| For businesses, the cost of the project management is a problem can not be ignored, the state related to the business of cost management has a good economic development, but also a serious impact on their long-term survival and development issues. In order to improve the market competitiveness of the shipyard, which focuses on the project is to do what cost control. To do a good job cost control, in shipyard project cost control system, the premise is the cost projections. To do a good job of cost control, the cost of the project to predict, will be able to provide good protection for cost control. Shipyard projects are usually complex and variable, therefore, project managers need to focus on resolving the question is how to predict the cost of the shipyard project.Constitute the basis of the cost of the item from shallow to deep analysis of the costs in the shipyard projects, complex projects into small projects with certain rules and shipyards to carry out MIS system development opportunity, standardized research the shipyard project in the system, in accordance with the established law of records each information as a basis for follow-up project cost forecast data.Predicted a wide range of advantages and disadvantages of both, this article comparative analysis of several common forecasting methods, and a list of its own advantages and disadvantages, in the case, in accordance with the predicted characteristics of the object targeted selection prediction methods cause the results to achieve optimal performance.Constitute the cost of the project budget is very complex, which contains a large number of influencing factors, there is a lot of uncertainty factors to consider, therefore, difficult to forecast costs also increased. This article on the basis of the exponential smoothing method and fuzzy mathematics theory, build a repair shipyard project cost projections fuzzy predictive mathematical model, and the feasibility of the model made a validation of the theory. |
