Consider a process consisting of five resources that are operated 8 hours per day. Theprocess works on three different products, A, B, and C: Demand for the three different products is as follows: product A, 40 units per day;product B, 50 units per day; and product C, 60 units per day.a. What is the bottleneck?b. What is the flow rate for each flow unit, assuming that demand must be served in the mixdescribed above (i.e., for every four units of A, there are five units of B and six units of C)?
A TV factory plans to add production lines for its new product and plans to produce as many as 200 units per hour. The production process, production time, and the production process to continue the next production process are described in the table below: (1 day = 8 working hours) Production Process Production Time (s) The production process that follows the next production according to the list below A 12 - B 15 A C 8 A D 5 B,C E 20 D Based on the data above. a. What is the cycle time for the production of the new product? (note: in seconds)b. What is the minimum number of workstations?
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
Bill’s Barbershop has two barbers available to cut customers’hair. Both barbers provide roughly the same experience andskill, but one is just a little bit slower than the other. The pro-cess flow in Figure 5.9 shows that all customers go throughsteps B1 and B2 and then can be served at either of the twobarbers at step B3. The process ends for all customers atstep B4. The numbers in parentheses indicate the minutes ittakes that activity to process a customer. a. How long does it take the average customer to completethis process?b. What single activity is the bottleneck for the entireprocess?c. How many customers can this process serve in an hour?
A TV factory plans to add production lines for its new product and plans to produce as many as 800 units per hour.

What is the cycle time for the production of the new product? (note: in seconds)b. What is the minimum number of workstations?c. Draw a diagram of the production process.d. With the diagram that you have described above, can the production process run properly according to the plan? Explain the process of each workstation that you have created!.
[#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…

A production process at Kenneth Day Manufacturing is shown in Figure S7.9. The drilling operation occurs separately from, and simultaneously with, sawing and sanding, which are independent and sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel).a) Which operation is the bottleneck?b) What is the bottleneck time?c) What is the throughput time of the overall system?d) If the firm operates 8 hours per day, 20 days per month, whatis the monthly capacity of the manufacturing process?
