We consider a single server queue with disasters where the arrivals of customers and disasters are correlated. When a disaster occurs, it removes all the customers in the system and there requires repair time for the system to be operated normally. The stationary queue length distribution at the embedded points and at an arbitrary time are presented. 相似文献

We define and analyze anM/G/1/N vacation model that uses a service discipline that we call theE-limited with limit variation discipline. According to this discipline, the server provides service until either the system is emptied (i.e. exhausted) or a randomly chosen limit ofl customers has been served. The server then goes on a vacation before returning to service the queue again. The queue length distribution and the Laplace-Stieltjes transforms of the waiting time, busy period and cycle time distributions are found. Further, an expression for the mean waiting time is developed. Several previously analyzed service disciplines, including Bernoulli scheduling, nonexhaustive service and limited service, are special cases of the general varying limit discipline that is analyzed in this paper. 相似文献

We survey the rate conservation law, RCL for short, arising in queues and related stochastic models. RCL was recognized as one of the fundamental principles to get relationships between time and embedded averages such as the extended Little's formulaH=G, but we show that it has other applications. For example, RCL is one of the important techniques for deriving equilibrium equations for stochastic processes. It is shown that the various techniques, including Mecke's formula for a stationary random measure, can be formulated as RCL. For this purpose, we start with a new definition of the rate with respect to a random measure, and generalize RCL by using it. We further introduce the notion of quasi-expectation, which is a certain extension of the ordinary expectation, and derive RCL applicable to the sample average results. It means that the sample average formulas such asH=G can be obtained as the stationary RCL in the quasi-expectation framework. We also survey several extensions of RCL and discuss examples. Throughout the paper, we would like to emphasize how results can be easily obtained by using a simple principle, RCL. 相似文献

Importance of verifying queue model assumptions before planning with simulation software 总被引:1,自引:0,他引:1

This case study uses empirical data gathered at an Australian refinery to verify the assumptions for queue distributions before using special-purpose software to plan the off-road-truck hauling of titanium dioxide to a refinery (n = 773). Easy-to-use spreadsheet software is utilized to verify assumptions for queue models. Managers are able to make decisions based on economic implications of queue models to avoid making costly planning mistakes. Analysts can use nonparametric hypothesis-testing techniques to verify distribution assumptions for optimization without having to write hard-to-maintain and complex algebraic linear equations or nonlinear search routines. 相似文献

All studies in the admission control of a service station make decisions at arrival epochs. When arrivals are internal and
are rejected from a queue, the rejected jobs have to be routed to other stations in the system. However the system will not
know whether a job will be admitted to a queue or not until its arrival epoch to that queue. Thus, the system has to react
dynamically and agilely to the decisions made at a specific queue and may try several queues before finding a queue that admits
the job. This paper remedies these difficulties by changing the decision epochs of the admission control from arrival epochs
to departure epochs with the actions of switching (keeping) the arrival stream on or off. Thus upstream stations will have
information on the admission status of their downstream stations all the time. It is proved that the optimal policy for this
revised admission control system is of control limit type for an M/G/1 queue. Comparisons of the optimal values and optimal
policies for the admission controls made at arrival epochs and at departure epochs are included in the paper. 相似文献

We consider a single-server first-in-first-out queue fed by a finite number of distinct sources of jobs. For a large class
of short-range dependent and light-tailed distributed job processes, using functional large deviation techniques we prove
a large deviation principle and logarithmic asymptotics for the joint waiting time and queue lengths distribution. We identify
the paths that are most likely to lead to the rare events of large waiting times and long queue lengths. A number of examples
are presented to illustrate salient features of the results.
