Element-filling System Subdivision Method

Even though the system subdivision of MIS has been widely researched and practiced.It has not been solved satisfactorily.The methods used mainly in the past include U/C matrix in BSP and cluster analysis with fuzzy theory,there exist many experiential factors in the appraisable criteria.In view of the above facts,this paper proposes a element filling system subdivision method,which selects an optimal one from all possible solutions by an appraisal criterium of coupling ratio of intrasubsystem to intersubsystem.The new method has been applied to a MIS project with perfect result.
