Larry Ellison starts a company that manufactures high-end custom leather bags. Hehires two employees. Each employee only begins working on a bag when a customerorder has been received and then she makes the bag from beginning to end. The average production time of a bag is 1.8 days, with a standard deviation of 2.7 days. Larryexpects to receive one customer order per day on average. The interarrival times oforders have a coefficient of variation of one. What is the expected duration, in days,between when an order is received and when production begins on the bag?
A small mail order firm Seas Beginnings has one phoneline. An average of 60 people per hour call in orders, and ittakes an average of 1 minute to handle a call. Time between
calls and time to handle calls are exponentially distributed.If the phone line is busy, Seas Beginnings can put up toc 1 people on hold. If c 1 people are on hold, a callergets a busy signal and calls a competitor (Air End). SeasBeginnings wants only 1% of all callers to get a busy signal.
How many people should the company be able to put onhold?

Each customer arrives in a Poisson stream with mean value 4 minutes. They are serviced at the rate of 10 per hour. For simplicity, assume that customers are serviced one at a time by one waiter. c) Suppose that two customers (with random arrival times) would like to be seated together. What is the probability that their wish can be fulfilled? Assume that arrangements can be made to seat them together as long as there are three empty seats anywhere in the cafeteria. d) Determine the expected number of customers waiting but currently not being servedarrow_forwardA copier store has four pieces of automatic equipment, but sometimes they are down because they need supplies, maintenance or repair. Each unit requires about two services every hour or, to be exact, each piece of equipment runs an average of 30 minutes before needing service. Service times vary greatly, from a simple service (such as pressing the reset switch or replenishing the paper) to disassembling the equipment in question. However, the average service time is five minutes. The time the equipment is down generates a loss of $60 per hour. The single employee who services the equipment earns $18 per hour. Using finite population analysis, answer the following questions: a. What is the average number of units idling? b. What is the average number of units still operating? c. What is the average number of units being serviced? d. The company is considering adding another manager at the same wage of $18 per hour. should it do so?arrow_forward
- Based on Quinn et al. (1991). Winter Riggers handles approximately $400 million in telephone orders per year. Winter Riggers’ system works as follows. Callers are connected to an agent if one is available. Otherwise, they are put on hold (if a trunk line is available). A customer can hang up at any time and leave the system. Winter Riggers would like to efficiently manage the telephone system (lines and agents) used to process these orders. Of course, orders are very seasonal and depend on the time of day. a. What decisions must Winter Riggers make? b. What would be an appropriate objective for Winter Riggers to minimize (or maximize)? What difficulties do you see in specifying the objective? c. What data would Winter Riggers need to keep track of to improve its efficiency?arrow_forwardOn average, 100 customers arrive per hour at theGotham City Bank. The average service time for eachcustomer is one minute. Service times and interarrivaltimes are exponentially distributed.

Jim McDonald, manager of the fast-food hamburger restaurant McBurger, realizes that providing fast service is a key to the success of the restaurant. Customers who have to wait very long are likely to go to one of the other fast-food restaurants in town next time. He estimates that each minute a customer has to wait in line before completing service costs him an average of 30 cents in lost future business. Therefore, he wants to be sure that enough cash registers always are open to keep waiting to a minimum. Each cash register is operated by a part- time employee who obtains the food ordered by each customer and collects the payment. The total cost for each such employee is $9 per hour. During lunch time, customers arrive according to a Poisson process at a mean rate of 66 per hour. The time needed to serve a customer is estimated to have an exponential distribution with a mean of 2 minutes. Determine how many cash registers Jim should have open during lunch time to minimize his…arrow_forward
- A manufacturing facility stores spare parts for maintenance in a storage facility. Throughout theworking day, manufacturing personnel go to the storage facility to pick up supplies needed for theirjobs. The storage facility employees receive a request for supplies, on average, every five minutes fromthe manufacturing personnel. The average request requires 3.2 minutes to fill a request. Manufacturingpersonnel are paid $29.50 per hour and storage facility employees are paid $18.75 per hour. The storagefacility operates 8 hours per day. Base your costs on an 8-hour workday, the given arrival and servicerates, and the fact that when the manufacturing personnel are at the storage site picking up parts – theyare unable to complete their normal job in manufacturing.a) What is the system cost per day (to the nearest $) if there is only 1 storage facility employeeworking?b) What is the system cost per day (to the nearest $) if there are 2 storage facility employeesworking?c) What is the system…arrow_forwardConsider a Poisson queue with the following steady-state probabilities: po = 1/3, p1 = 1/2, p2 = 1/6, and pn = for n = 3,4,5, ... .

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_forward
