Unlike existing models where development stages to be modeled usuallydetermined by model structure, array application in the model of this paper makes itflexible and easy to model software development projects with different stages.

• 数组的运用使模型使用者可以根据需要把开发过程细分为不同的开发阶段,并运用模型方便灵活地对多阶段的开发过程进行模拟,而现有的关于项目管理的系统动力学模型一般都是在模型结构中就规定了模型所能模拟的开发阶段。
