云制造作为一种新型的面向服务的制造模式，是针对制造企业的不足而提出的。随着信息技术和其他高新技术的飞速发展，CMfg很好地满足了现代制造业的发展要求，得到了一定的普及。资源和任务的管理、共享和调度是CMfg系统的关键特性之一，它直接影响到CMfg服务平台的准确性和效率。为了实现资源和任务的有效管理、方便使用和可靠事务，建立了CMfg服务平台信任评估体系框架，提出了面向机械制造领域的CMfg服务平台信任评估模型。在该体系中，通过层次分析法（AHP）确定了六个信任评价指标的权重。同时，采用离散化方法设计了直接信任服务的量化和更新算法。通过云理论模型和云焦点评价方法提取推荐信任服务。基于虚拟交易数据的实验验证了该信任评估模型的有效性和效率。
Aiming at the shortcomings of manufacturing enterprises, cloud manufacturing (CMfg), as a new type of service-oriented manufacturing mode, is put forward recently. Due to the rapid development of information and other high-tech technologies, CMfg excellently satisfies the development requirements of modern manufacturing and gains some popularity. As one of the key characteristic for CMfg system, the management, sharing, and scheduling of resources and tasks will directly affect the accuracy and efficiency of CMfg service platform. In order to achieve the effective management, convenient use, and reliable transactions of resources and tasks, a framework of trust evaluation system in CMfg is established and a trust evaluation model of CMfg service platform oriented to mechanical manufacturing field is proposed. In this system, the weights of six trust evaluation indexes are obtained through analytic hierarchy process (AHP) method. Meanwhile, the quantitative and update algorithm for direct trust service is designed through a discrete method. Furthermore, the recommendation trust service is extracted through cloud theory model and cloud focus evaluation method. Experiments based on virtual transaction data are conducted to verify the validity and efficiency of the proposed trust evaluation model.
