Reliability Engineering
RELIABILITY ENGINEERING SERVICES
- Prediction of hardware reliability of electrical/avionic systems using MIL-HDBK-217F, Tecordia, etc.
- Establishing definite Reliability & Maintainability (R&M) goals, both qualitative and quantitative, based on an extensive literature survey and collection of performance data from past experience.
- Reliability apportionment and allocation of definite work packages to various design disciplines (such as mechanical, electrical, avionics, hydraulics, etc.) for estimating system reliability.
- Estimation or optimization of reliability of mechanical components such as gears, bearings, and shafts.
- Prediction of hardware reliability of electrical/avionic systems using MIL-HDBK-217F, Tecordia, etc.
- Establishment of a proper failure reporting, analysis, and corrective action system (FRACAS) to record the failures/snags encountered during the prototype development phase and in-service.
- Preparation and coordination of failure mode, effects, and criticality analysis (FMEA/FMECA) reports on various systems, both mechanical and electrical/electronic.
- Preparation of fault tree analysis (FTA) reports.
- Estimation of MTBF for components, equipment, and systems.
- Creation and maintenance of an extensive Database on developmental snags and their corrective actions as part of the management information system.
