Development and optimization of unrestricted LR-type intuitionistic fuzzy mathematical programming problems

作者:

Highlights:

• We have defined the score and accuracy indices of LR-type IFNs.

• We have derived some results based on these indices.

• The product of unrestricted LR-type IFNs using α, β & (α, β)-cuts have been defined.

• A new method for unrestricted LR-type fully IFPPs have been proposed.

• An illustrative example is given to support the proposed method.
