<P align=left><FONT face=宋体 size=3><STRONG>Abstract </STRONG>This paper is
the sixth of a series of papers of discussing in detail factor spaces and
knowledge representation based on factor spaces.The properties and
generation and applications in fuzzy decision-making of
ASM<SUB>m</SUB>-func are introduced.Then general models of multifactorial
decision-making is given and an example is discussed for showing how to
use the models.<BR><STRONG>Key words:</STRONG>factor spaces,knowledge
