Evaluating large, high-technology project portfolios using a novel interval-valued Pythagorean fuzzy set framework: An automated crane project case study

作者：

Highlights：

• A novel method for ranking IVPFSs is presented and implemented in the evaluation algorithm;

• A new IVPFS based method of linear assignment and an IVPFS knowledge index are introduced;

• The relative superiority/inferiority of experts is computed;

• A new multi-objective model is presented to address portfolio value optimization;

• A case of high-tech automated crane projects in port operations has been used.
