Research on Confirming the Weighted Value in Software Quality Model Based on Analytic Hierarchy Process

Some problems are existed in confirming the weighted value in the software quality model, for example, the method is relatively rough and how the abnormal value is rejected while judging the weighted value. Aiming at these problems, it is pointed out that the scientific hierarchy structure of quality characteristics and sub characteristics should be built based on the analytic hierarchy process. Through the construction of judgment matrix, single hierarchical arrangement, total hierarchical arrangement and consistency check, the comprehensive weighted value of sub characteristics of bottom quality will be confirmed. Then by the extreme judgment rejecting method, the abnormal judgment value will be rejected to avoid the unreasonable comprehensive weighted value. Finally, by adopting this method in the test of one certain communication system software, the scientificity and rationality is verified.
