PLANT LEVEL ENERGY SUPPLY ANALYSIS AND OPTIMIZATION IN ENERGY, ECONOMY AND ENVIRONMENT

摘要

Increasing attention has recently been drawn to the energy consumption of the manufacturing process. Facing the challenges from reducing emission, rising raw material prices and energy costs, manufacturers are trying to balance the energy usage strategy among the total energy consumption, economy and environment, which can be self-conflicting at times. This paper focuses on the objective optimizations of a plant level energy supply system, and describes how a multi-objective optimization strategy can be effectively formulated for making the best use of energy delivered to the manufacturing process. An example from an automotive assembly manufacturer is described.
