State the types of data that would be carried in the bill-of-materials file and the inventory record file.
Develop a production plan and calculate the annual cost for a firm whose demand forecast is fall, 10,000; winter, 8,000; spring, 7,000; summer, 12,000. Inventory at the beginning of fall is 500 units. At the beginning of fall, you currently have 30 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 stock-outs at the end of those quarters. Overtime is not available during the fall. Relevant costs are hiring, \(100 for each temp; layoff, \)200 for each worker laid off; inventory holding, \(5 per unit-quarter; backorder, \)10 per unit; straight time, \(5 per hour; over time, \)8 per hour. Assume that the productivity is 0.5 units per worker hour, with eight hours per day and 60 days per season.
