Abstract
With the efficient influence on making an adequate and prompt managing decision it is possible to improve operation of any system. This study presents one of the possible ways of exerting influence on the information and material flow so that the management could make optimal decisions in the system of parts regeneration which exists in a multilevel system of supplying the spare parts. The optimization process consists of generating functional variants in the system of supply with regenerated parts, then determining the values of characteristics of these variants and forming the model of multi-criteria decision making. Flow variants were determined by using modelling and simulation and the method of multiple attribute decision (Analytic Hierarchy Processes-AHP in this case). Variants were analyzed and after that, some conclusions were adopted. This is an example of how it is possible to make right decisions with the purpose of getting the user’s satisfaction and on the other hand also reducing the costs within the system, direct or indirect ones.
