Abstract

Newsboy problem, as the famous and basic model in stochastic programming, has numerous applications. Completely known probability distribution for random demand is a basic hypothesis in classical Newsboy model, but this is almost impossible to achieve in practice due to that the probability distribution is generally determined by some approximative methods such as statistical inferences and expertise. Newsboy problem with fuzzy probability distribution is studied in this paper, and two-stage stochastic linear programming model with recourse is set up. Improved L-shaped algorithm is designed to solve the problem. Numerical example demonstrates the feasibility and efficiency of the algorithm.
