3、是判定出系统当前处于什么状态。第3,对各系统未来发展的每次转移概率进行预测,就是要确定出系统是如何转移的。最后,根据系统当前的各种状态和转移概率矩阵,推测出系统经过若干次转移后,到达各个状态的概率。本文简述了马尔可夫链的基本原理,基于经济活动的复杂,多变性及带有许多随机因素的特点,利用了马氏过程的基本特征,巧妙的构造转移概率矩阵,建立起马尔可夫预测模型,对商品市场经济的发展和公司的期望利润作出了预测。关键词:马尔可夫链; 转移概率矩阵; 市场占有率; 期望利润AbstractThe Markov chain carried on the forecast using the mathemati

4、cal model to the qualitative question to provide one kind of mentality, has enriched the forecast content. Carries on the forecast using the Markov chain the basic mentality is: First, regards as the phenomenon is one kind of system, and carries on the science to this system the condition division.

5、The content and needs to divide many conditions which according to the system reality, the system divides each condition which is needs to forecast. Next, carries on the statistical determination to the phenomenon each condition probability of state, also is determines the system currently to be at

6、any condition. Third, each time transition probability which future develops to various systems carries on the forecast, is must determine how the system is shifts. Finally, according to the system current each condition and the transition probability matrix, after extrapolated the system passes thr

7、ough certain shifts, arrives each condition the probability. This article has summarized the Markov chain basic principle, based on economic activity complex, the polytropy and has many random factors characteristics, has used the Markov process basic characteristic, The ingenious structure transition probability matrix, establishes the Markov forecast model, has made the forecast to the commodity market economy development and companys expectation profit.Keywords:Markov chain; Transition probability matrix; Market share; expectation profit
