空管自动化系统软件可靠性的模糊综合评价

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

针对中国民航空管信息处理量爆炸式增长导致空管自动化系统软件可靠性降低的问题,提出了采用模糊综合评价法对软件可靠性进行评估的方法.对影响空管自动化系统软件可靠性的因素进行了分析,构建了系统软件可靠性的指标体系,采用层次分析法和物元分析法相结合的方式对各因素进行了权重的确定,并运用模糊综合评价法对软件可靠性进行了评估.实例分析及计算结果表明,该评估方法具有一定的有效性和可操作性,能够客观准确地评估空管自动化系统软件的可靠性.

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.
