摘要
评价和筛选最优的储气库建库方案能够为储气库安全高效运行提供保证。为此,建立了评价地下储气库方案的指标体系结构,并对指标参数进行归一化处理;应用突变理论和模糊数学相结合的方法产生突变模糊隶属函数,应用该隶属函数对地下储气库方案进行综合评价和筛选。该模型避免了模糊评价法、灰色物元法及层次分析等方法需要人为给定指标权重的弱点,减少主观性又不失科学性,对地下储气库方案的优选具有指导意义。
A new assessment method combined catastrophe theory and fuzzy mathematics is established and applied for the first time to evaluate and select the optimum project of the underground gas storage, in which subordinate functions of assessment indexes are derived with the combination of catastrophe theory and fuzzy mathematics. Based on these subordinate functions, comprehensive values of all candidate underground gas storage projects are calculated, on which we base to select the best project. From example testing, it shows that result evaluated by the method is in accordance with other evaluation method's very well. The method can ensure the veracity and creditability of the evaluated result and avoid the randomicity and troubling of hierarchy process, factor analysis, fuzzy comprehensive appraisal and other assessment methods.
