在复杂装备研制项目中,由于其研制过程中的多种复杂性和不确定性特征使得对项目的进度规划管理非常困难。文章基于系统论的思想,把复杂装备的研制过程看作是由一系列标志性事件组成的整体系统,定义了复杂装备研制项目的图示评审技术(graphic evaluation and review technique,GERT)网络模型,讨论了复杂装备研制项目完成时间的GERT网络“反问题”求解思路。以某飞机研制项目为例,对其期望完成时间进行了规划。
In the complex equipment development project, due to the complexity and uncertainty of its development process, the project schedule management is very difficult. Based on the idea of system theory, the article considers the development process of complex equipment as a whole system composed of a series of landmark events, defines the GERT network model of complex equipment development project, Discusses the GERT network “inverse problem ” solution ideas for the completion of complex equipment development projects. Taking an aircraft development project as an example, the expected completion time is planned.
