Simulation And Analysis Of The Construction Process Of Harbor Engineering

For their complexities and randomicities, it is hard to accurately obtain someimportant parameters, such as the time limit and density of haulage, in designing ofconstruction for harbor engineering with conventional method, and then say nothingof the comparison of multi-case. The technique of system simulation is an efficientmethod to deal with this kind of problems.Firstly, this paper describes the process of service numerically, based on thesystem simulation theory and the stochastic service system (the queuing theory).Secondly, based on traditional research of random Circle Operation Nerworksimulation theory, numerical analysis of high tide construction is made andprogrammed, the conditionality of tide in construction is shown. The seasonalinfluences on the construction time are well considered in the simulations.Finally, this paper makes system analysis of Tianjin Port Beida breakwater (thesecond phase) engineering. The single prefabricated process of semicircle componentand the whole construction of breakwater are modeled, by using random CircleOperation Nerwork method. Quantitative analysis of the restrictive relations in theengineering construction is made;and the reasonable equipments set and thecorresponding construction time limit is discussed.It indicates that the application of random recurring network simulation methodcan make a quantitative analysis of the complex influencing and restrictive relationsbetween working procedures and equipments. And it is possible to reasonablyoptimize working procedures and equipments set. The application to a practicalengineering shows the validity of the idea and the efficiency and practicability of thesoftware.
