摘要
在模糊框架下,提出了一种启发性的实物期权方法,根据梯形模糊数估计期望现金流和期望成本的现值,借助模糊数的数学期望值和方差,确定最佳执行时间,最后就该方法在欧洲某IT电讯公司投资战略中进行实证分析.
We introduce a heuristic real option rule in a fuzzy setting,where the present values of expected cash flows and trapezoidal fuzzy number estimates expected costs.Then we det ermine the optimal exercise time by the help of possibilistic mean value and variance of fuzzy numbers.In the end we analyze the method through the factual example about the investment strategic decisions in European IT enterprises.
