Mathematical risk assessment models for invasive alien plant species: Fuzzy symmetric and asymmetric linguistic scale approach
The main aim of this research is to develop mathematical models to assess the invasive potential of alien plant species. The parameters used to define this potential are expressed as linguistic variables, which are often imprecise and uncertain. To handle this, the fuzzy 2-tuple linguistic…
