Ehsanifar, M and Hemesy, M (2021) A new hybrid multi-criteria decision-making model to prioritize risks in the construction process under fuzzy environment (case study: The Valiasr Street Underpass Project). International Journal of Construction Management, 21(5), pp. 508-523. ISSN 1562-3599
Abstract
Nowadays, the complexity of the construction projects naturally filled with uncertainties and risks is highly popular. Risk has negative influence such as deferment, injuries and fatalities. Therefore, to avert these disadvantages, the purpose of this article is to identify and prioritize risks. Hence, to reach this aim, in this study, a Multi-Criteria Decision-Making (MCDM) model combination of Shannon’s Entropy, Decision-Making Trial and Evaluation Laboratory (DEMATEL) and the COmplex PRroportional ASsessment of alternatives with Gray relations (COPRAS-G) methods is used. Since in most real environments, criteria are uncertain or fuzzy, fuzzy logic is applied to tackle this uncertainty. Note that all fuzzy data are represented by ordered fuzzy numbers (OFN). Finally, to demonstrate this approach the Valiasr Street underpass project is taken. The results indicate that the proposed model is capable of prioritizing risks properly that maximize returns and ensure sustainability.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
