The Design And Implementation Of A Queuing And Calling System In The Tax Service Hall

The author is in charge of business processing and daily management in the tax service hall at a local taxation bureau. In every workday, several thousands of taxation-related business need to be processed in the tax service hall. In other words, the workload in the tax service hall is relatively heavy. How to serve the taxpayers swiftly and orderly, and enhance the efficiency of tax-processing has been a question haunting the author.Although the queuing and calling system is already accessible in the author’s unit, this system still shows certain deficiencies, such as single calling mode, and the impossibility of dynamically adjusting the type of business through the service window or querying non-taxpayers’ number in the line. In accordance with questions existing in the current queuing and calling system, the author applies the accumulated theoretical knowledge and development technology of software engineering in the design and implementation of a queuing and calling management system. This system can dynamically adjust the type of business through the service window in the tax service hall in light of the volume and type of business.A solution of reasonably deploying manpower in the tax service hall in the arrival of massive business is provided in this paper. First of all, business is classified, and those that generally consume a longer time are screened out as complicated business. By setting up two threshold values(α and β) for complicated business, the type of business that can be handled through the window is dynamically adjusted. In other words, service windows, in which the treatment of complicated business is exclusively available, should be added. Furthermore, in light of the practical condition of the volume of complicated business, whether extra manpower(available and unavailable service windows) and how much extra manpower should be added to handle the business can be determined. Hence, a balance between the volume of business to be handled and the investment of manpower can be achieved.With the purpose of implementing the above-mentioned queuing and calling mechanism, the system is analyzed, designed and implemented. First of all, the functions and performance requirements of the system are analyzed. Next, the queuing and calling mechanism is designed and discussed, and the business framework of this system is designed. Moreover, the functions of the various constituent parts in the framework and the controlling relationships among them are introduced. The algorithm utilized in each constituent part for the implementation of the mechanism is specifically designed. The software framework of this system is designed. By virtue of hierarchical model, the software is divided into four hierarchies, namely, graphical interface, business logic, model and permanent storage; the function modules of the system are divided into six parts, namely, queuing, query, number allocation, number calling, window allocation and tax officials’ management.; the tangible type, data access type and database in the system are designed. Under the support of.NET Framework 3.5 Foundation Class, Visual Studio 2008 integrated development tool is utilized in the development. C# programming language is applied in this paper, as well as ASP.NET as Web programming language, and SQL Server 2008 as database management system.After the implementation of this system, test cases are designed to test the system and to correct the mistakes found in the test. Currently, the system is able to operate stably, and to automatically change the scope of work in the service window through the volume of complicated business.The queuing and calling system designed and implemented in this paper solves the questions existing in the original system, transforms the single mode of queuing and calling, and provides a self-adaptive mechanism which can automatically adjust the service window in light of the volume of complicated business. By means of the two-dimension code on the list, users are provided with an interface, through which they can query information about the line. The objective of design is realized through the system. Through the trial application, satisfying effect is achieved. The objective of further work is to implement an even more exquisite queuing, calling and window-adjusting mechanism based on the type and volume of business through the mining of data in the previous queuing and calling logs.
