An Improved Fuzzy Synthesis Evaluation Algorithm for Software Quality

Based on the practice of software quality evaluated by the fuzzy synthesis evaluation algorithm, it is chiefly analyzed that the reason a lot of available information has been lost by calculating method of ´taking big and taking small value´ in the fuzzy algorithm model, and shortage and limitation to be resulted in the simplification and the absolutization of evaluation result in the evaluation process are especially discussed. The operation ´taking big and taking small value´ in original algorithm model is changed into matrix multiplication operation with original algorithm structure, and the normal distribution function is introduced for the measurement of the metric elements, these are used to establish a new mathematical model to suit modern software quality evaluation requirements. It is very useful and effective to apply the new model to software quality computing evaluation. And that it is fruitful to improve the accuracy, practicability and reliability as well as flexibility of software quality evaluation.
