云制造环境下板材余料资源的服务匹配方法

Service matching method for surplus sheet material resource in cloud manufacturing environment

在云制造环境下,针对中小型企业加工后的板材余料造成极大资源浪费的问题,提出了一种基于语义相似度算法同时融入QoS(quality of service,服务质量)信息的分层次资源描述模型。首先,建立板材余料和板材加工设备资源的本体模型;然后,基于语义相似度算法对板材余料和板材加工设备的各个属性参数进行匹配,得到初选服务集合;最后,通过模糊QoS匹配算法将描述用户需求的自然语言转化成三角模糊数,得到服务设备的优选集合。实例仿真结果表明,所提出的方法将板材余料作为制造资源接入云制造平台,以服务的形式进行共享,增强了服务匹配过程的准确性和可靠性,实现了对板材余料和闲置的板材加工设备资源的合理调度和使用。研究结果可为云制造环境下余料和加工设备资源的匹配优选提供一种新思路。

In the cloud manufacturing environment,aiming at the problem of huge waste of resources caused by the surplus sheet materials after processing by small and medium-sized enterprises,a hierarchical resource description model based on the semantic similarity algorithm and integrating the QoS(quality of service)information is proposed.Firstly,the ontology models of surplus sheet material and sheet processing equipment resources were established;then,based on the semantic similarity algorithm,the attribute parameters of surplus sheet material and sheet processing equipment were matched to obtain the primary selection service set;finally,the natural language describing the user’s requirements was transformed into triangular fuzzy numbers through the fuzzy QoS matching algorithm,and the optimal set of service equipment was obtained.The simulation results showed that the proposed method took the surplus sheet materials as manufacturing resources to access the cloud manufacturing platform,and shared them in the form of services,which enhanced the accuracy and reliability of the service matching process and realized the reasonable scheduling and use of surplus sheet material and idle sheet processing equipment resources.The research results can provide a new idea for the matching and optimization of surplus sheet material and processing equipment resources in the cloud manufacturing environment.
