Essays on multiple criteria decision making and negotiations
MetadataShow full item record
This dissertation focuses on decision making and decision support systems, and consists of four related studies. In the first study, a web version of the Aspiration-level Interactive Method (AIM), WebAIM, is developed and made available at http://mgt2.buffalo.edu/webaimU . We demonstrate the usage of the program and introduce the features of WebAIM through a house selection problem. In the second study, we explore certain properties of AIM and extend the concept of robustness of solutions in AIM. We map well-diversified aspiration levels to their corresponding most preferred alternatives, and find that a majority of aspiration levels are mapped to relatively few alternatives. Next, we apply the techniques developed in Multiple Criteria Decision Making to a negotiation problem. We consider a one-to-many negotiation problem such as a house-purchasing process in which there is one buyer and many sellers. Using the Best Alternative to a Negotiated Agreement (BATNA) as a dynamic measure of negotiating strength, we develop a systematic quantitative iterative approach to assist in the negotiation process. Finally, we consider generating random uniformly-distributed weights for the simulation of additive p-criteria decision models. The study reviews and validates several approaches for generating random weights with and without linear constraints. Some obvious approaches do not work well at all.
