Spatial queueing models help to evaluate the design of public safety systems such as fire,
emergency medical service, and police departments, where vehicles are sent to …

In this article, we model and analyse by using generalised stochastic Petri nets (GSPNs), an
inventory system according to the (s, Q) replenishment policy, Poissonian batch arrivals in …

The threshold policy for the restoration of an unreliable server in a service system with bulk
input and balking is investigated. The arriving customers in the queueing system are …

We consider the M/M/1→•, M/M/1/0 type retrial queueing system with state dependent
parameters. The intensities of input, service (at both stations) and retrials depend in an …

Cognitive radio (CR) is currently one of the most promising information transmission
technologies to deal with the problem of spectrum scarcity and spectrum underutilization in …

Ι XX MM GG priority model with second optional service and server breakdown is
investigated to 9 analyze the reliability characteristics. There are two types of customers; the …

In order to reduce energy consumption in wireless communication networks, the sleep mode
in the energy saving strategy and the threshold activation process of the base station are …

The failure of computer software system is inevitable and it is important to analyze the
performance of the system. It is equally important to consider the cost factor that occurs …

Multitasking or task switching has been a topic of interest and research in the field of
operations management. There has been a little yet no full proof as to how increasing …

In this paper, queueing behaviour of asynchronous priority-based internet router with self-
similar traffic input is analysed. As Markov modulated Poisson process (MMPP) emulates …
