Check dam system planning optimization based on mutation model
摘要
Abstract
The check dam system planning is a typical multi-criteria decision problem of complex system since the factors such as water and sediment control capacity,intercepting sediment capacity,silting land capacity and investment return and so on should be taken into account.The multi-criteria decision making of complex system usually has fuzziness and uncertainty.By making use of the advantage of catastrophe theory in dealing with the fuzzy and gray problems,an indicator system for evaluating check dam system planning was put forward,and a mathematical model was established to optimize the planning based on the mutation classification evaluation method,and then a detailed procedure was described to apply the model.The method has been applied to optimize the planning of check dam system in Liujian River,basin of Yanshi City.Firstly,all the indexes of bottom level were made dimensionless and normalized,and then the importance of each indicator was quantified by aggregation mechanism of the normalized formula; Finally,the optimum planning could be obtained by comparing total value of mutation subjection function of each planning.The total values of mutation subjection function of planning Ⅰ,Ⅱ and Ⅲ are 0.9592,0.9181 and 0.9484 respectively,thus planning Ⅰ is optimal.This result is consistent with that derived from the traditional method,suggesting the mutation model is reasonable and feasible for check dam system planning optimization.关键词
