The M-N plant manufactures two different products: M and N. Selling prices and weekly market demands are shown in the following diagram. Each product uses raw materials with costs as shown. The plant has three different machines: A, B, and C. Each performs different tasks and can work on only one unit of material at a time. Resources: A, B, C (one each) Availability: 3,500 min./week Operating expense: $12,000/week Product M Product N $190/unit 100 units/week $200/unit 80 units/week C 15 min./unit C 15 min./unit A B B 20 min./unit 5 min./unit 5 min./unit RM-1 $60/unit RM-2 $40/unit RM-3 $55/unit Process times for each task are shown in the diagram. Each machine is available 3,500 minutes per week. There are no "Murphys" (major opportunities for the system to foul up). Setup and transfer times are zero. Demand is constant. Operating expenses (including labor) total a constant $12,000 per week. Raw materials are not included in weekly operating expenses.

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?

Tailwind, Inc., produces high-quality but expensive training shoes for runners. The Tailwindshoe, which sells for $210, contains both gas- and liquid-filled compartments to provide morestability and better protection against knee, foot, and back injuries. Manufacturing the shoesrequires 10 separate tasks. There are 400 minutes available for manufacturing the shoes inthe plant each day. Daily demand is 60. The information for the tasks is as follows: Task Performance Time (In minutes) Task Must Follow This task A 1 ___ B 3 A C 2 B D 4 B E 1 C.D F 3 A G 2 F H 5 G I 1 E,H J 3/25 I 1. What is the theoretical minimum number of work stations required to satisfy this output rate? 2. Allocate the tasks to work stations taking into consideration the precedence requirements and usingthe LOT rule to break ties between feasible tasks.
