Integer linear programming formulation

NettetEverything else is like a standard linear programming problem. I is the set of components of x that must take on integer values. If I is empty, then the integer programming problem is a linear programming problem. If I is not empty but does not include all of {1,...,n}, then sometimes the problem is called a mixed integer programming problem. NettetIn order to formulate this problem as a linear program, we rst choose the decision variables. Let x ij(i= 1;2 and j= 1;2;3) be the number of widgets (in thousands) transported from factory Fito city Cj. Given these x ij’s, we can express the total shipping cost, i.e. the objective function to be minimized, by 5x 11+ 5x 12+ 3x 13+ 6x 21+ 4x 22+ x
