Designing hierarchical model for risk mitigation in project supply chain based on meta-synthesis (Case Study: Fars Gas Company)

According to gas development in most provinces in recent years and the expansion of gas transfer pipeline in parallel، paying attention to project supply chains and related risks is necessary more than past. Due to specific structure of project supply chain based on government regulations، this article is aimed at presenting a model to mitigate risks on projects supply chain in State gas companies. In order to do that، we have used a mixed methodology approach in this research. According to Meta-synthesis and content validity، risk mitigation strategies are identified and classified. Moreover، by using Interpretive Structural Modeling (ISM)، mutual relationships and the degree of influences of each strategy on each other are recognized. Results show that managers must attend to those strategies that have high driving power and low dependency than low driving power and high dependency. As a result، by concentrate on key variable، supply chain risks can be mitigated effectively.
