Linear programming facility location problem

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… NettetThe efficient design/redesign of the logistics network is essential for companies to maintain their competitive ad- vantage.
