The article presents the method for control of availability of executive subsystem with the threshold structure, consisting of elementary subsystems of the type . The whole of the consideration was presented using the example of a chosen authentic system of the operation and maintenance of transport means. The basic objective of the operation of transport systems is fulfilling the transportation needs as a result of the carrying out of transport on particular routes. The effectiveness of the operation of transport system depends on the possibility of correct carrying out of the assigned transport task. 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. The presented method consists of determining and comparison of the values of the required and actual availability of the executive subsystem. The article deals with the way of determining the required availability of an individual technical object (means of transport) as well as the required number of technical objects used in the system, in order for the obtained value of the availability of the executive subsystem to exceed the value of the required availability determined by the parameters of transport task. The availability of the individual technical object was defined on the basis of a constructed mathematical model of operation and maintenance process realized in the tested transport 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.
