Recently, the concern of software quality increases rapidly. Although there have been many efforts to establish standards for software quality, such as ISO/IEC 9126, they provide only a framework for quality characteristics and evaluation process. They do not provide practical guidance for deriving reasonable weight value criteria for quality evaluation. This paper presents a method to draw the quantitative weight values from evaluator’s subjective data in software evaluation in compliance with ISO/IEC 9126 standard. To eliminate evaluators’ subjectiveness and uncertainty, the Dempster-Shafer (D-S) theory is improvised and utilized. The D-S theory is improved with merge rule to reduce the bias of weight value when they are merged with other evaluator’s weight value. The proposed merge rule has been tested for it’s effectiveness with actual evaluation data.
