Research Of Structure Frame Designing Of Shipping Intelligent Transportation System

Inland shipping system plays an important role in our country's society and economy as well as in our transportation system. Compared with other kinds of transportation methods, inland shipping system lags behind others. As an advantage transportation method, Inland shipping system needs less land, produces less pollution, consumes less energy but carries more goods. With fast development of highways and railways and integrated transportation system, inland shipping system faces much more challenges right now. Inland shipping industry's general profit and efficiency are becoming lower and inland shipping system's resource is not yet exploited yet, and its competency goes lower than any other transportation system. The development speed of inland shipping industry is limited, and the market share of inland shipping industry in society gross goods transportation is less than ever.Compared with foreign inland shipping system, our infrastructure of inland shipping is very bad, and its productivity is much lower. Our inland shipping industry is just at a lower level. From the experiences in developed countries, inland shipping system can not be replaced by any other systems and is an important transportation method in any developed country. And multiple transportation systems can be coordinated and develop well.In order to avoid redundant construction and foster competition, it is very important to research inland shipping transportation system. Above all, research of management structure of the inland shipping system is the most urgent and important.This paper is based on a research fund "Analysis and Design of Inland Shipping System Frame" which is undertaken by me. An intelligent Inland Shipping System is first proposed in this paper, and the inland shipping system's frame and structure is analyzed. Then the frame and structure of the intelligent inland shipping system are exploited further and proposed based on structure model method from system engineering. The structure model of intelligent inland shipping system is designed. According to logic functions of the system and the fuzzy relationship of logic structure and physical structure, the physical structure and application scheme of the intelligent inland shipping system is determined, which reveals how system functions are deployed in physical system and equipments, and mapping relationship from logic structure to physical structure. And then an integrated system of the intelligent inland shipping is discussed and developed, the integrated system which combines with many other useful systems provides the shipping administrators an comprehensive platform which is based on an comprehensive monitoring system with GIS. The platform can operated certain tasks automatically if it is set well and this can meet the goal of modern inland shipping transportation.There are some research highlights and creative ideas:(1) A structure frame of Shipping Intelligent Transportation System (SITS) is first proposed and discussed in this paper. The structure frame of SITS is composed of several sub systems which are clear in logical relationship, connected with different physics and operated easily. And the frame provides a base for design, implement and management of an application system.(2) According to the actual requirements of inland shipping transportation, the structure frame of SITS is discussed further with a systematic structure model and a structure model of the frame is presented. Meanwhile the design method of structure frame of SITS which was once constrained by data flow diagram and natural analysis is replaced by formalization and quantitative method, and the research method is expanded.(3) The logic structure of frame of SITS is decomposed by the method of fuzzy clustering in functions. There are a lot of basic processes, compound relationships in SITS which is beyond human's ability when the system expands. Then an automatic logic organization and structure method is needed in system analysis. This paper presents a system decomposition approach which can cluster according to relationships and the resulted functional units can be handed out easily because they are tightly connected internally and less connect externally. This decomposition supports the mapping from logic structure to physical structure and decreases the difficulties of the system design. The DFD of inland shipping system is described which testifies the validity of this approach. (4) An optimized design approach of mapping from logic structure to physical structure is proposed in this paper. The design of physical structure of SITS frame consists of four phases: concept design phase, constraints clearance phase, scheme decision phase, and design optimization phase. Because the appraisal and selection of schemes is a key problem which will affect the design goal and system performance, quality and cost, the scheme of inland shipping operation and organization is analyzed by a trial where a decision model of shipping operation and organization scheme is built and it is testified by statistic data.(5) An integrated concept of SITS frame is presented in this paper, where general structure of the integrated SITS frame is discussed and the integrated system consists six departments: Integrated administrator, Integrated database, Comprehensive monitoring system based on GIS, Application software system, Equipment connection deputy and other systems connection deputy. And the comprehensive monitoring system based on GIS is developed in this paper. The integrated system of SITS can solve systematic communication problems, compound operation problems, application expansion problems and compatibility problems, which will lead fast development and application of SITS.The approaches of this paper which will benefit frame design of inland shipping transportation from practical method to scientific and optimized method can be used in many other fields. This paper provides importation resources and a reference for future planning and construction if inland shipping system.
