Agent-oriented software development is a recent paradigm of analyzing, designing and developing software systems that aims to develop a system as a collection of autonomous interacting agents. Agent-oriented requirement engineering models requirements of a system in terms of goals and tasks that various software agents would achieve to accomplish the goals of that system. In an agent based project, various stakeholders may have different concerns and priorities over implementation of various agents due to time and budget constraints. Also, the requirements of stakeholders are often subjective and are accompanied with vagueness and uncertainty. This paper therefore utilizes fuzzy decision model named as Multi-Person Decision-Making Model to negotiate and integrate the requirements of various stakeholders. This integrated set of requirements facilitates the developers in prioritizing and deciding which agents are viable to achieve in the limited constraints.
