TL;DR: A dynamic and visual “free‐search” type of interactive procedure for multiple‐objective linear programming that enables a decision maker to freely search any part of the efficient frontier by controlling the speed and direction of motion.
Abstract: A dynamic and visual “free-search” type of interactive procedure for multiple-objective linear programming is presented. The method enables a decision maker to freely search any part of the efficient frontier by controlling the speed and direction of motion. The objective function values are represented in numeric form and as bar graphs on a display. The method is implemented on an IBM PC/1 microcomputer and is illustrated using a multiple-objective linear-programming model for managing disposal of sewage sludge in the New York Bight. Some other applications are also briefly discussed.

TL;DR: A new visual interactive method for solving discrete multiple criteria problems based on the use of a reference direction, which is determined by the aspiration levels for the criteria specified by the decision maker, is proposed.

TL;DR: The fundamental concepts behind the use of heuristic optimization as a means of improving the behavior of systems as represented by system dynamics models are presented.
Abstract: This paper presents the fundamental concepts behind the use of heuristic optimization as a means of improving the behavior of systems as represented by system dynamics models. The philosophy of the approach is highlighted and the underlying software explained, as a prerequisite to developing some simple demonstration examples.

TL;DR: In this article, a multiple criteria model for finding the most preferred solution for the problem of pricing alcoholic beverages is developed, which includes three criteria: profit (max), consumption of absolute alcohol (min), and impact on the consumer price index.

TL;DR: It is recommended that the IS managers should critically re-evaluate and adjust their EUC strategies: an IC alone does not guarantee any success.

TL;DR: A results-oriented, action research OD change program was implemented in 80 largest banks of a major Finnish banking system as discussed by the authors, where individual top management teams were able to emphasize different aspects of change, including strategic changes, less operational changes, more changes emphasizing planning and implementation of changes, and more unplanned changes.
Abstract: A results-oriented, action research OD change program was instituted in the 80 largest banks of a major Finnish banking system. Using a results-oriented framework common to all and consensual decision making, individual top management teams were able to emphasize different aspects of change. It was hypothesized that, at the completion of the intervention strategy, high-performing banks would report more strategic changes, less operational changes, more changes emphasizing planning and implementation of changes, and more unplanned changes than would low performers. It was also hypothesized that some three years after completion of the intervention strategy, high performers would report more deep-seated changes than would low performers. Consensually based reports of changes indicated support for these hypotheses but with some qualifications. Implications of the findings are discussed.
