Students have asked these similar questions
The bottleneck resource in a process has the least idle time. True or false?a. Trueb. False
A copy machine is available 24 hours a day. On a typical day, the machine produces 100 jobs. Each job takes about 3 minutes on the machine, 2 minutes of which is processing time and 1 minute is setup time (logging in, defining the job). About 20 Percent of the jobs need to be reworked, in which case the setup time and the processing time have to be repeated. The remainder of the time, the equipment is idle.
What is the OEE of the equipment?
answer:______percent
Which of the following statements is true?
In a factory operating at capacity, every machine and person should be working at the maximum possible rate.
One way to increase the effective utilization of a bottleneck is to reduce the number of defective units.

- Clinical supervision is a management practice that benefits from parallel processing. This helps students learn and succeed. If two tasks cannot be completed simultaneously, then the time spent waiting for the delayed task to begin might be used toward finishing the first task. The individual's productivity is increased and time is better controlled thanks to parallel processing.arrow_forwardThis is a step in a process that is the slowest compared tothe other steps. This step limits the capacity of the process.arrow_forwardTo find the bottleneck in a process with attrition loss, all we need to do is find theresource with the lowest capacity. True or false?a. Trueb. Falsearrow_forward
- If the takt time is shorter than the cycle time, the process needs to run faster. True orfalse?a. Trueb. Falsearrow_forwardWhich of the following statements is TRUE? Group of answer choices The bottleneck resource is the one that determines the capacity of a process, and thus its utilization is always 100%. Because there is excess capacity compared to the bottleneck resource, non-bottleneck resource is always under-utilized, and its utilization is less than 100%. The bottleneck resource constrains the flow of the process, and thus the flow rate is always the same as the bottleneck capacity. When process is capacity constrained, utilization tells us by how much demand exceeds capacity. It is always necessary to add more capacity to the bottleneck stage to increase the Flow rate of the process.arrow_forwardWhich of the following is likely to increase the utilization of a resource with a setup time?a. Increase the flow rate c. Decrease the batch sizeb. Decrease the processing time d. Increase the setup timearrow_forward
- People are served in a process with two resources. A worker in the first resource serves 28 people per hour and a worker in the second resource serves 14 people per hour. The first resource has 3 workers and the second resource has 5 workers. Demand occurs at the rate 14 people per minute (Instruction Round your answer to one decimal place) What is the implied utilization (%) of the second resource?___________arrow_forwardIn a service operation, we can compute the value-added time by simply looking at thelabor content. True or false?a. Trueb. Falsearrow_forwardEquivalent units measure the amount of work done during a period, expressed in terms of fully completed units of output. True Falsearrow_forward
- The resource with the largest total demand rate is the bottleneck. True or false?a. Trueb. Falsearrow_forwardWhat is the relationship between a process with rework and a process with scrap?a. Scrap and rework are not related.b. Scrap and rework are sequential processes. First, items are scrapped and then they arereworked.c. A process either has scrap or rework. The two are mutually exclusive. d. Scrap is a special case of rework in which flow units have to repeat all resources in the process up to the defectarrow_forwardConsider a process consisting of three resources. Assume there exists unlimited demand for the product, and that all activities are always performed in the following sequence. Resource 1 has a processing time of 6 minutes per unit. Resource 2 has a processing time of 3 minutes per unit. Resource 3 has a processing time of 5 minutes per unit. All three resources are staffed by one worker and each worker gets paid $14 per hour.
