2.3 Entropy Weight Method for the Assessment
of Environmental Sanitation Sustainability Conditions
The entropic weight method for weighting indicators and subsystems is explained
by Toumi et al. (2017). The methodological steps for calculating the Environmental Sanitation Sustainability Conditions Index (CSS) are presented in Fig. 2. This
overall indicator allows for the definition of a 5-grade evaluation criteria of the overall sustainable development level referring to the evaluation criteria of sustainable
development level resources. This coefficient reflects the development situation and
trend for the GD1 and GD8 water management units at the River Grande Basin.
These grades are displayed in Table 2.
