Multi-Objective Bayesian Optimization for Networked Black-Box Systems: A Path to Greener Profits and Smarter Designs

  • 基于函数网络建模系统,支持循环依赖与反馈回路
  • 在真实案例中实现多目标高效优化,提升设计可持续性
  • 适合复杂工程系统设计者,尤其关注绿色与高利润平衡

现代工业系统设计需权衡利润、韧性与可持续性等多重目标,同时考虑技术、经济与环境因素的复杂交互。传统多目标优化方法在系统从白箱到黑箱的不同表示下选择困难,而现有灰箱方法常施加刚性结构假设,迫使模型服从求解器结构,而非灵活适配系统本体。本文提出一种统一的灰箱多目标优化框架——MOBONS,基于网络表示将系统建模为共享输入输出的函数节点图,可高效处理含循环依赖的通用函数网络,支持反馈回路、回流流程与多尺度仿真。该算法结合约束处理、并行评估能力,保持贝叶斯优化的样本效率,同时利用网络结构提升可扩展性。通过两个案例验证,包括可持续工艺设计,MOBONS展现出在一般图结构下高效实现多目标优化的潜力,显著提升工程系统在利润、韧性与可持续性方面的综合表现。

原文摘要 · Abstract (English)

Designing modern industrial systems requires balancing several competing objectives, such as profitability, resilience, and sustainability, while accounting for complex interactions between technological, economic, and environmental factors. Multi-objective optimization (MOO) methods are commonly used to navigate these tradeoffs, but selecting the appropriate algorithm to tackle these problems is often unclear, particularly when system representations vary from fully equation-based (white-box) to entirely data-driven (black-box) models. While grey-box MOO methods attempt to bridge this gap, they typically impose rigid assumptions on system structure, requiring models to conform to the underlying structural assumptions of the solver rather than the solver adapting to the natural representation of the system of interest. In this chapter, we introduce a unifying approach to grey-box MOO by leveraging network representations, which provide a general and flexible framework for modeling interconnected systems as a series of function nodes that share various inputs and outputs. Specifically, we propose MOBONS, a novel Bayesian optimization-inspired algorithm that can efficiently optimize general function networks, including those with cyclic dependencies, enabling the modeling of feedback loops, recycle streams, and multi-scale simulations - features that existing methods fail to capture. Furthermore, MOBONS incorporates constraints, supports parallel evaluations, and preserves the sample efficiency of Bayesian optimization while leveraging network structure for improved scalability. We demonstrate the effectiveness of MOBONS through two case studies, including one related to sustainable process design. By enabling efficient MOO under general graph representations, MOBONS has the potential to significantly enhance the design of more profitable, resilient, and sustainable engineering systems.
