设施选址中的不等式约束及其它类似最优化问题:基于熵的方法

Inequality Constraints in Facility Location and Other Similar Optimization Problems: An Entropy Based Approach

Amber Srivastava, Gabriel Barsi Haberfeld, Naira Hovakimyan, Srinivasa M Salapaka

摘要:

在本文中,我们提出了一个基于退火的框架,将不等式约束的最优化问题,如设施的位置,同时设施的位置与路径优化,和最后一英里的交付问题。这些不等式约束用于对相应设施、运输路径和服务车辆上的若干应用特定尺寸和容量限制进行建模。我们设计我们的算法的方式,它允许(可能)违反的约束条件在算法的初始阶段,以便于彻底探索的解决方案空间;随着算法的进行,这种违反(通过退火参数控制)逐渐降低,直到解决方案收敛在可行域的最优化问题。我们在各种数据集上进行了模拟,证明了我们算法的有效性。

英文摘要:

In this paper we propose an annealing based framework to incorporate inequality constraints in optimization problems such as facility location, simultaneous facility location with path optimization, and the last mile delivery problem. These inequality constraints are used to model several application specific size and capacity limitations on the corresponding facilities, transportation paths and the service vehicles. We design our algorithms in such a way that it allows to (possibly) violate the constraints during the initial stages of the algorithm, so as to facilitate a thorough exploration of the solution space; as the algorithm proceeds, this violation (controlled through the annealing parameter) is gradually lowered till the solution converges in the feasible region of the optimization problem. We present simulations on various datasets that demonstrate the efficacy of our algorithm.
