CONCEPTUAL FOUNDATIONS FOR DEVELOPMENT OF PROGRAMS TO PROVIDE REPAIRABILITY OF COMPLEX TECHNICAL SYSTEMS
Keywords:complex technical system, reliability, maintainability, efficiency, product, maintenance and repair, technical solution, maintainability program, restoration
The article proposes the conceptual basis for the development of programs to ensure the maintainability of complex technical systems (СTS). The importance and urgency of the problem of ensuring maintainability for modern STS is considered. It is shown that the reliability program and other documents do not pay due attention to the justification of maintainability at the stages of development and production of СTS. The necessity in substantiation of requirements to this property taking into account three main aspects is considered: technical, economic and organizational. The classification of maintainability indicators and the main groups of factors influencing them is given.
It is shown that the stage of research and development work is the main stage of СTS development, which should ensure compliance with the achieved level of maintainability of СTS, which is developed to regulatory requirements; at the same stage, all the main weak elements of the structure must be identified, the main causes of failures must be established. Measures taken at this stage to improve maintainability should take into account and be interrelated with both the manufacturing technology and the strategy of maintenance and repair.
According to the results - a modern approach to the problems of improving the maintainability of СTS, as one of the areas of improving the efficiency of operation. The modern approach to the problems of СTS maintainability is defined and the tasks for its solution are specified on the basis of the analysis of the solution of this problem in the USA and other leading countries of the world.
The main directions of development of the plan and the program of maintenance of serviceability of СTS at their development and production are formulated. It is shown that the development of the plan and program to ensure the maintainability of СTS will allow to assess the level of maintainability from the moment of approval of the technical task to the moment of serial production. At the same time, it is emphasized the need to take into account that the consideration of the requirements for maintainability, laid down in the program, should become part of any project, as an element of the СTS development program.
