Abstract

User experience and satisfaction of web services and service chain are majorly determined by the quality of services (QoS), which is critical to services selection. Geo-data services and processing services are two fundamental services types of geo-services, where geo-data services provide geo-data, and processing services process and produce data. Therefore, the data quality of geo-data provided by geo-data services and the capabilities of geo-data processing to processing services are inherent characteristics and key quality factors of those geoservices. In this paper, the output quality factors are introduced to cope with above-mentioned characteristics of geo-services. Coupling with process quality factors (common measurement quality factors of web services), a preliminary QoS assessment model for geo-services is proposed. The dynamic feature and the aggregation functions of QoS factors are discussed. Finally, a services instances' optimization selection algorithm based on linear programming is designed.
地理空间服务链QoS评估与优化研究
用户对web服务和服务链的体验和满意度主要取决于服务质量(QoS),服务质量对服务选择至关重要。地理数据服务和处理服务是地理服务的两种基本服务类型,其中地理数据服务提供地理数据,处理服务处理和产生数据。因此,地理数据服务提供的地理数据质量和地理数据处理服务的能力是地理数据服务的内在特征和关键质量因素。本文针对地理服务的上述特点,引入了输出质量因子。结合过程质量因子(web服务常用的度量质量因子),提出了一个初步的地理服务质量评价模型。讨论了QoS因子的动态特性和聚合函数。最后,设计了一种基于线性规划的服务实例优化选择算法。
