Abstract:

Warranty period is a frontier research in the field of international reliability. Based on the current situation of the naval shipborne missile system at the initial stage of service and the characteristics of equipment warranty research field, the necessity of quantitative modeling of shipborne missile system fault characteristics is demonstrated. By using the field data and using linear regression fitting, it is found that the failure rate of shipborne missile system is more similar to the two parameter Weibull distribution, and the failure rate function and parameters of shipborne missile system are obtained. The global optimal warranty period model and the equal warranty period model of shipborne missile system are established respectively. The model is solved by using the field data. The global optimal warranty period solution and the equivalent warranty period solution are consistent with the modeling and research objectives, which can provide sugges tions for the Navy and the manufacturer to adjust and optimize the initial warranty period of shipborne missile system through negotiation, promote the research and reform of shipborne missile system warranty.

Key words: warranty period, shipborne missile system, two parameter Weibull distribution, global optimal warranty model, equal warranty model
