Abstract
The importance of system reliability within military logistics should be considered in terms of the ability to ensure the readiness of all available resources, e.g., means of transport, which are necessary during the realization of operational tasks. A special role is played by technical security, which enables the performance of all the specific tasks by the realization of the process supporting the subsystem in the area of providing the necessary assemblies, subassemblies and spare parts. The objective of the work was to define reliability in relation to technical means of transport and to illustrate an original solution leading to the determination of the expected fitness time of the available vehicle fleet, using the example of a selected military unit. The GNU Octave software—designed to conduct, among other things, advanced numerical computations—was used for the study. The daily operational mileage for a selected group of means of transport and the moments of failures were recorded during the tests, for the period from 31 December 2013 until 30 June 2015. The conducted analysis enabled the determination of the fundamental reliability indicators. The presented model has been supported with numerical examples, along with the interpretation of the obtained results.

Summary
The basic components of a logistics system’s potential include the technical measures enabling the storage, displacement and handling of cargo units, integrated computer networks and decision-making services managing the physical movement of goods. Due to the structure of the technical objects, the following infrastructural elements can be distinguished: Linear, understood as a grid of specified strips of land, intended for parking or traffic of means of transport; Point, comprising objects intended for the stationary handling of cargo and means of transport; Informative, consisting of media, telecommunication lines and measures ensuring data transfer [5,6,7,8,9]. The reliability of technical objects, in technical terms, shall be understood as a set of properties determining the readiness of an object and impacting such readiness: Operability—the ability of an object to maintain or restore, under specific operating conditions, a state enabling the execution of required functions; Appl.
