Method of time distribution for repair of radio electronic means with multiple defects

Abstract

The article proposes a method of redistribution of time between stages of diagnostics and complete elimination of defects of radio-electronic means in the conditions of the repairing service. The method minimizes the average recovery time in the process of elimination of multiple defects which result from accidental or combat damage. It consists in a comprehensive consideration of the components of the repair process after preliminary identification of defects at the location of damage and in the estimation of the expected multiplicity of defects. A block diagram of the algorithm for solving of this problem is proposed. The algorithm differs from the known analogs by the account for the probability of correct diagnosis and the metrological reliability of the used measuring equipment. The application of the method at given conditions allows us to quantify the time of implementation of each stage of recovery and to reasonably recommend a redistribution of efforts to minimize the average recovery time of electronic devices with multiple defects. An example of the application of method, illustrating the influence of managed variables on the efficiency of the method, is presented. The use of the obtained results allows one to increase the capability of military repairing service in the recovery of equipment with weak and medium combat damages, either in the field conditions, or at the points of maintenance and repair service. The proposed method is recommended for implementation in the software for maintenance of the REMs of modular type.
