【摘要】 本文对运输问题的产销量系数ai及bi进行灵敏度分析。给出了在保持已求得的最优基不变的条件下,系数ai及bi可同时变动的范围;并讨论了当两系数的变动超出了其灵敏度范围时,如何简便地求出新的最优解。更多还原

【Abstract】 In this paper,sensitivity analysis is performed on supply and demand constraints(a_i and b_j)of a transportation problem.It is shown how to determine an interval for them to alter simultaneously such that current optimal basis remains unchanged,and also discussed how to find a new optimal solution when a change in a_i and b_j exceeds the interval.更多还原
