Abstract:

Aiming at the multiple projects’ selection of aerospace electronic modular products, a quantitative optimal evaluation method based on multi-layer fuzzy decision analysis is presented. A multi-layer optimal evaluation model is established. The multi-rank factors such as techniques, productization and economics are introduced, and their optimal aspects are determined. As evaluation factors of aerospace products are not easy to be quantified, both quantitative calculation and expert evaluation are taken into consideration for statistics. The weights of evaluation factors are allocated according to the focus of aerospace products, and economic and universal factors are highlighted. Through a case study, the method has successfully carried out quantitative optimal evaluation on multiple projects of functional modules, the result is consistent with the aerospace project selection. The evaluation method is simple, the result is distinct, and it conforms to the process of cognition. It is an effective and rapid evaluation method.
