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.

2-The process of making hotdogs involves six activities: “grind”, “mix”, “stuff”, “cook”, “peel”, and “inspect”. If the capacity of activity “cook” determines the process capacity, which of the following statements are true? a- Activity “cook” is a bottleneck activity. b- The activity time of all the other five activities is shorter than activity "cook". c- Cycle time of the process of making hotdogs is equal=1/capacity of activity “cook”. d- Increasing the capacity of activity “grind” can increase the capacity of the process of making hotdogs. All statements are correct Only statement 'b' is correct Only statements 'a' and 'b' are correct Only statements 'a', 'b' and 'c' are correct Only statement 'a' is correct Only statement 'd' is correct
XYZ makes two types of products using 4 machines for 8 hours each day. Product A visits machines 1, 2 and 4. Product B visits machines 1 and 3. The capacity is 0.6 unit per minute at machine 1. 0.12 unit per minute at machine 2. 0.2 unit per minute at machine 3, and 0.5 unit per minute at machine 4. The demand per dav is 40 units for product A and 160 units per day for product B. Determine the implied utilization (IU) of all resources. What is the bottleneck ? Why ?. Show all formulas used, calculations and results.
Vikiki Furniture, Inc. produces all types of office furniture. The "Executive Secretary" is a sofa-bed that has been designed using ergonomics to provide comfort during long work hours. The sofa-bed sells for $138. There are 580 minutes available during the day, and the average daily demand has been 65 items.

Pieces Moved between Work Areas Each Day lt costs $2 to move I workpiece I foot.What is the cost?
[#2.1] The setup from quiz 1 questions 4 & 5 is repeated below: "Consider software projects flowing through three main activities: requirement planning, development, and testing/implementation. Three different types of resource-types (employees) are needed at each step: analysts for requirement planning; programmers for code development and testers for system testing. There are 2 analysts, 1 developer, and 3 testers. Software projects arrive at the rate of 4 per month (30 days). A project typically takes 10 days for requirement planning, 6 days for code development, and 16 days for testing/implementation. What is the process capacity in projects per month? (show all work). [2.1-2.2] Continuing from the previous question, suppose user-training work is a new activity that must be carried out on each project. It is supposed to take 2 days for each project. Which of the three resource-types should perform this activity and what is the new process capacity? " Based only on the above…
1. A process is accomplished in 4 sequential steps- S1, S2, S3 and S4. The lead times (in minutes) and the number of resources for every step are indicated in the table below.

If this production line has three workstations and a cycle time of 1.5 minutes , what is its efficiency ?
A manager must decide which type of machine to buy, A, B, or C. Machines costs are as follows: Machine Cost A $40,000 B $30,000 C $80,000 Product forecast, processing times on the machines, and setup times are as follows: Processing Time Per Unit (minutes) Product Annual Demand A B C Setup Times (minutes) Production Lots (units) 1 16,000 3 4 2 20 200 2 12,000 4 5 3 35 100 3 6,000 5 6 3 60 50 4 30,000 2 4 1 15 500 Machines operate 10 hours a day, 250 days a year. The manager wants to have a capacity cushion of 10%. a. Assume that only purchasing costs are being considered. Which machines would have the lowest total cost, and how many of that machines would be needed? b. Consider this additional information: The machines differ in terms of hourly operating costs: The A machines have an hourly operating cost of $11 each, B machines have an hourly operating cost of $10 each, and C machines have an hourly operating cost of $12 each.
