The Poisson probability distribution‚ named after the French mathematician Siméon-Denis. Poisson is another important probability distribution of a discrete random variable that has a large number of applications. Suppose a washing machine in a Laundromat breaks down an average of three times a month. We may want to find the probability of exactly two breakdowns during the next month. This is an example of a Poisson probability distribution problem. Each breakdown is called an occurrence in Poisson

Binomial‚ Bernoulli and Poisson Distributions The Binomial‚ Bernoulli and Poisson distributions are discrete probability distributions in which the values that might be observed are restricted to being within a pre-defined list of possible values. This list has either a finite number of members‚ or at most is countable. * Binomial distribution In many cases‚ it is appropriate to summarize a group of independent observations by the number of observations in the group that represent one of

Lab 2 2.2.1 The mean arrival rate of the number of users in a particular cell making a call in the busy hour and the time interval of those calls is calculated. Every user makes a call in an interval by using the uniform random number. If this number exceeds 1-mean arrival rate or is equal to the mean arrival rate‚ then a call is generated which is referred as poisson threshold. 2.2.2 In this case the green line indicated the poisson threshold. When the customer uniform random number exceeds

The items arrive at the queue in a Poisson process‚ and processing times at the workstation are independent with an unspecified distribution‚ so that the queue operates as an M/G/1 system. The arrival rate to the queue is 20 items per hour‚ and the mean processing time at the workstation is 2.4 minutes. It is observed that the number of items in the system‚ N‚ has

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
