Abstract
The paper emphasizes the basic attitudes of complex technical system maintenance programming. Particularly it is performed an analysis and a selection of strategies for condition-based maintenance. The assessment of the established maintenance program varieties effectiveness was carried out by comparison with their basic indicators of effectiveness (for corrective and preventive maintenance).
Highlights
The disadvantages of policies and strategies for preventive maintenance, in the broad areas of practice in recent years, initiated a trend of a maintenance planning based on its state system the process of exploitation
Preventive maintenance policy based on the execution of planned activities at certain intervals, regardless of the component parts technical condition and or the system, does not provide enough action and the link between changes in the technical conditions and process of exploitation
By planning of works and the periodicity of their execution, depending on the technical condition and or the system obtained on the basis of diagnosis, is provided by the condition-based maintenance strategy
Summary
The disadvantages of policies and strategies for preventive maintenance, in the broad areas of practice in recent years, initiated a trend of a maintenance planning based on its state system the process of exploitation (condition-based maintenance). Preventive maintenance policy based on the execution of planned activities at certain intervals, regardless of the component parts technical condition and or the system, does not provide enough action and the link between changes in the technical conditions and process of exploitation. Technical relationship provides the possibility of applying a large number of condition-based maintenance strategies According to research, these strategies can be classified into two groups: maintenance according to the state with the parameter control, and maintenance according to the state with the confidence level control. Maintenance according to the state with the confidence level control is to collect, process and analyze data on the reliability of components and/or systems and develop the necessary decisions on planned maintenance activities on the replacement or repair of the system component parts
