摘要： 综合效益模型，是一种综合多因素影响的动态模型，它既包括一般效益模型，又考虑最优投资的优化效益模型。前者求解，可用解析法；后者求解，就不那么容易。文章分析了模型特征，认为是一个固定端点的最优控制问题，从而，选用格林定理（公式）能较好地求得满意解。

Abstract: The model of the synthetical benefit is a dynamic model which multieffects with various factors. It both includes general benefit model and considers optimal bencfit model for optimal investment, the former can be obtained by analyzed method, the latter is not very eagy to obtain. The paper takes it as an optimal control prolem with fixed end-points judging from analyzed characteristic of model there by satisfactory solution is obtained by using green's theorem(formula).
