A Solution to Interval Linear Bi-level Programming and Its Application in Decentralized Supply Chain Planning
Decentralized supply chain planning problems naturally combine multiple decision steps,which are connected in a hierarchical way.Different participants usually have incomplete information for various reasons,such as ego-defense.In this paper,the linear bi-level programming with interval coefficients in lower level objective function is formulated as an extension of the classical linear bi-level problem under an inexact environment.The best solution,best value and best coefficients are defined,respectively.Moreover,a method based on Kth-best algorithm is employed to solve the problem; the coefficients impact on solution is analyzed,and a numerical example is presented to illustrate effectiveness of the present method.Finally,advantages of the method in decentralized supply chain planning are discussed.
