針對現有壟斷廠商定價理論與實踐之間的差距，提出了一種需求不確定情形下的壟斷廠商三度差別定價決策方法，以需求確定性下的壟斷廠商三度差別定價決策模型為基礎，建立新的決策模型，并利用計算機模擬和仿真技術求解決策模型。演示系統過程和結果表明，該方法擴充了現代廠商定價理論，增加了現代廠商定價理論的實用性。

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.
