Fuzzy multi-attribute decision making for software defect detection model evaluation

With the continuous expansion of the computer system application field, the complexity of software system is also improving. Software defect detection has gradually become an important research direction in the field of software engineering. At present, the mixed statistics and machine learning methods have been proved to be able to implement software defect detection models well. However, the evaluation index of the detection model is diverse and it is difficult to determine which model evaluation indicators are in line with the actual expectations. Aiming at this kind of problem, a software defect detection model evaluation method based on fuzzy multi-objective attribute decision making is proposed. First, extract the characteristics of software modules, use McCabe and Halstead software modules to measure attributes. Then select five common classification algorithms to establish software defect detection models, and obtain seven evaluation index values of each model. Further, based on fuzzy multi-objective attribute decision making method with fuzzy analytic hierarchy process (FAHP) to compare multiple objectives, and obtain the results of index determination. Finally, the fuzzy evaluation algorithm is used to convert the evaluation index of qualitative evaluation into quantitative evaluation to obtain the final decision evaluation value. The experimental results show the effectiveness and practicality of the method.
