two contract options and a outsourced maintenance cost model were presented. Subject of equipment management was analyzed, and research object was defined. Then, two contract options were proposed, including all-inclusive strategy and selective strategy. A cost model of maintenance outsourcing was also established. The reasonable inspection interval based on required reliability was given by using the delay time maintenance theory, and the expected number of failures and the expected number of defected identified in preventive maintenance activities were given as well. The expected profits for both customer and agent under different strategy were calculated. Finally, a numerical example was analzyed.

Key words: mechanical manufacturing enterprises, key equipments, maintenance, outsourcing, inspection interval, delay time
