“…To face the factors of uncertain and imprecise information in real life situation, many theories have been developed, e.g. fuzzy sets [ 17 , 23 ], approximation theory [ 24 – 26 ] etc. Intuitionistic fuzzy sets (IFS) was introduced by [ 27 ] to assign non membership grades and it was studied by [ 28 , 29 ].…”

Objective This article introduces a novel approach called Digital Weighted Multi Criteria Decision Making (DWMCDM) that employs interval valued fuzzy sets to select the best contractor for building projects. The contractor is chosen based on the pre-qualification and bid evaluation phases. In the first phase, the distance between the actual and required skills of the significant criteria is determined, and it is then converted into digital weighted distances to identify the maximum number of criteria related to the specific project of each contractor. The second step ranks the best contractor based on the bid price and digital weighted distances. Results The suggested technique integrates the pre-qualification and bid review phases to address project award delays and other restrictions. Finally, a real-world application is addressed to demonstrate the applicability of the proposed approach to any type of interval valued fuzzy inputs.
