Using the following data, solve the assembly-line balancing problem and calculate the efficiency of your solution. Use the longest task time for your decision criteria.
Note: Round your answer to the nearest whole percent.
Natura has to fill 7 orders for its clients. He requires placing the required product in work boxes and subsequently closing them properly so that the product reaches the customer correctly. The process consists of filling the box and later closing it. As the content of each box and the size of these is different, the filling and closing times of each order is different. These times are shown in the table below.

- 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.

The assembly line needs to produce 15 units per hour, and there is room for only four workstations. The tasks and the order in which they must be performed are shown in the following table. Tasks cannot be split, and it would be too expensive to duplicate any task.

There are no buffers between tasks. Task 1 and 2 produce "Part A", and Task 3 and 4 produce "Part B"; Task 5 assembles each unit of a finished product by combining one unit of "Part A" with one unit of "Part B". Using this, answer the next 3 questions: Tpt Cap. = 10 units/hour- Tpt Cap. = 15 units/hour Task 1 5 ● 8 10 15 20 Task 3 Tpt Cap. = 5 units/hour Task 2 Tpt Cap. = 8 units/hour Task 4 Tpt Cap. = 20 units/hour Task 5 In this scenario, how many units would Task 5 actually produce each hour?

Both barbers provide roughly the same experience and skill, but one is just a little bit slower than the other. The process flow in Figure 6.90 shows that all customers go through Steps B1 and B2 and then can be served at either of the two barbers at Step B3. The process ends for all customers at Step B4. The numbers in parentheses indicate the minutes it takes that activity to process a customer. Figure 6.9 Process Flow for Bill's Barbershop B1 (10) B2 B3-a (15) B3-b (10) B4 (9) 1.

Flo's Quick-Lube performs fast oil changes (A) and checks for tire pressure and wear (B) and brakes and alignment (C) according to the process flow indicated by the diagram below. Each incoming car is put on a jack while one technician performs task A and another simultaneously performs task B and a third performs task C (which must follow task B due to the limited space under the vehicle on the jack). The server for task A takes on average 3 minutes to process a job, the server for task B takes on average 2 minutes to process a job, and the server for task C takes on average 2 minutes to process a job. Server A can be operated in parallel with Servers B and C. All processing times are random and exponentially distributed, and jobs are allowed to queue in front of each server. (You can assume that the number of jacks is sufficient to allow any length of queue.) (a) AND B A C Figure 1: Flo's Process Flow What is the capacity of the process (in orders/minute)?arrow_forward
