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 ...
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 ...
An Optimization Framework for Decision Making in Large, Collaborative Energy Supply Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As demand for electricity in the U.S. continues to increase, it is necessary to explore the means through which the modern power supply system can accommodate both increasing affluence (which is accompanied by increased ...
