Development of an urban water and land use management systems planning model in a mixed stochastic and fuzzy environment
In this study, an urban water resources and land use management model (UWR-LUMM) was developed for supporting the planning of water and land use system under uncertainty at an urban scale. This modeling method is based on an interval fuzzy stochastic programming (IFSP), which is the integration of fuzzy linear programming (FLP), interval linear programming (ILP) and chance-constraint programming (CCP). Such an approach can effectively tackle the multiply uncertainties expressed as interval numbers, probabilistic distributions, and fuzzy sets existing in water resources systems, fully considering the inexact features related with economic factors and random characteristics of stream conditions. More importantly, the water manager‘s preferred system satisfaction degrees can be directly reflected in the modeling process, and thus greatly reduce the subjectivity of decision making, enhancing the stability and robustness of obtained solutions. The developed method was then applied to a case of urban water and land use system planning and five scenarios related to green cover ratio were designed. The generated results can provide decision makers with detailed water and land use management schemes under various system conditions and scenarios, allowing more in-depth analysis of the trade-offs between economy and environment, as well as those between system optimality and reliability.
