Heuristic Concentration and Tabu Search: A Nose to Nose Comparison

Rosing, K.E.; ReVelle, C.S. - 1997

In 1997 two papers_new applying the metaheuristics Tabu Search (TS) and Heuristic Concentration (HC) tothe p-median problem were published in consecutive volumes of the European Journal of OperationalResearch. Here we apply the method of HC some of the data sets which were used for...

Scheduling and combinatorial auctions: Lagrangean relaxation-based bonds for the WJISP

Elendner, Thomas - 2003

In this paper we consider the following problem: a Company wants to sell consecutive time slots on a single machine. It wants to maximize the revenues, whereby market prizes are not known. Additionally, consider a number of potential buyers of those time slots providing each at least one job....

Cost Sharing under Uncertainty: An Algorithmic Approach to Cooperative Interval-Valued Games

Kimms, Alf; Drechsel, Julia - In: BuR - Business Research 2 (2009) 2, pp. 206-213

Recently, Branzei, Dimitrov, and Tijs (2003) introduced cooperative interval-valued games. Among other insights, the notion of an interval core has been coined and proposed as a solution concept for interval-valued games. In this paper we will present a general mathematical programming algorithm...

On the revealed preference analysis of stable aggregate matchings

Demuynck, Thomas; Salman, Umutcan - In: Theoretical Economics 17 (2022) 4, pp. 1651-1682

Echenique, Lee, Shum, and Yenmez (2013) established the testable revealed preference restrictions for stable aggregate matching with transferable (TU) and non-transferable utility (NTU) and for extremal stable matchings. In this paper, we rephrase their restrictions in terms of properties on a...

Stochastic linear programming with a distortion risk constraint

Bazovkin, Pavel; Mosler, Karl - 2011

Linear optimization problems are investigated whose parameters are uncertain. We apply coherent distortion risk measures to capture the violation of restrictions. Such a model turns out to be appropriate for many applications and, principally, for the mean-risk portfolio selection problem. Each...

Relative performance evaluation in a multi-plant firm

Luporini, Annalisa - 2005

We analyze optimal compensation schedules for the directors of two plants belonging to the same owner and producing the same good but serving geographically differentiated markets. Since the outcome of each director depends on his own effort and on a random variable representing market...

Is there an optimization in bounded rationality? : The ratio of aspiration levels

Beckenkamp, Martin - 2004

Simon's (1955) famous paper was one of the first to cast doubt on the validity of rational choice theory; it has been … supplemented by many more papers in the last three and a half decades. Nevertheless, rational choice theory plays a crucial role in … classical and neoclassical economic theory, which presumes a completely rational agent. The central points characterizing such …
