A Gray Programming Model for Bi-Level Distribution Network Designing in the Supply Chain

In this paper, a gray programming model for bi-level distribution network design in the supply chain is presented by means of uncertain-system theory, in which both customers' demands for products and production capacity of branch plants are treated as gray parameters. Combine concrete example, that the reasonableness and in accord with scientific principles for make use of gray parameters are discussed. Finally, a comment on "Randomized programming model" is also given. Supply chain is a kind of enterprise network which is combined with fluxion and transformation of material, How to establish effective supply chain and exert its function farthest is the emphasis of contemporary enterprise management. On account that supply chain always represents "Demand chain" which is derived by market and client demand.
