RISConservative Surrogate Model Using Weighted Kriging Variance for Sampling Based RBDO
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In samplingbased reliabilitybased design optimization (RBDO) of largescale engineering applications, the Monte Carlo simulation (MCS) is often used for the probability of failure calculation and probabilistic sensitivity ...
Value of Information in MultiAttribute Decisions With Applications in Ground Vehicle Autonomy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents some results in the value of information calculations for multiattribute decisionmaking under uncertainty. Almost all engineering activities are undertaken in the face of uncertainty and a decision that ...
Efficient Reliability-Based Mission Planning of Off-Road Autonomous Ground Vehicles Using an Outcrossing Approach
Publisher: The American Society of Mechanical Engineers (ASME)

Optimizing the Reliability and Performance of Remote Vehicle to Grid Systems Using a Minimal Set of Metrics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vehicles connected to electric systems are considered “plugin†vehicles. They can be an integral part of a microgrid. Ground vehicles have become more electrified over time, providing electrical power for the propulsion ...
Reliability-Based Design Optimization Using Confidence-Based Model Validation for Insufficient Experimental Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The conventional reliability-based design optimization (RBDO) methods assume that a simulation model is able to represent the real physics accurately. However, this assumption may not always hold as the simulation model ...
Maximizing Design Confidence in Sequential Simulation Based Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational simulation models support a rapid design process. Given model approximation and operating conditions uncertainty, designers must have confidence that the designs obtained using simulations will perform as ...
