To determine the model that best fits the operations of the company will be analyzed elements based queuing system prior knowledge of the pattern of arrivals and served to customers over time. Input queue system Source: Population or potential clientele is considered queue models infinite since the queue system number of clients that can be in the system at each instant of time not influences the rate of arrival of new customers.

Following this evidence, we model the Input population as a source generating unlimited clients which are simplified as explained in section. This consideration implies that the last parameter in the queue system classification system according to the notation of Kendall (D refers to the population size input) is infinite and can be omitted. Another feature of this element is the statistical pattern of arrivals clients has been verified.

SCHEME OF QUEUES

This test involves a first parameter to the system by Kendall notation, since inter arrival times follow an exponential distribution. Cola: Although reserved for the formation of the queue at the counter space Local is limited, the capacity of the queue is considered infinite since there may be such number of customers waiting for service as all those who are willing to wait after joining the queue.

Also, say that it is a single queue which according to a FIFO discipline will select customers at the rate they are free servers have completed their tasks in relation to a client. The both the characteristics typical of this queue system element determines the nomenclature concrete of the parameters and (ante penultimate and penultimate, respectively) as Kendall's notation. The first can be omitted since it refers the capacity of the system is unlimited due to infinite queue size and the second, refers to the discipline of the tail and considering the case FIFO also may be omitted when the system denote.

Queuing system Optical Center

Service mechanism: The last element of the system is characterized on the one hand, by statistical pattern whose service time distribution was contrasted with putting the exponential relationship evident. This result causes the second Management of waiting queue system lines in the real case of an optical center in Kendall notation that times services are distributed according to an exponential distribution level confidence chosen. Furthermore, referring to the service mechanism are considered system four servers (shop) as are those found in the Local serving the generality of customers. Therefore, Kendall's notation for the representation model Optical would be:M/ M/ 4. The scheme of the system queue is presented through Figure 6: Figure 6.



Prepared Before starting, the value of the utilization queue system factor which is less occurs unit. Utilization factor: (Equation) Which means that the system works with an average queue models occupancy rate of 7.5% capacity. Moreover, this percentage also involves measuring the Population infinite (Customers Potential) Infinite Cola Server Clients catered Server Server4 Queuing system Optical Center Garcia GallegoThe above results following the application of the formulas T.C. are useful to analyze the system in terms of stability, of course that comply with regard to global data collected.
