A fuzzy based approach for the selection of goals in goal oriented requirements elicitation process

Goal selection in goal oriented requirements elicitation process (GOREP) like KAOS, i*, AGORA etc., is a multi-criteria decision making problem. In literature, we identify that existing GOREP do not support to choose and adopt a goal out of the alternatives of the decomposed goals when multi-criteria decision making approaches are used and stakeholders' preferences are in the form of linguistic variables. Therefore, this paper presents a fuzzy based approach to address the above issue by using alpha-level weighted F-preference relation in group decision making process. Finally, the utilization of the proposed approach is demonstrated with the help of an example.
