AbstractThis paper investigates the two‐person zero‐sum multiple payoff game in which the objective is to minimize a player's total underachievement from a fixed set of goals. It is demonstrated that a previous formulation of this problem can be substantially simplified.

This paper illustrates how the goal programming problem with fuzzy goals having linear membership functions may be formulated as a single goal programming problem. Also, a previously defined method for dealing with fuzzy weights for each of the goals is re‐examined.

The inequities of the present system of rules in jai alai are documented on the basis of empirical information and theoretical results from a Monte Carlo simulation model. Some suggestions are made for changing the rules in order to make the game more equitable for both players and bettors. The simulation model is used to compare the effectiveness of the suggested rules with that of the present rules.

ABSTRACTThis paper describes the use of multiattribute decision making by the U.S. Coast Guard when choosing the most appropriate auxiliary device to use on an icebreaker. Five different missions of icebreakers are defined, and the objectives and attributes that describe the effectiveness of each auxiliary device in accomplishing these missions are established. For each geographical area of interest, the missions are weighted using the analytical hierarchy process. Also, group utilities are developed for attribute vectors in order to incorporate the judgments of different icebreaker operators.

This paper examines the relationship between supervisors' and project leaders' perceptions about the smoking behavior of their subordinate employees and their performance appraisals of their employees. Those who were perceived to be smokers were rated lower than those perceived to be nonsmokers on four of nine job performance measures when controlling for age, race, and gender. The findings suggest smoking stigma may negatively affect the perceptions of one's overall job performance, especially in terms of one's professional comportment, working relations with others, and dependability.
