Operations research models for coalition structure in collaborative logistics

Guajardo, Mario; Rönnqvist, Mikael - In: European Journal of Operational Research 240 (2015) 1, pp. 147-159

Given a set of players and the cost of each possible coalition, the question we address is which coalitions should be formed. We formulate mixed integer linear programming models for this problem, considering core stability and strong equilibrium. The objective function looks for minimizing the...

Infrastructure security games

Baykal-Gürsoy, Melike; Duan, Zhe; Poor, H. Vincent; … - In: European Journal of Operational Research 239 (2014) 2, pp. 469-478

Infrastructure security against possible attacks involves making decisions under uncertainty. This paper presents game theoretic models of the interaction between an adversary and a first responder in order to study the problem of security within a transportation infrastructure. The risk measure...

Robust equilibria in location games

Buechel, Berno; Roehl, Nils - In: European Journal of Operational Research 240 (2015) 2, pp. 505-517

In the framework of spatial competition, two or more players strategically choose a location in order to attract consumers. It is assumed standardly that consumers with the same favorite location fully agree on the ranking of all possible locations. To investigate the necessity of this...

Quality and entry deterrence

Karaer, Özgen; Erhun, Feryal - In: European Journal of Operational Research 240 (2015) 1, pp. 292-303

We analyze the role of quality, which we define as an attribute of a product that increases consumers’ willingness to buy, as a competitive tool in a quality-price setting. We consider an incumbent’s entry-deterrence strategies using quality as a deterrent when faced by a potential entrant....

Cooperation in assembly systems: The role of knowledge sharing networks

Bernstein, Fernando; Gürhan Kök, A.; Meca, Ana - In: European Journal of Operational Research 240 (2015) 1, pp. 160-171

production costs. In the first stage of the game, which is modeled as a non-cooperative game among suppliers, suppliers make … knowledge sharing. We model this knowledge exchange as a cooperative game among suppliers in which, as a result of cooperation …, all suppliers achieve reductions in their fixed costs. In the non-cooperative game, the suppliers anticipate the cost …

Competition through capacity investment under asymmetric existing capacities and costs

Yang, Shu-Jung Sunny; Anderson, Edward James - In: European Journal of Operational Research 237 (2014) 1, pp. 217-230

This paper discusses the way that different operational characteristics including existing capacity, scale economies, and production policy have an important influence on the capacity outcomes when firms compete in the market place. We formulate a game-theoretical model where each firm has an...

Service rate control of closed Jackson networks from game theoretic perspective

Xia, Li - In: European Journal of Operational Research 237 (2014) 2, pp. 546-554

average payoff. We formulate this problem as a non-cooperative stochastic game with multiple players. By utilizing the problem …

Measuring and rewarding flexibility in collaborative distribution, including two-partner coalitions

Vanovermeire, Christine; Sörensen, Kenneth - In: European Journal of Operational Research 239 (2014) 1, pp. 157-165

Horizontal collaboration among shippers is gaining traction as a way to increase logistic efficiency. The total distribution cost of a logistic coalition is generally between 9% and 30% lower than the sum of costs of each partner distributing separately. However, the coalition gain is highly...

Theoretical and methodological bases of threats. The method of security management support

Galanc, Tadeusz; Kolwzan, Wiktor; Pieronek, Jerzy - In: Operations Research and Decisions 3 (2014), pp. 5-21

This paper presents a new formulation of (approach to) threat analysis and management of security understood in a wide sense. Threats have been analyzed in a wide theoretical-methodological spectrum. Particular emphasis is put on the need for the system-wide analysis of threats, especially...
