A study of queuing system Queueing theory is the mathematical study of waiting lines‚ or queues. The theory enables mathematical analysis of several related processes‚ including arriving at the (back of the) queue‚ waiting in the queue (essentially a storage process)‚ and being served at the front of the queue. The theory permits the derivation and calculation of several performance measures including the average waiting time in the queue or the system‚ the expected number waiting or receiving service

checkout at a supermarket‚ or waiting to make a bank deposit. Queuing theory‚ started with research by Agner Krarup Erlang‚ is used to examine the impact of management decisions on these waiting lines (Anderson et.al‚ 2009). A basic Queuing Model structure consists of three main characteristics‚ namely behaviour of arrivals‚ queue discipline‚ and service mechanism (Hillier and Lieberman‚ 2001). In this assignment‚ New England Foundry’s queuing problem will be solved in Excel‚ and then‚ time and cost

QUEUING THEORY INTRODUCTION Waiting lines are the most frequently encountered problems in everyday life. For example‚ queue at a cafeteria‚ library‚ bank‚ etc. Common to all of these cases are the arrivals of objects requiring service and the attendant delays when the service mechanism is busy. Waiting lines cannot be eliminated completely‚ but suitable techniques can be used to reduce the waiting time of an object in the system. A long waiting line may result in loss of customers to an organization

Problem 1 A gas station with only one gas pump employs the following policy: if a customer has to wait‚ the price is $3.50 per gallon; if they don’t have to wait‚ the price is $4.00 per gallon. Customers arrive according to a Poisson process with a mean rate of 20 per hour. Service times at the pump have an exponential distribution with a mean of 2 minutes. Arriving customers always wait until they can by gasoline. Determine the expected price of gasoline per gallon. Problem 3 The Old Colony theme

TOPIC VII QUEUING THEORY Definition A queue can be defined as items awaiting service. Queues may consist of people‚ cars‚ components awaiting machining‚ telephone calls‚ aeroplanes‚ indeed any discrete items. Queues form when the rate of arrival of items requiring service is greater than the rate of service. Queuing theory can be defined as the construction of mathematical models of various types of queuing systems so that predictions may be made about how the system works

Long Queuing Time Pepper lunch restaurant is famous for providing hot‚ fast and delicious food to customers. It attracts many people to visit‚ no matter in peak hours or off peak hours. However Pepper Lunch Restaurant have a poor queuing for customers to buy their wanted dishes. According a servey‚ a customers said that when he buying a meal‚ he counted from queuing to get a meal on the get dishes area‚ it takes around 45minutes in peak hour while it takes at least 15 minutes in off peak hours.

The Alpha’s Quandary Calfus rose from nothing. A mother and father that couldn’t provide in their pack‚ a family shattered by their animalistic greed for the position of alpha. Calfus learned at a young age that in order to provide for his stomach‚ it was no one’s job but his own. His pack hardly a union‚ but a loose collection of wolves who fear a lonesome life. Long Summers and cold Winters passed‚ all while he learned what he needed and fended for his life. One day‚ Calfus confronted his parents
