Energy Efficiency Evaluation and Optimization of Industrial Park Customers Based on PSR Model and Improved Grey-TOPSIS Method

Energy efficiency evaluation of industrial park customers is carried out to help develop optimization strategies and improve the energy level. The indexes are proposed based on pressure-state-response (PSR) model redundant selected by combining principal component analysis (PCA) correlation analysis. Thus dynamic index system constructed. weight calculated entropy method (EWM). An improved Grey-technique for order preference similarity ideal solution (TOPSIS) proposed, which replaces Euclidean distance weighted grey degree can accurately evaluate customers' maximize benefits while improving efficiency. validity models verified case study an park.
