Fuzzy Variable Assessment of Urban Flood Control System Safety in Jinan

Abstract:

Article Preview

Urban flood control system is a collection of various preventive measures taken to resist and mitigate flood. Assessment of urban flood control system safety is one of the important measures to coordinate the urban social planning and the urban flood control facilities.The assessment can also promote the sustainable development of city.In allusion to urban flood control system safety is a fuzzy concept with vague denotation, a fuzzy variable assessment model of urban flood control system safety is constructed in this paper based on theories of variable fuzzy sets and relative different functions.The method can determine relative membership degrees and functions of various indexes associated with the urban flood control system safety scientifically and reasonably; through changing the model,the stability of grade eigenvalues is tested; the mean of grade eigenvalues is calculated to improve the reliability of assessment results. The synthetical assessment of flood control system safety can be implemented with the method adopted in this paper.By 4 safety grades, 9 key indexes were screened in the urban flood control system of Jinan to implement the safety assessment in this paper. The case study of Jinan shows that the proposed method is of practical use.
