对众多需要实施项目进行优化选择,找出合理的优先级标准的方法,是进行多项目管理研究中需要解决的关键问题.针对有限资源限制和众多项目需要实施的决策管理,作者研究依据项目间资源转移矩阵找出优先级标准,从项目设计和已实施的项目中提取项目间资源转移关系,通过量化处理后构造资源转移概率矩阵,则与该资源变化矩阵对应的马尔科夫链的平稳分布即为项目最终占用资源的比例序列或项目的影响程度序列;以此作为评价项目优先级的标准,确定项目重要程度的排序.
對衆多需要實施項目進行優化選擇,找齣閤理的優先級標準的方法,是進行多項目管理研究中需要解決的關鍵問題.針對有限資源限製和衆多項目需要實施的決策管理,作者研究依據項目間資源轉移矩陣找齣優先級標準,從項目設計和已實施的項目中提取項目間資源轉移關繫,通過量化處理後構造資源轉移概率矩陣,則與該資源變化矩陣對應的馬爾科伕鏈的平穩分佈即為項目最終佔用資源的比例序列或項目的影響程度序列;以此作為評價項目優先級的標準,確定項目重要程度的排序.

During the multi-project management research, finding out a reasonable priority standard to perform the optimization section of multi-project is the key issue that needs to be carried out. For the decision management of limited resources and numerous projects, the author provides the priority standard according to the transition matrix of resources among projects. And extract the transition relations of resources from the projects designed and implemented, then structure transition probability matrix of resources through quantifying the transition relations of resources among projects, the stationary distribution of the Markov chain which is corresponding to the resource matrix, is the ration sequence of final resources occupation or the influence level sequence; the authors take it as the criteria of evaluating the priority of projects and determining the ranking of significance.
