Opis:: In this work, a method for assessment and control of availability of executive subsystem consisting of elementary subsystems of the type has been presented. The goal of the executive subsystem is to perform the assigned transport tasks over set routes, with a given frequency, according to a set schedule. A proper accomplishment of the transport task is possible only if the required number of technical objects (transport means) is prepared to perform the assigned task in a given time. Among many significant criteria used for assessment of a transport system operation there is one of special importance that is availability of the executive subsystem to perform the assigned tasks. Availability of the executive system to perform the assigned tasks depends on availability of particular technical objects (transport means) used in the system of transportation and their number. On the basis of the above statement, it can be said that control of the executive subsystem availability can be carried out both by selecting technical objects with the required availability and matching the required number of the objects which are to be used in the system in order to ensure proper accomplishment of the transport tasks. In this work there has been discussed a method for determination of the required availability of a single object as well as the required number of technical objects indispensable to perform appropriately the assigned transport task, on the basis of the transportation system availability assessment. Availability of the transportation system is determined on the basis of a mathematical model of the operation and maintenance process of technical objects, in the studied transportation system. Exemplary results have been presented on the basis of experimental data, obtained from the tests carried out in a real operation and maintenance system of transport means.

Opis:: The paper deals with an analysis and mathematical model of means of transport operation and maintenance. The considerations are based on a selected real transport means system - city bus transport system in a chosen agglomeration. The model has been built on the basis of a real city transport system involving realization of the process of operation and maintenance of means of transport. For this purpose, the process significant states and possible transitions between theses states have been determined. On this basis, an event model of means of transport operational use process was built, and next its mathematical model was made, with the assumption of its being the homogenous Markov 's model. Means of transport values of boundary probabilities for their being in the process particular states, were determined for data concerning their operational use. This serves as the basis for an analysis of the studied process of operational use. The presented Markov's model of the means of transport operational use process is the effect of accomplishmen of the first stage of the resultant model (semi-Markov's model) of operational use. The resultant model will be a part of a wide scale, decision model for creation and assessment of the transport system being ready for operation.

Opis:: W pracy przeanalizowano gotowość środków transportu eksploatowanych w wybranym rzeczywistym systemie transportu drogowego. Gotowość środków transportu w istotny sposób wpływa na możliwość realizacji zadań przewozowych i utrzymywana jest na odpowiednim poziomie w wyniku realizacji procesów w podsystemie logistycznym, wykonywanych na stanowiskach zajezdni (procesy obsługi, naprawy, diagnozowania i zaopatrzenia). Obiektem badań było przedsiębiorstwo transportowo-spedycyjne zajmujące się przewozem ładunków na terenie Unii Europejskiej, krajów skandynawskich i Rosji. Na podstawie literatury opracowano wzory opisujące gotowość badanych środków transportu oraz dla danych eksploatacyjnych wyznaczono jej wartości. Rezultaty badań stanowią podstawę do opracowania założeń do budowy i skonstruowania matematycznego modelu wyznaczania i oceny gotowości środków transportu drogowego.
In this article there is presented the availability of transport means in the selected system of road transportation. Availability of transport means has a significant influence on the capability of the transport task accomplishment and is maintained at a proper level due to realization of processes carried out within the logistic system on stands of a depot (servicing, repairing, diagnosing and supplying processes). The research object is a transportation-shipping company carrying loads on the territory of the European Union, Scandinavian countries and Russia. Based on the literature developed models which describing the availability of respondents means of transport for operational data and determined its value. The results of tests provide basis for elaboration of assumptions to build a mathematical model of availability of road transport means.
