B Transportation Problem and Its Applications
B运输问题及其应用

In traditional transportation problem, the objective function is total transportation expenses. In special conditions, such as natural calamities occurred, the most important task is how to transport the goods and materials of emergency (including emergency squad and so on) from warehouses to each disaster area as quickly as possible. The later is a nonlinear multiobjective programming, and it is called B Transportation Problem. In this paper, the mathematical model of B Transportation problem is set up, and a solving method is given too.
