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)?
If the batch size is increased, inventory increases, which implies that flow units arelikely to spend more time in the process. True or False?a. True b. False
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 time

- Mrs. Freddy Mitchell, in her lecture, stated that a transaction processing system (TPS) is software that ensures the completion of business transactions and keeps track of those business transactions. An online transaction processing system (OTPS) is an equivalent system that online merchants use for e-commerce. The TPS ensures that each transaction is successful by storing, sending, and receiving information via a database. She added that because the process is lengthy, it is broken down into cycles, which are broken further into systems and subsystems. Zara- Lee, a participant in Mrs. Freddy Mitchell’s Lecture series, got confused as Mrs. Freddy Mitchell began to elaborate on the many different systems, and Zara- Lee mentioned to YOU that she is experiencing information overload. YOU then responded that Mrs. Freddy Mitchell’s explanation was clear and concise, and YOU would explain the revenue cycle, its components, and the sub-systems that constitute that cycle after class.…arrow_forwardIncreasing the batch size on a resource with setups always increases the capacity of theresource.

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_forward
