Probabilistics Design Optimization

STI Technologies is a national leader in providing probabilistic design capabilities. STI's probabilistics experience includes:
  • Probabilistic/Risk-Based Component Design
  • Probabilistic FEA for Design Risk and Sensitivity Evaluation
  • Probabilistic/Fuzzy logic Health Management System
  • Probabilistic/Fuzzy logic Fault Diagnosis Using Advanced Stochastic Classifiers
  • Probabilistic Condition Assessment and Remaining Life Prediction Under Random Operational Environments
  • Risk-based Life Assessment/Extension, including Optimum Maintenance Strategy (Minimum Cost)
This expertise is emphasized by a 20 year, successful working relationship with the U.S. Air Force. STI has developed probabilistics-related software, performed extensive consulting and organized and conducted specialized workshops for the power generation, nuclear and aerospace industries.
