Abstract：

In order to ensure execution effectiveness of tiered pricing system for residential gas consumption and provide a reference basis for those areas in which such system has not yet been executed, it is necessary to evaluate advantages and disadvantages of such system. Based on the research results in current domestic tiered pricing for residential electricity and water consumption, analyzed is implementation situation of tiered pricing in residential gas consumption and applied are methods of mathematical statistics and fuzzy mathematics to evaluate advantages and disadvantages of tiered pricing system for residential gas consumption. The analysis results show that normal distribution model may be used to determine whether the tiered pricing for residential gas consumption can ensure the smooth and steady gas consumption of 80% households. Based on considering many factors, applied is the fuzzy comprehensive evaluation method to conduct further investigation and study on the tiered pricing system. Finally, put forward are some suggestions for tiered pricing system making and further improvement in future execution period.
