Consider the following four-step assembly operation with quality problems. All resources arestaffed by one employee.• The first resource has a processing time of 5 minutes per unit.• The second resource has a processing time of 6 minutes per unit.• The third resource has a processing time of 3 minutes per unit. With a 30 percent probability,the flow unit coming out of the third resource has to be reworked. In that case, the operations atthe first, second, and third resources are repeated. You can assume that (a) rework alwayssucceeds (i.e., a unit going through the rework loop will always work after the third resource)and (b) the processing times for units in rework are the same as for regular units.• The fourth resource has a processing time of 4 minutes per unit.With this information in hand, answer the following questions:• What is the bottleneck process?• What is the capacity of the process?

Answered: Consider the following four-step…

A machine makes two components; call them types A and B. It takes 630 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 4 seconds, or 15 units per minute. Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. In that case, what is the capacity of the machine in component pairs per minute, where a component pair is one unit of A and one unit of B? Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. What is the utilization of the machine? Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. What is the average inventory of B components? If the production schedule could be adjusted with…
The following table shows the process times in minutes (or minutes/unit - how many minutes to process one unit) of a six-station serial production line (1-2-3-4-5-6). Station 1 2 3 4 5 6 Which station(s) is (are) the bottleneck(s)? Station 2 Station 5 Stations 3 and 4 Stations 2 and 5 Process Time (minutes/unit) 8 11 7 7 11 4
These four phases make up a machine cycle, which is also known as a process loop. What percentage of a machine's cycle time do you value the most? Should I be concerned about replacing parts of the machine cycle when they wear out? Is the problem of switching modules improved by adding a second module?
The following diagram represents a process where two components are made at stations A1 and A2 (one component is made at A1 and the other at A2). These components are then assembled at station B and moved through the rest of the process, where some additional work is completed at stations C, D, and E. Assume that one and only one person is allowed at each station. Assume that the times given for each station represent the amount of work that needs to be done at that station by that person, with no processing time variation. Assume that inventory is not allowed to build in the system. What is the average hourly output of the process when it is in normal operation?

A new process should be checked for whether there are significant bottlenecks or steps with capacity that greatly exceed the overall process flow rate, which is a check for a. automation. b. measurement. c. balance. d. sequence
Within a process approach the desired results are most effectively achieved when: Select one: related activities are part of the process. Resources and related activities are managed as a process. the process includes the resources.

Balancing a process with a fixed sequence of activities will achieve a higher average labor utilization than balancing a process with no fixed sequence of activities. True or False?
