Fuzzy integrated evaluation for software reliability of air traffic control automatic system

In order to solve the problem that the software reliability of air traffic control automatic system （ATCAS） decreases due to the explosive increase of information processed by Civil Aviation of China, a fuzzy integrated evaluation method was adopted to evaluate the software reliability. The factors affecting the software reliability of ATCAS were analyzed with the proposed method, and the index system of software reliability of ATCAS was established. In addition, the analytic hierarchy process （AHP） and matter element analysis methods were combined to determine the weight of each factor. Moreover, the software reliability was evaluated with the fuzzy integrated evaluation method. The results of both example analysis and calculation show that the present evaluation method has some degree of effectiveness and operability, and can evaluate the software reliability of ATCAS objectively and correctly.
