Having its own prominent characteristics , spatial decision supporting technique can deal with many decision problems of semi - structurization and even non - structurization and treat with problems systemically and intelligentizedly and offer rewarding decision through automatic judgment , analysis , and induction of spatial massage , spatial relationship and spatial distribution law , making use of mature model and knowledge bases 空间决策支持技术有着自己显著的特点,能够处理很多半结构化甚至非结构化的决策问题。能够在通过对空间信息、空间关系、空间分布规律的自动分析、归纳和判断,利用成熟的模型库、知识库系统智能化地处理问题,给出有价值的决策结果。
In the system , dss integrates relative kb together , especially the train routing kb , approval experience kb . at the same time , the paper constructs the relative model of the claimed train approval optimization model in railroad bureau and uses the minimal cost and maximal flow algorithm based on queueing theory to solve the problem 在本系统中, dss中集成了相关的知识库系统,特别是车流径路知识库、审批经验知识库。同时,对铁路请求车审批优化中的请求车审批优化问题建立了相应的模型,并利用基于排队论的最小费用最大流求解了该问题。
The paper uses the romc method to analyse the claimed train approval optimization dss specifically . according to the peculiarity of the system , the paper uses the archetype method to design and develop the system , and design database subsystem , mb subsystem , kb subsystem in detail based on the giving the whole structure and the system structure 本文利用romc方法对铁路请求车审批辅助决策系统进行了详细的分析,基于本系统的特点,采用了原型法对系统进行了设计和开发,并在给出系统总体结构、系统体系结构的基础上,相应进行了数据库系统、模型库系统、知识库系统各个子系统的详细设计。
( 1 ) for methodological syncretization of emi and km , existing reference architectures ( ras ) do not clearly reflect the level characteristics of enterprise knowledge and its organization and application modes . ( 2 ) for enterprise knowledge capture and application , existing enterprise modeling methods face the dilemma of how to facilitate friendly collaboration and communication between system analysts / developers and enterprise staffs , and how to help system analysts / developers utilize model knowledge to carry out effective quantitative analysis . ( 3 ) for knowledge re - use , it lacks powerful knowledge repository systems for enterprise model re - use and corresponding mechanisms for knowledge extraction , classification and index 目前国内外关于该方向的研究尚处于起步阶段,有许多问题亟待解决,主要表现在:在企业集成与知识管理的方法论融合方面,现有参考体系结构没有很好地反映出企业知识的层次特征及其组织、应用方式;在企业知识的收集与应用方面,现有企业建模方法在如何促进系统分析设计人员与企业人员进行友好的合作与交流和如何帮助系统分析设计人员利用模型知识进行有效的定量分析这两个问题上存在着矛盾;在知识重用方面,缺乏面向企业模型重用的功能完备的知识库系统及相应的知识提炼和分类检索机制,能够被业界广泛接受的参考模型尚不多见;在建立面向企业集成的基于知识的系统方面,尚没有很好地解决知识的形式化表示问题,缺乏用于描述企业深层知识的形式化建模手段。
Visual c + + 6 . 0 is adopted in the software development of idss in asphaltum - concrete road construction . the software packed the database system , knowledge base system , model base system all together . the operation of addition , modification , deletion and insertion can be implemented easily , and the interface is friendly 采用visualc + + 6 . 0对沥青混凝土路面施工智能决策调度支持系统进行了软件开发,该软件把数据库系统、知识库系统、模型库系统封装在一起,可以很方便地完成对各个库的操作(添加、修改、删除、插入)等,界面友好直观,易于操作,便于理解。
