Facility Location In this example, we’ll solve a simple facility location problem: where to build warehouses to supply a large number of supermarkets. We’ll construct a mathematical model of the business problem, implement this model in the Gurobi Python interface, and compute and visualize an...

思路一:贪心 容易想到的是,从每个用户的角度出发,要使得总成本最小的话,则可以每个用户选择设施的时候都贪心选择一个成本最低的设施。一开始我想的是所有设施都先不开,然后由每个用户去贪心选择,计算选择一个设施需要的成本,如果设施还没开的话,则要加上开设施的成本,最后选择成本最低的那个。但后来仔细一想,其...
In this paper, we investigate the location of a facility and several transfer points to serve as collector points for customers who need the services of the facility. For example, demand for emergency services is generated at a set of demand points that need the services of a central facility...
Facility location problem is to find locations for new facilities such that the conveying cost from facilities to customers is minimized. Facility location problem has been studied for half a century because of its widely practical application backgrounds.In practice, some factors such as demands, all...
Capacitated Facility Location Problem 题目描述 Suppose there are n facilities and m customers. We wish to choose: (1) which of the n facilities to open (2) the assignment of customers to facilities The objective is to minimize the sum of the opening cost and the assignment cost....

四种方法求Capacitated Facility Location Problem问题 问题详情 1. 贪心算法 1.1 算法框架 此题可以利用贪心算法来求解, 可以假设只关注顾客的cost, 当仓库满了就在下一个仓库里 具体解决方案: 将每个顾客到工厂的cost 由小到大进行排序 从第一个用户开始, 优先把此用户安排在cost小的工厂里, 如果此工厂容量已...
This paper studies a reliable facility location problem with facility protection that aims to hedge against random facility disruptions by both strategically protecting some facilities and using backup facilities for the demands. An Integer Programming model is proposed for this problem, in which the fai...
