Four integrated, yet independent systems provide a complete solution

The Engine Reliability System determines reliability parameters by engine type. The system evaluates the premature removal rate (PRR) of engines in a given fleet, as well as other critical performance indicators, such as Weibull slope and characteristic life. Because requirements for engine maintenance resources are dictated by these parameters, more accurate and timely information will lead to better decisions.

The Engine Removal Forecast determines the removal volume of any engine-type fleet for a specific time period. In addition, the system calculates other removal characteristic indicators - such as probability of survival until the next scheduled removal and expected flying time until the next removal. Precise forecasts are essential for allocating resources, optimizing your maintenance operations, and Lean MRO.

The Engine Life Optimizer specifies the most cost-effective life-limited parts replacement policy for your engines. Replacement decisions for life-limited parts, such as discs, are vital to engine maintenance planning because selection practices directly influence engine lifetime. With ELO, you can reduce engine maintenance cost per flying hour by optimizing engine lifetimes. ELO also includes a built-in inventory control system to track the availability of life-limited parts.

The Spare Engine Planning System not only determines the number of spare engines needed to support your air operations, but also specifies the proper allocation of engines throughout your operation network. In addition, you can use SEPS to decide how many engines to stock at the base and maintenance stations for a given number of spares, and what protection levels and fill rates can be expected at different stations for various allocation scenarios.

SEPS uses the state-of-the-art multi-echelon inventory model for repairable/rotable parts. Please click here to visit the website for our work in materials management for repairable parts.

You can work in Microsoft Excel for data entry and editing. This substantially eases data handling. In addition, often the data required by AEMPS exists in MS Excel from various sources. As such, data-entry duplication is avoided by using the facilities of MS Excel.


AEMPS output reports are also exported to, and transmitted in, MS Excel. That way, custom-built reports can be developed. Also, further analyses of AEMPS output reports, including creating graphical charts, and/or making the results available for other applications, can be done easily because of this data export facility to MS Excel.
