Aggregation of Hospital Business Processes
Meier, Markus; Rosenkranz, Friedrich - 2011
There are estimates that up to 30% of hospital costs are due to inefficiently coordinated hospital processes. As a result many hospitals have tried to model and to reengineer their business processes. These efforts have very often been abandoned, because the normally constructed total models of...

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,...

Impact of the CAP reform on small-scale grassland regions
Roeder, Norbert; Kantelhardt, Jochen; Kapfer, Martin - In: Agrarwirtschaft: Zeitschrift für Betriebswirtschaft, … 55 (2006) 5/6, pp. 257-267
This paper presents a regional land-use model that conceives farms as independent agents aiming at maximum individual utility. Farm agents optimize their utility with the help of a linear-programming algorithm that takes into account natural, economic and personal restrictions. Interactions...

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...

Standard and Shuffled Halton Sequences in a Mixed Logit Model
Staus, Alexander - 2008
. Simulation methods have been developed to approximate a solution for these integrals. This paper describes the Standard Halton … sequence and a modification of it, the Shuffled Halton sequence. Both are simulation methods which can reduce computational … effort compared to a random sequence. We compare the simulation methods in their coverage of the multi-dimensional area and …

Firms formation and growth in the model with heterogeneous agents and monitoring
Marko, Peter; Švarc, Petr - 2008
In this article we extend the agent-based model of firms' formation and growth proposed in [4]. In [4] the firms' creation, expansion or contraction results from the interaction of heterogeneous utility maximizers. While the original model was able to replicate the power law distribution in the...
