Evaluating impact of risk elements affecting sustainability of enterprises is now becoming one of the streams of research in supply chain risk management area. However, previous scientific studies dedicated to improve supply chain sustainability risk assessment approaches are seemed to ignore the impact of risk reprioritization criteria weight and risk behavior of decision makers. Driven to narrowing down such gap, in this paper, decision support model to considering the weight of supply chain sustainability risk criteria and decision makers risk behavior is proposed using integration of Shannon Entropy, Statistical Variance and Prospect Theory. Illustrative example on using the model for practical purpose is presented and followed with potential research directions from this initial effort.
