Function graphic modeling technology and its application in road & bridge construction

Modeling technology is the key to the advancement of road & bridge construction problem solving technology. In light of the existing defects of problem-solving modeling technology, a new function graphic modeling technology which can reflect problem solving characteristics is proposed. Based on function graphic object which has engineering properties of length-variable and unstructured, and can exist independently and work cooperatively with each other, a group of function graphic objects are used to emulate planed road & bridge construction sub-problem, and solving process is carried out interactively and dynamically by creating, operating, and deducing function graphic objects. Through the proposed function graphic modeling technology, the traditional modeling method and realization model of road & bridge construction problem solving are broken through, and a new modeling and realization technology system which is suitable for solving characteristics of road & bridge construction problem is set up.
