Dependability (Availability & Reliability)   


Higher Availability, Reliability and Maintainability (ARM) offers both increased operational capability and reduced support costs.  Poor ARM characteristics can result in reduced operational effectiveness of a system, a greater risk of accidents and higher cost of ownership as well as a considerable reduction in customer satisfaction.  Good ARM characteristics are inherent in a design and cannot be a last minute add-on. 

 

SAS has experience of applying key standards, such as Defence Standards 00-25, 00-40, 00-41, 00-42, 00-43, 00-44, Military Standards 1629, 470 and British Standard BS5760.  In addition to this an SAS Team member helped to develop Def Stan 00-42 Part 3 on the R&M Case and is a member of the IMechE Committee developing strategies, guidance and Policy on R&M.  We can support your organisation in areas such as:    

  • Formulation of a cost effective Dependability Strategy and Programme    

  • Production and use of appropriate R&M Requirements based on stakeholder needs and trade-offs    

  • R&M Modelling and Prediction   

  • R&M trade off studies  

  • Failure Mode Effects and Criticality Analysis (FMECA) and Fault Tree Analysis 

  • Reliability-Centred Maintenance

  • Reliability Testing and Demonstration Trials

  • Defect / Data Reporting and Corrective Action Systems (DRACAS)

  • Production of System R&M Assurance documentation (e.g. R&M Case Report, Software Reliability Case)
