Aiming at the actuality that missile is inspected periodically and its life data together with the inspecting information are underutilized, this paper puts forward a case 2 interval-censored proportional hazards model to analyze the influence of key inspecting parameters on the failure rate of missile, moreover, a storage availability model under periodical inspection is established based on missile inspection and maintenance engineering practice. By adopting the prescriptive availability threshold as inspecting policy control limit, the inspecting period can be optimized according to the condition of missile and the problem that inspection-introduced failure caused by excessive inspection can be also effectively solved. Finally, a numerical example is illustrated to prove the effectiveness of the method.
