| Abstract: |
| When the number of rockets is small or the cost is high, the test information of each component is much and the system-level product information is less. It is difficult to realize the comprehensive assessment of system reliability accurately and effectively. Give the equivalent conversion method from component test information to system-level test information based on CMSR. Integrate the system-level test information to achieve reliability evaluation. Consider the test data of the component inspection test during storage Comprehensively. Realize the conversion of component test information to system-level test information based on the CMSR method. Integrate the system-level test information to achieve reliability evaluation. Under different confidence levels, Considering the test data of the rocket components and the system-level test data, give the mission reliability of the rocket after many years of storage to provide the support for whether the rocket can continue to be used.In the case of little or no test data in the system, converting the test information of the components into system-level test information. Use the success-failure reliability calculation formula to calculate the mission reliability of the system-level product after a certain number of years of storage. |
