By using the computer simulation method, the newsboy problem was studied, and the amount of subscription which makes the expected loss of the newsboy be the smallest was worked out.

This paper discusses optimum order quantities and expectation profits of each member in newsvendor cases for three kinds of supply chains: integrated control,dispersed control,and vendor managed inventory(VMI) without any coordination.

A newsboy model with budget cost constraints;

Then,a newsboy model is developed by analyzing the optimal decisions in view of both the cooperation and non-cooperation,as well as a gaming model to reflect how the randomly disturbed market demand affec.

Based on the newsboy model for price discounts,the bended price-demand curve for distributors is analyzed.

Reordering newsboy problem with stochastic-fuzzy parameters;

According to the ignorance of price competition,facing stochastic price-dependent demand,a demand model based on the newsboy problem is proposed.

On E-procurement Strategy Based on the Newsvendor Model;

The paper consider the newsvendor model where demand distribution is endowed with unknown parameters,and prove that the traditional approach of replacing parameters by their estimates will make the newsvendor away from the optimal profit level,leading to a suboptimal result.

This paper considers a newsvendor model where the retailer is risk averse and his capacity is constrained.
