RISUnderstanding Resilience Optimization Architectures: Alignment and Coupling in Multilevel Decomposition Strategies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Including resilience in an overall systems optimization process is challenging because the space of hazard-mitigating features is complex, involving both inherent and active prevention and recovery measures. Many resilience ...
Bilevel Flexible-Robust Optimization for Energy Allocation Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A common issue in energy allocation problems is managing the tradeoff between selling surplus energy to maximize short-term revenue, versus holding surplus energy to hedge against future shortfalls. For energy allocation ...
An Approach to Bayesian Optimization for Design Feasibility Check on Discontinuous Black-Box Functions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents a novel approach to applying Bayesian Optimization (BO) in predicting an unknown constraint boundary, also representing the discontinuity of an unknown function, for a feasibility check on the design ...
Constraining the Feasible Design Space in Bayesian Optimization With User Feedback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper develops a method to integrate user knowledge into the optimization process by simultaneously modelling feasible design space and optimizing an objective function. In engineering, feasible design space is a ...
A Nested Weighted Tchebycheff Multi-Objective Bayesian Optimization Approach for Flexibility of Unknown Utopia Estimation in Expensive Black-Box Design Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We propose a nested weighted Tchebycheff Multi-objective Bayesian optimization (WTB MOBO) framework where we built a regression model selection procedure from the ensemble of models, toward better estimation of the uncertain ...
Quantifying the Resilience-Informed Scenario Cost Sum: A Value-Driven Design Approach for Functional Hazard Assessment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Complex engineered systems can carry risk of high failure consequences, and as a result, resilience—the ability to avoid or quickly recover from faults—is desirable. Ideally, resilience should be designed-in as early in ...
Human-in-the-Loop Bayesian Optimization for Artificial Intelligence-Guided Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. To address large-scale problems such as ocean cleanup and reforestation, engineers need to develop novel solutions that can effectively cover a wide area and adapt to a variety of situations. To design a complex ...
Design of Complex Engineered Systems Using Multi-Agent Coordination
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In complex engineering systems, complexity may arise by design, or as a by-product of the system's operation. In either case, the cause of complexity is the same: the unpredictable manner in which interactions among ...
Robust Topology Design of Complex Infrastructure Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Optimizing the topology of complex infrastructure systems can minimize the impact of cascading failures due to an initiating failure event. This paper presents a model-based design approach for the concept-stage robust ...
Understanding the Impact of Decision Making on Robustness During Complex System Design: More Resilient Power Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Robust design strategies continue to be relevant during concept-stage complex system design to minimize the impact of uncertainty in system performance due to uncontrollable external failure events. Historical system ...
