动态规划

The flexible manufacturing systems considered in the paper consist of possible unreliable workstations, whose inputs may be random. We derive the optimal input and service feedback control policy by using the uniformization technique and stochastic dynamic programming. It is shown that the optimal policy is of bang-bang type. Numeric example is given to illustrate the results.

对于具有随机输入和随机需求的一类不可靠柔性制造系统，利用转移率一致化技术和随机动态规划方法，给出了输入率和服务率分配的最优反馈控制策略，指出系统的最优控制具有bang-bang形式的开关结构，数值例子验证了文中的结果。

And to the problems of special distribution of underlying assets, this paper analyzes the price movement of the underlying assets from the arrival of information, the market efficiency and the market mechanism which decide the price. It also studies the problem of real option pricing when the underlying assets follow the pure jump Poisson, mixed jump-diffusion Merton and mean-reversion model, and obtains the price formula or partial differential equation to price and hedge the real option.
