Describe the advantages and limitations of the transportation method for aggregate planning.

A firm's demand in the next four quarters (its aggregate planning horizon) is forecast to be 80,50,40,and 90 units.Last quarter,the firm produced 60 units.If it uses level scheduling,the firm will

Houma Containers,Inc. ,makes industrial fibreglass tanks that are used on offshore oil platforms.Demand for the next four months and capacities of the plant are shown in the table below.Unit cost on regular time is $400.Overtime cost is 150% of regular time cost.Subcontracting is available in substantial quantity but at a very high cost,$1100 per unit.Holding costs are $200 per tank per month;back orders cost the firm $1000 per unit per month.Houma's management believes that the transportation algorithm can be used to optimize this scheduling problem.The firm has no beginning inventory and anticipates no ending inventory. a.How many units will be produced on regular time in June? b.How many units will be produced by subcontracting over the four-month period? c.What will be the inventory at the end of April? d.What will be total production from all sources in April? e.What will be the total cost of the optimum solution? f.Does the firm utilize the expensive options of subcontracting and back ordering? When;why?

________ involves capacity decisions that determine the allocation of classes of resources in order to maximize profit or yield.

Osprey Machine Works has the following demand requirements and other data for the upcoming four quarters. What is the total cost of pursuing a level aggregate plan over the coming year?

Which of the following is not one of the four things needed for aggregate planning?

An electronics manufacturer makes video security systems for parking lots.Demand estimates for the next four quarters are 15,9,23,and 17 units.Prepare an aggregate plan that uses inventory,regular time,overtime,and back orders.Subcontracting is not allowed.Regular time capacity is 12 units for quarters 1 and 2,15 units for quarters 3 and 4.Overtime capacity is 6 units per quarter.Regular time cost is $20,000 per system,while overtime cost is $30,000 per unit.Back order cost is $2000 per system per quarter;inventory holding cost is $500 per unit per quarter.Beginning inventory is zero. Complete the table of data inputs for solving this aggregate planning problem with the transportation method.Specifically,how many sources are there,and how many destinations? What is the supply from each source,and the demand of each destination? What is the cost of each source-destination pair?
