Abstract
Today, the focus on risks and uncertain events is one of the essential goals of any organization. If hazards are not taken into consideration at the planning stage it could be dangerous during project life cycle. Therefore, risk assessment is so important which has been extensively investigated by many researchers in recent years. This research suggested a method based on a combination of two WSM models (weighted sum model) and WPM (weighted product model), known as the weighted aggregated sum product assessment (WASPAS) method which was employed to assess negative effects of risks on project. This method has capability and more accuracy compared to independent methods in alternatives ranking. The WASPAS method is one of the new multi-index decision-making techniques which has been adopted and employed in many areas. In this research, we identified and evaluated the risks of a road construction project in Iran which the results showed inaccessibility/inappropriate of barrow pits, loss of key manpower during project life cycle, employing inexperienced subcontractors are of the most important risks among identified risks. Also this paper suggested the WASPAS method as a suitable method with more accuracy among MCDM techniques for evaluating of risks in a real situation.

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
