Newsboy Problem with Random Fuzzy Demand
摘要
Abstract
Considering that demand takes on random fuzzy, a profit model under newsboy problem with random fuzzy demand is developed. By means of the credibility measure theory,its expected profit function is presented. Through the analysis of the expected profit function, the concavity of the function is revealed, and the existence and uniqueness of the optimal order quantity are also proved. A hybrid algorithm integrating the random fuzzy simulation and simultaneous perturbation stochastic approximation is designed to carry out the solution to the model. Finally,a numeral example is given to illustrate the validity of the hybrid algorithm.关键词
