Extension of weighted aggregated sum product assessment with interval-valued intuitionistic fuzzy numbers (WASPAS-IVIF)

- The weighted aggregated sum product assessment is used to improve the accuracy of weighted sum and weighted product models.
- An extended version of weighted aggregated sum product assessment (WASPAS method) is proposed for soft computing.
- In the proposed WASPAS-IVIF method, the uncertainty is expressed by interval valued intuitionistic fuzzy numbers.
- Numerical example demonstrates strengths of combining IVIFS in handling uncertainty with the enhanced accuracy of WASPAS.
