This paper considers the use of subsidies or tax credits for the purpose of increasing the utilization of underemployed or underutilized resources. The particular formulation studied is the subsidy which is associated with changes in the level of usage of a particular input factor. The effects...

The paper introduces restructurable modelling of negotiation aimed at supporting decision situations with an evolving structure. The theoretical framework of such models is presented by means of a rule-based formalism. This framework encompasses both qualitative and quantitative models, and the...

We develop an interactive method for multiple objective linear programming based on aspiration levels of a decision maker. The method assumes an unknown pseudoconcave preference structure of a decision maker throughout the decision process, and the decision maker's ability to select a preferred...

This paper develops a method for interactive multiple objective linear programming assuming an unknown pseudo concave utility function satisfying certain general properties. The method is an extension of our earlier method published in this journal (Zionts, S., Wallenius, J. 1976. An interactive...

Randomly-generated linear programming problems of three different types and five different sizes were solved by the criss-cross method and by the simplex method. One hundred problems of each type and size were solved, and the results are overwhelmingly favorable to the criss-cross method. An...

This paper presents a class of methods, called constraint proposal methods, for generating Pareto-optimal solutions in two-party negotiations. In these methods joint tangents of the decision makers' value functions are searched by adjusting an artificial plane constraint. The problem of...

An interactive method employing pairwise comparisons of attainable solutions is developed for solving the discrete, deterministic multiple criteria problem assuming a single decision maker who has an implicit quasi-concave increasing utility (or value) function. The method chooses an arbitrary...

One approach for solving decision problems involving multiple objectives is interactive optimization. Methods based on this approach assess the decision maker's preference structure interactively, typically based on pairwise comparisons and tradeoffs, and guide the search process toward...

A new efficient system of representing the decision-maker's preference structure in solving multicriteria integer programming problems is developed. The problem is solved by an interactive branch-and-bound method that employs the procedure of Zionts and Wallenius (Zionts, S., J. Wallenius. 1983....
