World Leading Reliability Prediction Software

Reliability Prediction Software

ITEM ToolKit Software

Item Software’s reliability software ITEM ToolKit is a suite of comprehensive prediction and analytical modules in one integrated environment. ToolKit is an integrated environment benefiting from object-oriented architecture that delivers Accuracy, Flexibility and Ease of Use. It offers you convenient features that provide a consistent format for all your analyses. This enables learning carry-over from one module to another.

Hierarchy Diagrams

Users can interactively construct hierarchy diagrams that represent the structure of a system at various hierarchical levels. As new components are added to the system, each module automatically calculates and updates all dependent and overall failure rates.

MTBF and Failure Rate Calculations

Mean Time Between Failure Calculation (MTBF) and Failure rates are automatically computed and displayed for all levels of systems and projects. Advanced hybrid linking and modeling and user defined custom libraries are also standard features of our reliability software tools.

Parts Count and Parts Stress Analysis

When adding components to your system, ITEM ToolKit automatically employs the applicable default values (Parts Count). The Parts Count generally requires less information such as part quantities, quality levels and the application environment. It is most applicable early in the design phase and proposal formulation.

Redundancy & Repairable Calculations

Each reliability software module of ITEM ToolKit includes redundancy and repairable options for calculations of availability and failure rates at block and system levels.

MIL-HDBK-217 Module

The MIL-HDBK-217 Module of ITEM ToolKit reliability software is a powerful reliability prediction program based on the internationally recognized method of calculating electronic equipment reliability defined in MIL- HDBK-217 (published by the US Department of Defense). This standard uses a series of models for various categories of electronic, electrical and electro-mechanical components to predict failure rates that are affected by environmental conditions, quality levels, stress conditions and various other parameters. These models are fully detailed within MIL-HDBK-217.

Telcordia Module

The Telcordia Software Module of ITEM ToolKit calculates the reliability prediction of electronic equipment based on the Telcordia (Bellcore) TR-332 and SR-332 standards. These standards use a series of models for various categories of electronic, electrical and electro-mechanical components to predict steady-state failure rates which environmental conditions, quality levels, electrical stress conditions and various other parameters affect. It provides predictions at the component level, system level or project level for COTS (Commercial Off-The-Shelf Parts).

IEC-62380 Module

The ITEM ToolKit reliability software’s IEC-62380 module supports reliability prediction methods based on the latest European Reliability Prediction Standard. Originally, a French Standard published by the Union Technique de L’Electricite (UTE, July 2000 – RDF). The standard has evolved and become the European Standard for Reliability Prediction (IEC-62380). Its unique approach and methodology has gained worldwide recognition. IEC-62380 is a significant step forward in reliability prediction when compared to older reliability standards.

IEC-61709 Module

The reliability software module IEC-61709 operates based on the European prediction standard IEC-61709 for reliability prediction. This ITEM ToolKit module adheres to section 19 of the European prediction standard IEC-62380 (RDF 2000/UTE C 80-810) for PCBs and section 20 for hybrid circuits. It is primarily based on the Siemens Prediction Standard SN-29500.

NSWC Module

The NSWC module of ITEM ToolKit reliability software uses a series of models for various categories of mechanical components to predict failure rates based on temperature, stresses, flow rates and various other parameters. Standard procedures for predicting the reliability of mechanical components, sub-systems and systems are defined in the Naval Surface Warfare Center Handbook of Reliability Prediction Procedures for Mechanical Equipment (NSWC 06/LE1).

China 299B Module

The China 299B Module of ITEM ToolKit reliability software is a powerful reliability prediction program based on the internationally recognized method of calculating electronic equipment reliability provided in the Chinese Military Standard. This standard uses a series of models for various categories of electronic, electrical and electro-mechanical components to predict failure rates that are affected by environmental conditions, quality levels, stress conditions and various other parameters.
