Problem 8-12 Alan Industries is expanding its product line to include three new products: A, B, and C. These are to be produced on the same production equipment, and the objective is to meet the demands for the three products using overtime where necessary. The demand forecast for th next four months, in hours required to make each product is: 800 800 600 700 500 800 1,200 1,100 700 Because the products deteriorate rapidly, there is a high loss in quality and, consequently, a high carrying cost when a product is made and carried in inventory to meet future demand Each hour's production carried into future months costs S3 per production hour for A, S4 for Model B, and $5 for Model C. Production can take place either during regular working hours or during overtime. Regular time is paid at $4 when working on A, S5 for B, and $6 for C. The overtime premium is 50 percent of the regular time cost per hour The number of production hours available for regular time and overtime is 2,000 1,000 Regular time 1,500 700 1,300 650 1,800 900 Calculate the objective value using Excel Solver Objective value
