Mixed integer model fixed charge problem
WebWe apply to fixed charge network flow (FCNF) problems a general hybrid solution method that combines constraint programming and linear programming. FCNF problems test the … Web11 nov. 2024 · 1 Answer Sorted by: 2 It's very likely you're running into numerical precision issues. Check point 2 of this part of the pulp docs. You're using too many decimal numbers for your floats in the parameters of the constraints and objective function coefficients. Just round all parameters to 2 or 3 decimals (or whatever makes sense for your problem).

Management Science 49(9):1268-1273. Webproblem (see, e.g., [4,5]). One strand of the literature on cutting planes is concerned with MILPs that involve xed charges (see, e.g., [1,9{11,14,16{18,21{24,26]). A xed charge is an additional cost that is incurred whenever a certain variable takes a positive value. The textbook way to model xed charges is as follows. Suppose that x
