Problem 1: suppose Southern Mechanics has different demand forecast as follows:

Please develop aggregate plan

Forecast 1 12 13 14 15 16 Total 14 |150|200 350 400 500/200|1,800 The current cost composition is as follows: Output Regular time = $2 per skateboard Overtime = $3 per skateboard Subcontract = $6 per skateboard Inventory = $1 per skateboard per month on average inventory Back orders = $5 per skateboard per month Southern Mechanics has capacity of outputing 300 skateboards per month . And the over time capacity is 80 and subcontracting capacity is 90. The initial inventory is zero and should have an ending inventory of zero in the last month. When solving every subproblem, please use the conditions described above and in the subproblem. Do not use conditions described in other subproblems. All solutions for the subproblems should be filled in the blank form given in Solution section. (if your choice is zero, please do not fill it in the form and just left blank): Problem2: MRP Southern Mechanics may make different master production schedules: MPS 4 Al 8th week | 400 12' week 400 Forecast 1 12 13 14 15 16 Total 14 |150|200 350 400 500/200|1,800 The current cost composition is as follows: Output Regular time = $2 per skateboard Overtime = $3 per skateboard Subcontract = $6 per skateboard Inventory = $1 per skateboard per month on average inventory Back orders = $5 per skateboard per month Southern Mechanics has capacity of outputing 300 skateboards per month .
