摘　　要：为改善目前云制造服务供需平台匹配交易过程中存在的信用问题,针对云制造服务供需匹配交易流程提出了一种在Hyperledger Fabric联盟链架构下基于节点被证书颁发机构(certificate authority, CA)授予身份证书的信用激励机制,该激励机制以企业利益作为用户节点行为的约束条件,以提高交易过程中各方参与者信用为导向,综合运用声誉激励和权利激励来促进区块链网络中的各节点提高履约概率.文中运用Anylogic仿真软件对此信用激励机制构建智能体模型并进行仿真实验.实验结果表明,构建的信用激励机制能够有效提高用户节点在执行合约时的履约意愿,为保障用户在云制造服务供需平台中实现可信交易提供了理论依据.In order to improve the credit problems existing in the matching and transaction process of cloud manufacturing service supply and demand platform,a credit incentive mechanism based on the identity certificate granted by the certificate authority under the Hyperledger Fabric alliance chain architecture is proposed for the cloud manufacturing service supply and demand matching transaction process.The incentive mechanism takes the enterprise benefit as the constraint condition of the user node behavior,and is oriented to improve the credit of all participants in the transaction process.Reputation incentive and right incentive are used to improve the performance probability of each node in the blockchain network.In this paper,the agent model of this credit incentive mechanism is built by using Anylogic simulation software,and the simulation experiment is carried out.The experimental results show that the credit incentive mechanism can effectively improve the user node′s willingness to perform the contract when executing the contract,which provides a theoretical basis for ensuring users to achieve trusted transactions in the cloud manufacturing service supply and demand platform.
