To specify that production of product 1 in period 3 and in period 4 differs by no more that 100 units. g. X 13 – X 14 < 100; X 14 – X 13 < 100. h. X 13 – X 14 < 100; X 13 – X 14 > 100. i. X 13 – X 14 < 100; X 14 – X 13 > 100. j. X 13 – X 14 > 100; X 14 – X 13 > 100. • There is shadow price for every decision variable in a model a. True b. False • Because the shadow price represents the improvement in the value of the optimal solution per unit increase in right-hand side, a shadow price cannot be negative a. True b. False • Demand constraints frequently take the form: Beginning inventory + production - ending inventory = demand a. True b. False...
