Aerospace Instrument-Making Annotation << Back MULTI-CRITERIA METHOD FOR CALCULATING A SPTA PACKAGE FOR THE AVIATION RADAR COMPLEX B.E. Pankovsky, S.N. Polesskiy The disadvantages of the methodology for calculating the set of spare parts, tools and accessories (SPTA). A multi-criteria methodology for calculating a local package SPTA based on the convolution method has been developed that allows simultaneous use of several optimization criteria (weight, volume, cost). Based on the convolution method, which allows to reduce the multicriterial task to a scalar one. To check the effectiveness of the developed methodology, the calculation of the local package SPTA for the aviation radar complex was carried out using the current one-parameter and developed multi-criteria techniques. The weight and size of the required spare parts kit was used as limitations. On the basis of the results obtained, an analysis was conducted of the effectiveness of the developed methodology. Keywords: spare parts, tools and accessories, reliability, redundancy, multi-criteria method, sufficiency indicator. DOI: 10.25791/aviakosmos.10.2019.928 Contacts: - Pp. 22-30.
