Research On Cost Estimate Of The Shipyard Engineering Item And Application

The cost management of the engineering item is pass important to the enterprise, The quality of cost management is direct relation to the economy performance of the business enterprise, even relation to the enterprise's existence and development. The cost control of the engineering item in the shipyard is also an important means to exaltation the competition ability of the enterprise ,in the cost management of the shipyard item, the cost estimate is the premise to cost control, therefore if you want to work well of cost control, you must estimate to the engineering item's cost before ,and then provide emolient guarantee for cost control.because of the shipyard engineering item has a characteristics of changeable and complexity, how to carry on a cost estimate to the shipyard engineering item availably becomes a puzzle of the governor of item construction .This paper is commence on the engineering item cost constitute, and carry thorough analysis on the cost of the shipyard engineering item, resolving the complexity shipyard engineering to regularity single item, and catch the time of impoldering the resources management system of a shipyard, carry on standardization management to the shipyard engineering item, in the system according certain standard to keep the history of the engineering item record every time, for the cost of the engineering item estimate provide emollient of support.The method of estimate is too much, this paper carried comparison on various estimate in common use method, analysis characteristics and localization of each method. Combine estimate object's characteristics to carry on aiming select then can attain the best of estimate effect in the application.The engineering item cost constitute complications, impact factor be numerous and involve a great deal of indetermination factor, give cost estimate bring certain difficulty. This paper connect misty mathematics and index number smooth technique, establishment the misty estimate mathematics mode of the shipyard engineering item cost, verify the possibility of the model from the theories, In the application of the model, This paper still try to carry on procedure design and development to the model, and application in the enterprise resources management(ERP) system, for examination the accuracy of the model provided more emollient practice terrace. Result enunciation that the model has a higher of estimate accuracy.
