A 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)?
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.
A graphics reproduction i rm has four units of equipment that are automatic but occasionallybecome inoperative because of the need for supplies, maintenance, or repair. Eachunit requires service roughly twice each hour, or, more precisely, each unit of equipmentruns an average of 30 minutes before needing service. Service times vary widely, rangingfrom a simple service (such as pressing a restart switch or repositioning paper) to moreinvolved equipment disassembly. The average service time, however, is i ve minutes.Equipment downtime results in a loss of $20 per hour. The one equipment attendant ispaid $6 per hour.Using i nite queuing analysis, answer the following questions:a. What is the average number of units in line?b. What is the average number of units still in operation?c. What is the average number of units being serviced?d. The i rm is considering adding another attendant at the same $6 rate. Should the i rmdo it?

- An engineering i rm retains a technical specialist to assist four design engineers workingon a project. The help that the specialist gives engineers ranges widely in time consumption.The specialist has some answers available in memory, others require computation,and still others require signii cant search time. On the average, each request for assistancetakes the specialist one hour.The engineers require help from the specialist on the average of once each day. Becauseeach assistance takes about an hour, each engineer can work for seven hours, on the average,without assistance. One further point: Engineers needing help do not interrupt if thespecialist is already involved with another problem.Treat this as a i nite queuing problem and answer the following questions:a. How many engineers, on average, are waiting for the technical specialist for help?b. What is the average time that an engineer has to wait for the specialist?c. What is the probability that an engineer will have to wait…arrow_forwardPeople 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.

Before starting to produce a board, the PCB machine requires a 16-minute setup. Once in production, the PCB machine requires only 0.19 minute per board. a. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per min)? b. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the utilization of the PCB machine? c. Say the PCB machine produces 400 boards s between setups and demand is 2 boards per minute. Given the operating process, what is the avergae inventory of boards anf the PCB machine? d.

- You observe a bank and notice that a customer leaves the bank about every five minutes.These five minutes between customers are:a. the capacity of the process.b. the processing time of the last resource.c. the cycle time.d. the lead timearrow_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_forwardThe bottleneck resource in a process has the least idle time.

Prior to buying the new equipment, the company used five workers, who produced an average of 80 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour, while output increased by four carts per hour.A) Compute labor productivity under each system. Use carts per worker per hour as themeasure of labor productivity.B) Compute the multifactor productivity under each system.
