Multi-Factor Policy Evaluation and Selection in the One-Sample Situation

Chen, Chen, C.M. - Erasmus Research Institute of Management (ERIM), … - 2008

Firms nowadays need to make decisions with fast information obsolesce. In this paper I deal with one class of decision problems in this situation, called the “one-sample” problems: we have finite options and one sample of the multiple criteria with which we use to evaluate those options. I...

Rostering at a Dutch Security Firm

Freling, Freling, R.; Piersma, N.; Wagelmans, … - Erasmus Research Institute of Management (ERIM), … - 2001

The roster planning process at the Dutch security firm NVD was traditionally carried out by hand. A few years NVD was traditionally carried out by hand. A few years ago, because of changing labor laws in the Netherlands, this became practically impossible. We developed a decision support system...

On the Suboptimality of Full Turnover-Based Storage

Yu, Yu, Y.; de Koster, de Koster, M.B.M. - Erasmus Research Institute of Management (ERIM), … - 2009

resulting average storage and retrieval machine travel time. In practice however, ABC storage is the dominant policy. Hausman et … level. This paper adapts the travel time model of Hausman et al. to accommodate full turnover-based dedicated storage …. Surprisingly, the result of the adapted travel time model is opposite to that of Hausman et al. (1976) but, in line with practice …

On Noncooperative Games and Minimax Theory

Frenk, Frenk, J.B.G.; Kassay, G. - Erasmus Research Institute of Management (ERIM), … - 2005

In this note we review some known minimax theorems with applications in game theory and show that these results form an equivalent chain which includes the strong separation result in finite dimensional spaces between two disjoint closed convex sets of which one is compact. By simplifying the...

Dataset of the Refrigerator Case: design of closed loop supply chains

Bloemhof-Ruwaard, Jacqueline Bloemhof; Krikke, Krikke, H.R. - Erasmus Research Institute of Management (ERIM), … - 2001

This paper contains the dataset for the refrigerator case concerning the design of a production and return network for refrigerators. Section 1 emphasises the major changes to the problem structure and assumptions used by Umeda et al. (1999). Section 2 contains the parameter settings. Section 3...

Pattern-Based Target Selection Applied to Fund Raising

Kaymak, Uzay; Pijls, Pijls, W.H.L.M.; Potharst, Potharst, R. - Erasmus Research Institute of Management (ERIM), … - 2001

This paper proposes a new algorithm for target selection. This algorithm collects all frequent patterns (equivalent to frequent item sets) in a training set. These patterns are stored e?ciently using a compact data structure called a trie. For each pattern the relative frequency of the target...

Operations Research in Passenger Railway Transportation

Huisman, Dennis; Kroon, Kroon, L.G.; Lentink, Lentink, R.M. - Erasmus Research Institute of Management (ERIM), … - 2005

In this paper, we give an overview of state-of-the-art Operations Research models and techniques used in passenger railway transportation. For each planning phase (strategic, tactical and operational), we describe the planning problems arising there and discuss some models and algorithms to...

An NPV and AC Analysis of a Stochastic Inventory System with Joint Manufacturing and Remanufacturing

van der Laan, Erwin - Erasmus Research Institute of Management (ERIM), … - 2000

While the net present value (NPV) approach is widely accepted as the right framework for studying production and inventory control systems, average cost (AC) models are more widely used. For the well known EOQ model it can be veri_ed that (under certain conditions) the AC approach gives near...
