To make it clear , the article use and analyze numerical value cases from bellmum and zadeh . finally in order to work out the value function in all forms and the expected value of optimization in all aspects easily , we take down all the problem existing in multi - stage stochastic decision processes . the solution of optimum is formed and multi - stage stochastic decision tree - table is introduced 為說(shuō)明問(wèn)題,本文利用bellman和zadeh [ 1 ]的數(shù)值例,應(yīng)用兩種方法進(jìn)行分析,最后為了更方便的解出對(duì)所有形式的評(píng)價(jià)函數(shù),及其期望值的最優(yōu)化解對(duì)各種進(jìn)行的發(fā)展,把經(jīng)過(guò)多階段概率決策過(guò)程的問(wèn)題記述下來(lái),構(gòu)成一個(gè)最優(yōu)解的統(tǒng)一圖表,引入了多段概率決策樹(shù)表。
