Improved Performance Models and Algorithms

Web-based software systems access some resources while executing the requests of the clients, typically several requests arrive at the same time, thus, competitive situation is established for the resources. In case of modeling such situation queueing model-based approaches are widely recognized. In our work, novel models and algorithms have been proposed to model the queue limit performance factor. In addition, the computational complexity and the limit analysis of the proposed models and algorithms have been provided. Moreover, the practical application of the results has been shown.
