Tavakolan, M and Etemadinia, H (2017) Fuzzy weighted interpretive structural modeling: Improved method for identification of risk interactions in construction projects. Journal of Construction Engineering and Management, 143(11): 04017084, ISSN 0733-9364
Abstract
The construction industry has a major role in the economic development of any country. Because of the nature of the construction industry and its unique characteristics, and the overtime work and overbudget funds spent on these projects, there are many risks which may occur during a project's lifecycle. Should a specific risk happen, the probability and impact of the other risks will be affected, which often affects the project's objectives. Therefore it is necessary to consider risk interaction in order to improve the management of project risks. This paper proposes the fuzzy weighted interpretive structural modeling (FWISM). A two-round Delphi method is applied by asking 10 experts to specify the importance of each risk interaction with a fuzzy number due to the uncertain nature of the risks. This paper presents a network of risk interactions in construction projects which then provide the necessary means for exploring the influence of and dependence among the risk factors. In order to identify the key factors that drive the system, MICMAC analysis is applied. The results show that contractual anomalies most influence the other risks of a given project, whereas certain risks such as construction delay or interruptions are more susceptible to these influences than are other risks.

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
