Structure Design of Shipping Intelligent Transportation System based on Fuzzy Clustering
Shipping Intelligent Transportation System (SITS) is a large scale and complicated system with various factors and the essential of SITS is to fix on the mapping relationship between logical and physical architecture. SITS consists of two types of elements; one type of elements is the elements with logical attribute which are the functions of SITS and another one is the elements with physical attribute which are the subsystems of SITS. In order to reduce the complexity of the system design, a disassembly method about logical structure based on the fuzzy clustering is introduced. The relationship matrix, relationship intensity matrix and its reachable matrix between the function set and the subsystem set are built in this paper, and then the system structure is established. 10 subsystems and 19 function domains are chosen as the design elements in a case test where physical subsystems are reallocated by principles of SITS structure design and the fuzzy cluster. And a physical subsystem partition which is the foundation for implementation of SITS is obtained in the end.
