| This paper simulates the construction of the breakwater with bucket foundation, basing on the theory of recurrent network simulation. The construction of the breakwater with bucket foundation consists of several relating factors, such as equipments, material, supply and demand, technics and administrators. The imbalance and disturbance of these can both make the system inefficient and uncertain. Especially, it may dose bad to the whole project and the relating cost and duration. Before the start of all the actual work, the recurrent network simulation can design these steps of the project construction and simulate their action, which according to the exact project construction condition and engineers'experience in order to take examination and optimization. This paper takes the construction of the extension of the north breakwater in Tianjin Port for example, simulating its construction with the recurrent network method and systems analysis to demonstrate the feasibility of this duration. Through the simulation of several supporting programs, the paper researches the reasonable supporting and working facts for this project. |
