Research On Quotation Technologies And System Of Fiberglass Boats

Fiberglass boats offer which plays a vital role for the healthy development of enterpries, is a very important part in production and operation of the fiberglass boats enterprises. This paper researches the fiberglass boat construction cost components, analyzes the similarity of fiberglass boats offer terms, proposes three methods of fiberglass boats offer, and has developed a computer-aided fiberglass boats quotation system using the database technology and Java language development tools.The construction of fiberglass boats cost components and cost estimates were analyzed firstly. The construction costs of fiberglass boats consists of body costs, outfitting costs, marine costs, electrical communication costs and so on. A new fiberglass boats cost estimate is achieved by using BP neural network.In the similarity analysis of fiberglass boats, the similarity factors and weights of each factor are defined. Use of hybrid similarity measure establishes a similarity model of fiberglass boats.Three quotation methods are proposed in the studying of fiberglass boats quotation. The methods are based on the mother-boat's fiberglass boat fast quotes, statictics quotes based on boat ower requirements and fiberglass boat quotes based on BP neural network, and analysis of the characteristics and application scope of the threee quotation methods.Finally, accrording to the practical application background of Weihai Zhongfu Xigang Ship Co.,Ltd. , the development of a systematic needs analysis, systems functional model and data model analysis, and architecture design analysis are carried out. A computer-aided fiberglass boat quotation management system is developed based on the analyzing of fiberglass boat quote method, fiberglass boat building cost and similarity measurement methods of fiberglass boats. At last, using the quotation cases of Weihai Zhongfu Xigang Ship Co.,Ltd. example the accuracy of the computer-aided fiberglass boat quotation management system.
