The supervisor of a manufacturing plant is trying to determine how many of two parts, Part X and Part Y, are to be produced per day. Each part must be processed in three sections of the plant. The time required for the production along with the profit contribution for each part are given in the following table. Time Required (Minutes/Unit) Part X Part Y Available time (minutes) Section 1 Section 2 Section 3 50 18 30 0 80 3,600 45 2,500 22 1,200 Profit/Unit $2 $3 No more than 60 units of Part X and up to 70 units of Part Y can be produced daily. The company already has orders for 30 units of Part Y that must be satisfied. Develop an LP model and solve for the optimal production quantities. Obtain the sensitivity report to answer the following questions. a. What is the amount of change in the objective function value if we increase the production quantity of Part Y by 1 unit from the optimal solution? (provide your answer in numerical value only) b. If more time could be made available in Section 2, how much would the profit increase? (provide your answer in numerical value only) c. If we increase the available hours for Section 1 by 100 units, what would be the resulting change in profit? (provide your answer in numerical value only)

Manufacturing Company uses FIFO method of accumulating costs in a two-department process. Materials are introduced at the inception of the process except for a special material which is added in department 2 at 60% completion as to overhead. Inspection is done at the end of the process in both departments. Production data for Department 2 are given below: In process, beginning, (80% labor, 70% overhead)2,000 Transferred in 14,900 In process, ending (40% labor, 20% overhead) 3,000 Normal spoilage 200 Abnormal spoilage (found at 30% completion as to laborand 15% as to overhead due to internal failure) 400 Cost data for the month:In process beginning:Transferred in 15,020 Special materials 1,900 Direct labor 4,388 Overhead 11,044 Current costs:Transferred in 137,080 Special materials 14,030 Direct labor 46,000 Overhead 113,564 The cost of units transferred to finished goods is?The cost of spoilage charged to revenue is?
