Structural Reliability, Optimization and Cost Analysis
With increasing optimization complexity, the computational resources required for the solution, especially if a multiobjective optimization problem is faced, typically increase with dimensionality of the problem at a rate that is more than linear. Therefore, massive computer resources are required for the design of realistic structures carrying a large number of load cases and having many components with several parameters describing the detailed geometry.
- Multi-Level Optimization
- Reliability Based Optimization (RBO)
- Reliability and Multi-fidelity Analysis
The application of health monitoring or condition monitoring systems serves to increase the overall reliability of a system through damage detection with 90/95 % reliability and predicting the remaining useful life (RUL) of critical components with confidence bounds.
The correct implementation of SHM can have positive impact on the live-cycle-cost of a structure and therefore presents a positive cost/benefit ratio. To do so, the factors which contribute positive or negative cost benefits must be identified and implemented through appropriate cost Analysis.
