Drezner, T., Auteur ; Z. Drezner, Auteur ; Kalczynski, P., Auteur |In this paper we propose a new approach to estimating market share captured by competing facilities. The approach is based on cover location models. Each competing facility has a ‘sphere of influence’ determined by its attractiveness level. More[...]

O. Berman, Auteur ; Z. Drezner, Auteur ; D. Krass, Auteur |A family of discrete cooperative covering problems is analysed in this paper. Each facility emits a signal that decays by the distance and each demand point observes the total signal emitted by all facilities. A demand point is covered if its cu[...]

Z. Drezner, Auteur ; S. Nickel, Auteur ; H.-P. Ziegler, Auteur |Many location problems can be expressed as ordered median objective. In this paper, we investigate the ordered median objective when the demand points are generated in a circle. We find the mean and variance of the kth distance from the centre o[...]

Drezner, T., Auteur ; Z. Drezner, Auteur ; Kalczynski, P., Auteur |Competitive facility location models consider two main strategies for increasing the market share captured by a chain subject to a budget constraint. One strategy is the improvement of existing facilities. The second strategy is the construction[...]
