Abstract:Due to the multiple elements coupling and complex process of technology readiness assessment (TRA), system engineering methods are applied on TRA. Firstly, the mapping relationship of ‘V’ model and technology readiness levels are constructed, then TRA is multi-decomposed by Hall three-dimensional structure and Wuli-Shili-Renli method, and the relationship of technology readiness levels and technology risk are established. Finally, based on technology states, integration states, and environment states, the TRA inference rules are given, and TRA Hall for Workshop of Meta-Synthetic Engineering is presented by fusing above-mentioned methods. The certain UAV TRA practice has demonstrated the validity, and extended to other equipment.
