Network Planning Techniques In The Actual Project

The network planning is a technology that represents works and the time needed to complete them, as well as the relationships between them with the help of networks. Through network analysis, the research of the relationship between project expense and time limit for a project can be made to find out the critical path in the process of determining plans and in the implementation of these plans. Making overall plans is the main trait of network planning techniques. Because of this, it can arrange some cross-functional project plans containing complex production technology rationally in which there are various projects with close relation between them, such as the development of new product, large-scale project, the repair plan of production equipments and so on. It also can be applied to the arrangement of resources like manpower, material resources, financial resources and the reasonable organization of report form, file flow and so on.The reconstruction of 9000kg tobacco production line in Qujing cigarette factory involves the repair, installation, examination and debugging of those equipments; the disassembly of the building; the construction of pipeline and bridges. Moreover, this project also involves the coordination of different type of workers and various resources, the dispatchment of new and old equipments and construction equipments should also be considered. So the production and economic performance of Qujing cigarette factory are affected directly by the reconstruction of 9000kg tobacco production line, how to complete this reconstruction in the time as short as possible assuring the quality and quantity is the problem needed to be solved immediately.In this paper, through using the network planning technique, the key path is found, then the methods of working procedure decomposition, operating in three-dimensional space, time exchange, and improving the quality of people are used to cut down the time needed in the critical procedures. Finally, the time used in the whole project is reduced by 18%.Practices prove that this method works very well, this reduces the production stress of Qujing cigarette factory and the loss due to the stop of production.
