Health evaluation of liquid hydrogen providing system based on fuzzy data fusion method 基于模糊数据融合的液氢供应系统健康评价方法
In the fuzzy database, it is different from traditional database in expression and updating the fuzzy data because of the fuzzy property 摘要由于模糊数据所具有的模糊属性,使得在主动模糊数据库中模糊数据的表示以及对模糊数据的更新处理均不同于传统数据库。
Abstract : reviews the methods of defrosting control of air source heat pumps, puts forward the idea of self-tuning fuzzy defrosting control, and presents the fundamental construction, the method for determining the input domain and converting input parameters to fuzzy data 文摘:回顾了空气热源热泵除霜控制方法,提出了自调整模糊除霜控制的思想,介绍了系统的基本结构,输入论域的确定,输入量的模糊化和模糊推理方法。
Basing on the three levels ’ data processing, a new way to manage the fuzzy data is put forward . in this mentioned way, which can be used for reference in future linguistic application in data warehouse, a query column is added to realize the function of fuzzy olap and fuzzy query 在完成三层数据加工的基础上,论文提出在数据仓库内部通过建立和完善模糊数据元数据实现对品质层和程度层模糊数据的管理,通过定义查询值列实现模糊olap和模糊查询应用,为今后语义技术在数据仓库中的应用提供了借鉴。
The paper, in order to support for alteration of enterprise data analysis requirements, provides a kind of adaptive online analysis processing and data mining model ( abbreviated dolam ), its logic structure, system frame and physical structure are presented, which enhances hominine direction and controlling mechanism, embodying in such aspects as query-driven, fuzzy data mining and dynamic interactive ability etc . the paper offers design and implementation blue print of the core of dolam-- data warehouse management tool, olap tool and summarysql tool, now, they are running in dalian international cooperation ( group ) stock ltd and have gained good effect 四、决策敏捷依赖于dss的柔性,为增强dss的柔性,本文提出一种具有可适应的联机分析挖掘模型dolam,设计了它的逻辑结构、体系结构和物理实现结构。该模型加强了人的导向和控制机制,体现在查询驱动、模糊挖掘、动态交互方面。本文给出了dolam的核心部分?数据仓库管理工具、olap工具、summarysql模糊查询挖掘工具的具体设计和实现方案,并运用它于大连国际合作(集团)股份有限公司的决策支持实践中,取得了较好的应用效果。
