"VALORIE (VALidate Operations to Reduce Impact on Environment) aims to support Systems for Green Operations ITD in validation of novel, environment-aware practices of aircraft take-off and cruise against a wide spectrum of available operational expertise. The modelling of a broader operational environment that includes ATC, airports, CFMU, etc. can be well done by advanced simulation and gaming techniques. Moreover, there is a mature methodology available to do air transport industry-related validation, namely E-OCVM. However, validation is usually conducted by a group of experts coming from the same operator. This approach (governed by the fact that gathering experts from different employers is a challenging task) prevents the heterogeneity that would be by implicitly beneficial for the outcome validation. Experts doing their daily work in the same corporate environment are trained for the same company processes. This leads to similar approach to the validation subject and results in similar opinions at the end.VALORIE is a project that puts emphasis on increased heterogenity of the expert group validating operational scenarios provided by SGO. This approach will result in an added value generated by the synergy of opinions coming from experts working in the same field of air transport industry but being aware of different company practices and policies."
