This paper presents a new mathematical model for a bi-objective job shop scheduling problem with sequence-dependent setup times that minimizes the weighted mean completion time and the weighted mean tardiness time. For solving this multi-objective model, we develop a fuzzy multi-objective linear programming (FMOLP) model. In this problem, a proposed FMOLP method is applied with respect to the o...

wastewater planning management is a complex problem involving agricultural, rural and industrial interests. in countries facing rapid population growth, identifying methods that can allow them to take good decisions among several competitive alternatives is of utmost importance. the purpose of this paper is to present a methodology for a wastewater planning management system using a multi-c...

We present the necessary and sufficient conditions on ordinal preferential information provided by the decision maker for the existence of a 2-additive capacity such that the Choquet integral w.r.t. this capacity represents the preference of the decision maker. These conditions help the decision-maker to understand the main reasons of the recommendations made when inconsistencies occur in his p...

Cheap talk models provide a strategic analysis of information transmission between the expert and the decision maker when their preferences are not perfectly aligned. Although the majority of these models analyze the case of a single decision maker, in many important settings the decision-making authority is shared between several agents. Here we consider a commonly used procedure: ultimatum ba...

This paper integrates the theory of institutional economics and the task-technology fit model in order to theorize about DSS success (defined in terms of DSS use and decision quality). Institutional economics (Veblen 1899/1912, Ayres 1944 and Bush 1986, 1987) posits that human behavior is either instrumental (rational and associated with “getting a living”) or ceremonial and associated with cus...

A decision maker must divide a prize between multiple agents. The prize may be divisible (e.g., a budget, pork-barrel spending) in which case he prefers to award larger shares of the prize to relatively more-qualified agents, or it may be non-divisible (e.g., jobs, college admissions) in which case he prefers to award the limited number of prizes to the most-qualified agents. He is, however, ex...

There is a finite set of states: Ω = {ω1, . . . , ωn} where n ∈ N. An experiment P is an n ×N matrix {Pij}i=1,...,n;j=1,...,N , where N ∈ N, such that Pij ≥ 0 for all i, j and ∑N j=1 Pij = 1 for all i = 1, . . . , n. We shall call such a matrix a “Markov matrix.” The interpretation is that Pij is the probability of observing experiment outcome j in state ωi. The decision maker conducts experime...
