Explorations on the solution to membrance stress of full liquid vessel;

With market rules,bidding strategies and investment strategies of market participants being represented as experimental environment,this paper studies long term dynamics of generation capacity adequacy by using dynamic simulations of investment market interacted with power market.

The network capacity is defined as the value of the maximum s-t flow, and a unified model is introduced for the network capacity expansion with the time and cost constraints.

Four special capacity expansion problem of undirected network were discussed and the responsible strongly polynomial algorithm was get.

It is generalized that one type of constrained maximum cpapcity expansion path problem on networks to a type of constrained capacity expansion problem with setup cost on undirected networks,and a strongly polynomial algorithm is get.
