Haiyan Luo, Linzhong Liu, Xun Yang are researchers who have worked on the bi-level programming problem in the supply chain and its solutions. The bi-level programming problem is a mathematical optimization problem that involves two levels of decision-making: the upper level and the lower level.

In the context of the supply chain, the upper level represents the decisions made by the supply chain manager or the leader, while the lower level represents the decisions made by individual agents or participants in the supply chain, such as suppliers, manufacturers, or retailers.

The goal of solving the bi-level programming problem in the supply chain is to find an optimal solution that maximizes the overall performance of the supply chain while considering the conflicting objectives and constraints at both levels. This problem is challenging because the decisions made at one level affect the decisions and outcomes at the other level.

Haiyan Luo, Linzhong Liu, Xun Yang, and other researchers have proposed various approaches and algorithms to solve the bi-level programming problem in the supply chain. These solutions often involve mathematical modeling, optimization techniques, game theory, and simulation methods.
