NettetIn this lecture, as well as the next two lectures, we will study the uncapacitated facility location problem, using it as a vehicle to illustrate several different techniques that are commonly used to devise approximation algorithms for NP-hard problems. 1 The general Uncapacitated facility location problem Deﬁnition 1.1. Nettet7. feb. 2015 · The Rsymphony package in R can solve this problem for you. You will need a vector of the distances c i, j and 0's for each y i as well as a matrix to take care of the constraints (the three summations starting after "subject to"). If you aren't familiar with the constraint matrix, each column contains the coefficients for that variable.

NettetThis paper investigates the simple uncapacitated plant location problem on a line. We show that under general conditions the special structure of the problem allows the optimal solution to be obtained directly from a linear programming relaxation. This result may be extended to the related p-median problem on a line.

NettetExample 6.3 Facility Location. Consider the classic facility location problem. Given a set of customer locations and a set of candidate facility sites, you must decide on … Facility location problems are often solved as integer programs. In this context, facility location problems are often posed as follows: suppose there are facilities and customers. We wish to choose (1) which of the facilities to open, and (2) which (open) facilities to use to supply the customers, in order to satisfy some fixed demand at minimum cost. We introduce the following notation: let denote the (fixed) cost of opening facility , for . Let denote the cost to ship a product fr…
