technical object - Opis:
- The article presents a determination method of transport means service ability in a real city transport system. The considerations have been demonstrated on the basis of a real city bus transport system in a chosen agglomeration. The executive subsystem consisting of elementary subsystems of the type human - technical object (operator - transport means) whose service ability and reliability have a direct influence on capability to perform the transport task is directly responsible for accomplishment of the city transport system tasks. In order to develop a model of means of transport serviceability there were determined significant states of the operational use process and there was made a division and reduction of the number of states in terms of the availability criterion. On this basis, an event model of the process of transport means operational use, and then a mathematical model of this process, were built with the assumption that its model is a homogenous Markov 's process X(t). Next, boundary values of availability coefficient for the distinguished availability levels of transport means used in the city transport system were determined for operational data obtained from a real city bus transport system. The discussed model for determination of transport means availability is an initial one, developed on the basis of a nine-state model of operational use. In further part of the paper, there will be developed a resultant model of transport means availability determination (semi-Markov 's sixteen-state model), being a component of a wider, decision model for creation and assessment of transport means availability.
