Research And Software Developing Of Mechanized Construction Cost Control And Assistant Decision-making System For Road

In recent years, with the fast development of our country economic the government is expending more and more capital on construction especially road-building. This is providing a good opportunity for road-constructors. But the benefit of many constructors is very little even more to the bad at present. That badly restricts its development. So a main problem that many road-constructors are encountering is how to control construction cost in constructing, to reduce cost, to advance quality and increase profit. And it is just the motive of writing the article. Because the proportion of mechanical cost is about 30% becoming bigger and bigger with using more machines in construction and its change is also the biggest in total cost, it is the main factor influencing the total cost. The article mainly discussed how to control mechanical cost better to reduce the total cost.The article analysed and researched the cuurent status of road-constructors and cause of formation, structure, characteristic and factors of construction cost. And demonstrated the key of controlling construction cost is to control mechanical cost. Then setted up the monitoring model and the controlling model of construction cost integrating profit and loss theory to control cost. Profit and loss theory is an effective and precise method of controlling cost that based on cost and progress. Adopting complication analytical method to analyse the factors of the cost difference in detail and build model. The emphasis is on the control and analyse of mechanical cost. At last the article maked the system of construction cost management and accessorial decision based on the analytical model of cost difference and the demand of road-constructors with Microsoft Visual Basic 6.0. At the same time, it provided the analytical example. The system is not only to collect, to deal with, to pass and store information of construction process in time in order to pass the actual information of construction cost to managers but also help them to make a decision. The interface of system is very friendly. It is easy to study and operate too. And it is practical significance.
