融资投资决策的动态随机优化模型及其应用的研究

On Research of a Dynamical Optimal Model of Financing and Investing Decisions(DROMFID)and Applications

本文以目前我国一些融资投资性公司的实际情况为背景,提炼并建立了融资投资决策的动态随机优化模型.该模型比较成功地解决了在考虑到利率和汇率风险情况下投资项目和规模的选择,信贷的方式、外汇币种和规模的选择,投资和信贷的最佳时机以及风险的回避和资金预算平衡等一系列问题.在把模型转换为一个二次规划问题之后,文中给出了模型的求解方法.最后介绍了模型的实际应用情况。

Taking financing and investment companies of China as background,this paper sets up a DROMFID.The model successfully solves the problems suchas optimal projects and sides of investment;optimal methods,currency structureand sides of financing(borrowing and lending);optimal time of investing andfinancing;avoidance of risk;budget balance of capital when risk of interest ratesand exchange rates are considered.After the DROMFID is converted into a qua-dratic programming problem,the authors puts forward the methods of solving theDROMFID.The applications of the DROMFID are discussed at the last part ofthe paper.
