为解决设备网格中资源动态变化造成的实验重现的困难,引入溯源服务。溯源服务以Web服务形式存在,记录设备网格内实验过程中诸如服务调用时间、服务请求者、服务提供者及用户评价等重要信息,形成溯源信息。为提高用户的满意程度,使用模糊变量来描述用户对其实验结果的评价,将溯源信息用于设备池的设备选择算法,增加令用户满意的服务质量好的仪器设备的使用率。实验结果表明:相对于随机调度算法,基于溯源信息的设备选择算法使得用户满意程度达80%。
In order to solve the difficulty of experiment recurring caused by the dynamic changes of resources in the equipment grid, traceability service was introduced. Traceability services exist in the form of Web services, and record important information such as service invocation time, service requesters, service providers and user evaluations during the experiment in the equipment grid to form traceability information. In order to improve the user’s satisfaction, fuzzy variables are used to describe the user’s evaluation of their experimental results. The traceability information is used in the device pool selection algorithm to increase the usage rate of the user equipment and equipment with satisfactory service quality. The experimental results show that, compared with the stochastic scheduling algorithm, the device selection algorithm based on traceability information makes user satisfaction up to 80%.
