Question 2: A manager would like to know the minimum total cost of the aggregate planning for the next four quarters based on the following information: - Each worker can produce 7 units per day. the number of workers available at the beginning of the period one is 10 . - The demand and the number of business days for each period are presented in the following table: - Beginning inventory is 500 units and planned ending inventory is 1500 units. - The cost per unit produced in regular time is $15. - The cost per unit produced in overtime is $18. - The cost per unit produced by subcontracted workers is $20. - The cost per unit on average inventory is $3 per period. - The cost per unit per period on back orders is $23 - The cost to hire a worker is $700, and the cost to lay off a worker is $1000 Instructions: a. Develop an aggregate plan using level output strategy. (10 points) a. Develop an aggregate plan using pure chase demand strategy. (10 points) b. Set up the mathematical model for the planning horizon. (10 points) c. Suppose you need to combine hiring, overtime and subcontract. - What is the minimum number of units that must be missing to consider to hire a worker instead of having production in overtime?
