paper refines extends fundamental ways existing model numerical assessment sustainability called sustainability assessment fuzzy evaluation safe safe basic form uses fuzzy logic combine large suite basic indicators computes numerical values sustainability number composite indicators air land economy health etc higher hierarchy computes sustainability ecological human component finally computes overall sustainability country region stateoftheart fuzzy analysis advanced prompted modify safe accordingly refined model uses socalled takagisugenokang inference scheme tsk together technical requirements guarantees monotonicity ie improvement basic indicator leads improvement sustainability another refinement concerns data inputs include effects past environmental pressures development policies present state sustainability use exponential smoothing take account past exponentially decaying weights finally model applied countries world data could obtained corresponding sustainabilities computed also sensitivity analysis important indicators affect sustainability identified
