in this paper a single server queuing production system is considered which is subject to gradual deterioration. the system is discussed under two different deteriorating conditions. a planning horizon is considered and server which is a d/m/1 queuing system is gradually deteriorates through time periods. a maintenance policy is taken into account whereby the server is restored to its initial c...

Queuing models provide an attractive and highly-efficient alternative to simulation for quantifying traffic flow efficiency. Stationary Markovian queuing models in which both inter-arrival times and service times are exponentially distributed have been studied by the National Airspace System (NAS). However, stationary queues cannot account for peaks and valleys in demand that are commonly obser...

Accurate modeling of queueing dynamics is important in the design and analysis of Internet congestion control. However, as demonstrated in this paper, existing window-based queueing models [26,30] are often not capable of precisely capturing the transient behavior (i.e., self-clocking and burstiness) of TCP-like protocols and their resulting analysis may be inaccurate in practice. As one exampl...

The United States Marine Corps (USMC) currently operates a fleet of KC130 aerial refueling tanker aircraft. This paper uses queuing and simulation models to examine the USMC KC130 tanker requirement, contrasts the results and explores the budgetary implications of alternative fleet requirements. This analysis finds that queuing models don’t account for some of the complexities of aerial refueli...

The investigation of security lines and the stochastic processes that personify them is known as queuing theory. Its goal to use mathematics understand real-world scenarios, for example, a massive crowd waiting in line at bank, or tasks lining up on your smartphone's back end. In linear programming, how long wait time extent is, regularly hoped be which can achieved using models. does not alway...
