Evaluation on connectivity of urban waterfront redevelopment under hesitant fuzzy linguistic environment

“Connectivity” is the core planning strategy that is used to examine the features of functional and structural connections in urban waterfront redevelopment projects. According to SIA point of view, an index system of assessing urban waterfront redevelopment connectivity including 8 evaluation indexes is proposed from the hierarchy of ecological, social functional and contextual connections. In order to evaluate the connectivity of urban waterfront redevelopment, this paper proposes an interactive procedure for multi-attribute decision making under hesitant fuzzy linguistic environment, which allows the experts use several linguistic values to assess the connectivity index. A case study of typical redevelopment projects of Huangpu River Waterfront in Shanghai is analyzed to figure out the difference between landscape-restoration oriented projects and urban-exploitation projects. Theoretical analysis and computational results showed that the assessment index system is effective for measuring the social impacts generated by redeveloped projects.
