Value-based decision is very complicated since many parties involved. Where a number of stakeholders are involved in choosing a single alternative from a set of solution alternatives, there are different concern caused by differing preferences, experiences, and background. Therefore, a negotiation is required to enable each stakeholder to evaluate and rank the solution alternatives before engaging into negotiation with the other stakeholders. Decision techniques applied to determine the relative value of the alternative solutions for performing the function. The results demonstrate a comparison of aggregation and coalition formation in a multi criteria group decision and negotiation. It further emphasizes the importance of performance evaluation in the design process and value-based decision. ©2009 IEEE.
