| 摘 要： | 对象管理组织(OMG)提出的软件过程工程元模型(SPEM)在软件工程过程领域具有较强的通用性和较好的建模能力。但是，软件过程工程元模型在一致性和表达力上存在不足。本文基于UML2．0活动元模型改进SPEM中活动的语义，采用泛化机制扩大实参的表达范围，细化形参和限制的表达粒度，使得改进的软件过程工程元模型(ISPEM)在语义上与软件工程过程领域的语义更为一致，表达力更强，更加符合软件工程过程领域建模的需要。

| Abstract: | Software process engineering metamodel (SPEM) made by object management group (OMG) has better compatibility and powerful model capability in software engineering process domain. However, SPEM has less consistence and weak expressiveness. The semantic of SPEM was improved based on UML 2.0 acting metamodel, the argument's expressiveness scale was extended using generalization mechanism, and the expressiveness granularity of parameter's and constraint's was refined. The semantics of improved SPEM (ISPEM) are more close to software engineering process domain, and make ISPEM more expressiveness power and more suitable for modeling software process engineering domain. |
