Abstract�� The assessment of TPS (test program set) diagnostic capability is one of the key means for TPS quality assurance. According to the comprehensive assessment problem of TPS diagnostic capability, a new knowledge fusion method based on D-S(Dempster-Shafer) evidence theory is developed. The rationale of D-S theory is introduced at first. The mathematical model and framework of TPS diagnostic capability assessment is proposed. The BPAF (basic probability assignment functions) definition and decision of TPS diagnostic capability feature based on K-S test (Kolmogorov-Smimov test) is described in detail. The process of TPS diagnostic capability assessment is given. At last an example is shown to assess an avionic equipment TPS. Result shows that D-S theory can effectively consider multi-features of TPS and decrease the decision uncertainty region.
