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.”

Finnair Airmac Systems

Armac supports Finnair to optimize their Rotable Component Availability Sourcing Strategy


Armac releases Finnair case study demonstrating how it’s RIOsys software has been successfully applied to  optimize Finnair’s A320 family component sourcing strategy.


As a consequence of the COVID-19 global pandemic there has been a significant downturn in the aviation sector. While air travel will certainly recover, the extent and nature of the recovery is uncertain.  Like many other airlines, Finnair will have surplus capacity and surplus aircraft for the short to medium term.  In particular Finnair identified that there were surplus aircraft within the main short-haul fleet of A320 aircraft.  In the current flooded marketplace components from teardown aircraft have reduced value, so a simple strategy of tear down and sell components would be a sub-optimal approach.


Armac Systems Announces Management Buyout

September 14, 2020

Armac Systems is pleased to announce the management buyout from SR TechnicsOver the past decade, the powerful inventory planning, decision support and optimization capabilities of Armac’s RIOsys software were developed and refined in close collaboration with SR Technics’ Component Services. As Integrated Component Services is now ramping down, there is no longer a critical need for the services that Armac Systems provides to be retained as an in-house capability. In this regard, Armac Systems is relaunching as a separate entity.

Micheál Armstrong and Mark Stacey, the heads of Armac Systems, have been strong supporters of the buyout, as has SR Technics Chief Executive Officer and Armac Systems exiting board member Jean-Marc Lenz. With a platform that optimizes the supply chain right from demand forecasting through to provisioning and deployment, the company is well positioned to integrate with its customers current system landscape.   Additionally, its proprietary software, RIOsys, will form a core component of the supply chain digital transformation complimenting new digital technologies such as predictive analytics and blockchain.

Commenting on the MBO, CEO of Armac Systems, Micheál Armstrong said

“In close collaboration with our customers, Mark and I have dedicated ourselves for over a decade to making RIOsys the best of breed solution for MRO inventory optimization.  We are very excited to lead Armac into this new phase and we see a real opportunity to help our customers in a time of great challenge and change for the industry.  Although there will certainly be a paradigm shift we strongly believe that aviation will have a bright future and digitalization of the supply chain will form part of that future.  Armac’s RIOsys software sits at the heart of planning this new digital supply chain landscape and we look forward to playing our part to support our customers enable the revival.”

“Armac Systems offers a best-of-breed solution in its class,” said Matthias Düllmann, Chief Financial Officer at SR Technics and exiting member of the board at Armac Systems. “We are grateful for the successful partnership we have had with Armac Systems during the past 6 years, during which we jointly developed a solution that enables data-driven decisions which are of vital importance for every MRO business.”
