Dynamic multi-attribute decision making model with grey number evaluations

In this study, both the Minkowski distance function and the grey number distance function are integrated into the TOPSIS to develop a dynamic multi-attribute decision making model for effectively handling the uncertain information. An illustration example of subcontractors’ safety performance evaluation is adopted to demonstrate the practicability of the proposed model. Results show that the proposed model can effectively deal with the uncertain information risk and does not cause more computational burden.
