Study Of Pricing System For Construction Products

Based on the three-in-one integrated theories of resources allocation to construction industry ,the pricing modes and price formation of construction products , the new price formationmode of construction products has been systematically studied from two angles associatedwith competition character of resources allocation and integrity character of competitive bodywho takes part in competition in this dissertation. The main contents are summarized asfollows.Firstly, beginning with the analysis of the theories of price, construction economics, systemsengineering ,artificial intelligence, the dissertation endeavours to reveal the problems ofcurrent price formation mode of construction products. Through the analysis of the basisof price formation and influencing factors of construction products, the relationship betweenresources allocation to construction industry and price formation mode has been revealed.From the aspect of competition , the current price formation mode can be divided into twokinds. One is the construction budget formation mode associated with quantity adjustment andthe fixed budget formation mode associated with mixed adjustment. The other isquota-controlled formation mode associated with competitive bidding adjustment in resourcesallocation . The quota pricing mode step by step is fit for these formation modes. Somedrawbacks are revealed in these three price formation modes from view of market function.Secondly, according to the principle of resources allocation, quantity-controlled andmarket-driven price formation modes of construction products are designed from the aspect ofintegrity character of competitive body for resources . Their formation modes, fluctuationand adjustment are in total accord with market economic system. The implementation of thenew price formation modes can lead an effective operation : market fluctuation driven bygovernment, pricing system controlled by market, resources allocation directed by the priceformation mode. In the basis of the research including the bill of quantity pricing mode, baseprice of bidding ,bid price and the comparison method of bid price, this dissertation proposesin connection with the price formation that quota allocation to construction implementingenterprises, the price information management of construction products, and development ofengineering consulting lines should be encouraged.At last, a fuzzy neural network based on genetic algorithm has been used inforecasting model of construction products subordinate price system. The first stepis that composite system is divided into several simple systems which can beforecasted easily. The second step is to use a new coding mode in optimizing fuzzynetwork structure parameter focusing on the problems, incompleteness ofmembership function and inconsistence of fuzzy sets semantics. The result from acase study is encouraging.
