The invention discloses a
bridge engineering bidding and bidding quotation risk early warning and cost dynamic regulation and
control system and method. The
system comprises a
data acquisition module, a data preprocessing module, a risk early warning module, a cost dynamic regulation and control module, a linkage execution module, a data storage and update module and a man-
machine interaction module. On one hand, a multi-dimensional
data acquisition system of bridge exclusive basic data, market
dynamic data, policy and regulation data, bidding
transaction data and construction pre-judgment data is covered, cooperative operation of static feature risk association factor extraction and dynamic
time sequence risk change trend capture is realized, and the accuracy of
risk assessment is improved; and meanwhile, a risk-cost closed-loop linkage mechanism is established, a cost-risk association
database is constructed, and differential cost regulation and control strategies are formulated in combination with management and control targets of different stages of bidding and tendering, so that the technical problems of low regulation and control efficiency and poor adaptability are solved.
