Solving the multi-criteria task of optimizing the processes of aircraft recycling

The domestic aviation fleet is awaiting a large-scale upgrade as part of the import substitution program, which creates a relatively new and urgent problem for Russian civil aviation in handling end-of-life aviation equipment. Currently, the dismantling and disposal of aircraft is carried out in fragments and haphazardly. There are no clear, scientifically based and legally fixed procedures. The uniqueness of aircraft design and operational features make the processes of their disassembly, recycling and disposal labor-intensive and unprofitable. At the same time, the growing demands on resource conservation and environmental protection force us to seek and implement environmentally sound procedures at the final stage of the aircraft lifecycle. The article presents the results of the development of the theoretical and methodological foundations of the industrial system for handling decommissioned aircraft. An algorithm for the reverse logistics of end-of-life aircraft is proposed. A methodology for assessing the recyclability of aircraft has been developed. The objective function of aircraft recycling efficiency is described, the value of which is determined by solving a multi-criteria task that considers economic, environmental, technical and social criteria. The values of individual and group criteria are substantiated. The proposed methodological framework will make it possible to carry out a technical and economic assessment of the effectiveness of procedures for handling end-of-life aviation equipment, choose the most rational approaches, minimize economic losses and environmental costs, and promote the development of innovative technologies for recycling aviation equipment
