在本文中，我们提出了一种新的方法来估计市场份额的竞争设施。该方法是基于覆盖定位模型。每个竞争设施都有一个由其吸引力水平决定的“影响范围”。更有吸引力的设施拥有更大的势力范围半径。在几个设施的影响范围内，客户的购买力在竞争设施之间平均分配。在任何设施的影响范围内，顾客的购买力都不会丧失。假设该地区存在竞争，目标是在现有设施链中增加一些新设施，以最大限度地增加该链所占的市场份额。该模型制定和分析。设计了最优和启发式求解算法。计算实验证明了所提算法的有效性。Journal of the Operational Research Society（2011）62，100-113. doi：10.1057/jors.2009.153在线发布2010年1月6日
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 attractive facilities have a larger radius of the sphere of influence. The buying power of a customer within the sphere of influence of several facilities is equally divided among the competing facilities. The buying power of a customer within the sphere of influence of no facility is lost. Assuming the presence of competition in the area, the objective is to add a number of new facilities to a chain of existing facilities in such a way that the increase of market share captured by the chain is maximized. The model is formulated and analysed. Optimal and heuristic solution algorithms are designed. Computational experiments demonstrate the effectiveness of the proposed algorithms.
