Computing tournament solutions using relation algebra and RelView
Berghammer, Rudolf; Rusinowska, Agnieszka; de Swart, Harrie - In: European Journal of Operational Research 226 (2013) 3, pp. 636-645
We describe a simple computing technique for the tournament choice problem. It rests upon relational modeling and uses …, the minimal covering set, the Banks set, and the tournament equilibrium set are delivered. We present an example of a … tournament on a small set of alternatives, for which the above choice sets are computed and visualized via RelView. The technique …

Strategic bidding of offer curves: An agent-based approach to exploring supply curve equilibria
Kimbrough, Steven O.; Murphy, Frederic H. - In: European Journal of Operational Research 229 (2013) 1, pp. 165-178
complicated to be analyzed using traditional economic theory. In addition, we demonstrate computationally that, by using …

Stochastic linear programming games with concave preferences
Uhan, Nelson A. - In: European Journal of Operational Research 243 (2015) 2, pp. 637-646
We study stochastic linear programming games: a class of stochastic cooperative games whose payoffs under any realization of uncertainty are determined by a specially structured linear program. These games can model a variety of settings, including inventory centralization and cooperative...

Strategizing niceness in co-opetition: The case of knowledge exchange in supply chain innovation projects
Nasr, Eman S.; Kilgour, Marc D.; Noori, Hamid - In: European Journal of Operational Research 244 (2015) 3, pp. 845-854
In this paper, we take a novel approach to address the dilemma of innovation sharing versus protection among supply chain partners. The paper conducts an exploratory study that introduces factors affecting a firm's optimum supply chain innovation strategy. We go beyond the conventional...

The golden number and Fibonacci sequences in the design of voting structures
Freixas, Josep; Kurz, Sascha - In: European Journal of Operational Research 226 (2013) 2, pp. 246-257
Some distinguished types of voters, as vetoes, passers or nulls, as well as some others, play a significant role in voting systems because they are either the most powerful or the least powerful voters in the game independently of the measure used to evaluate power. In this paper we are...

Revisiting a game theoretic framework for the robust railway network design against intentional attacks
Perea, Federico; Puerto, Justo - In: European Journal of Operational Research 226 (2013) 2, pp. 286-292
This paper discusses and extends some competitive aspects of the games proposed in an earlier work, where a robust railway network design problem was proposed as a non-cooperative zero-sum game in normal form between a designer/operator and an attacker. Due to the importance of the order of play...

Cooperative advertising models in supply chain management: A review
Aust, Gerhard; Buscher, Udo - In: European Journal of Operational Research 234 (2014) 1, pp. 1-14
This paper reviews articles on cooperative advertising, a topic which has gained substantial interest in the recent years. Thereby, we first briefly distinguish five different definitions of cooperative advertising which can be found in operations research literature. After that, we concentrate...

Achievable hierarchies in voting games with abstention
Freixas, Josep; Tchantcho, Bertrand; Tedjeugang, Narcisse - In: European Journal of Operational Research 236 (2014) 1, pp. 254-260
It is well known that he influence relation orders the voters the same way as the classical Banzhaf and Shapley–Shubik indices do when they are extended to the voting games with abstention (VGA) in the class of complete games. Moreover, all hierarchies for the influence relation are achievable...

A three-dimensional voting system in Hong Kong
Cheung, Wai-Shun; Ng, Tuen-Wai - In: European Journal of Operational Research 236 (2014) 1, pp. 292-297
The voting system of the Legislative Council of Hong Kong (Legco) is sometimes unicameral and sometimes bicameral, depending on whether the bill is proposed by the Hong Kong government. Therefore, although without any representative within Legco, the Hong Kong government has certain degree of...

Partnership formation with age-dependent preferences
Alpern, S.; Katrantzi, I.; Ramsey, D.M. - In: European Journal of Operational Research 225 (2013) 1, pp. 91-99
We analyze a model of partnership formation in which players’ preferences are based on the age of a prospective partner. There are two classes of individuals, called for convenience here male and female. Males and females are fertile for the same length of time, normalized to one unit. A male...
