Optimization of Performance Guarantee Strategies for Multi-objective Two-Dimensional Warranty Equipment
To enhance the enthusiasm of manufacturing units for participating in equipment warranty and improve the effectiveness of equipment warranty,a performance guarantee strategy is adopted for the two-dimensional warranty equipment that employs regular preventive maintenance.Based on the two-di-mensional failure rate function of the equipment,the warranty cost model and equipment availability model are established.By constructing a benefit function that includes incentive measures,the warranty costs of the manufacturing units are linked to the minimum availability level required by the troops,and a multi-objective two-dimensional warranty equipment performance guarantee decision model is developed.The ef-fectiveness of the model is verified through the numerical example of a certain type of vehicle equipment with the simulated annealing algorithm.The comparative analysis indicates that the multi-objective per-formance guarantee strategy can effectively improve the manufacturing units'profits while ensuring equip-ment availability,making it a win-win warranty strategy for both the manufacturing units and the troops.In addition,the sensitivity analysis provides management recommendations for the manufacturing units to carry out performance guarantee and guidance for implementing proposed performance guarantee strategies.
