Recently, manufacturing firms and logistics service providers have been encouraged to deploy the most recent features of Information Technology (IT) to prevail in the competitive circumstances of manufacturing industries. Industry 4.0 and Cloud manufacturing (CMfg), accompanied by a service-oriented architecture model, have been regarded as renowned approaches to enable and facilitate the transition of conventional manufacturing business models into more efficient and productive ones. Furthermore, there is an aptness among the manufacturing and logistics businesses as service providers to synergize and cut down the investment and operational costs via sharing logistics fleet and production facilities in the form of outsourcing and consequently increase their profitability. Therefore, due to the Everything as a Service (XaaS) paradigm, efficient service composition is known to be a remarkable issue in the cloud manufacturing paradigm. This issue is challenging due to the service composition problem's large size and complicated computational characteristics. This paper has focused on the considerable number of continually received service requests, which must be prioritized and handled in the minimum possible time while fulfilling the Quality of Service (QoS) parameters. Considering the NP-hard nature and dynamicity of the allocation problem in the Cloud composition problem, heuristic and metaheuristic solving approaches are strongly preferred to obtain optimal or nearly optimal solutions. This study has presented an innovative, time-efficient approach for mutual manufacturing and logistical service composition with the QoS considerations. The method presented in this paper is highly competent in solving large-scale service composition problems time-efficiently while satisfying the optimality gap. A sample dataset has been synthesized to evaluate the outcomes of the developed model compared to earlier research studies. The results show the proposed algorithm can be applied to fulfill the dynamic behavior of manufacturing and logistics service composition due to its efficiency in solving time. The paper has embedded the relation of task and logistic services for cloud service composition in solving algorithm and enhanced the efficiency of resulted matched services. Moreover, considering the possibility of arrival of new services and demands into cloud, the proposed algorithm adapts the service composition algorithm.
最近,制造企业和物流服务提供商受到鼓励,采用信息技术(IT)的最新功能,以在制造业的竞争环境中占据优势。工业4.0和云制造(CMfg),伴随着面向服务的架构模型,被视为使传统制造商业模式向更高效、更具生产力的模式转变的著名方法。此外,制造和物流企业作为服务提供商,有能力通过以外包形式共享物流车队和生产设施来协同合作,降低投资和运营成本,从而提高盈利能力。因此,由于一切皆服务(XaaS)范式,高效的服务组合在云制造范式中是一个显著问题。由于服务组合问题规模庞大且计算特性复杂,这个问题具有挑战性。本文关注大量持续收到的服务请求,这些请求必须在满足服务质量(QoS)参数的同时,在尽可能短的时间内进行优先级排序和处理。考虑到云组合问题中分配问题的NP难性质和动态性,强烈推荐使用启发式和元启发式求解方法来获得最优或接近最优的解决方案。本研究提出了一种创新的、高效的方法,用于在考虑QoS的情况下进行制造和物流服务的相互组合。本文提出的方法在高效解决大规模服务组合问题的同时,能够满足最优差距,具有很高的能力。合成了一个样本数据集,以评估与早期研究相比所开发模型的结果。结果表明,所提出的算法因其在解决时间方面的效率,可应用于满足制造和物流服务组合的动态行为。本文在求解算法中嵌入了云服务组合的任务与物流服务的关系,提高了匹配服务的效率。此外,考虑到新服务和需求进入云的可能性,所提出的算法对服务组合算法进行了调整。
