摘要
研究了单周期报童模型的零利润与亏损风险问题。在平均利润为零的情况下衡量风险时,采用半方差方法来进行分析并与方差度量风险的模型比较,用半方差方法得到报童模型的最小风险小于后者。
The question on null profit and loss risk in an odd period of newsvendor model is studied in this paper.The result shows that the minimum risk obtained by a semi-variance method in a newsvendor model is smailer than that obtained by the model of an variance measurement risk under the null averige profits.
