摘要: 新建物流配送中心在选址时不仅要考虑到与已有配送中心的竞争,还要预测到未来可能出现的竞争者,否则将会在竞争中处于劣势地位. 因此建立了“原有配送中心—新建配送中心—未来加入配送中心”这一框架下的双层规划模型,为竞争环境下的新建配送中心选址提供决策依据. 上层目标极大化新建配送中心在计划期内的市场份额,下层目标极大化未来竞争者的市场份额. 其中市场份额由配送中心与需求者之间的距离作为可观察项的多项logit模型来刻画. 设计了遗传算法求解,最后通过实例验证该模型与算法可以有效的避免损失,提高新建配送中心的竞争力.

Abstract: The decision-maker not only considers the competition with the existing logistics distribution centers but also predicts the future latent competitor when locating a new one, or else he will be inferior. A bi-level programming model on location for the decision-maker is modeled based on the frame of “the existing distribution centers-a new distribution center-a future competitor”. The objective of the upper model is to maximize the new distribution center’s market share in a given horizon, and the lower model is to maximize the future competitor’s. The market share is depicted by multinomial logit model whose observable item is the distance between the distribution center and the demander. A genetic algorithm is designed. At last an example illustrates the effectiveness of the model and the solution.
