摘　　要：从构件角度出发,结合软件agent技术,提出一种能表示根据需求和环境的变化实施自主行为的E-BDI构件模型。基于高阶多型π演算理论,在现有的动态体系结构描述语言D-ADL基础上,提出一种能从运行时角度描述自适应构件的动态行为的体系结构描述语言SOS-ADL。利用SOS-ADL形式化描述E-BDI结构的自适应构件行为,使构件能根据变化的环境和需求,自主推导自身的行为,达到实现软件自适应的目的。案例说明了面向自适应软件系统的体系结构描述语言SOS-ADL的应用。From component perspective, combined with the technology of agent, this paper presented an component model called E-BDI, which was able to adapt itself to the requirements’ and runtime environment’s variability. Based on the higher-order polytypic π-calculus theory, through the way of extended the existing researching achievement D-ADL, it presented an architecture description language SOS-ADL which could descript the self-adaptive component’s dynamic behavior from the runtime perspective. To reach the goal of self-adaptive software’s implement, depicied the self-adaptive component of E-BDI structure was formally with SOS-ADL, which could deduce itself behavior according to the variability of the environment and the requirement. At last, illustrated the software oriented self-adaptive architecture description language’s application through a case.
