Introduction: The main task of cooling systems in the machine room a data center is to maintain optimal air parameters at inlet IT equipment accordance with applicable regulatory documents. If value temperature exceeds value, then so-called hot spots occur — operation such places can lead its overheating and failure. reason for occurrence violation circulation between cold aisles. Purpose study...

Here, we examine the capability of artificial neural networks (ANNs) in sensitivity analysis of the parameters of efficiency analysis model, namely data envelopment analysis (DEA). We are mainly interested to observe the required change of a group of parameters when another group goes under a managerial change, maintaining the score of the efficiency. In other words, this methodology provides a...

Introduction: Data envelopment analysis (DEA) is a data-oriented method for measuring and benchmarking the relative efficiency of peer decision making units (DMUs) with multiple inputs and multiple outputs. DEA was initiated in 1978 when Charnes, Cooper and Rhodes (CCR) demonstrated how to change a fractional linear measure of efficiency into a linear programming format. This non-parametric app...
