Cathay Pacific Airways successfully implements Armac’s inventory optimization solution.

Hong Kong, 24 July 2023

Cathay Pacific Airways, one of the world largest 5 star airlines and the Hong Kong-based international carrier, has successfully implemented Armac’s “RIOsys” inventory optimization software to optimize its material planning for aircraft maintenance.

Digital Innovation and Material Planning is at the core of Cathay’s strategy to maximise its efficiency and aircraft availability. In 2022 Cathay launched a project to leverage its maintenance data to enhance decision making, targeting cost savings and improving aircraft dispatch reliability.  This search led Cathay to Armac Systems.  Following a competitive RFP, having reviewed and tested Armac’s capabilities, Cathay decided to implement Armac’s RIOsys inventory optimisation solution.

“Armac really impressed us with their understanding of the unique challenges we face as an airline.  Planning aircraft maintenance inventory is a complex undertaking with a diversity of supply and demand models requires a unique approach,”

commented Philippe Christol, Head of Inventory Management at Cathay. 

He went on to say, “As part of the selection and evaluation process Armac were able to model our operation and advise on strategic and daily tactical decisions to optimise our material supply performance. The fit was perfect for our business and we have already achieved significant measurable benefits and identified considerable further potential.”

The project was delivered on budget and on schedule, within an ambitious six-month timescale.  Remarking on the project, Armac’s CEO Micheál Armstrong acknowledged the contribution of Cathay’s Material team to the on-time delivery of the project.

“The Cathay team had to implement our software and continue to run their operation.  It takes the commitment and expertise of both parties to implement and adopt an inventory optimisation solution.  It was a great pleasure to work with the Cathay Materials team and both parties have truly learned from the experience, as is always the case with successful collaborations.”

Armstrong went on to say, “We appreciate Cathay’s trust and we look forward to our continued collaboration to deepen the adoption of our solution within their wider process roadmap and to deliver value supporting asset optimisation, repair cost management, pool / VMI scoping and the broader inventory planning landscape.”

Commenting further on Armac’s ongoing support Philippe Christol noted

“Another key aspect, which is not to be overlooked, is Armac’s Customer centric approach: even after full implementation of the system, they are continuously assisting us and they continue to implement improvements to the system to meet our future needs.”
