The Trustworthiness Measurement Model of Component-Based Software Based on Combination Weight

Software trustworthiness is an important indicator to assess the quality of software and can be portrayed by the attributes of the software. The different attribute produces different influence on the software quality. Therefore, it is important to study the weight allocation for different attributes to measure software trustworthiness reasonably. Usually, the weight of trustworthy attributes is affected by two aspects, one is the assessment of experts and the other is the hidden information in attributes. The component-based software has become popular in the field of software engineering due to its advantages. So a trustworthiness measurement model of component-based software is proposed by combining the weights. Firstly, a new method of weight allocation for trustworthy attributes is proposed based on Fuzzy Analytical Hierarchy Process and the grey correlation method. Secondly, the trustworthiness measurement model of component-based software will be established based on the combination structures of components. Finally, the station ticketing system is used to illustrate the rationality of the model.
