Maintainability

The ASENT Maintainability toolkit has been optimized to reduce data entry and maximize the use of existing reliability data to help you efficiently manage the maintainability analysis process. All necessary tools are included to assist in your analysis. The product tree structure and reliability prediction data is readily available in ASENT’s Maintainability toolkit, but you can quickly and easily add covers or other hardware often excluded from reliability predictions.

Both Corrective and Preventive Maintenance analyses are supported. ASENT calculates maintenance times (both mean and maximum, e.g., MTTR and MMaxCT) and outputs the result in both minutes and hours.

Organizational, intermediate, and depot levels of repair are fully supported for procedures II and V of MIL-HDBK-472. The tool’s powerful “what-if” mode instantly models the impact of various design and maintenance tradeoffs in real time.

ASENT’s built-in task libraries (MIL-HDBK-472 and RADC-TR-84-165) greatly reduce the time spent entering data. Also, since replacement tasks are often the same as remove tasks, only listed in reverse order, ASENT allows you to enter these with a single click of the mouse.

The tasks are then automatically entered and the appropriate task times are pulled from ASENT’s built-in task time libraries. When you combine this information with customizable Task Libraries, and the ability to enter Judgments as difficulty factors for working in hard-to-reach or adverse conditions, you get a powerful combination of maintenance planning tools.

ASENT provides you the capability to generate groups of tasks, detailed at a lower level and used as a single line item at higher levels. This prevents your documentation from becoming unwieldy. For example, a task group could represent an engine repair, which contains many individual tasks. This task group could be used on many different predictions, but if changes are needed, you only need to modify the engine repair task group in one location and everything else is now up-to-date.

Inherent, achieved, and operational availability are calculated as part of the analysis and are prominently displayed, along with other analysis results on the prediction results screen. With ASENT, the analysis results are consolidated on one easy-to-read page, so the affect on your system can be quickly determined.

The Maintainability tool comes with an extensive suite of reports. ASENT’s comprehensive reporting allows you to quickly slice the data, so that you can view just the information you want. The convenient Excel format makes it particularly easy to incorporate outputs into customer deliverables.

Prediction results at a glance, built-in task time libraries and images, a familiar spreadsheet interface, the flexibility to add judgments and difficulty factors, and extensive modeling capabilities all help put ASENT’s Maintainability Toolkit into a class by itself.
