iTrustEval: A framework for software trustworthiness evaluation with an intelligent AHP-based method.

Software trustworthiness is a composite reflection of software quality and dependability attributes that are defined in industrial standards (e.g., ISO 25010), indicating a software system is constructed and operated as expected. Trustworthiness evaluation has become increasingly vital for software production and its permission being used in industry. However, trustworthiness evaluation is challenging due to the absence of comprehensive models, systematic methods, and efficient tools. We present iTrustEval a framework for software trustworthiness evaluation with an intelligent analytic hierarchy process (AHP)based method. In iTrustEval an extensible trustworthiness model enabling on-demand integration with industrial trustworthy standards (such as ISO 25010 and Automotive SPICE in the current model) is proposed; an AHP based method is designed for the bottom-up measuring data fusion (where a hybrid missing-value recommendation engine is developed using both temporal-attenuation-mechanism based history data recommendation and matrix factorisation-based recommender system); and a prototypical tool has been developed. The applicability of iTrustEval is validated through a case study, and the results show it is sound in efficiency and effectiveness.
