動(dòng)態(tài)規(guī)劃法是決策分析中的一種常用方法,是解決多階段決策過(guò)程問(wèn)題的一種最優(yōu)化方法。所謂多階段決策過(guò)程,就是將問(wèn)題分成若干個(gè)相互聯(lián)系的階段,每個(gè)階段都作出決策,從而使整個(gè)過(guò)程達(dá)到最優(yōu)化。許多實(shí)際問(wèn)題利用動(dòng)態(tài)規(guī)劃法處理,常比線性規(guī)劃法更為有效,特別是對(duì)于那些離散型問(wèn)題。
設(shè)計(jì)一個(gè)標(biāo)準(zhǔn)的動(dòng)態(tài)規(guī)劃算法,通常可按劃分階段和選擇狀態(tài)兩個(gè)步驟進(jìn)行。
