NettetThe problem of solving a system of linear inequalities dates back at least as far as Fourier, who in 1827 published a method for solving them, and after whom the method … Nettettilinear distances are assumed. In addition to linear program ming formulations, search procedures are developed based on the special structure of the location problems examined. JL he problem of locating facilities on the basis of transportation costs has been previously formulated as both a minisum problem (minimize
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… Nettetmixed integer linear program: only some of the variables are integer 0-1 (Boolean) linear program: variables take values 0or 1 Integer linear programming 18–2. Example: facility location problem • npotential facility locations, mclients • ci: cost of opening a facility at location i • dij: cost of serving client ifrom location j Boolean ...
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. Thus, the practitioner is now able … http://seas.ucla.edu/~vandenbe/ee236a/lectures/ilp.pdf
