Product Description

RAM Commander is a Reliability and Maintainability software for reliability professionals and design engineers. This powerful software program covers the entire scope of engineering tasks related to reliability of electronic, electro-mechanical, and mechanical systems. Modules cover: Reliability Prediction Reliability Block Diagram with Monte Carlo Simulation Maintainability Spare Parts Analysis & Optimisation Derating Guidelines and Reports FMECA Analysis Testability Analysis Process & design FMEA Fault Tree Analysis (FTA) Safety Module RAM Commander is modular software allowing a customer the flexibility of gradual addition of the modules to the package in accordance with the requirements of a project or the budget constraints Prediction Methods: MIL-HDBK-217 TR332 - Bellcore Issue 6 SR332 - Telcordia 2001 RDF 95 - French Telecom UTEC 80810 (CNET 2000) HRD - British Telecom GJB299 - Chinese Standard IRPH93 - Italtel ALCATEL RADC 85-91 NPRD-95 NSWC-98/LE1 Mechanics Siemens SN 29500-1 FIDES IEC 62380 Reliability Prediction 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. Performing reliability allocation, Pareto analysis, RAM sensitivity analysis producing temperature curves and mission profile are extremely easy with RAM Commander.RAM Commander produces all commonly required reliability reports and allows the user to define customized reports.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 Temperature Curve Report. Presents the failure rate or MTBF as a unction of temperature: regular, multi-environment & multi-items on one graph. Reliability Block Diagram (RBD) 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 analytical calculation or Monte Carlo simulation depending on the type of a reliability configuration of the system. The analytical technique is used mostly for exponential distributions. For each RBD, a graph of the reliability function R(t) can be drawn and MTBCF (Mean Time Between Critical Failures) can be calculated using numeric integration. Monte Carlo simulation with its' high speed, accuracy, and large number of steps allows to evaluate Reliability and Availability for arbitrary configurations when there is no analytical solution, i.e. complex configurations, including standby, partially loaded and active redundancy; full or restricted repair with non-exponential distribution of time-to-repair; analysis under non-steady, transient state; dependent RBD elements; analysis of periodical inspection policy. System Configuration feature of the RBD module is an ingenious answer to the requests of our customers who need to compare the reliability and availability of various system configurations created as the sub-sets of the project product tree. The creation of the unlimited number of system configurations, easy transformation of each configuration into an RBD, MTBCF calculation, synchronized with the product tree changes, and finally a clear and elegant graphical presentation - all this makes the System Configuration feature an invaluable addition to the RAM Commander performance. 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 analysis and 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. Spare Parts Analysis and Optimization module takes into account the variety of mission applications, e.g., when the primary restriction is weight or volume, such as for fly-away kits or when no repair or supply of spare parts is permitted (unsupported mission). Data entry for the module is minimized due to the usage of the data used in the RAM project. 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. Rating, or maximum rated stress, is the specified value of temperature, power, voltage or current that define the absolute maximum stress limits. Exceeding these values creates a high probability of part damage/failure. The maximum rating is specified in the part specifications or in standard for this type of part. It is a well known practice in many companies to define limit values of stress for various components as a function of temperature. These limits, "Derating curves", are part of the company policy of component usage. A report created by the Derating module includes all components in the selected part of the system, or only the overstressed ones. Derating reports with indication of overstressed parts. Libraries and Data Import RAM Commander enables the user to access and use various sources of reliability information: extensive RAM Commander or user-defined component libraries, field data or data imported with the help of Import Wizard.
