Flood control decisions are often involved with quantitative and qualitative criteria. In this paper, a fuzzy model is presented for flood control operations. Based on dual comparison, two models computing relative membership grades with qualitative and quantitative criteria are established, respectively. Subjective preference and iterative weights integrated method is proposed for weight-assessment...
A new approach of structural safety assessment for an existing rigid-frame arch bridge, constructed from multivariate and multi-layer analytic model. The assessment model of structural safety of existing rigid-frame arch bridges on the basis of technical condition, static loading test, dynamic loading test and load-carrying capacity, and the index system is proposed according to multivariate. In this...
To vehicle development problem, setting development targets is mainly based on the benchmark test data of competitors. Usually, the target setting is subjective and ambiguous. To reform the method, fuzzy decision-making matrices were established based on Analytic Hierarchy Process (AHP), hence, the comfort targets were set quantitatively. Then, the improved radar chart was used to make comprehensive...
