Abstract: According to the information equivalence principle, the reliability assessment method was studied for the system comprising binomial units and exponential units.The basic conversion models of entropy method were established for the binomial system or the exponential system based on individual test information.Meanwhile, the conversion formulas were presented for the binomial information and exponential information, and the availability of the method was illustrated comparatively through analysis of the examples and assessment results.
