Projects and Publications

Since our founding in 1978 SoHaR has been involved in hundreds of commercial and government contracts that have led to numerous successful R&D activities and an abundance of publications.

SoHaR's ability to support programs and projects in the wide areas of sustainability: reliability, maintainability, availability, safety and logistics, has lead us to successes in many industries and a variety of products and services. Notable among these are projects in the domains of

  • air traffic control,
  • avionics,
  • flight control,
  • ground based support and control,
  • communication systems,
  • C3I and battle management,
  • safe MEMS fuse devices,
  • nuclear power,
  • space systems,
  • fault tolerant components and methods.

These successes are based on a wide portfolio of techniques and methods that enable us to pinpoint the best solutions and processes to our customer's needs. Our work covers the gamut of program sustainability tasks:

  • Reliability, maintainability and availability prediction: from the most common components through one of a kind components and systems with complex usage and environment condition profiles.
  • Dependability modeling: Reliability Block Diagrams through Markov & Petri Net analysis and full scale simulations.
  • Safety Analysis: Hardware FMEA, Software FMEA, Fault Tree Analysis, Hazard analysis, Sneak Circuit Analysis, interdependent networks and vulnerabilities.
  • Logistics: spares optimization/analysis, Failure analysis, FRACAS (Failure Reporting Analysis and Corrective Action Systems).
  • LifeCycle Cost: analysis, optimization, risk assessment.
