Victoria Volodina, Nikki Sonenberg, Peter Challenor, Jim Q. Smith

摘要:

高斯过程(GP)仿真器被广泛用于在输入空间上近似复杂的计算机模型行为。受计算机模型耦合问题的影响,近年来在连通GP仿真器网络分析理论方面取得了一些进展。在本文中,我们结合这些最新的方法与经典的状态空间模型来构建贝叶斯决策支持系统。这种方法给出了一个连贯的概率模型,产生的预测与测量的不确定性方面的两个第一时刻,使不确定性的传播,从个人的决策组件。这种方法是用来产生一个决策支持工具,英国郡议会考虑低碳技术改造其基础设施,以达到净零碳目标。特别是,我们演示了如何耦合来自能源模型,供热需求模型,天然气和电力价格时间序列的信息,以定量评估各种政策选择和能源市场变化对运营成本的影响。

英文摘要:

Gaussian Process (GP) emulators are widely used to approximate complex computer model behaviour across the input space. Motivated by the problem of coupling computer models, recently progress has been made in the theory of the analysis of networks of connected GP emulators. In this paper, we combine these recent methodological advances with classical state-space models to construct a Bayesian decision support system. This approach gives a coherent probability model that produces predictions with the measure of uncertainty in terms of two first moments and enables the propagation of uncertainty from individual decision components. This methodology is used to produce a decision support tool for a UK county council considering low carbon technologies to transform its infrastructure to reach a net-zero carbon target. In particular, we demonstrate how to couple information from an energy model, a heating demand model, and gas and electricity price time-series to quantitatively assess the impact on operational costs of various policy choices and changes in the energy market.
