Do the empty and incorrect ones for the 3 questions

Develop a production plan and calculate the annual cost for a firm whose demand forecast is fall, 10,500 ; winter, 8,000; spring, 7,000; summer, 12,500. Inventory at the beginning of fall is 525 units. At the beginning of fall, you have 35 workers, but you plan to hire temporary workers at the beginning of summer and lay them off at the end of summer. In addition, you have negotiated with the union an option to use the regular workforce on overtime during winter or spring if overtime is necessary to prevent backorders at the end of those quarters. Overtime is not available during the fall. Relevant costs are hiring, $1,000 for each temp; layoff, $2,000 for each worker laid off; inventory holding, $5 per unitquarter; backorder, \$10 per unit; straight time, \$25 per hour; overtime, \$35 per hour. Assume that the productivity is 0.5 unit per worker hour, with eight hours per day and 60 days per season. In each quarter, produce to the full output of your regular workforce, even if that results in excess production. In winter and spring, use overtime only if needed to meet the production required in that quarter. Do not use overtime to build excess inventory in prior seasons expressly for the purpose of reducing the number of temp workers in Summer. Note: Leave no cells blank - be certain to enter " 0 " wherever required. Negative values should be indicated by a minus sign. Round up "Number of temp workers, Workers hired, and Workers laid off" to the next whole number and all other answers to the nearest whole number. Develop a production schedule to produce the exact production requirements by varying the workforce size for the following problem. Evaluate the cost of production schedule. The monthly forecasts for the product X for January, February, and March are 930,1,550, and 1,220, respectively. Safety stock policy recommends that half of the forecast for that month be defined as safety stock. There are 22 working days in January, 19 in February, and 21 in March. Beginning inventory is 550 units. Manufacturing cost is $2,800 per unit, storage cost is $6 per unit per month (based on expected end-ofmonth levels, standard pay rate is $12 per hour, hiring and training cost is $2,800 per worker, layoff cost is $3,800 per worker, and worker productivity is 0.1 unit per hour. Assume that you start off with 47 workers and that they work 8 hours per day. Note: Leave no cells blank - be certain to enter " 0 " wherever required. Input all values as positive values. Round Workers Required up to next higher whole number. Round all other variables to nearest whole number. Helter Industries, a company that produces a line of bathing suits, hires temporary workers to help produce its summer product demand. For the current four-month rolling schedule, there are three temps on staff and 12 full-time employees. The temps can be hired when needed and can be used as needed, whereas the full-time employees must be paid whether they are needed or not. Each full-time employee can produce 195 suits, while each temporary employee can produce 155 suits per month. Demand for bathing suits for the next four months is: Beginning inventory in May is 402 complete (a complete two-piece includes both top and bottom) bathing suits. Bathing suits cost $40 to produce and carrying cost is 48 percent per year. Develop an aggregate plan that uses the 12 full-time employees each month and a minimum number of temporary employees. Assume that all employees will produce at their full potential each month. Calculate the inventory carrying cost associated with your plan using planned end-of-month levels. Note: Round "Inventory cost" to 2 decimal places
