Software Reliability as User Perception: Application of the Fuzzy Analytic Hierarchy Process to Software Reliability Analysis

摘要

Software Quality is a multidimensional concept for which Reliability is considered as a key attribute. Notwithstanding, due to its conceptual complexity, there is no common agreement on what Software Reliability is, thus different stakeholders use a variety of Software Reliability views. With the aim to improve our understanding of what Software Reliability means for industrial stakeholders as well as that of contributing to enhance the industrial applicability of Software Quality Models we propose approaching Software Reliability analysis by using structural model based on representative International Standards, which are industry-oriented. As analysis method, since interested on stakeholders' vision of Reliability we will apply the Fuzzy Analytic Hierarchical Process (FAHP) which is designed to manage human assessment, always characterized by a certain degree of vagueness and subjectivity. The rationality of the proposed model and feasibility of the analysis method is proved by the application on a very large industrial system which provides empirical evidence on the conceptual descriptiveness capturing stakeholders' views and industrial applicability in an efficient manner.
