Abstract: In view of the logistics demand that cargos are not always needed to send at the first time, merchants should design and offer suitable service. Based on typical operations management practice, using cargo space booking optimization problem as an example, this paper put forward a new kind of newsvendor model that demand can be extended to meet. Upon reviewing the previous research on newsvendor model systematically, this paper analysis its similarities and differences to the basic newsvendor model and the key difficulty to solve, discuss the existence and uniqueness of the solution, explore a approach through which this problem can be translated into the basic newsvendor model, build “Newsvendor-Dichotomy of Bolzano iterative algorithm” to solve it, validate its correctness and effectiveness with double numerical simulation by training and test dataset. The important value of this paper is that it proposed a new kind of operating model for demand management: For stochastic demand which can be extended to meet, “demand stocking” can be realized by offering compensation, the demand and supply can be well utilized bothly, the server and consumer can reach win-win and the social welfare can be promoted.
