【摘要】:中文摘要:本文從實際社會人口學(xué)的研究問題出發(fā),提出了一類特殊的人口預(yù)測問題,即預(yù)測未來人口可能達(dá)到的最大值與最小值.這類問題可以被描述成帶約束條件的最優(yōu)控制問題.本文首先證明了最優(yōu)控制的存在性,然后構(gòu)造出了最優(yōu)對的形式,并證明了它確實是原問題的最優(yōu)解.在此基礎(chǔ)上,本文又提出了一個終端狀態(tài)固定的新問題,并得到了類似的結(jié)論.最后,利用動態(tài)規(guī)劃的方法重新分析了這一帶狀態(tài)約束的最優(yōu)控制問題,給出了值函數(shù)并討論了值函數(shù)的性質(zhì)以及它所滿足的HJB方程.
[Abstract]:Abstract: this paper presents a special population forecasting problem based on the study of actual social demography, that is, the maximum and minimum values that the population may reach in the future. This kind of problem can be described as an optimal control problem with constraints. In this paper, we first prove the existence of optimal control, then construct the form of optimal pair, and prove that it is the optimal solution of the original problem. On this basis, a new problem of terminal state fixation is proposed and a similar conclusion is obtained. Finally, the optimal control problem with state constraints is reanalyzed by using the dynamic programming method. The value function is given and the properties of the value function and the HJB equation which it satisfies are discussed.
