With online platform emerging, probabilistic selling(PS) has been widely applied in Hotwire and Priceline. The seller packages two kinds of heterogeneous products into probabilistic goods by appropriate proportion as well as sells to consumers via online. Firstly, by means of consumers' evaluation differences for goods, the heterogeneous product dual-channel selling model(HDTM) is constructed, and its optimal pricing strategies and optimal profits are analyzed. Furthermore, the heterogeneous product dual-channel probabilistic selling model(HDPM) is constructed similarly, and its pricing strategies and optimal profits are also discussed. Finally, we analyze the differences between the models’ profits as well as the impacts of probabilistic selling to their profits. Furthermore, an illustrative example is given, the results show that HDPM profits for the low and high levels have outweigh advantages, that is “two ends advantages”, but the profit of HDPM for the moderate level is lower than the traditional selling model’s profit.
