October 3 Average time required to performed the services provided by the system Sidst udgivet den 03-10-2016

The queues are a daily and ordinary phenomenon and occur in service systems, which demand for some services may not be satisfied sometimes directly from the capacity of system that provides the service, because of the random fluctuations observed in both the pace attendance and in every customer queue management service time from the system. The knowledge of the operational characteristics of service and queuing systems can lead to dramatic improvements in performance there. standby systems Wanted: probabilistic size that characterizes the time when in which system services requested by the daily operation and queue management system price during service demand. The client arrives to serve needs to remain in the system for a time which is generally greater than the average time required to performed the services provided by the system. This due to the random manner in which the search occurs and/ or and random length of service.

 Number of parallel demand service stations

Examples standby system: banks, traffic systems, hospitals, supermarkets, fire stations, repair shops etc. The problem of waiting System performance is evaluated based on the prices of certain key indicators (performance indicators- function meters, for example the average waiting time of a customer in the queue, the total average residence time of a client in the system, the average number of customers in the queue, the average number of customers in the system, employment rate of service position or positions service, etc. The capacity of a standby system is usually measured either queue management system price the number of parallel demand service stations or the average service rate (served by guests per unit time, corresponding to an average service time. The study of a service system is the Determination of the capacity to minimize the operating costs provided that the values of indicators system performance meet some minimum specifications. Starting with this section we analyze queuing systems we give some examples for the population of customers.

Mention some arrivals standards, like in the Poisson arrival process and then is a reference to the discipline of a queue in a system. We continue to their service times and leaving a system and close the notation of Kendall Introduction. The queuing theory (queuing theory is a branch of applied mathematics namely probability and operational research. He deals with mathematical models designed to study and explain the phenomenon of congestion resulting from the random arrival clients in a system, and the randomness observed in time their service. He began to grow in the early twentieth century initially motivated by problems that existed in the phone industry.

Prediction of queue management system

The last three decades has witnessed a boom, mainly due to applications finding of the telecommunications and electronics computers. Apart from these areas is another field in which developed queuing theory is that health is one with which we deal. The four main systems found in queuing theory are a single servant (point of service Many servants (many service points, arranged in parallel and independently Inexperienced servants Network queues (here there is dependence between the points service All four systems can be applied in the field of health [D. H Stimson, R. H Stimson Research in Hospitals: Diagnosis and Prognosis Hospital research and Educational Trust, Chicago. An introduction queue management system to management science quantitative approaches to decision making th ed, Thomson, Ohio pp-]. The possibility of any unit- customer not present in the system.

For example a simple servant could describe the tail created in a pharmacy, the system of many servants to describe the department of emergency which simultaneously examine many Doctors, the queuing networks can reflect entire flow present in daily basis in a polyclinic and the system by inexperienced servants in macroscopic level can simulate the national supply system emergency assistance where customers- patients served soon arrive at the point of service. Sharing of resources and waiting in queues is a phenomenon found in every area of modern life. On the line at the grocery store neighborhood until the queues of packets to internet routers, the analysis and prediction visit here of their behavior has gained immense importance. OR better allocation of resources, which, for example, could lead a reduction of average waiting in queue at a major bank is looking and may be auriferous. Important examples Operating characteristics of a queuing system as the average wait given below.
