Component model of product application service based on generalized dynamic constraints satisfaction

为提高产品应用服务系统的构建效率和服务设计的复用性能,提出可配置的产品应用服务构件模型及其配置实现机制。首先,给出了产品应用服务服务要素及其相互关系的描述,针对应用服务构成要素的特点,提出可配置的产品应用服务构件模型;然后,根据产品应用服务构件模型中的特征变量、接口变量、属性变量和约束关系的特点,提出了产品应用服务构件模型的广义动态约束满足转换的概念,通过变量集和约束集对构件模型进行描述,并采用双层组合启发式求解算法实现构件性能的综合最优化,生成一簇具有较高复用价值和复用性能的产品应用服务构件。最后通过实例,验证了所提模型的实用性和有效性。

To improve construction efficiency and reuse performance of product application service system, a configurable product service component model and its configuration realization scheme were put forward. Product application service component and the basic elements of the model were firstly defined. Based on the analysis of variable features, such as characteristics variables, interface variables, attribute variables and constraint relationships, the modeling process of the component was transformed into generalized dynamic constraint satisfaction by configuring the basic elements of the service, which uniformly applied the sets of variable and constraint to express component model. A solution called two-layer combinatorial heuristic algorithm was used realize overall optimization. And a set of service components with high reuse value and good reuse performance was generated. Finally, a case of mainte- nance management was given to verify the practicability and effectiveness of this model.
