Abstract
In systems of means of transport operation in order to achieve appropriate completion of assigned transportation tasks it is necessary to maintain a required number of means of transport in the state of availability for carrying out of transportation task (roadworthy and stocked). In general, the processes of rendering vehicles roadworthy are connected to supplying them with fuel and operational materials, carrying out services and repairs, condition diagnostics. In the analyzed system of transport means operation, the processes are carried out in serviceability assurance subsystem SAS. In complex operation systems, the processes of rendering technical objects roadworthy are carried out at specifically designed technical infrastructure posts. The possibility of carrying out the assigned service and repair tasks depends on the availability and the number of such posts. The article presents the method of defining the operational availability and the number of technical infrastructure posts required for appropriate functioning of assigned service and repair task. Then typical calculation results are presented in charts prepared on the basis of data obtained from tests at existing transport means operation system.

In systems of means of transport operation in order to achieve appropriate completion of assigned transportation tasks it is necessary to maintain a required number of means of transport in the state of availability for carrying out of transportation task
The processes of rendering vehicles roadworthy are connected to supplying them with fuel and operational materials, carrying out services and repairs, condition diagnostics, transporting damaged technical objects, rearming in order to complete the assigned task
On the basis of the method presented in the paper, it is possible to select the minimum required number and availability of posts of serviceability assurance subsystem so that the assigned service and repair tasks are carried out properly
Summary
In systems of means of transport operation in order to achieve appropriate completion of assigned transportation tasks it is necessary to maintain a required number of means of transport in the state of availability for carrying out of transportation task (roadworthy and stocked). The processes of rendering vehicles roadworthy are connected to supplying them with fuel and operational materials, carrying out services and repairs, condition diagnostics, transporting damaged technical objects, rearming in order to complete the assigned task. The problem of control of the processes carried out at serviceability assurance subsystems from the point of view of evaluation criteria such as reliability and availability is discussed in numerous scientific publications [1, 4]. The objective of this paper is to work out a method of determining the number and availability of serviceability assurance subsystem post at such a level that would ensure appropriate carrying out of service and repair tasks assigned for to be carried out at such posts
