中文摘要：

软件阶段努力评价能被用来动态地调整软件工程安排，推进帮助使工程在预算内完成了。这篇论文论述灰模型 Verhulst 在软件开发过程期间为阶段努力评价基于方法，一种偏爱修正技术被用来改进评价精确性。建议方法与一个大规模工业软件工程数据库被评估。结果是很令人鼓舞的；显示方法有可观的潜力。

英文摘要：

The software stage-effort estimation can be used to dynamically adjust software project schedule, further to help make the project finished on budget. This paper presents a grey model Verhulst based method for stage-effort estimation during software development process, a bias correction technology was used to improve the estimation accuracy. The proposed method was evaluated with a large-scale industrial software engineering database. The results are very encouraging and indicate the method has considerable potential.
