A comprehensive approach to the structural synthesis and evaluation of engineering solutions in the design of transportation and technological systems

Abstract

The article deals with a complex application for the structural synthesis and parametric optimization of the design of transportation and technological systems and evaluation of innovative engineering solutions based on advanced morphological approach. The approach is based on the multicriterion principles, cluster analysis, and the theory of sets. The article provides examples of application of the proposed approach to the selection of the process of manufacturing of long hollow shafts of gas turbine engines from heat-resistant alloys and steels under isothermal conditions, determination of the optimal values of the resonant transducer for reducing longitudinal vibrations of a mechanical system, and synthesis of transportation systems. The application of the advanced morphological approach enables the refining and ordering of the structuring of the problems to be solved. The degree of the validity of the adopted solution is considerably increased by applying to every variant of the selected structure the method of parametric optimization of the LPS search implemented by a separate algorithm, which enables enhancement of the quality (technological level) of the technical systems under design.
