QUALIFLEX method for evaluating human factors in construction project management with Pythagorean 2-tuple linguistic information

The overall quality evaluation of operation personnel helps contain site safety accidents, in this study, we proposed a combination of the Pythagorean 2-tuple linguistic fuzzy set and qualitative flexible multiple criteria (QUALIFLEX) method to evaluate comprehensive quality of operation personnel in engineering projects, Pythagorean 2-tuple linguistic fuzzy numbers to express decision makers' evaluation on each scheme with original QUALIFLEX approach to decision making process. In the end, an example of the performance evaluation of operation personnel in the engineering project is provided to test the applicability and practicability of the method, comparison analysis for further elaboration.

Automated summary

The study proposes a method that combines Pythagorean 2-tuple linguistic fuzzy set and QUALIFLEX to evaluate the comprehensive quality of operation personnel in engineering projects, with an example provided to test its applicability and practicability.
