Abstract: In this paper,general research situation for information processing implementation of discrete event dynamic system theory is introduced,Simple development history of polychromatic sets which as new information processing implementation is narrated.Compared with net Petri,in side of problematic formalization expression this information processing implementation has gone ahead,it has distinctly predominance.Its simulation function is more powerful.Above is its contribution in theory.Based on the base saying about concept and standard mathematical model of polychromatic sets,the relations between unification color and individual color are narrated.Finally a case is cited.
