【摘要】 目前全路大多数主要编组站已实现“编组站货车管理信息系统”（ＹＩＳ），但由于投产年代不同，设备类型、系统软件、开发形式各有差异，为使今后发展规范化，对小型机方案和全微机方案，从一次性投资、数据共享、可靠性、信息处理能力等方面进行比较，认为编组站适宜采用小型机方案。并根据ＹＩＳ存在的问题，提出今后发展的重点和方向更多还原

【Abstract】 At present,most of the major marshalling yards in China have applied the Marshalling Yard Freight Car Management Information System(YIS).However,because of different period of being put into use,there are differences in equipment type,system software and development form.In order to standardize future development,the author made comparison between small sized computer and all microcomputer plans from the aspects of one time investment,data share,reliability and information processing ability,and thought that the small sized computer plan is applicable to marshalling yards.According to the existing problems of YIS,the author also put forward the focus and direction of future development.更多还原
