摘　　要：针对具有模糊持续时间的产品开发项目工期—成本均衡调度问题,进一步考虑了模糊环境下决策者风险偏好(可接受风险水平与乐观指数)对工期—成本均衡的影响,并运用NSGA-Ⅱ算法,结合项目实例,对该问题进行了求解和分析。研究表明,通过调整决策者的可接受风险水平或乐观指数,可以获得一系列不同的Pareto解,以便决策者从中选择其偏好的调度方案。Aiming at the time and cost tradeoff problem in product development project scheduling with fuzzy durations,this paper considered the effect of decision-makers＇ risk preference on time and cost tradeoff in fuzzy environment further,and it introduced NSGA-Ⅱ to solve the problem in project example.The results show that by means of adjusting the values of risk acceptance level and optimism index,different Pareto sets are obtained,from which the decision can choose the preferred scheduling alternative.
