The decision-making model of partnership portfolio on supply chain

In order to construct the members of the supply chain, make the same status in the superior position of priority degree, this paper use fuzzy syntheses to evaluate the members of Supply Chain; then, based on polychromatic sets theory, can descript the collaboration partnerships strength of supply chain network formally, and avoiding the pseudo fuzzy evaluation of optimal solutions; the supply chain by building cooperation between the members of the combination mathematical model to determine the genetic algorithm fitness function, to improve supply chain network construction global stability; Finally, using this improved genetic algorithm on whole supply chain network optimization.
