Abstract: Aiming at the problems of classical evaluation methods and traditional Bayesian evaluation method, a testability evaluation method was proposed based on multi-source information fusions for small sample problem of current complex equipment testability evaluations. The reliability and credibility of multi-source informations were comprehensively considered, and the problems of the reliability of multi-source informations on the testing level of complex equipment were solved, as well as the problems that small sample field test informations were submerged due to different characteristics of multi-source informations and field test informations when the fusions were solved after the posterior distributions. Finally, the testability evaluation of a certain type of fire control system was taken as an example, and compared with the classical evaluation method and the traditional Bayesian evaluation method. The results show that the testability evaluation method based on mult-source information fusions is more reasonable and has more advantages when dealing with field test informations for small samples.
