Abstract:
For the service reuse problem in pervasive computing, an optimal quality-oriented approach is proposed. The approach achieves service functionality match based on an inverted index, evaluates service quality with the multiple attribute decision making theory, and employs branch and bound algorithm for optimal composition plan generation. Experimental results demonstrate the effectiveness of the proposed approach in improving the quality of generated services.

摘要: 针对普适计算模式下的服务复用及服务质量问题,提出一种面向最优质量的服务复用方法。通过建立服务功能倒排索引完成已有服务的功能匹配,采用多属性决策理论进行服务质量的量化和评价,并利用分枝定界法搜索最优质量的服务组合,生成满足用户需求的服务。实验结果验证了该方法在提高生成服务质量方面的有效性。
