Why Are Some Entrepreneurs More Innovative Than Others?

Koellinger, Philipp - Erasmus Research Institute of Management (ERIM), … - 2007

The study provides theoretical insights and empirical evidence on the emergence of different types and degrees of entrepreneurial innovativeness. The results suggest that entrepreneurial innovativeness depends both on individual factors and on the environment in which the individual lives. In...

Attractive Supervisors: How Does the Gender of the Supervisor Influence the Performance of the Supervisees?

Koellinger, Philipp; Block, Joern H. - Erasmus Research Institute of Management (ERIM), … - 2012

A series of field and laboratory experiments were conducted in which single-sex groups of male or female students competed in different intellectual tasks to earn money or university grades (N = 291). The supervisor of these groups was one of several young and attractive males or females. The...

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...

Effective algorithms for integrated scheduling of handling equipment at automated container terminals

Meersmans, P.J.M.; Wagelmans, Wagelmans, A.P.M. - Erasmus Research Institute of Management (ERIM), … - 2001

In this paper we consider the problem of integrated scheduling of various types of handling equipment at an automated container terminal, where the objective is to minimize the makespan of the schedule. We present a Branch & Bound algorithm that uses various combinatorial lower bounds....

Optimal Redesign of the Dutch Road Network

Snelder, M.; Wagelmans, Wagelmans, A.P.M.; Schrijver, J.M. - Erasmus Research Institute of Management (ERIM), … - 2005

The Dutch national road network has been developed over several decades. In the past, roads were constructed according to the then current spatial and transportation planning philosophies. Because the existing road network is a result of a long process of successive developments, the question...

Applying an Integrated Approach to Vehicle and Crew Scheduling in Practice

Huisman, Dennis; Freling, Freling, R.; Wagelmans, … - Erasmus Research Institute of Management (ERIM), … - 2000

This paper deals with a practical application of an integrated approach to vehicle and crew scheduling, that we have developed previously. Computational results have shown that our approach can be applied to problems of practical size. However, application of the approach to the actual problems...

A decision support system for crew planning in passenger transportation using a flexible branch-and-price algorithm

Freling, Freling, R.; Lentink, Lentink, R.M.; … - Erasmus Research Institute of Management (ERIM), … - 2001

This paper discusses a decision support system for airline and railway crew planning. The system is a state-of-the-art branch-and-price solver that is used for crew scheduling and crew rostering. We briefly discuss the mathematical background of the solver, of which most part is covered in the...

A Note on Ending Inventory Valuation in Multiperiod Production Scheduling

van den Heuvel, Wilco; Wagelmans, Wagelmans, A.P.M. - Erasmus Research Institute of Management (ERIM), … - 2002

In a recent paper, Fisher et al. (2001) present a method to mitigate end-effects in lot sizing byincluding a valuation term for end-of-horizon inventory in the objective function of the short-horizon model. Computational tests show that the proposed method outperforms the Wagner-Whitin algorithm...

Dynamic Scheduling of Handling Equipment at Automated Container Terminals

Meersmans, P.J.M.; Wagelmans, Wagelmans, A.P.M. - Erasmus Research Institute of Management (ERIM), … - 2001

In this paper we consider the problem of integrated scheduling of various types of handling equipment at an automated container terminal in a dynamic environment. This means that the handling times are not known exactly beforehand and that the order in which the different pieces of equipment...
