Question
Chapter 7.3, Problem 14P
Summary Introduction
Interpretation: estimate the squared coefficient of variation of the arrival process.
Concept introduction:Poisson arrivals are a reasonably good assumption for unscheduled systems. Further if there is a mix of many different types of jobs the exponential distribution can be realistic for service times. Otherwise it tends to be too variable of a distribution.

The following data has been collected on the number of customers seen to arrive to a museum in a succession of 5-minute intervals: 5, 1, 3, 7, 5, 5, 6, 7, 5, 7, 4, 8, 1, 5, 2, 3, and 5. Estimate the squared coefficient of variation of the arrival process. If this data was known to come from a Poisson process, what would be your estimate of λ, the rate of customer arrivals?

- How does an event improve the smooth queue management?arrow_forwardA number of decision may be need to made when designing a queueing system . What are they explain?arrow_forwardAn insurance company receives 220 calls per day from customers who lodge insurance claims. The call center is open from 8 a.m. to 5 p.m. The arrival of calls follows a Poisson process. Looking at the intensity of arrival of calls, we can distinguish three periods during the day: the period 8 a.m. to 11 a.m., the period 11 a.m. to 2 p.m. and the period 2 p.m. to 5 p.m. During the first period, around 60 calls are received. During the 11 a.m. to 2 p.m. period, 120 calls are received, and during the 2 p.m. to 5 p.m. period, 40 calls are received. A customer survey has shown that customers tend to call between 11 a.m. and 2 p.m. because during this time they have a break at work. Statistical analysis shows that the durations of calls follow an exponential distribution. According to the company’s customer service charter, customers should not wait more than 1 min on average for their call to be answered. • Assume that the call center can handle 70 calls per hour using 7 call center…arrow_forward
- Consider a bank branch that has three distinct customer arrival patterns throughout the day, as measured by average arrival rates (below). Morning (8:30 - 11:30): arrival 1 = 47 per hour. %3D Lunch (11:30 - 1:30): arrival 2 = 70 per hour. Afternoon (1:30 - 4:00): arrival 3 = 30 per hour. Regardless of the time of day, the average time it takes for a teller to serve customers is 3.17 minutes. Because of competition with other banks in the area, management has developed an internal goal to keep the average customer wait before service to be less than 4 minutes. With that in mind, answer the following: a. During the morning period, what is the minimum number of tellers that the bank needs to hire to achieve the 4-minute service goal mentioned above? [ Select] b. During lunch, what is the minimum number of tellers that the bank needs to hire to achieve the 4 minute service goal mentioned above? [ Select ] c. In the afternoon, what is the minimum number of tellers that the bankarrow_forwardDescribe the important operating characteristics of a queuing system.

- Waiting Line ApproximationLet’s consider an example of a call center that takes orders for a mail-order business. During the peak period, the average time between call arrivals (¯X a ) is 0.5 minutes with a standard deviation (Sa) of 0.203 minutes. The average time to service a call (¯ X s ) is 4 minutes and the standard deviation of the service time (Ss) is 2.5 minutes. If the call center is using nine operators to service calls, how long would you expect customers to wait before being serviced? What would be the impact of adding an additional operator?arrow_forwarda single-server waiting line system has an arrival pattern characterized by a poisson distribution with 24 customer per hour. on average 30 customer are served per hour the service times are distributed according to the negative exponential distributionarrow_forwardWhat are the companies that are engaging and practice queuing models?arrow_forward
