The Study Newsvendor Model And Supply Chain Contract Based On The Mean Variance And CVaR Risk Standard

In recent years,the newsboy model is a hot issue in management science.We mainly focus on the newsboy model based on the 020 in business,wholesale price mechanism and price subsidy mechanism supply chain model The main research contents are as follows:With the rapid development of mobile Internet,more and more retailers to join the mobile Internet platform for sale,we study its optimal decisions for the optimal order quantity with the help of the newsboy modeLThe ordering strategy is presented in three cases:offline sales,online sales and hybrid sale of the above two.our results show that under the same conditions of market demand distribution,the distribution of service channel and online service channel are the least,and the fluctuation of market demand is higher,and the optimal order quantity of retailer is also more.In the wholesale price mechanism,we study two cases:the neutral retailer and the risk-averse retailer.For the neutral retailer,by the mean coefficient of variation we obtain the retailer’s optimal ordering decision and the expected profit of the retailer,manufacturer and the whole supply chain,in addition,we also get that verification of the special distribution function.Forthe risk averse retailer,we get the retailer’s optimal ordering decision the CVaR value of the retailer’s profit and the expected profit of the manufacturer by means of CVaR method.Finally we study a example of a cloth-company sales supply chain,and obtain the retailer’s optimal order quantity with surplus value and the changes of the second-purchasing price,and get the expected profit of the supply chain with the changing trend of the wholesale price.In the situation of the price subsidy mechanism,risk neutral retailer,assume that the retailer receive per unit of product values and manufacturer give price subsidies,for each unit of unsold products from the supplier at the end of the season,we get the optimal order decision of the retailer.If the the retailer is risk averse,we give the retailer’s optimal ordering policy by the CVaR risk measure criterion.Finally,an example is presented by considering a clothing company,we give and compare the optimal ordering decision of the price subsidy mechanism,and the expected profit of the retailer,the manufacturer and the supp6y chain.
