WebJan 25, 2024 · The risk-aversion in an inventory problem has been introduced in papers (Chen and Federgruen 2000; Choi et al. 2001) by means of mean–variance models and in Luciano et al. ( 2003) by using the value-at-risk (VaR) as a risk measure. WebIn this paper, we use CVaR as the risk measure. The objective of the traditional inventory problem is usually to minimize the inventory cost and to consider risk in a multi-period inventory problem; previous studies usually take a single-objective approach.
