This paper deals with a change of states of power transmission system elements up to the achievement of boundary conditions based on a material fatigue. Depending on the level of change in states of elements, an estimation of a remaining working life of a power transmission system was given. Additionally, an estimation of a change of conditions of power transmission system elements , as well as the impact of states of elements on a power efficiency of a vehicle are presented . Besides an analytical consideration, the simulation models were created and the results of simulations presented.

Contemporary wine production, unlike traditional one, requires investments in certain technological equipment necessary for the production process itself. In order to assess the justification of the production improvement in this area, the application of the engineering economy methods is very suitable. Methods for evaluation of financial efficiency and improvement of alternatives have been used in this paper. Specific solutions and recommendations have been obtained.
