Abstract:

In the complex equipment development project, it is very difficult to manage the project schedule planning since the complexities and uncertainty characteristics occur throughout the development process. The development process of complex equipment is viewed as a whole system consisting of a series of landmark events based on the idea of the system theory. Firstly, a graphic evaluation and review technique (GERT) network model is designed to describe the complex equipment development project, then the complex equipment development project completion time GERT network “inverse problem” solving algorithm is discussed. Finally, a model is used to solve the expected completion time based on a certain aircraft development project,the result of the example shows the validity of the model.
