Study and assessment of transport system operation efficiency

The article deals with an issue of complex systems operation efficiency, especially of the ones which are connected with transport. The operation of such systems aims at developing both passenger and load transportation in terms of safety, reliability, effectiveness and environment friendliness. These properties should be researched in a particular place and time that were earlier planned and selected. Operation effectiveness is an important component ofwidely understood social-economic and technological research, including assessment of the considered transport system. The concepts of operation efficiency, most frequently used in literature, express it as the relation between benefits (treated as profit or income in terms of economy) and costs. However, a ratio of two quantities, the flrst of which is evaluated positively, that is, aims at reaching the highest values and the other one being negative, is considered as the most important definition of efficiency. In some cases these quantities can assume constant values, treated as basic ones. It should be remembered, though, that in many cases the system goals are formulated in different terms than, e.g. economic ones. And the systems should be evaluated taking into consideration the goal achievement degree. The article deals with an analysis of distinguished values of selected assessment indices for an investigated transport system, and on this basis an assessment of the transport system operation efficiency, in a given period of time, has been made.
