灾后企业选址问题的模型研究

建立了灾后企业选址的一种决策模型。对遭受自然或人为灾害打击中，不得不进行迁移的企业，如何实施有效的选址决策进行了研究，在给定假设的基础上，构造了一个非线性规划问题，提出了进行区位决策的迭代算法，并对如何解决已有多个企业及顾客有偏好的复杂情况进行了讨论，研究表明，在以市场竞争为导向的动态选址过程中，企业从最大程度地占有市场的目标出发，倾向于定位在一个特定的市场吸引点上。

MODEL OF LOCATION FOR POST-DISASTER FIRMS

The paper presents a new model of location to support the decision making of a post disaster firm in the market, which is supposed to gain the most possible market share in competition with an existing firm. Based on 4 assumptions, a nonlinear programme is set up and a solution to this programme is put forward. The paper also discusses the modifying of the model to solve the problem when there exist more than one old firm and/or the customers have different preferences for different firms. The paper manifests that firms are prone to locate at an attractive point to share the market equally in the end of the dynamic process of location. The model could help post disaster firms to find the best location to gain the largest market share.
