Abstract


The research focuses on assessing the economic efficiency of implementing a jigless manufacturing preparation method in light aircraft production. The relevance of the research is determined by the need to reduce costs and lead times for manufacturing preparation when developing new aircraft types, which is especially important for small-batch aircraft production. Traditional template-based manufacturing preparation methods require significant expenditures for the design and production of assembly tooling, which reduces the economic efficiency of production processes. The use of digital product models and coordinate-based alignment technologies creates prerequisites for the transition to jigless manufacturing preparation methods. The aim of the study is to develop a methodology for assessing the economic efficiency of implementing a jigless manufacturing preparation method for light aircraft production. To achieve this aim, the following tasks were addressed: analyzing of the cost structure of manufacturing preparation; development of a cost model for implementing the jigless manufacturing preparation method; identification of the main sources of economic benefits; and development of an algorithm for calculating integrated indicators of economic efficiency. The research methodology is based on econometric modeling, analysis of aircraft manufacturing processes, and the application of discounted cash flow methods for investment evaluation. The results of the study provide a formalized methodology for assessing the economic efficiency of implementing jigless manufacturing preparation technologies. The proposed methodology makes it possible to quantitatively evaluate the economic effects obtained through the reduction of assembly tooling manufacturing costs, the decrease in labor intensity of manufacturing preparation processes, and the improvement of flexibility in manufacturing systems. The conclusions confirm that the implementation of a jigless manufacturing preparation method is economically feasible and contributes to reducing manufacturing preparation costs and improving the efficiency of resource utilization in light aircraft production. The scientific novelty of the study lies in the development of a formalized methodology for the economic evaluation of jigless manufacturing preparation technologies, which considers the structure of assembly tooling manufacturing costs, the labor intensity of manufacturing preparation processes, and the influence of production volume on the economic feasibility of implementing jigless technologies. The practical significance of the obtained results lies in the possibility of using the proposed methodology for the techno-economic justification of implementing jigless manufacturing preparation technologies at aircraft manufacturing enterprises.
