Evaluating the impact of risk management and green supply chain on the success of projects using structural equation modeling (case study: Iran's defense industry)

Defense industries are considered as one of the most important pillars of a nation's national power and one of the most strategic and important sectors due to their role in creating a deterrent capability against foreign threats, and therefore they are effective in creating and promoting national security from which the whole society benefits. On the other hand, the performance of the defense sector is tied to the supply chain performance and project risk management to a large extent. Defense industries as set of project-based organization with a high-tech, always need to use new tools and methods in these projects and projects success in this sector and maintain the continuity of network operations, is highly dependent on having strong and stable supply chains and the ability to project risk management. Therefore, identifying and evaluating risks and hazards can provide better and more accurate decision-making conditions for project management and achieve the goals and success of defense projects. So, research about it is one of the important and basic issues in this field. In this study, in order to evaluate the improvement of project management based on risk management and green supply chain in products related to defense industries, data on project risk management variables, green supply chain management, project management performance and project success were collected using a questionnaire. Based on the results, according to the model hypotheses and modeling of structural equations, the partial least squares method was implemented in SmartPLS software. The analysis of the results indicates a suitable model and good effect of variables. According to the results obtained in the model fit, all variables in all domains gained a good amount of validity and reliability in the model. Also, in the overall effects of the model, it was shown that all the relationships and effects of the variables of project risk management and green supply chain management on project management performance and project success are significant. Therefore, it can be concluded that project risk management and green supply chain management are two important and fundamental factors in project management performance and project success in our country's defense industry.
