The Design And Implementation Of Coal Quality Information Management System

The level of coal quality, matters not only for the Using Effects and product quality of coal enterprise, but also for the reputation and economic benefits of coal enterprise. In recent years, the sales process with the pricing of coal sales policy changes, the transaction process in disputes from the "price game" to "quality game". In order to solve the two parties identified differences in coal quality, find a feasible and effective, and the parties to the transaction are recognized method of measuring the quality of coal in recent years is the end of the coal industry.Pingmei Group launched a "the model of quality control of coal sales", In this paper, based on the topics Put forward the coal quality information management system through the computer software acquisition, storage and management of coal sales process both sides of the coal quality test data, paper first analyzes the architecture of the system, determine the system objectives, and given the system's functional modules。Main function modules include:coal mine information management, customer coal quality information management, quality checks, integrated query, decision support, user management and other ancillary functions. Paper Gives the system the core business process logic diagram, and three-tier architecture introduces based on.NET system, and system's security design strategy. Defined 6 view and 7 stored procedures and related datatables in the database design. Finally use.NET platform and C# technology to achieve the system's main functions.the paper analyzes the presentation layer, business logic, data access layerand implementation of key technologies, focusing on the coal quality test data, calculation and validation, mines, and customer confidence based on the quality of clustering classification, dispute warning The division of responsibilities and so on. automatically determine the credit rating of each month of Parties to the transaction, and according to long-term accumulation of the results of coal quality information to determine the credibility of parties to the transaction.The system in practice to the greatest degree of coal quality test results to ensure the impartiality and objectivity, to ensure the effectiveness of market mechanisms. Parties to the transaction process of the coal trade on the coal quality test information input, calculation and audit, according to business circumstances, generate reports to meet the needs of all types, empirical formula based on the dynamic formation of the screening and comparison of the reduction of subjective factors on the coal quality testInterference.
