Optimization of problem solving process in the computer centre

Formation and operation of adaptive computer centre requires development of a system of models for linking the characteristics of problem solving process with the characteristics of computer centre as such and its components. The article proposes a model of time minimization to solve problems by the users by means of determining the optimal throughput of input/output channels and optimal performance of computer equipment for each problem. The model was created for transactional class of problems (application systems, applications). Implementation of adaptive computer centre allows reducing the number of servers required for running the applications, increase reliability and robustness of applications under failuremalfunction situations (disasters) and during scheduled shutdowns of computer equipment.
