Abstract: There are many factors involved in the design projects of underground gas storages.Therefore,it is necessary to establish a right decision model to comprehensively evaluate the design projects.The procedures of the improved analytic hierarchy process and the principles of fuzzy comprehensive evaluation were briefly introduced.The decision model combined by the improved analytic hierarchy process and fuzzy comprehensive evaluation was applied to the optimization of projects for some underground gas storage in Beijing.Eight main factors involving the construction of the underground gas storage were considered during the whole optimization process.Four assessment grades for six projects were established,including extraordinary,good,ordinary and bad.Then the weights of all factors were determined,and the fuzzy comprehensive evaluation of each project was conducted.The project selected by this decision model matches the applied project on-site,which shows the applicability of this model.

Key words: improved analytic hierarchy process, fuzzy comprehensive evaluation, underground gas storage, design project, decision model
