Optimize Design and Analysis Based on the Marginal Utility of the Cost of Supply Inventory

The purpose of the spare parts inventory is used to maintain the normal operation of the equipment, the best metric to measure the merits of the spare parts inventory levels is the use of security equipment. Therefore, Under the constraint of the total supply of spare parts cost, based on spare parts of marginal utility analysis, here propose maintenance waiting time as the objective function of optimization models in maintenance waiting time.
