The Research Of Offshore Engineering Project Planning Technology Based On Neural Networks

Offshore project planning is the basis of project implementation,which should be accomplished before the start of the project so that the project can be carried out effectively under the guidance of the schedule. Study found that there is a common problem in domestic enterprises that the plan cannot be used to guide implementation and become a mere formality.The most important reason for this is that offshore equipment project planning is quite difficult because of its characters such as long duration,single or small batch production,EPC general contract,cross-professional,cross-departments and even cross-enterprise project work etc. As a result, the plan usually cannot be finished before starting construction. The planning of project can be considered as a kind of decision-making problem. As is known that artificial neural network has a good performance in the application of intelligent decision system.Hence, the key issues which restrict the efficiency of the project planning are studied in this paper, and a method of offshore project planning based on artificial neural network has been proposed, which can promote the construction enterprise to improve the level of planning management.Firstly, the research on the project planning technology and its application in the field of offshore project both at home and abroad are analyzed and summarized; Secondly, the principle of artificial neural network is introduced briefly; Thirdly, the key issues which restrict the efficiency of the project planning are found through detail analysis of the techniques of offshore project planning; Fourthly, two of the key issues: WBS and sequence the activities are proposed. Aimed at solving the WBS problem, the WBS model of offshore project is built and a modular neural network model used to solve this problem is proposed;Aimed at solving the project activities sequencing problem, the sequence model of offshore project activities is built and a method based on BP neural network is proposed; Last, by adopting the Spring development framework and B/S structure, the prototype system of the project planning management system is designed and developed, which prove the feasibility and validity of the approach.
