Given the following information set up the problem in a transportation table and solve for the minimum cost plan PERIOD 2 700 Demand Capacity Regular Overtime Subcontract Beginning inventory Costs Regular time Overtime Subcontract Inventory carrying cost Back order cost 550 500 50 120 100 60 per unit 80 per unit 90 per unit 500 50 120 1 per unit per month 3 per unit per month 3 750 440 50 100 Suppose the inventory carrying cost has just increased and is now 2 per unit per period Compute the total cost for the original transportation model with 1 inventory carrying cost and the new total cost at 2 carrying cost What is the additional cost for the optimal plan
