摘要
利用线性规划单纯形表对线性规划原问题存在无穷多最优解和对偶问题存在无穷多最优解的情况进行了讨论，并分析了对偶问题存在无穷多最优解情况下的影子价格的方向性。最后以实例说明了各种情况。
In the paper,based on the simplex tableau alternative optimal solutions of the primal linear programming and the dual problem are discussed. Then the shadowprice is analyzed at the case of alternative optimal dual solutions. At last,some cases are applied. The paper may be helpful for the learner and decision maker in the field.
