Armac

What Armac does

Armac Systems is an Ireland-based software company specializing in MRO (Maintenance, Repair, and Overhaul) inventory optimization for commercial airlines and independent MRO providers. Its flagship platform, RIOsys, is a purpose-built decision support system that applies advanced mathematical optimization, statistical forecasting, simulation, and machine learning to determine optimal spare parts inventory levels under the aviation-specific 'Repair to Reuse' planning model. The platform integrates natively with customer ERP systems (notably SAP), runs on Amazon Web Services, and combines transactional data, codified planner expertise, and probabilistic modeling into a unified inventory planning environment, with reported outcomes of up to 40% inventory investment reduction and up to 20% service level improvement.

The company was carved out of SR Technics' Component Services division via a management buyout in September 2020, led by CEO Micheál Armstrong and Mark Stacey, and has since served enterprise clients including Iberia Maintenance, Cathay Pacific Airways, Finnair, and SR Technics. RIOsys is sold through direct enterprise sales engagements involving competitive RFP processes, multi-year contracts (e.g., a five-year agreement with Iberia), on-site implementation, and ongoing customer success management. Revenue is generated through software licensing/subscriptions paired with consulting and implementation services under a CXO-led customer success model, with no public pricing disclosed. Armac also sells the Inventory Planning Capability Framework (IPCF), a methodology blueprint addressing strategy, people, processes, systems, and financial planning for MRO inventory management.

Core offering

Armac Systems develops and licenses the RIOsys software platform — a purpose-built inventory optimization and decision support system for aviation Maintenance, Repair, and Overhaul (MRO) operations. The platform combines transactional ERP data, expert planner knowledge, and advanced mathematical optimization, simulation, and machine learning models to calculate optimal spare parts inventory levels across rotable, consumable, and engine shop materials. Complementing the software is the Inventory Planning Capability Framework (IPCF) methodology, together with implementation and customer success services delivered through direct enterprise engagements.

Product overview

Armac Systems offers a unified MRO inventory optimization platform centered on RIOsys software, which consists of integrated modules including Decision Support (DSS), Inventory Planner's Workbench, Knowledge Base, and Advanced Analytics. Complementing the software is the Inventory Planning Capability Framework (IPCF), a methodology that provides a detailed blueprint for addressing aviation inventory challenges. The platform helps airlines and MROs calculate optimal inventory levels, incorporate expert planner knowledge, and apply advanced mathematical models to maximize availability at lowest cost.

• SR Technicsformer parent company (now exited)Strategic or Co-development Partner · 14 September 2020SR Technics was Armac Systems' parent company until September 2020, when Armac's management (Micheál Armstrong and Mark Stacey) completed a management buyout. Over the preceding decade, RIOsys was developed and refined in close collaboration with SR Technics' Component Services. SR Technics CEO Jean-Marc Lenz and CFO Matthias Düllmann supported the MBO. SR Technics had been an integrated component services provider; as that business ramped down, Armac was relaunched as a separate entity. SR Technics continues as a customer.
