一种求解逆连续设施定位问题的行生成方法

A row generation method for inverse continuous facility location problem

Jafar Fathali

摘要:

在单个设施定位问题中,给定一组点,目标是找到新设施的最佳位置,相对于给定的标准,如最小化时间,成本和客户与设施之间的距离。另一方面,逆模型试图以最小成本修改问题的参数,使得给定点变得最优。针对一般情况下的平面内变权单设施定位问题,提出了一种新的求解算法。给出了算法的收敛性和最优性条件。在特殊情况下,考虑了逆极小和极小极大单设施定位问题,并对算法进行了实例验证。实验结果表明了该算法在这些实例上的有效性。

英文摘要:

In a single facility location problem, a set of points is given and the goal is finding the optimal location of new facility respect to given criteria such as minimizing time, cost and distances between the clients and facilities. On the other side, the inverse models try to modify the parameters of the problem with the minimum cost such that a given point becomes optimal. In this paper, we introduce a novel algorithm for the general case of the inverse single facility location problem with variable weights in the plane. The convergence and optimality conditions of the algorithm are presented. Then in the special cases, the inverse minisum and minimax single facility location problems are considered and the algorithm tested on some instances. The results indicate the efficiency of the algorithm on these instances.
