Abstract:

In order to achieve easier application of the factor space theory easily based on its impact on the object set of multidomain value attributes,we propose a graphical representation for an object with the domain value attributes, namely attribute circle, using cluster analysis.The circle can represent the impact of infinite multidomain attributes on the object.We first analyze the similarities of the objects based on the attribute circle concept.For the convenience of calculation,graphical definition is converted to numerical similarity definition, and the clustering analysis method of object set is studied.The clustering principles are: strictly complying with similar division or dissimilar division,and referencing to the fuzzy similarity division.We take the system reliability of an electrical system as the research object set,and analyze the cluster of the expression group.The corresponding relationship between the decision set D and the object set U show that the division of the object sets is singular and accurate in terms of decision attributes.Although the system reliability is evaluated in different circumstances,these evaluation semantics are relatively objective and they can support each other.
