飞翔的战国

“言行不一”的航企 2011年6月,230家国际航空公司的代表齐聚新加坡,参加国际航空运输协会（IATA）年会。已经超过110美元／桶的国际油价,为这次盛会蒙上了重重的阴影。按照业界测算,单桶油价每涨1美元,每年就会为全球航空业带来16亿美元的额外负担。而IATA的预测是,2011年的单桶油价将比20l0年高出30美元。     

Improving the IATA delay data coding system for enhanced data analytics

Aviation delays inconvenience travelers and result in financial losses for stakeholders. Without complex data pre-processing, delay data collected by the existing IATA delay coding system are inadequate to support advanced delay analytics, e.g. large-scale delay propagation tracing in an airline network. Consequently, we developed three new coding schemes aiming at improving the current IATA system. These schemes were tested with specific analysis tasks using simulated delay data and were benchmarked against the IATA system. It was found that a coding scheme with a well-designed reporting style can facilitate automated data analytics and data mining, and an improved grouping of delay codes can minimise potential confusion at the data entry and recording stages.
