Multi-Person Decision-Making for Requirements Prioritization using Fuzzy AHP

摘要

The success of a system depends upon how effectively it accomplishes its intended purpose by meeting all stakeholders' concerns pertaining to conflicting requirements such as cost, size, time, performance etc. Conflicts occur because the requirements are individually refined, without consideration to how they may impact the other stakeholders in the system. As the stakeholders' concerns are uncertain and subjective in nature, this paper proposes a novel approach to prioritize the conflicting requirements using Fuzzy Analytic Hierarchy Process and an alpha cut. A total compatible ordering is achieved to resolve the conflicting preferences of the stakeholders. It assists the project managers to develop a system that meets the expectations of all the stakeholders. A case study of the Travel Management Planning Website is presented to illustrate the application of the methodology.
