供应链的风险测度是对供应链中不确定因素造成的损失进行量化。对供应链的风险测度方法:均值方差、风险价值、条件风险价值进行了梳理。测度方法经历从注重波动到强调损失期望的转变。均值方差对称地处理收益与损失,风险价值只能衡量置信水平与目标水平之间预期的最大损失,条件风险价值关注利润低于某个给定水平的利润平均值。
供應鏈的風險測度是對供應鏈中不確定因素造成的損失進行量化。對供應鏈的風險測度方法:均值方差、風險價值、條件風險價值進行瞭梳理。測度方法經歷從註重波動到彊調損失期望的轉變。均值方差對稱地處理收益與損失,風險價值隻能衡量置信水平與目標水平之間預期的最大損失,條件風險價值關註利潤低于某箇給定水平的利潤平均值。

Supply chain risk measurement is to quantize the loss caused by uncertain factors in the supply chain.The article combs the methods of supply chain risk measure:mean variance,value at risk and conditional value at risk. The methods show the turn from attention to fluctuation to emphasis on loss expectation.Mean variance symmetrical-ly deals with gains and losses.Value at risk can only measure the expected maximum loss between the confidence level and the target level.Conditional value at risk focuses on profit below a given level of average.
