Study On Integration Service Mode And Operating Methods Of Automotive Product Warranty

Based on the current research status of product warranty management and theexisting problems in the manufacturing warranty management, this paper studies theinfluence mechanism and characteristics of product warranty management through thethoughts of integration and systematization. Starting from the point of view of therepresentative automobile manufacturers, the integrated auto product warranty servicemode and the operating methods are both studied in-depth. The main findings are asfollows.First, by carrying out a detailed summary and comment on the current researchstatus of product warranty management, the main research direction is proposed. Onthat basis, the central issues of the approach in this paper are raised.Second, comparing the product warranty cost in Chinese manufacturingenterprises with international standards, the weak product warranty management levelin our country is revealed. An empirical study is conducted to develop the theoreticalstructure of the impact factors of product warranty management in the form ofquestionnaire. Then the path of product warranty management influence mechanismis obtained, which lays the groundwork for improving the manufacturing productwarranty management.Thirdly, by analyzing the existing deficiencies of the current warranty servicemode in service object and service technology, the cloud manufacturing technology isintroduced to develop the framework of auto product warranty service mode. Theimplementation technique is also proposed including warranty knowledge integrationin cloud-edge, life-cycle cost prediction and the critical operation strategies.Fourthly, the characteristics of auto product warranty service are analyzed. Onthat basis, the problem of warranty service facility location based on stochasticprogramming. Under the premise of considering the random variable—warrantyservice demand, the service facility location model as well as the intelligencealgorithm on the basis is developed to maximize the service coverage.Fifthly, the auto product warranty service process is analyzed. On that basis, theGeneralized Stochastic Petri net model of the process is developed to conduct performance analysis. The bottlenecks of the process are identified to provide thebasis for the design, plan and evaluation of the auto product warranty service process.Sixth, the sales of automotive products under the different market shares areestimated from the point of view of product life cycle. According to the informationincluding the part reliability and product group mode, the demand of spare parts of thesame family of the auto product is predicted. Combined with the corresponding theoryof inventory management, the paper designs the spare parts inventory method of autoproduct in the same family of automobile manufacturing enterprises.Seventh, by setting the agent reward and punishment mechanism, the influenceof warranty service time on the interests of auto manufacturers and maintenanceservice providers is analyzed. The multi-objective optimization model is developed tomaximize the service profits and the service level of the maintenance service provider.An intelligence algorithm is proposed to solve the problem and provide the decisionsupport for designing a warranty service contract of bailment by manufacturers.
