today, in a competitive market, service organizations and producers have a great attention to optimization and customer satisfaction in order to become competitive. service organization must reduce the number of arrival, waiting time and service time in the queue to increase the customer satisfaction. in this paper by the aim of queuing theory we analyze the optimal amount of increment in a rep...

We define a class of anticipating flows on Poisson space and compute its RadonNikodym derivative. This result is applied to statistical testing in an anticipating queuing problem.

The application of Queuing Theory to quantify the relationships between trajectory uncertainties due to aviation operations, precision of navigation and control, and traffic flow efficiency in the National Airspace System is discussed. This work builds on a previous research effort on Markovian queuing network models of the NAS. Two approaches for incorporating the trajectory uncertainties in t...

one of the most important issues in the plant layout design especially in mass production organizations with high inter-plant logistics is‘material flow and inter-plant traffic analysis and its effects on the production capabilities or pauses in production lines. in this paper the inter-plant traffic analysis issue on the basis of single channel queue model (m/m/1) is analyzed in a carmaker c...

This paper introduces a new multiscale framework for estimating the tail probability of a queue fed by an arbitrary traffic process. Using traffic statistics at a small number of time scales, our analysis extends the theoretical concept of the critical time scale and provides practical approximations for the tail queue probability. These approximations are non-asymptotic; that is they apply to ...

There is a huge demand for the Internet as the number of services keeps increasing. One common service is database transaction processing. Currently most confidential information is maintained in a database, and whenever users want to access the information, the information is retrieved from the database over the network. In order to complete this transaction process successfully the network sh...

Fifty years ago, the author published a paper in Operations Research with the title, “A proof for the queuing formula: L = ãW ” [Little, J. D. C. 1961. A proof for the queuing formula: L = ãW . Oper. Res. 9(3) 383–387]. Over the years, L = ãW has become widely known as “Little’s Law.” Basically, it is a theorem in queuing theory. It has become well known because of its theoretical and practical...
