基于ATLAS转换语言的模型转换初探

提出一种利用ATLAS转换语言接收转换信号的模型转换框架,当平台无关模型(Platform Independent Model,PIM)向平台相关模型(PlatformSpecialize Model,PSM)转换时,利用ATLAS转换语言对发出的信号进行模型转换判断,属于模型转换信号则执行信号任务,否则进行可行性判断,若为可行信号,则返回入口处等待接收新信号,若为不可行信号,则向数据库报告并将不可行信号写入日志。

Model transformation based on ATLAS transformation language

As mining investment is a kind of venture capital,there are a lot of uncertainty and ambiguity in the process of evaluating on mining investment decision.With the data mining technology,the relationship of object classification and index membership is affirmed based on the entropy to mine knowledge information about object classification hidden in every index.The redundant data in index membership for object classification is eliminated by defining distinguishable weight and extracting valid values to compute object membership.The new algorithm of membership degree transformation consists of three calculation steps which could be summarized as "effective,comparison and composition",and denoted into M(1,2,3).The new algorithm is applied in fuzzy evaluation on mining investment decision,and the case study indicates that this method is characterized by practicability and high confidence for application.
