Design And Realization Of Cost Analysis And Freight Prediction System For Marine Transportation Of Fuel Coal

With the increasingly demand of scientific decision-making, how to make s-cientific decision according to the changes of the market must combine with the scientific means.As an important energy enterprise,power company plays a very important role in power supply.The way of shipping is to sign the transportation contract with the ship company to decide the freight and terms of the contract, which has to be negotiated,and will take a lot of human and material resources. Therefore,freight fluctuation is the biggest problem the enterprise faces,and study on the freight formation mechanism can reduce the risk of changes,enhance the company competitive advantage.In this paper, Struts,Hibernate,JSP and other sophisticated technologies are used to develop cost analysis and freight prediction system for marine transporta-tion of fuel coal. First of all, I have analyzed the problem of transportation cost control in the company. Then, combind the actural needs of Power Company, I design the system.According to the conventional information system development process, this paper gives the detailed analysis program and the implementation p-rocess.The system is mainly divided into four parts. (1)Users management module is used to add and delete users,responsible for the security of the system access control form the level of users; (2) Cost analysis module estimates the specific ship operating costs; (3)Freight prediction module use quantitative model such as brown single parameter linear exponential smoothing method,seasonal exponent-ial smoothing method and ARMA model, at the same time,combined with qualit-ative prediction to predict and analyze the domestic coastal transportation market freight,instruts the power company to rent ships; (4)Log management modules get the record of the login, operation, logout of all users; guarantee the security of the system.
