In this thesis a fluid queue driven by single server Markovian queue with variant working vacation was investigated. Queuing theory is a mathematical approach that studies and models waiting lines. A fluid Queue is an input ...

In this thesis an infinite capacity Multi server Markovian queuing system with multiple working vacations, waiting server, feedback, reneging and retention of reneged customers is examined. If all active servers finish ...

This research investigates a single server batch service queuing system with Poisson arrivals, exponential service times and a server that takes variant working vacations. During working vacation, the server continues to ...

Formulating and solving IQPP is a very interesting and challenging problem. The main difficulty is that if the constraints have interval coefficients, then the feasible region is not fixed. Instead there are an infinite ...

The particle swarm optimization algorithm has been successfully shown to perform well on various optimization problems. Nevertheless, it may be easy to get trapped in a local optimum (premature convergence) when solving ...

In this study, tenth order multi-step predictor-corrector method is formulated for solving the generalized quadratic Riccati differential equations. In order to formulate this method, first, the interval is discretized ...

In this thesis a heterogeneous two servers Markovian queue with differentiated vacations, waiting server, reneging and retention of reneged customers was analyzed. The server serves the customers on a first-come, first-served ...
