WebThe Reliability Fixed-Charge Location Problem is an extension of the Simple Plant Location Problem that considers that some facilities have a probability of failure. In this paper we reformulate the original mathematical programming model of the Reliability Fixed-Charge Location Problem as a set packing problem. 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.
