In this paper, we present an exact discrete-time queuing analysis of a statistical multiplexer with a finite number of input links and whose arrival process is correlated and consists of a train of a fixed number of fixed-length packets. The functional equation describing this queuing model is manipulated and transformed into a mathematical tractable form. This allows us to apply the final valu...

This paper addresses the study of a linkage network of biserial queues linked to a common server with a multistage flowshop scheduling system having ‘m’ machines or servers in series under fuzzy environment. Waiting lines or queues are commonly occurred both in everyday life and in a variety of business and industrial situations. Also, the flowshop scheduling is an important task when a number ...

In this paper we firstly propose simple and computationally efficient wireless channel modeling algorithm that explicitly takes into account firstand second-order statistics of frame error observations. For this purpose we use discrete-time Markov modulated processes with at most single event (error) at any time slot. We then adopt the special solution of the inverse eigenvalue problem initiall...

Service reliability in a distributed queuing system can be assessed by means of the probability of successfully serving queued tasks in a heterogeneous network of nodes. Moreover, randomness in delays imposed by the communication medium adds to the uncertainties in the shared information among these faulty nodes, which complicates the dynamics of the queuing system. A novel approach based on st...

In the present study, a spectral finite element method is developed for free and forced transverse vibration of Levy-type moderately thick rectangular orthotropic plates based on first-order shear deformation theory. Levy solution assumption was used to convert the two-dimensional problem into a one-dimensional problem. In the first step, the governing out-of-plane differential equations are tr...

We study the stochastic machine replenishment problem, which is a canonical special case of closed multiclass queuing systems in Markov decision theory. The problem models the scheduling of processor repairs in a multiprocessor system in which one repair can be made at a time and the goal is to maximize system utilization. We analyze the performance of a natural greedy index policy for this pro...

Among the various existing models for the warehousing management, the simultaneous use of private and public warehouses is as the most well-known one. The purpose of this article is to develop a queuing theory-based model for determining the optimal capacity of private warehouse in order to minimize the total corresponding costs. In the proposed model, the available space and budget to create a...
