Calculation and Application of Environment Conversion Factors for Weibull Distribution

Objective To fuse the test data under different environmental conditions. Methods This paper discussed the environment conversion factors for Weibull distribution which is the most widely used distribution. First, the environment conversion factors for Weibull distribution were defined. Then, the environment conversion factors were calculated by the maximum likelihood estimation. Results Calculation results related to environmental factors were obtained, based on which the methods and procedures for application of environment conversion factors were given. Conclusion Data fusion under different environmental conditions by environmental factors of Weibull distribution was reasonable, so as to achieve the purpose of expanding the test sample.
