Capacity Expansion of Network System

Yang Chao Zhu Yun College of Management, HUST, Wuhan 430074, China.  
A type of capacity expansion problem on networks is considered. A network N (V, E , ) is given and the capacity vector is increased so that the capacity of the maximum capacity tree can be increased to the maximum extent while the total cost for the increment of capacity is within a given budget limit, assuming that the cost of increment of capacity on each edge of network includes both fixed cost and increasing cost. A strong polynomial algorithm is proposed to solve the problem.
