Maintainability Configuration for Component-Based Systems Using Fuzzy Approach

Abstract

Maintenance is one of the extremely important and tricky missions in the area of component-based software. Numerous maintainability models are proposed by the scientist and researchers, to reduce the cost of maintenance, for improving the excellence and life period of a component-based system. Various quality models have been discussed briefly to show importance of maintainability. This research will facilitate the software designer to assemble maintainable component-based softwares. The proposed configuration confers a fuzzy-based maintainability model that chooses four fundamental features that enormously influence maintainability of component-based software system, i.e., Document Quality, Testability, Coupling, and Modifiability (DTMC). MATLAB's fuzzy logic toolbox is utilized to implement this configuration and output values are confirmed using center of gravity formula, as we have taken centroid defuzzification method. For a particular set of input, output provided by the model is 0.497 and output value from center of gravity formula comes up to be 0.467 which is around the value specified by the model.
