摘　　要：提出了(指数一指数)型收益函数下二行动决策问题,建立了最优行动和最优决策函数的选取规则,对该模型下的抽样净益(ENGS)进行了研究分析并得到其计算表达式。将理论推证的结果应用于实例的数值模拟计算中,通过图与表展示出决策分析的可视化结果,从而获得最佳样本量以及样本量的上界。The decision problem on two actions under(exponential-exponential)type profit functions is presented.The choosing criteria about the optimal action and the optimal decision function are established.The ENGS for this model is studied theoretically,and the calculation formula of ENGS is obtained.The theoretical derivations are applied in the case of numerical simulation calculation,and the visualized results of the decision analysis are displayed by graph and table,so as to obtain the optimal sample size and the upper bound of sample size.
