摘　　要：在软件开发过程的早期引入性能需求,并通过建立性能模型对待实现系统的性能进行预测可以极大减小项目风险。给出了构件系统性能预测的一系列相关定义,总结并比较了各种性能模型在描述能力和解析难度上的优缺点。在总结通用的性能预测方法基础上,提出了基于模型的性能预测方法的一般思路。详细介绍了基于模型的构件系统性能预测3类方法,从多个方面对各种方法进行了比较和分析。探讨了当前研究中的不足之处,给出了本领域有前途的研究方向。Introducing performance requirement in early stages of software development process and predicting the performance of under-developed system by performance modeling can greatly reduce the project venture. A series of concepts in performance prediction （PP） of component-based software were brought up, and the diversity of performance models was compared in describing ability and analysis difficulty. Based on summing up common PP methods, the general course of model-based PP was extracted out. Three categories of approach on model-based PP of component-based software were introduced, and analyzed and compared from nine aspects subsequently. Some disadvantages of study on PP were discussed. Some significantly promising research directions were pointed out.
