Abstract: The thought of schemes combination (SC) of cotton assorting was discussed.A set of mathematic model for schemes combination was established.The model considered requests of spreading bales on plucker while confirms proportion of each selected raw material.As the model included some indeterminate factors,enumerative algorithm in detail to solve the model namely to make sure of proportion of each selected raw material was studied.The result indicates:the schemes are more complete,one of that is a global optimization after estimating,but the enumeration quantity is numerous.
