Natural Gas Pipeline Operation Schemes Comprehensive Evaluation Based on Multi-Hierarchy Grey Relational Analysis

並列摘要


In the condition of satisfying process requirement, determining the optimum operation schemes of natural gas pipeline network is essential to improve the overall efficiency of network operation. According to the operation parameters of natural gas network, the multi-hierarchy comprehensive evaluation index system is illustrated. This paper presents a multi-hierarchy grey relational analysis method which is suitable for evaluating the multi-hierarchy index system with combining the AHP and grey relational analysis. The comprehensive evaluating mathematic model for natural gas network operation schemes is built based on the method. Ultimately, the practical application shows that multi hierarchy grey relational analysis is effective to evaluate the nature gas pipeline network operation schemes.
