ILIAS is an end-to-end solution and was initially designed for F-16’s; providing MRO organizations with tools to safeguard airworthiness, enable transparency, accountability and efficiency. The DCM (Defense Capability Management) is the ILIAS decision support environment and part of the ILIAS Defense Platform.

Over the past 25 years, the solution has been developed and improved in close cooperation with the MRO industry; resulting in a set of best practices regarding set-up, preparation, planning, control and execution of those programs. It evolved over time and provided a proven concept for DLM (Depot Level Maintenance) program execution.

The MRO Solution can load work packages before induction and provide the updated configuration data back to the customer. It offers tremendous transparency and visibility. The visibility of facts will help to discuss the scope of the contract and manage it during execution; explicitly capturing over & above’s as well as seek commitments for them. The ILIAS MRO Solution lowers costs and shortens down times considerably. Leaders can now have greater confidence in decisions and knowing their entire team operates off the same set of instructions and information.  This proven concept framework, based on experience and knowledge, is highly recognized by F-16 users and can be applied to any type of platform and complex MRO environment.


Configuration Management provides all the required functionalities to document, control and manage configuration changes during operational sustainment as well as Depot level Maintenance. During operations, a controlled configuration tracking is required to register changes and propagate it in the breakdown structure and to forecast work packages based on the various maintenance programs at any given moment in time. This is key to fully grasp the work load on an aircraft next to for instance an upgrade work package that needs to be executed at Depot Level. The business rules driven by the ILIAS Configuration Management can also be triggered by loading data from the Logistics Management System that is used to manage the day to day operation if this is not facilitated by ILIAS. All in all, total visibility of all work is the result before an aircraft is inducted.

The configuration of a fleet of weapon systems is built up according to specific layered hierarchies (trees) or ‘breakdown structures’.  The configuration management module uses three types of breakdown structures; each of them allows for an unlimited number of levels. This makes the software the unique solution for complex systems.

  • First, the equipment is described in a theoretical breakdown known as functional structure. This is the virtual representation of the weapon system or equipment (e.g. fuel pump function within the main engine within a helicopter).

  • Secondly, the ‘material structure’ is defined based on a specific function (e.g. the fuel pump) called the ‘applicability’. This is a particular type of equipment that can fulfil the specific function within a defined asset. For example, a fuel pump could be a type 1, or a type 2 version 3. By defining this relationship, conditional interchangeability is defined.

  • Thirdly, the software allows management of serialized and non-serialized components. The assets are uniquely identified by equipment type and serial number and built as a physical structure; all in compliance with restrictions and combinations specified in the theoretical and applicability structures. After which, the actual fleet becomes visible and manageable to provide total asset visibility.

By using well-developed Work Control Documents (WCD), our customers are able to improve workforce scheduling to create consistency as well as control the supply chain. Scheduling execution per phase, per aircraft area and per skillset, requires organizing many specialists to work simultaneously on the aircraft. Using this approach with up to ten specialists can be scheduled to work simultaneously during the depot maintenance or maintenance of the aircraft.

By consolidating all maintenance tasks per phase, per aircraft area and per skillset, the number of WCDs is reduced and a complete optimal depot maintenance schedule with clear milestones is created.


Technicians can select their assigned tasks on a mobile device and access corresponding steps from their job guide. Steps can then be checked off to generate real time keeping records at a high level of granularity. Supervisors will see actual progress that provides opportunities to immediately intervene if necessary. And maintainers are able to verify steps from any pre-loaded technical documentation.

ILIAS Guide Studio enables the user to author job guides and assures continuous improvement of execution, centrally managed.
