Concept explainers
a.
Interpretation: The expected numbers of jobs which are in queue with steady status along with number of jobs in the system have to be computed.
Concept Introduction:
FCFS basis- Normally, there is a process in attending the jobs or, customers. FCFS basis means attending a job or customer on First come first serve basis. In other words, the job/customer which/who comes first is attended first.
B.
Interpretation: The expected flow time along with the time spent in a queue with steady status have to be computed.
Concept Introduction:
Flow time: The time spent in a business process right from beginning to end is called the flow time. It is also called total processing time.
C.
Interpretation: The probability about the system being empty needs to be computed.
Concept Introduction:
Probability: Probability is the chance of an event occurring. Number of favorable outcomes must be divided by total number of possible outcomes to get the probability factor.
D.
Interpretation: The probability about the queue being empty needs to be computed.
Concept Introduction:
Probability: Probability is the chance of an event occurring. Number of favorable outcomes must be divided by total number of possible outcomes to get the probability factor.
e.
Interpretation: The probability about the flow time exceeding 10 minutes needs to be computed.
Concept Introduction:
Probability: Probability is the chance of an event occurring. Number of favorable outcomes must be divided by total number of possible outcomes to get the probability factor.

- A post office clerk operates with 75% utilization. The coefficient of variation for the service process is 0.6 and the coefficient of variation of the arrival process is 0.9. The average processing time is 4 minutes. What is the average time a customer spends in the system according to the single-server queue model? Multiple Choice ○ 7.02 minutes 4 minutes 11.02 minutes О 3.51 minutesarrow_forwardExplain the concept of queue and queue theory or waiting line theory and its importance in business A bank has only one counter for its customers. Suppose that the customers to the bank arrive at random with exponential inter arrival time and their mean inter arrival time is 10 minutes. Suppose the counter takes on an average 15 minutes to serve the customer and this also follow an exponential distribution. What percentage of time the bank counter is busy? On the average, how many customers are in the system? On the average, how many customers are in the queue waiting for the service? How long a customer will take to be out of the service system after being served? How long a customer to wait before being served? What is the probability that there are at most three customers in the system?arrow_forwardplease answer within 30 minutes.arrow_forward
- There is only one copying machine in the student lounge of the business school. Students arrive at the rate of λ=40 per hour (according to a Poisson distribution). Copying takes an average of 40 seconds, or μ=90 per hour (according to a negative exponential distribution). If the percentage of time used is 44% and the average length of the queue is 35 students and the average number is 80 then what is the average time spent waiting in the queue and the average time in the system (round your response to two decimal points).arrow_forwardCustomers arrive to a local bakery with an average time between arrivals of5 minutes. However, there is quite a lot of variability in the customers’ arrivals, asone would expect in an unscheduled system. The single bakery server requires anamount of time having the exponential distribution with mean 4.5 minutes to servecustomers (in the order in which they arrive). No customers leave without service.d. Calculate the probability a customer will spend more than an hour at the bakery(time in queue plus service time).arrow_forwardA supermarket has more than one server servicing at counters. The customer arrives in a Poisson fashion at the rate of 10 per hour. The service time for each customer is expected with a mean of 4 minutes. Find the probability of a customer has to wait for the service, average queue length, the average time spent by a customer in the queue.arrow_forward
- Currently, Commercial Banks have 1 unit of ATM machines to meet customer needs. It is known that there is an average of 15 customers in the system. Then it is also known that the average time spent by someone in the system is 10 minutes. Assume that the system follows M/M/1. The Commercial Bank operational manager is considering whether it is necessary to add 1 unit of ATM machine. What are your considerations? To strengthen the consideration, compare the queue length, queue length, and utilities before and after adding an ATM machine?arrow_forwardA self-service store employs one cashier at its counter. Nine customers 'arrive on an average every 5 minutes while the cashier can serve 10 customers in 5 minutes. Assuming Poisson distribution for arrival rate and exponential distribution for service time, find 1. Average number of customers in the system. 2. Average number of customers in the queue or average queue length. 3. Average time a customer spends in the system. 4. Average time a customer waits before being served. A.1arrow_forwardPatients arrive to a small hospital emergency room according to a Poisson process with an average rate of 1.5 per hour. Because service times for these patients vary considerably, the service times are accurately described by an exponential distribution. Suppose that the average service time is 26 minutes. If there is only a single doctor working at any point in time, find the following measures of service for this emergency room: The expected total time in the system. b. The expected time each customer has to wait. c. The expected number of patients waiting for service. d. If the emergency room has a triage nurse who gives priority to more serious conditions, explain qualitatively how that would change your results to parts a, b, and c. What additional information would one need to know to analyze a system like this?arrow_forward
- Mom and Pop own and operate the Fuzzy Belly Deli. On average, customers arrive at the deli every 6 minutes. Pop fulfills their orders one at a time. It takes him an average of 3 minutes to fulfill each order. Customers then proceed to the cash register, where Mom receives their payment. Mom loves to chat and is somewhat slow in operating the cash register, taking an average of 4 minutes to receive payment from each customer. Assume that customer interarrival times, as well as order fulfillment and payment times are exponentially distributed. What is the throughput of the deli's operation? What is the capacity of the deli's operation? On average, how long does a customer spend at the deli from the time she arrives until her order is fulfilled by Pop?arrow_forwardConsider a business process in which each order that arrives is split into two jobs that are performed in parallel and are then rejoined before leaving the system. Assume no variance in inter-arrival times nor in process times for each task. Each station (depicted by a rectangle) contains one or more identical parallel servers (depicted by circles). Each server is independent of all others and can work on one job at at a time. Process times for individual servers at station A are 5 minutes. Servers at stations B and C have process times of 3 and 6 minutes respectively. Consider the system with one server at each of the stations A and B as before, and two identical parallel servers (each with a 6 minute process time) at station C. What is the system's capacity? What is the cycle time for each order through the entire process flow?arrow_forwardConsider a business process in which each order that arrives is split into two jobs that are performed in parallel and are then rejoined before leaving the system.
