摘要
提出了铁路智能运输系统 (RITS)的两个本质特征———开放系统结构和分布式智能系统结构。首先描述了铁路运输系统中环境与任务的复杂性 ,正是由于铁路智能运输系统目标的多样性与组成结构的复杂性和系统进化的要求 ,使得铁路智能运输系统必须具备开放的系统结构以实现异种系统、技术、规范、标准的包容 ;必须具备分布式智能问题求解能力以实现系统内部各子系统之间的协商协调处理 ,达到系统全局目标。
Two essential characteristics of Railway I nt elligent Transportation System (RITS) which are described as the open architectu re and the distributed intelligent system architecture have been discussed in th is article. Complexities of the environment and tasks of the railway transportat ion system are investigated at first. On the basis of these complexities, RITS n eeds to satisfy various objectives, so the open architecture of RITS is required to connect heterogenous systems, to contain different kinds of technology, crit eria and standards. At the same time the distributed intelligent system architec ture is required to implement negotiation/compromise between its subsystems to a ttain a global optimal objective. At the end of this article it is put forward t hat the open architecture and the distributed intelligent system architecture mu st be firstly investigated for RITS.
