Thank you for letting me know, sorry for the missing info! :)
A Juarez, Mexico, manufacturer of roofing supplies has developed monthly forecasts for a family of products. Data for the 6-month period January to June are presented in the table below. There are 8 hours of production per day. a) The firm would like to begin development of an aggregate plan. For this plan, plan 5 , the firm wishes to maintain a constant workforce of 6 , using subcontracting to meet remaining demand. Evaluate this plan. To determine whether this plan is desirable, first calculate demand per day for each month (enter your responses rounded to the nearest whole number). Her operations manager is considering a new plan, which begins in January with 200 units of inventory on hand. Stockout cost of lost sales is $125 per unit. Inventory holding cost is $20 per unit per month. Ignore any idle-time costs. The plan is called plan A. Plan A: Vary the workforce level to execute a strategy that produces the quantity demanded in the prior month. The December demand and rate of are both 1,600 units per month. The cost of hiring additional workers is $50 per unit. The cost of laying off workers is $75 per unit. Evaluate this plan. (Enter all responses as whole numbers.) Note: Both hiring and layoff costs are incurred in the month of the change. For example, going from 1,600 in January to 1,200 in February incurs a cost of layoff for 400 units in February. Her operations manager is considering a new plan, which begins in January with 200 units of inventory on hand. Stockout cost of lost sales is $65 per unit. Inventory holding cost is $25 per unit per month. Ignore any idle-time costs. Evaluate the following plans D and E. Plan D: Keep the current workforce stable at producing 1,600 units per month. In addition to the regular production, another 20% of the normal production units can be produced in overtime at an additional cost of $50 per unit. A warehouse now constrains the maximum allowable inventory on hand to 600 units or less. Note: Do not produce in overtime if production or inventory are adequate to cover demand. Consuelo Chua, Inc., is a disk drive manufacturer in need of an aggregate plan for July through December. The company has gathered the following data given in the tables. There are 8 hours of production per day. You manage a consulting firm down the street from Consuelo Chua, Inc., and to get your foot in the door, you have told Mr. Chua that you can do a better job at aggregate planning than his current staff. He said, "Fine. You do that, and you have a 1-year contract." To make good on your boast, you propose a new strategy. Hire 5 workers in August and 5 more in October, and subcontract to meet the rest of the demand. What will be the cost of this strategy? Fill in the table below. (Enter all responses as whole numbers. In the hire/fire column, use positive numbers for hires -- plus signs omitted; negative numbers for layoffs.)
