CODP position of leagile supply chain based on polychromatic sets theory

To the positions of customer order decoupling point on leagile supply chain, according to the resource capacity of supply chain members, a kind of decision making model represented by CODP on supply chain are established. The decision making model was formally described in mathematical language to make it readily manipulated by computers through using the polychromatic sets. Then, using the reasoning matrix between the unit color and individual color of the polychromatic sets, the reasoning of decoupling points positioning was obtained. Finally, a case studies including two manufacturers enterprise on supply chain network is used to illustrate the proposed model and approach.
