Uncertainties arising from extreme climate events and human activities pose a challenge to the efficient allocation of water resources. In this study. a type-2 fuzzy chance-constrained linear fractional programming (T2F-CCLFP) is developed to support the water resource management system under uncertainty by incorporating type-2 fuzzy sets. chance-constrained programming. https://parisnaturalfoodes.shop/product-category/promasil-natural-vanilla/
