Based On Ext Hightway Tender System Design And Realization

In order to strengthen the tender management of highway construction, standardize thepre-qualification documents and the preparation work for tender documents, the GuangdongProvincial Communications Department issued " a notice of the Supplementary Regulationsin the implementation of the Ministry of Transport of Guangdong Province," which ishighway engineering standard construction tender documents "(2009Edition),according to itsown characteristics ". This system is developed in this context. The purpose is to safeguardthe development of the highway construction market healthy and steady, vigorouslystrengthen the management of the tender, and establishment of binding mechanism to improvework efficiency. This system is in line with level of the three list standard in Guangdongprovince highway construction tender system and applicable to the operational highwayconstruction project bidding.According to the circular, the highway bidding system is divided into four modules:tender preparation; batch management; system configuration; Tender Offer. The tenderpreparation includes: project management, bidding section division, tender unit input,funding the trial template set, scoring template settings, tender batch management; Batchmanagement mainly includes: batch basis information, pre-qualification, tender list, tenderopening management, reporting functional modules etc;System settings includes: thefunctional navigation settings, departmental management, user management, rolemanagement, role permissions, data dictionary, system logs and other functions; The tenderoffer includes: BOQ, project list, itemized BOQ, generate quotes file, print the tender offerdocuments and other functions.System uses the Java platform application development environment (MyEclipse6.5), theSSH integration framework, principles and application of database technology (SQL Server2008), software engineering and other related technologies, using Ajax synchronous Transferto reduce interface refresh; by adopting Ext as the main control to make the interface moreuser-friendly and beautiful.This system resolves the networking highway tender issues such as standardization,standardization, procedure, which embodies the principle of "fair, open and fair", so thatmanagers can understand each batch or lot tender situation.This system solves the rapidapplication of a variety of templates and ratings of prequalification template in differenttenders tender, List offer and quickly import and export, that changed the past that kind of asection of the tender management mode. In process of invite public tender system,it can automatically generate all phases of the report; greatly reduce the user’s workload, normativeinvite public tender process.
