We study a two-period duopoly game with capacity accumulation under demand uncertainty, production and time-to-build constraints. These considerations are relevant in network industries such as electricity markets and hot spot markets.We characterize and compare open-loop, Markov perfect and closed-loop Nash equilibrium investments.

.hot metal gas forming of tubes can be used in various industries such as automotive and aerospace industries. in this process tube is formed at elevated temperatures, by using gas instead of fluid pressure. lower required pressure and low power are its advantages in comparison to hydroforming process. in this paper, a hot metal gas bulging process of an aluminum alloy tube has been investigate...
