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.…

suppose tht a queueing system has two identical servers, and an exponential service-time distribution with a mean of 1/u=10minutes. furthermore, a customer has just arrived to find two in the system. how long would you expect him to wait before being able to start service?

A fast-food restaurant offers a variety of products: from pre-made packaged sandwiches to milkshakes with different flavors. Many customers order one item time, other customers order multiple items. Sometimes customers buy the pre- made items, and some customers actually ask the restaurant to cook their food while they wait. The restaurant manager has kept careful records of some queuing statistics over several weeks. According to this data, the staff needs 4 minutes on average to serve a random customer. On average, the restaurant served 120 customers on a given day. This restaurant is open from 9 AM to 9 PM every day, and has a single service counter. If you want to help the manager measure this restaurant's waiting line performance, which of the following should you use? Exponential Service Rate Model The Finite Source Model Constant Service Rate Model O The multi phase single channel model

Explain in a queueing analysis what are the most typical measurements of system performance?

When you are connected to a representative, it will be, with equal probability, somebody from the billing department, customer retention department, or marketing department. When talking to a billing representative, the time until the issue is resolved is distributed uniformly from 10 to 20 minutes. Customer retention specialist will resolve you issue in exactly 2 minutes. Marketing person will first discuss with you promotions and new offers (this time will be normally distributed with average 10 minutes and standard deviation 2 minutes) and then transfer you to a new representative, who will, again be from one of the three departments with equal probability. What is the expected time that you will spend on the phone?

Two methods are used to predict how many customers will call in for help in the next four days. The first method predicts the numbers of callers to be 49, 42, 46, and 50 for the four respective days. The second method predicts 48, 43, 47, and 49 for the four respective days. The actual numbers of callers turn out to be 50, 40, 45, and 48. Which method has the smaller mean absolute error (MAE)? O Both methods have the same MAE The second method. The first method O Cannot be determined

A series of thefts from your pharmacy area have occurred in the last six weeks. The director of security and the head of pharmacy services now require all persons working in the pharmacy department with access to drugs to clock out after their shifts and then go through a security check before leaving the building. Several employees have complained that they should be paid for this time because the security check is for the employer’s benefit. The director of security and the head of pharmacy services have responded that this security check is for the benefit of the employees to ensure that no one is unjustly accused. Is either party correct?  If so, which one and why?

In an M/MA queueing system, the arrival rate is 3 customers per hour and the service rate is 5 customers per hour. If the service process is automated (resulting in no variation in service times but the same service rate), what will be the resulting performance measurements? (Round your answers to 3 decimal places.) a. What is the utilization? Utilization b. What is the expected number of customers in the system (L)? Number of customers c. What is the expected waiting time (in hours) for the system (W)? Waiting time(in hours)

A large insurance company maintains a central computing system that contains a variety of information about customer accounts. Insurance agents in a six-state area use telephone lines to access the customer information database. Currently, the company's central computer system allows three users to access the central computer simultaneously. Agents who attempt to use the system when it is full are denied access; no waiting is allowed. Management realizes that with its expanding business, more requests will be made to the central information system. Being denied access to the system is inefficient as well as annoying for agents. Access requests follow a Poisson probability distribution, with a mean of 29 calls per hour. The service rate per line is 19 calls per hour. (a) What is the probability that 0, 1, 2, and 3 access lines will be in use? (Round your answers to four decimal places.) P(0) = P(1) = P(2) = P(3) = (b) What is the probability that an agent will be denied access to the…
