The Analysis And Optimizing On The Logistical Model Of FCG Port In Guangxi

With the development of international economic trade, more goods have strengthened the exchanges of trade through the connection between the ports. International trade port has entered a brand-new era. Because of the growth of international trade and development at full speed of the circulation of materials, as a important transportation pivot, port increases its transport goods and materials total amount greatly, and also the port output has increased too.It is extremely urgent that port should play the main role in developing hardware and software. Its main goal is to adapt to the port the development that is transported. But the actual conditions based on our country, it will cost generous manpower, material resources and financial resources of the port to build hardware .In a short time, it is strengthen to develop hardware to satisfy the demands that is not enough. So, the software needs to be developed greatly. From the existing software state of port of our country, how to improve production efficiency, to reduce production cost and to raise benefit level seems extremely important right away.It is become a restrict bottleneck, especially the inner circulation of materials of port. This has been become more and more important as important link between the trade and port. How can utilize existing resources in the harbor to enable goods and materials to pass the port fast rationally and to load ship is the core of this text that has studied.This text proceeds from real angle of Port of Fangcheng(PFC), has studied the resource distribution within PFC, the abundant and rational existing resource advantage of PFC. Through setting up the optimization model of the circulation of materials, it optimizes transportation direction, transportation time limited, transportation way and transportation structure of the goods and materials. In case of not increasing construction investment of the foundation, it taps the latent power through the inside, utilizes the advanced technological means, and meets the existing demands of circulation of materials.It has set up the circulation of materials after optimizing models. Whensolving the model of optimizing of the circulation of materials, it will meet circuit of circulation of materials, system variable, systematic parameter problem etc. Because of too much system restrain terms, thus will slow down the calculation, calculate precision will be lowed, even more it seems to be has no dealing ways at all when meeting some problems. So, this text is sets up a mainly node. The node, which supposes a fictitious circulation of materials, can solve this problem, while meeting so many circuits of circulation of materials. The handling capacity checked is infinitely great, and it's expenses which passes through the model is zero. Based on this supposing, it is defined as we called" fictitious a bit ", which it is set up, fictitious can level the circulation of materials of harbor a bit, can reduce greatly circuit that circulate, achieve circuit optimum, minimum cost reduce and gain profit optimum purpose. After simplifying the circuit, it can appear with dynamic planning method system, in order to reduce all expenses of circuit and every corresponding rate of circuit to get every berth to unload. Then the short rate of circuit regards linear programming calculation parameter of method as most, thus can make the systematic variable count and reduce them greatly. It is meet with linear programming method various kinds of restrain terms from restrain from and quality system of request overall optimum to get maximum benefit and then.This text that has studied in the system resolve of the train of thought and method, is feasible through the theory and practice identification. With optimum and minimum expenses of circuit, the establishment is adopted to " fictitious " and the solution of reducing the variable parameter.
