Price Competition on Graphs
Soetevent, Adriaan R. - 2010
This paper extends Hotelling's model of price competition with quadratic transportation costs from a line to graphs. I …'Aspremont et al. (1979) does not extend to simple star graphs and I conjecture thatthis non-existence result holds more generally …

Constructing fair sports leagues schedules
Briskorn, Dirk; Knust, Sigrid - 2008
A single round robin tournament (SRRT) consists of n teams and a set of periods. Matches between the teams have to be scheduled such that each team plays against each other team exactly once and each team plays at most once per period. In order to establish fairness among teams we consider a...

Sales force deployment by genetic concepts
Sprecher, Arno - 1999
Sales force management decisions belong to the major issues considered in marketing research. Among others, the alignment of sales territories has been one of the main field of work for years. Recent results have reported a strong impact of the alignment of sales territories on profit, and,...

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...

Stochastic mixed model sequencing with multiple stations using reinforcement learning and probability quantiles
Brammer, Janis; Lutz, Bernhard; Neumann, Dirk - In: OR Spectrum 44 (2021) 1, pp. 29-56
In this study, we propose a reinforcement learning (RL) approach for minimizing the number of work overload situations in the mixed model sequencing (MMS) problem with stochastic processing times. The learning environment simulates stochastic processing times and penalizes work overloads with...

SinkRank: An algorithm for identifying systemically important banks in payment systems
Soramäki, Kimmo; Cook, Samantha - In: Economics: The Open-Access, Open-Assessment E-Journal 7 (2013) 2013-28, pp. 1-27
The ability to accurately estimate the extent to which the failure of a bank disrupts the financial system is very valuable for regulators of the financial system. One important part of the financial system is the interbank payment system. This paper develops a robust measure, SinkRank, that...

A General Solution Framework for Component-Commonality Problems
Boysen, Nils; Scholl, Armin - In: BuR - Business Research 2 (2009) 1, pp. 86-106
Component commonality - the use of the same version of a component across multiple products - is being increasingly considered as a promising way to offer high external variety while retaining low internal variety in operations. However, increasing commonality has both positive and negative cost...
