Process time is part of cycle time. The process time of a business process refers to:
a. alWways is the largest part of cycle time.
b. timMe a customer spends waiting in a queue (e.g., time customer spends waiting in a drive-thru line)
c. is ofFten considered to be value-added time to the customer.
d. timMe from beginning to completion of the business process.
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 113 Jobs. Each Job takes about 4 minutes on the
machine, 2 minutes of which is processing time and 2 minute is setup time (logging in, defining the job). About 16 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?
(Round your percentage answer to 1 decimal place.)
What is the OEE of the equipment?

- In a multi-station serial process system, the capacity of the system is the equal to the capacity of the station that has the highest capacity among all stations. True Falsearrow_forwardA 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.

- . A resource has an implied utilization of 150 percent. This is the highest implied utilization in the process. This means that the resource is the bottleneck. True or false?a. Trueb. Falsearrow_forwardThe slowest point in a process is a ________. Group of answer choices Bottleneck Lost production Surplus Throughputarrow_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
- 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_forwardThe resource with the largest total demand rate is the bottleneck. True or false?a. Trueb. Falsearrow_forwardWhich of the following most directly expresses the motivation behind the expression "Do not block the bottleneck"? Multiple Choice O O O If the bottleneck has nothing to work on, the overall capacity of the process will be lower than it could be. If the bottleneck is prevented from working (e.g., it has nowhere to put its output), the overall capacity will be reduced. Blocking the bottleneck will increase the coefficient of variations of the arrival process, which decreases capacity. Blocking the bottleneck increases inventory turns, which increases the annual holding costs. It is not good to block the bottleneck because there are economies of scale in inventory management.arrow_forward
- Blue Lotus is a bike shop located near a beach resort, which rents its bikes to guests staying in the resort. When a customer requests to rent a bike and no bikes are available (they are either with another customers or being cleaned for rental), customer waits until a bike is available. Once a bike rented out to a customer, the customer keeps it for an average of 1 day. Upon return, the bike is cleaned and tuned-up, which takes half a day (0.5 day). Suppose Blue Lotus has 7 bikes, and demand for bike rental is 4.1 per day. What is the average amount of time a customer waits to receive a bike? (Hint: From the perspective of customer waiting time, 0.5 day of cleaning time would be part of the processing time" so, p = 1+0.5 =1.5 days. Assume CVa = CVp = 1 in your calculations). O 1.197 days O2.134 days O 0.761 days O 5.380 daysarrow_forwardAn average of 1200 parts arrive to the EP chamber during an 8-hour workday. Each part goes through two stages of processing. At each stage, a single product is processed at a time, and processing takes an average of 15 seconds at the first station and 12 seconds at the second station. Inter-arrival times and service times are exponentially distributed. At the end of the second step, the product goes through a quality check. 5% of the parts fail the quality check and are sent back to the second stage of service. Parts exit the system only after they pass the quality check. Ignoring the time required to perform the quality check or in moving the part through the facility, what is the average cycle time for parts?arrow_forward67. The number of resources requested by a process : a. must always be less than the total number of resources available in the system b. must always be equal to the total number of resources available in the system c. must not exceed the total number of resources available in the system d. must exceed the total number of resources available in the systemarrow_forward
