Decision Support for Enhancement of Manufacturing Sustainability: A Hierarchical Control Approach
2018
Moradi-Aliabadi, Majid | Huang, Y. (Yinlun)
From the sustainability science point of view, improvement of manufacturing sustainability involves a series of system (performance) state transitions in a sustainable development (SD) space. The transitions occur based on the system information obtained through stage-wised sustainability assessment and the actions on the system taken based on the derived stage-wised decisions. From the standpoint of control engineering, this is a multiobjective system control problem. In this paper, we introduce a general decision-support framework for deriving strategies to achieve short-to-long-term sustainability goals. In this framework, a two-layered hierarchical control scheme is introduced to implement strategic and tactical control for dynamic sustainability control. A comprehensive case study on biodiesel manufacturing is illustrated to demonstrate methodological efficacy.
