造林项目预期现金流量的影响因素较多,经营过程中需综合考虑以达到最优配置。通过确定速生造林项目现金流量种类,分析其影响因素、发生过程及变化规律,以对各种现金流量建模,并利用计算机软件建立仿真模型。为获得最优净现值,对有决策意义的影响因素进行优化求解,并通过人工测试或系统重复运行找到最优方案。
造林項目預期現金流量的影響因素較多,經營過程中需綜閤攷慮以達到最優配置。通過確定速生造林項目現金流量種類,分析其影響因素、髮生過程及變化規律,以對各種現金流量建模,併利用計算機軟件建立倣真模型。為穫得最優淨現值,對有決策意義的影響因素進行優化求解,併通過人工測試或繫統重複運行找到最優方案。

There are many factors that influence cash flows must be considered interactively to achieve optimal configurati expected in a on. Cash flow forestation project. They species of the project are defined and their influence factors, generating processes and change rules are forestation found and modeled. Then, a computer simulation model is established in Extensim. To obtain the optimal re- sult, decision factors is optimized by artificial tests or automatic repeated runs to find the optimal solu- tion.
