In 2001 , professor zhang defined the inclusion variations , disjoint variations and chain variations of set functions , and then discussed the properties of the three kinds of variations . he found that variations play an important role in the decompositions of signed fuzzy measures and signed lower semicontinuous fuzzy measures , just as they do for signed measures , additive fuzzy measures , non - monotonic fuzzy measures and t - measures
2001年，在论文《 somepropertiesofthevariationsofnon - additivesetfunctions 》和《 somepropertiesofthevariationsofnon - additivesetfunctions 》中，张强教授提出了集函数的内含变差，不交变差和链变差的概念，并详细讨论了这三种变差的性质。
