Development Of The Cost System Of Water Conservancy And Hydroelectricity Engineering

With the implementation of the tender offer and tender bidding system in Water Conservancy and Hydroelectricity Engineering (WCHE), projects cost shall be estimated in time by a designer and a contractor in order to work out the tender and the quoteprice. Therefore, development of the cost system of WCHE is a significant work, at the same time, is a quite hard one. To the cost system of civil engineering, due to complexity and inconstancy of WCHE, study of the cost system of WCHE is more infantile and tougher. It is emergent for us to develop the cost system of WCHE which has wide applications and is operated simply.Based on the mastery of the method for working out cost of WCHE, the author analyze the structure of cost of WCHE emphatically, then, object-oriented analysis, and object-oriented design, and object-oriented programming for the cost system of WCHE are processed with the method of the object-oriented software engineering, and the cost system of WCHF in operation simply and in wide use has been developed successfully on the flat of Windows, at last, the system testing is carried out, which indicates the system runs stably and the results meet the related requirements.The cost system of WCHE has the merits as follow:1. The visibility of the ration databases ?The construction and the installation ration database, the materials database, the construction machineries ration database and the equipments database can all be examined, modified and expanded directly in the databases;2. The simplicity in operation ?During the course of the working out a cost of WCHE, all work can almost be completed just only with a mouse (except some inputting of the project-quantity and the necessary notations) ;3. The precision of the results ?Automatic calculation for the cost sheets of WCHE is designed according to relevant regulations, which insure the precision of the results;4. The standard of reports printed ?The format of reports printed of the system is consistent with the regulations of the documents of cost of WCHE, and the reports are adjusted theirs layout automatically in the pages, so the layout of sheets printed by the system are reasonable.The system has been tested strictly, and tens of costs of WCHE have been completed with it, so, it is stable in operation. It takes only several hours to complete a cost of WCHE with the system, while the same work had to be completed in half month, even one month without it in the past In addition, the efficiency of the work and the veracity of results have been improved largely. The level of working out cost of WCHE has been improved to a new standard with the emergence of the system.
