The problem of developing mathematical methods for improving the efficiency of the organization of repair and maintenance work requires the formulation of general principles for determining their actual state in the process of operation.
In order to increase the efficiency of the use of machines and electrical equipment of technological systems, the optimization of restoration works based on the results of diagnostics is necessary, which will ensure their high trouble-free operation and durability of all elements of the system.
The main task is to determine the residual resource, which makes it possible to reduce the complexity and cost of the work that is carried out during ongoing repairs, installed only when necessary; set the timing (periodicity) of diagnosis.
To optimize the characteristics of technological systems and diagnostic tools used the technical and economic criterion of the minimum unit costs of the technological system as a whole. In this case, take into account the features of the elements of the system and the diagnostic method, which affects the total unit costs.
Regarding diagnosis, the total costs associated with the use of diagnostic tools, the costs of their production and expenses caused by the error of diagnosis.
Management of the technical condition of technological systems based on determining the optimal residual life of each element allows you to plan repair and restoration work using the principles of system analysis. At the same time, it is advisable to simultaneously repair the elements of the production line, and therefore the costs will be distributed between them and thereby the cost of repair of each unit will be reduced.
Compatible repair of technological installations, the terms and volumes of which are determined by comparing the intervals of the residual life of all components of the technological line, will be more cost-effective than individual repairs of individual machines.
The estimates obtained with this method, in particular, can be used in the planning of repair and maintenance work of technological systems.
Key words: technological line, failure, diagnosis, residual resource, technical and economic criterion, target function
