MTain Projects
MTain has experience in the various phases and elements of the reliability, maintainability, safety and logistics engineering programs, on different product types and technologies. This experience includes the development of proposals for various projects and the respective planning of personnel resources and work breakdown structure (WBS) elements and the identification of the support required from key suppliers and subcontractors. This extends to the actual implementation and execution of projects and the related tasks and activities. The activities had been tailored to meet the specific objectives and needs for each project. Other aspects had also been covered, from the R&M and logistics assessment of many other systems and equipment, development and Off-The-Shelf (or Non-Developmental Items (NDI)). These had been achieved in varying dynamic engineering environments and has included:

  • Development of reliability and maintainability (R&M) and logistics engineering program plans aligned with the program strategies.
  • Proposal developments, for the inclusion of reliability and maintainability and logistics engineering activities. Many proposals had resulted in an "upfront" engineering effort  to address fundamental R&M and logistics engineering concerns. R&M issues would include the assessment of a proposed system (or equipment) architecture, to determine if it would achieved the required reliability performance requirements. The logistics assessments have involved implementing preliminary maintenance concepts and an assessing the anticipated Life Cycle Cost (LCC) factors.
  • Assessment and acquisition process of various reliability, maintainability and logistics software tools and databases
  • Development of departmental reliability, maintainability, logistics engineering procedures used for accreditation to standards such as IS0 9001.

OBJECTIVE: To demonstrate through analysis the Built-In-Test effectiveness.
APPROACH: Implement an Failure Mode Effects and Criticality Analysis (as per MIL-STD-1629) and reliability prediction (as per MIL-HDBK-217). The FMECA was conducted down to a functional level for each circuit card assembly, and each functional failure mode was assessed to determine if the BIT would detect it. This the detection rate was weighted using the failure rate.
CONCLUSION: The effectiveness was proven to be better than the requirement, in providing an end-to-end GO-No GO BIT status.
