Reliability
RAM Commander provides everything necessary for primary reliability prediction based on one of the prediction models for electronic equipment, mechanical and electro-mechanical equipment. Graphical presentation of the projects Product Tree allows visibility and easy data manipulation
Pareto Report. Pareto analysis identifies components or component families that contribute most significantly to system or assembly failure rate - about 80% of total failure rate

RBD with Monte-Carlo simulation
RBD module allows performing the functional Reliability and Availability analysis of systems with variety of reliability distributions, and types of redundancy and repair factors. While the basic RAM Commander module provides the reliability calculations and predictions for non-redundant systems, RBD utilizes data defined in the basic module, and performs either analytica l calculation or Monte Carlo simulation depending on the type of a reliability configuration of the system.

Maintainability
Maintainability Prediction in RAM Commander is based on the MIL-HDBK-472, Procedure V, Method A. Maintainability module is used to predict maintainability of systems and equipment of any type, including avionics, ground and shipboard electronics, mechanical equipment, etc., at all levels of maintenance.

Spare Parts Optimization
RAM Commander Spare Parts Analysis and Optimization is based on two cost optimization criteria: Total No Shortage Probability & Availability. The module performs Cost-Availability optimization of repairable and discardable parts for all levels of repair

Derating
The Derating module is used to analyze the overstress of components under current temperature conditions. The module provides a tool to define Derating curves and identify overstressed components, i.e., those working under stress exceeding the specified rating value.

FMECA
Failure Mode, Effects and Criticality Analysis (FMECA) is a natural continuation, and in many cases inseparable part of the Reliability Analysis. FMECA module uses a product tree previously created by the user for the reliability analysis purposes.

|
Testability
Testability Analysis sub-module of the FMECA module is intended for in-depth Testability analysis. The main characteristics of Testability - BIT/Detection Coverage and Fault Isolation Resolution - can be calculated for each maintenance level (Organizational, Intermediate, Depot) and for specific detection methods (BIT, BITE, external test equipment, etc.).

Design & Process FMEA
This module performs Process/Design potential Failure Mode and Effects Analysis. The uniqueness of the RAM Commander approach to process/design FMEA is reflected in the graphical presentation of the process flow:

Fault Tree Analysis (FTA)
RAM Commander's FTA module is the one of the unique features of the RAM Commander. It is simplified FT Analyzer, fully integrated with RAM Commander product tree and FMECA. It implements and summarizes the first-hand experience gained by the A.L.D. FTA experts in hundreds of projects using RAM Commander and other FTA software
