Variable Fuzzy Sets Model and Application on Water Shortage Risk Assessment
In the particular time and space environmental conditions, the water system occurred in the case of non expectation and the probability of occurrence and the resulting economic and non-economic loss is water system risk. An assessment method for water shortage risk based on variable fuzzy sets is presented in paper. Risk rate, weakness, possibility of recovery, period for reoccurrence and risk level are defined as the indexes for regional water shortage risk assessment. The suggested model is used to evaluate water shortage risk of Zhanghe irrigation region in Hubei Province in 2010 and 2020. The assessment results are in line with the situation about the level of water exploitation and utilization. The model expresses peoples knowledge and experience with fuzzy concepts and it is more operative to evaluate water shortage risk.
