Research, Large-scale Project Management Information System Based On The Wbs

In huge engineer project, the long duration, so many departments involved and the variation of various factors baffle the implementation of engineer project, so the traditional management method can't fit the modernization management.In this paper, through the advantages of network and information technology, writer establishes WBS-Based Engineering Project Management Information System in which is based on the theory of engineer project life cycle. Information systerri is an important method which makes project management become scientific and modern. The Engineer Project Information System could realize the integration of functions including scheduled plan, organization, schedule control, communication under the computer network environment. Information could also be fully shared and effectively transmitted during the whole life of model development and the performance of project management can be improved.Firstly, the paper analyzed the characteristics and the life cycle process of Engineer project management. The framework of Engineer Project Information management System was proposed based on the body of project management knowledge. Secondly, the structure of WBS was analyzed particularly, and the storage method of WBS was researched deeply, base on the study discussed, that the WBS was deposited by XML document with Object-Oriented Programming was proposed; Thirdly, based on the WBS, the method of double code network diagram drafted by computer automatically was developed, and the adjoining matrix of double code network diagram, the Method of Auto Adding Virtual Working Procedure, The Method of Numbering the Node of Dummy Arrow and The study of the algorithm of the function in arranging dots was realized; at last, based on the extending-construction engineer project of Shan'xi Airport Management Group, the customers' requirement was analyzed strictly by UML , and the function model of engineer project management information system was designed , the key code of WBS's realization was also proposed.
