Marginal Utility Approach for Quality of Service Evaluation in IT infrastructure

IT-services are corner stones of any computing IT-infrastructures. In order to make them working properly their quality should be evaluated, measured and controlled. A lot of researches were conducted on quality of service evaluation, and many approaches were discovered. However, there is still need for connecting user satisfaction as subjective parameter with objective parameters or key performance indicators.Possible way for connecting those characteristics is to use marginal utility function in order to define direct dependency between quality of experience and quality of service. This kind of solution was proposed in this research.
