A key element of exploitation processes constitutes maintenance operations and tasks. While being conducted in the proper way, they have a crucial effect on achieving the assumed by aircraft designer and operator goals. Properly conducted maintenance operations allow to meet all the technical objects readiness requirements as well as to achieve desired acceptable risk level. Maintenance system effectiveness might be generally a crucial task for company or entity responsible for the maintenance. In this context, particularly relevant become technical object maintenance procedures and tasks developed by their manufacturers. Experience of the article authors quite early shows the need of the maintenance programmes modification. Aircraft manufacturers usually are not so eager to develop and implement maintenance programme modifications. Presented situation is very much the case in aviation transport. This was the reason why authors of this article decided to prepare and develop this elaboration which might constitute the assistance and supports complex technical objects users in maintenance decision. The main purpose of this article is to present maintenance decisions’ supporting method for the aircraft operators. This article provides guidelines which include a description of risk in the context of aviation maintenance and introduction of some methodologies, tools and criteria that support identification, analysis and evaluation of risk. Authors included idea, how the aircraft preventive maintenance could be used to mitigate aircraft failure risk during flight operations. It also shows how to adopt and develop effective maintenance program using tools for adequate risk analysis, optimal interval assignments, and selection of the most effective maintenance task. Authors presented methodology and described steps of the logic diagram analysis for the aircraft systems and their components, in order to manage and adopt aircraft maintenance program to fulfil aircraft airworthiness requirements and operational availability. The whole methodology was described on the basis of the F 16 aircraft maintenance system and with reference to the maintenance data. This article might also constitute an introduction to the aircraft maintenance programme development method.

W referacie opisano system diagnostyczny dla kotłów K3-K6 zintegrowany z bazą danych ekonomicznych zawierajaca m.in. koszty usuwania nieszczelności rur powierzchni ogrzewalnych oraz wartość produkcji. Rezultatem integracji wyników badań diagnostycznych, analizy awaryjności, warunków pracy oraz wybranych danych ekonomicznych będzie podejście do utrzymania stanu technicznego powierzchni ogrzewalnych kotłów według strategii Risk Base Maintenance (RBM).

Przedstawiono koncepcję metod RBM (Risk Based Maintenance) - zarządzania obsługiwaniem warunkowanego ryzykiem. Wskazano sposoby zastosowania tej koncepcji w procedurach decyzyjnych związanych z obsługiwaniem pojazdów szynowych. Podano sposób wykorzystania ryzyka do ograniczenia obszaru rozwiązania dopuszczalnego w problemie decyzyjnym. Przedstawiono aplikację komputerową do generowania optymalnej struktury cyklu obsług elementów pojazdów szynowych.

We recall the idea of Risk Based Maintenance methods and introduce different ways of use of this conception within decision procedures for rail vehicles maintenance. Moreover, the way of use of risk assessment for the restriction of the area of feasible solutions in decision problems is discussed. The computer application for determining the optimal cycle structure of rail vehicles maintenance is also shown.
