Energy is considered as one of the important factors for manufacturers to achieve the sustainability objective. To improve energy efficiency in manufacturing, optimization techniques are essential to provide decision support. However, formulating and solving energy optimization in manufacturing is still time-consuming and difficult due to its complexity with a broad scope. In addition, it is a challenging task since it requires substantial development efforts and modeling expertise. To address this drawback, Sustainable Process Analytics Formalism (SPAF) is proposed to facilitate the modeling and optimization. In this paper, SPAF will be applied to a case study of energy optimization for a book binding production system for its feasibility validation. The knowledge of process flow, data, and metrics of the case study is represented using SPAF, and a preliminary analysis of optimization results was performed.
