Estimating the functionality of object oriented system using MCDM approach

Object oriented software system selection is an MCDM problem which is analyzed based on the expert's preference on different Parameters. Functionality attribute is one such parameter selected from Software quality model which consists of several other parameters by which quality of any Software can be analyzed. AHP tool is used for subjective weight analysis which is further validated using FTOPSIS technique on Functionality parameter. This analysis helps experts in selection of software systems whose concern is more about the functional operation of system. A MCDM model consists of AHP-FTOPSIS is proposed for ranking of alternatives based on the quantitative and subjective Parameters.
