近年来，随着养老问题的日益严重，养老院建设成为一项重要项目。同时，在疗养院建设前确定疗养院的选址对于决策者来说至关重要。有效的区位规划可以实现资源合理配置和社会公平。本文考虑了具有两个目标的疗养院选址和分配问题。第一个目标是尽量减少总建设成本，这是从政府的角度考虑的。对于老年人来说，他们的期望是分配给他们的疗养院距离他们孩子的社区足够近。因此，第二个目标是最小化总距离。建立了双目标混合整数规划（MIP）模型，并采用精确的ε约束方法来获得一组最优Pareto解。进行案例研究并进行比较。获得的结果表明所提出的模型和采用的方法适用于现实世界的疗养院选址和分配问题。
In recent years, along with the more and more serious pension issues, nursing home construction becomes an important project. Meanwhile, it is crucial for decision makers to determine the location of a nursing home before its construction. An effective location planning could achieve reasonable resources allocation and social fairness. This paper considers a nursing home location and allocation problem with two objectives. The first objective is to minimize the total construction costs, which is considered from the perspective of the government. For the elderly people, their expectations are their allocated nursing homes close enough to their children's communities. Therefore, the second objective is to minimize the total distances. A bi-objective mixed-integer programming(MIP) model is formulated and an exact ε-constraint method is adopted to obtain a set of optimal Pareto solutions. A case study is conducted with comparisons. The obtained results demonstrate the proposed model and adopted method are suitable for the real-world nursing home location and allocation problem.
