The paper presents new approach for improving method for quality evaluation and selection of equipment (devices and machinery) by applying distinct functions. Quality evaluation and selection of devices and machinery is a multi-criteria problem which involves the consideration of numerous parameters of various origins. Original selection method with distinct functions is based on technical parameters with arbitrary evaluation of each parameter importance (weighting). Improvement of this method, presented in this paper, addresses the issue of weighting of parameters by using Delphi Method. Finally, two case studies are provided, which included quality evaluation of standard boilers for heating and evaluation of load-haul-dump (LHD) machines, to demonstrate applicability of this approach. Analytical Hierarchical Process (AHP) is used as a control method.
