WitrynaAbstract. The newsvendor problem is one of the most basic and widely applied inventory models. If the probability distribution of the demand is known, the problem can be solved analytically. However, approximating the probability distribution is not easy and is prone to error; therefore, the resulting solution to the newsvendor problem may … Witryna26 paź 2015 · Consider the newsvendor model, but under the assumption that the underlying demand distribution is not known as part of the input.
