摘要：This paper presents the way of identifying the influence of the tolerance of model pumps (TYPE 3PWR-SE) construction on the total efficiency.The identification of sensitive control dimensions (Value / Tolerance) of examined pumps has been made by means of the multi-valued logic and inductive decision trees.In order to confirm the obtained results,multiple-valued logic trees have been used in the paper according to algorithms for the minimization of individual logic functions.What is more,a specific monotonicity of values of the most key parameters has been determined for the investigated set of pumps having individual specification numbers.
