| description | The purpose of this work is the theoretical substantiation and development of a practical
method for calculating the exchange fund of electrical equipment of an industrial enterprise. The
purpose is achieved through the use of separate methods of queuing theory if the flow of applications
for repairs and restoration are the simplest. It is confirmed by the results of statistical studies.
Therefore, for the mathematical description of the repair problem the authors use the scheme
Mm; Ms; n , which corresponds to the process of death and reproduction. As a criterion for
optimizing the exchange fund of electrical equipment it is proposed to use the zero probability waiting
for the replacement of a faulty electrical component with a working from the exchange fund. For the
case of the simplest flow of applications for service, the authors suggest to use the Peck and
Hazelwood tables, which significantly simplify the calculation of the exchange fund for known failure
rates and electrical equipment recoveries. For practical use of the proposed method, the authors have
developed convenient forms for presenting initial data for calculating the exchange fund, and it is
proposed to present the results of calculations in the form of several options for the optimal number of
electrical equipment in the exchange fund depending on the accepted level of zero expectation
probability, the number of elements from the exchange fund and their recovery time. The proposed
method will optimize the exchange fund of electrical equipment and reduce the cost of its formation. |
