上下层具有合作关系的两层决策问题研究

针对两层线性规划问题解的无效性，在决策者合作情形下，利用双准则线性规划的有关技术，提出事先不需求解问题而是采用次最优解作为参考点，直接在目标集中有效满意解的方法。数值计算结果表明该方法有效可行的。

Study on Bilevel Programming with Cooperation

As the solution of BLP problem may not be Pareto-optimal, if the decision makers of the two levels are willing to find an efficient compromise solution, the method which can generate efficient solutions by making use of techniques of bicriteria programming is proposed. When the near-optimal solution of the BLP problem is used as the reference point for finding the efficient solution, the result can be easily found during the decision process. The simulation results show it is efficient.
