Achieving dependability has always been a challenging task for the software developers. Ensuring the selection of suitable dependability attributes for the software development is crucial for the development of dependable software and to maintain trust among software developers. For multi criteria decision making a very helpful tool is identified called Fuzzy Analytic Hierarchy Process (FAHP). For the comparison of different factors and sub-factors (attributes) and to know the impact of one factor over the other the FAHP has been identified by researchers. The main objective of this paper is to implementation of Fuzzy Analytic Hierarchy Process for the estimation of software dependability, By which we can identify the most suitable dependability attributes and ranked them as per their weight-ages. The Fuzzy Analytic Hierarchy Process uses a defined range of values rather than a single crisp value to vanish the decision maker’s uncertainty. Using the definite range of values, the decision makers can choose the value that shows his confidence and also they can specify their stance like optimistic, pessimistic or moderate. This paper reveals the implementation of Fuzzy AHP technique to calculate the weight-ages of dependability attributes and ranked them. This study can be a guide of the methodology to be implemented by software developers for the selection of appropriate dependability factors and sub-factors for the development of dependable software
