This paper presents the derivation of an analytical model for a multi-queue nodes network router, which is referred to as the multi-queue nodes (mQN) model. In this model, expressions are derived to calculate two performance metrics, namely, the queue node and system utilization factors. In order to demonstrate the flexibility and effectiveness of the mQN model in analyzing the performance of a...

The rapid development of information technology has promoted the transformation traditional networks into intelligent networks. Huge data traffic is generated by various types services in networks, which can easily lead to network congestion, system instability, and other problems. These problems may incur great requirements pose challenges for queue management algorithms. Most active (AQM) alg...

A new mathematical model based on the alternative process routings in presence of a queuing system in a dynamic cellular manufacturing system has been proposed in this paper.This model integrates two problems of cell formation and inter-cell layout and also an efficiency factor which is defined for minimizing the cell load variation through the maximizing the busy time for all machine types. In...

Queue length is an important parameter for traffic-signal priority systems emergency vehicles. Instead of using conventional detector data, this paper investigates the feasibility queue-length estimation Google Maps color-code data via random forest (RF) and gradient-boosting machine (GBM) methods. Alternative ways specifying independent variables from are also investigated. Additionally, model...

We treat a single–server vacation queue with queue–length dependent vacation schedules. This subsumes the single–server vacation queue with exhaustive service discipline and the vacation queue with Bernoulli schedule as special cases. The lengths of vacation times depend on the number of customers in the system at the beginning of a vacation. The arrival process is a batch–Markovian arrival pro...
