Research on equipment failure rate forecasting based on gray-linear regression combined model

The paper researches math model about equipment failure rate, in order to forecast exactly equipment failure rate and advance equipment integrity rate and mission success rate and reserve rationality maintenance material. The paper establishes the gray-linear regression combined model and conceives math formula between equipment failure rate and use time. At the same time, the gray-linear regression combined model is proved to be valid and more accurate forecasting method compare with single forecasting model through practical example.
