To reduce disruption impacts on customers, All Nippon Airways (ANA) and Hitachi, Ltd. (Hitachi), in collaboration with Hitachi Consulting Co., Ltd. (Hitachi Consulting), launched a system that automatically and rapidly generates optimized flight schedule revisions during disruptions affecting ANA’s domestic flight operations. This system was jointly developed by combining ANA’s operational expertise with Hitachi’s technological capabilities. This is the first time a Japanese airline has implemented such a system.
The system dynamically collects and analyzes large amounts of data, including aircraft operation schedules, maintenance plans, crew schedules and various airport conditions, to autonomously generate multiple revised schedule proposals. It intelligently adapts to real-time changes, including modifications to maintenance plans, airport or runway closures and consecutive irregular events across multiple airports. ANA’s operations staff can then swiftly review and select the most effective option, significantly reducing decision times and improving operational performance.
Previously, ANA relied heavily on the expertise of seasoned operations staff, which created challenges in both human resource development and the time required to formulate optimal schedule revisions that consider complex conditions within a limited timeframe. Therefore, innovation in operation management was needed.

Recognizing these challenges, ANA, Hitachi and Hitachi Consulting began developing the system in 20191. Extensive trials confirmed that the system’s proposals match the quality of schedules produced by highly experienced operations staff while reducing work time by several hours, especially during large-scale disruptions. For example, in scenarios where typhoons severely disrupted flight operations, veteran ANA staff with more than a decade of experience previously spent entire nights manually adjusting schedules to minimize impact.
With the implementation of this new system, we can now:
-Reduce the time needed to consider revisions by up to 70%.
-Respond flexibly and repeatedly to changes in weather forecasts, such as typhoon paths and speeds.
-Relieve the mental stress on operations staff who are pressured to quickly create and decide on schedule revisions.
-Improve flight stability by allowing for the rapid comparison of multiple revision options.
These benefits are expected to enable faster communication to our customers, which will in turn lead to an enhanced customer experience.
Amid the global push for digital technology in the aviation industry, this system boasts exceptional accuracy in two key areas: its versatility to automate solutions for any disruption, from major events to daily issues, and the comprehensiveness to replicate the operational quality ANA has honed in a challenging environment like Japan, with its frequent typhoons and complex flight paths.
ANA continues to drive digital transformation by integrating advanced technologies with human expertise, striving to set new global standards for operational excellence. For more information on this system and ANA’s flights, please visit the ANA website.
日立 will plan to expand this system as the Lumada2 solutions. The initiative will extend capabilities to ANA‘s international operations and other airlines worldwide, supporting critical social infrastructure. Then we aim to improve the productivity of frontline workers and enhance people’s well-being.
