 Interactive multicriteria linear programming: An extension of the method of Zionts and WalleniusR. Ramesh, Mark H. Karwan and Stanley Zionts Naval Research Logistics (NRL), 1989, vol. 36, issue 3, 321-335 Abstract: This article presents an extension of the interactive multicriteria linear‐programming method of Zionts and Wallenius [see Management Science, 29(5) (1983)]. The decision maker's underlying utility function is assumed to be pseudoconcave, and his preference structure is assessed through pairwise comparison questions. In the method of Zionts and Wallenius, the decision maker's preference structure is represented as constraints on the weights on the objectives derived from his responses. This representation is only a linear approximation to the underlying nonlinear utility function. Accordingly, inconsistency among the constraints on the weights arises while solving the problem. Therefore, some of the constraints have to be dropped, resulting in a loss of information on the preference structure, and hence an increase in the total number of questions. In this article we develop a hybrid representation scheme to avoid this problem. The proposed scheme is implemented within the algorithmic framework of the method of Zionts and Wallenius, and its underlying theory is developed. Computational results show that the number of questions required by the Zionts and Wallenius method can be sinificantly reduced using the proposed scheme.
