The classical newsboy model assumes that the demand is a random variable with known distribution. Base on this assumption, the expected total cost or profit function can be constructed and the optimal order quantity can be obtained by using differential method. However, in reality failure to meet demand is always associated with a specified known distribution. Thus, the above procedure to find the optimal order quantity does not work for the classical newsboy problem. The aim of this research is to relax the assumption and to extend the analysis of the distribution-free newsboy model. The analysis is based on the collection of historical demand information and use nonparametric bootstrap method to estimate the optimal order quantity. In order to evaluate the performance of bootstrap estimate, the relative errors are computed when the demand obey exponential, normal, Poisson and negative binomial distribution, respectively. The numerical results will afford retailers to decide on the optimal order of the basis for decision-making. Ji-Cheng Wu 吳繼澄 2008 學位論文 ; thesis 97 zh-TW
