The conditional value-at-risk model is an important tool in risk man-agement. This paper studies a multi-loss conditional value-at-risk model with upper
and lower decision-making. We introduce the concept of -VaR loss value (minimumvalue at risk) and -CVaR loss value (minimum risk value orresponding to the loss of value of the conditional expectation or conditional value at risk measure) of a multi-loss function based on the weights. We propose a bilevel multi-loss conditional value-at-risk model based on the weights. The objective is to find out an optimal solution to the model of upper level and lower level value of multi-loss -the CVaR’s based on the weights. We show that it can be solved more easily through another bilevel programming model to obtain the optimal solution. Finally, we give a bilevel conditional value-at-risk model, including pricing and ordering of a supply chain to manufacturers ad retailers on a product model calculated the minimum wholesale price of oversupply and shortage of risk minimization under the manufacturer and retailers excellent order amount.
