Multiple criteria decision analysis techniques in aircraft design and evaluation processes

摘要: Air transportation systems are complex, interdisciplinary integrated systems, because there large numbers of components with different characteristics. It is challenging to assess new technology in such as air systems. The focus this research one element complex systems: aircraft. success an aircraft no longer dominated by economic criteria. Several other criteria, environmental aspects and level comfort, need be taken into consideration. Therefore, design evaluation typical multi-criteria decision problems prudently conducted. One solution apply Multi-Criteria Decision Analysis (MCDA) techniques. The goal investigate how MCDA techniques can applied order provide better aiding for stakeholders First, advanced approach effectively select the most appropriate analysis method a given making problem formulated presented research. This selection implemented intelligent support system developed. Second, proposed assessing uncertainties propagated process. uncertainty assessment consists four steps: characterization, analysis, local sensitivity global analysis. novel used aggregate input data from tools fidelity levels capable propagating chain. Third, two proofs concept conducted demonstrate effectiveness applying processes. In efficiently related subjective preference information process, surrogate models criteria terms weighting factors Furthermore, soft quantification process permits synergy hard technical additional
