Show transcribed image text Formulate a mixed integer linear programming problem to optimally locate distribution centers and optimally assign the retailers to the located (or opened) distribution centers. In particular, include constraints to explicitly model the following requirements: bullet Assume single sourcing assignments for the retailers bullet Retailers 1 should not be assigned to DC2 due to contract requirements bullet The transportation loss on an average from the DCs are as follows. bullet Assume the following data for the solving the problem.
