The paper describes issues related to reliability of military vehicles based on recorded operational events. Seeking the quantification of reliability for exploiting vehicles in military units, an extensive analysis of factors shaping the reliability level was made, taking into consideration all phases of military vehicles existence and a peculiar character of the exploitation process of military vehicles. The importance of reliability research in the decision process optimization was emphasized, controlling the efficiency and availability of the exploitation system.

The subjects of this publication are the issue of reliability studies of military vehicles, the determination of reliability indicators of selected groups of vehicles, and the adoption of complex models of operation for analysis based on recorded operational events. Numerical simulations of operating states were performed to verify the models and the adopted reliability indicators. It has been shown that it is possible to use the obtained results of research in the economic efficiency-oriented military vehicle management system in order to minimize structural surpluses and increase the efficiency of the land technology equipment park.

The article discusses the essence of dependability for the military vehicles, the knowledge of which ensures success in the mission and provides an appropriate level of the crew safety while  executing combat tasks. The paper also includes an analysis of factors affecting the dependability for the military vehicles.

Reliability studies in the operation of military vehicles are not carried out extensively. This is due to the guidelines of superiors regarding the keeping of operational records in military units. As a result, this work attempts to determine the reliability of military vehicles. This work includes reliability tests of military vehicles operated in military units in the second phase of operation, i.e. in the operation interval, where the extent of change in the intensity of damage is the least in the function of mileage. The study used a sample of 37 vehicles for which all operational events relevant to reliability determination were recorded during a two-year observation period. Using recorded operational data, an empirical reliability function of the vehicles included in the test sample was determined. Based on reliability tests of the reliability function as a function of mileage to damage, they show that second-phase vehicles used in military units have a logarithmic distribution of reliability as a function of mileage.

This paper focuses on the determination of effectiveness of the implemented system ZWSI RON in an analysis of the vehicles operation process in the army. With this end in view, a questionnaire-based diagnostic survey was conducted on staff members of the technical services of the Polish Army logistics units. The survey research results analysis shows that 90% of the respondents do not use the basic PM (Plant Maintenance) module of the ZWSI RON system to manage the operation of military vehicles. One should consider a modification of the mentioned system, i.e. creating new modules and new relations between individual modules of the system, using SAP system structure solutions.
