NEW Technique Development on PlugFlow Dense Phase Transportation of Aluminum Oxide
The application of principal,characteristics,and developing results of pugflow industrial densephase transportation of aluminum oxide in commercial production of aluminum electrolysis are described.In the single unit equipment applying this technology,the capacity of transportation of aluminum oxide is more than 35 t/h;power index is only0.0102 kW.h/ton material.It proves that the developing result has a prospect to be utilized and popularized in industry.
In this paper, we study the asymptotical optimal solutions for the general airline revenue management problem, considering both customer cancelations and no-shows. We study a simple case where there is only one fare-class; the management controls the opening and closing of the fare-class, with the objective of maximizing the total revenue. We first develop a fluid control problem, where the customer arrival and cancelation processes are treated as deterministic, whereas the no. of no-shows is random. The optimal fluid solution is shown to have a simple structure of accepting up to a single time point t* and rejecting afterwards. We show that this policy acts as an upper bound for the MDP problem. Applying the optimal fluid solution to the stochastic environment, we show that this policy is asymptotically optimal on the fluid scaling.
