Analysis And Design Of Scoring System For Highway Project Cost

Highway engineering cost documents audit scoring system is based on the characteristics of traffic engineering cost management of Zhongshan City and it is a system to make analysis and design by selection of the object-oriented methodFirst of all, this paper outlines the project background and problems of the highway engineering cost documents audit scoring system and introduces the significance, importance and current status of this research. After that, in the stage of demand analysis, it makes the analysis on business demand, functional demand and non-functional demand. When business demand is analyzed, its main business processes are represented through the activity diagram; when the functional demand is analyzed, its analysis is made through the use case diagram; As for the non-functional demand, its analysis is made from the aspects of environmental requirements, performance requirements and security requirements. Again, in the stage of system design, the overall design, function design and database design are completed that mainly include several modules such as the formation of cost documentation, audit on the cost documentation, cost evaluation, etc. When the system’s functions are designed, a detailed description of the main content necessary for this paper is provided through the function structure diagram, class diagram, sequence diagram and activity diagram. When the database is designed, the detailed design is done mainly through the entity relationship design and database table design.Finally, a summary and prospect is provided in this paper for highway engineering cost documents audit scoring system...
