Optimal component selection based on cohesion and coupling for component-based software system

Abstract

In modular-based software systems, each module has different alternatives with variation in their functional and nonfunctional properties, e.g., reliability, cost, delivery time, etc. The success of such systems largely depends upon the selection process of commercial-off-the shelf (COTS) components. In component-based software (CBS) development, it is desirable to choose the components that provide all necessary functionalities and at the same time optimize nonfunctional attributes of the system. In this paper, we have discussed the multiobjective optimization model for COTS selection in the development of a modular software system using CBSS approach. Fuzzy mathematical programming (FMP) is used for decision making to counter the effects of unreliable input information.
