Abstract
An algorithm for attribute extraction is proposed to meet the objective demand of produc-tion scheduling rule discovery for data set attribute reduction.Firstly,the characteristics of the pro-duction data are analyzed,and the attributes of production data are divided into several sets according to their importance and correlation.Then,the importance objective function is established to find the important attributes by using the fuzzy entropy and the clustering accuracy.Finally,the correlation analysis is used to find the related attributes of the important attribute,which are then merged to form the important composite attribute to enhance the effect of attribute extraction.In order to verify the validity of the technology,a subset obtained by the technique is compared with another subset ob-tained by the stochastic method,and the compatibility and the accuracy of rule extraction between them are analyzed.The experimental results show that the data subset formed by attribute extraction has lower incompatibility and can concentrate the scheduling rule knowledge of the original data sets, which mean that the accuracy and efficiency of a variety of scheduling rule discovery algorithms can be improved significantly.Thus,the technology developed is suitable for the attribute extraction in the preprocessing stage of the production scheduling rule discovery.关键词
