Model of Third-Degree Price Discrimination in Uncertain Demand and Simulation

The article puts forward a approach of third-degree price discrimination decision of monopolist in uncertain demand,according to the disparity between the existing theory of price of monopolist and their practice.A new decision model was found based on the third-degree price discriminarion decision model in certain demand.Sametime the article gives us a way of solving the decision model by computer simulation.And it analyses the results of simulation,the results show that this method expand the theory of price of monopolist and improve the utilization of the theory as well.
