WebThe fixed-charge network problem modifies the minimum-cost network flow paradigm of Chapter 9 by adding a term ƒ ƒ i j y i j to the cost, where the binary variable y i j is set to 1 if arc ( i, j) carries a nonzero flow x i j it is set to zero otherwise. In other words, there is a fixed overhead cost for using the arc at all. WebSome of the most interesting and useful applications of integer programming involve 01 variables.

The constraint: “x. j ≤ 10 wj ” isn’t correct because x1 is permitted to be greater than 10 in the fixed charge problem. On the other hand, the constraint “xj ≤ 1000 wj ” is correct. However, larger coefficients can make problems harder to solve.

WebFIXED CHARGE PROBLEMS arise in many "integer" and "nonlin-ear" programming applications. Many of these problems are network problems with fixed charges attached to subsets of the arcs. Examples include the well-known network expansion problems, plant location prob-lems, process selection problems, plus a wide variety of related investment Web1. If x is feasible for the fixed charge problem, then (x, w) is feasible for the IP (w is defined on the last slide) , and the cost in the IP matches the cost of the fixed charge problem. …
