Chapter 3, Problem 8PA
Consider a four-step serial process with processing times given in the following list. There is one machine at each step of the process, and this is a machine-paced process.
- Step 1: 25 minutes per unit
- Step 2: 15 minutes per unit
- Step 3: 30 minutes per unit
- Step 4: 20 minutes per unit
Assuming that the process starts out empty, how long will it take (in hours) to complete a batch of 105 units? [LO3-5]

Consider the following batch-flow process consisting of three process stepsperformed by three machines.
Process steps

45 min
Work is processed in batches at each step. Before a batch is processed at a step, the machine atthat step must be set up. (During a setup, the machine is unable to process any product.) Assumethat there is a dedicated setup operator for each machine (i.e., there is always someone availableto perform a setup at each machine.)a. What is the capacity of step 1 if the batch size is 35 parts?b. For what batch sizes is step 1 (2, 3) the bottleneck?
Consider a parallel process with two stages where the processing time of each stage is 15 minutes
per unit. What is the minimum cycle time of the parallel process in minutes per unit? Answer with
one decimal place (e.g., 20.1), if your answer involves any decimals. Provide only the number (do not
put "min/unit").
Consider a production line with five stations in serial. The stations have the following process times in minutes (or minutes/unit).
Station 1's process time is 9 minutes/unit. Station 2's process time is 10 minutes/unit. Station three has two identical machines, each of which process a unit in 12 minutes (each unit only needs to be processed on one of the two machines). Station 4's process time is 5 minutes/unit. Station 5's process time is 8 minutes/unit. Which station is the bottleneck station?
a)
Station 3
b)
None of the other options
c)
Station 2
d)
Station 5

Step 1 requires 4 minutes per unit, step 2 requires 6 minutes per unit and step 3 requires 2 minutes per unit. 40% of units that complete the third step require rework, which means those units must start the process over at step 2 (processing times are the same for units being reworked) and rework is always successful. Demand at the shop is 0.8 units per minute. Instruction: Round your answer to three decimal places.

- While designing a process, we try to ensure that unpleasant experiences such as filling forms or taking shots are located towards the beginning/middle, primarily because: O It is usually more convenient to complete such tasks early on None of the above We do not wish to end on an unpleasant note. The memory of unpleasant experiences stays much longer relative to other kinds of experiences. O The customer may refuse to do/participate in such unpleasant tasks at the end of the processarrow_forwardThis is a step in a process that is the slowest compared tothe other steps. This step limits the capacity of the process.arrow_forwardA lab provides ultrasound service to patients. The service process consists of two steps: 1. Registration. Performed by a receptionist (Salary rate = $25/hr; Process time = 6 minutes/patient) 2. Ultrasound scan. Performed by a technician (Salary rate = $30/hr; Process time = 20 minutes/patient) Note that the ultrasound images need to be read by radiologists, but we assume that they have an ample capacity and thus will not model the role in the service process. Currently, the lab has 2 receptionists and 3 technicians. The manager anticipates demand to grow to 14 patients/hr in the near future. Thus, he plans to hire more receptionists and/or technicians to increase the service capacity to at least 14 patients/hr. What would be the extra payroll cost (in dollars per hr)?arrow_forward

For 40 percent of wafers, they make only a single pass through the stepper. But 60 percent of wafers need to make a second pass through the stepper. The processing time on the second pass is 40 minutes. Instruction: Round your answer to 2 decimal places. How many wafers does the stepper complete per hour (wafers/hr)? per hourarrow_forward
- There is a manufacturing company that has a dedicated production line to make one specific product. The line has three stations working in serial. Inputs arrive at station 1 and the output from station 1 becomes the input to station 2. The output from station 2 is the input to station 3. The output from station 3 is the finished product. Station 1 can process 500 units per week, station 2 can process 300 units per week, and station 3 can process 400 units per week. illustrates this problem.
