Abstract: Aiming at the problem that the traditional information could not calculate one kind of evaluation system directly for the inherent characters of its system range in the Information Axiom (IA) based product-service system evaluation,the information axiom evaluation method was proposed under the hybrid uncertain condition of the system range as random variable and design range as the fuzzy variable.A hybrid uncertain index model for coexistence of fuzziness and randomness was built.Based on a fuzzy simulation method,information content integration algorithm with fuzzy boundaries was proposed.A crane machine product service system evaluation was taken as the example to verify the effectiveness on service evaluation expression by comparing with traditional information axiom method,and the correctness with practicability were also proved.
