以堆场利润最大为目标，建立确定集装箱堆场最优容量的随机规划模型，研究日堆存量的随机变化规律对集装箱堆场容量的影响。通过对比日堆存量分别服从正态、均匀、负指数分布时模型的最优解，得出在吞吐量一定的情况下，日堆存量服从正态分布时，堆场所需容量为最大；而堆场容量相同时，日堆存量服从负指数分布的集装箱堆场吞吐能力最大。

By studying the affection of the daily stockpiles’random variation on the optimal capacity of the container yard,a stochastic program in G Model for determining the optimal capacity of the container yard was established,in which yard's maximum profit was considered as the target. By coparing different optimal solutions of models when the daily stockpiles respectively obey normal,uniform,negative exponential distribution,it’s concluded that in the case of a certain throughput,optimal capacity is largest when the daily stockpiles follow a normal distribution;in the case of a certain capacity,throughput capacity of the container yard is largest when the daily stockpiles follow negative exponential distribution.
