Ontology for colaborative development of product service systems based on basic formal ontology 基于基本形式本体的产品服务系统协同开发本体
A. Correia, D. Stokic, Rebecca Siafaka, S. Scholze
The paper is one of the few attempts to develop a Product Service System (PSS) ontology aiming to facilitate Knowledge Management in collaborative PSS design, focusing upon machine industry. The PSS ontology includes concepts such as products, services, PSS, PSS lifecycle, process and stakeholders, including direct customers, consumers and their feedback. The context sensitivity approach is proposed to fully support the use of different tools for PSS development by various stakeholders. The context model includes both PSS ontology and a so-called user-centric ontology. The process to develop the ontologies is described. The approach to build the PSS ontology is based on the so-called Basic Formal Ontology (BFO). The foreseen applications of both ontologies in industrial practice of machine vendors and the expected benefits are being elaborated.
本文是为数不多的以机械工业为研究对象,开发产品服务系统(PSS)本体的尝试之一,旨在促进协同PSS设计中的知识管理。PSS本体包括产品、服务、PSS、PSS生命周期、流程和涉众(包括直接客户、消费者及其反馈)等概念。提出上下文敏感方法是为了充分支持不同利益相关者使用不同的工具进行PSS开发。上下文模型包括PSS本体和所谓的以用户为中心的本体。描述了开发本体的过程。构建PSS本体的方法基于所谓的基本形式本体(Basic Formal ontology, BFO)。对这两种本体在机器供应商工业实践中的预期应用和预期收益进行了阐述。

Modelling and simulation of economic lot size scheduling problem: A case study 经济批量调度问题的建模与仿真:一个案例研究
Mohammed M. El-Beheiry, K. Abdallah
Economic Lot Size Scheduling Problem (ELSP) is one of the most challenging problems in production and operation management. Although studied extensively in the literature, yet it is still one of the major topics in scheduling research. ELSP with its various configurations can be found in many industrial fields. In this paper, a producer of Fast Moving Consumer Goods is considering this decision. The company has a production line producing a range of products having dependent changeover cost. It is required to determine the production schedule and lot size that minimize the total cost. We provide a heuristic model that uses different priority rules, and simulate the model to compare the performance against the different priority rules at different lot sizes. The total cost is calculated finding that the Safety Time rule resulted in the least cost among tested rules. The effect of different cost parameters on the priority rule performance is also discussed leading to defining cost ratio determining the superiority of the used rule.
经济批量调度问题是生产经营管理中最具挑战性的问题之一。虽然文献对其进行了广泛的研究,但它仍然是调度研究的主要课题之一。ELSP的各种配置可以在许多工业领域找到。在本文中,一个快速消费品生产商正在考虑这个决策。公司拥有一条生产线,生产一系列具有独立转换成本的产品。需要确定生产计划和批量大小,使总成本最小化。我们提供了一个使用不同优先级规则的启发式模型,并对该模型进行了仿真,以比较不同批次大小下不同优先级规则下的性能。计算总成本,发现安全时间规则在所有测试规则中产生的成本最小。还讨论了不同成本参数对优先规则性能的影响,从而确定了成本比,确定了所使用规则的优越性。

Managing disruptions during the execution phase of product development projects: A secondary data analysis 管理产品开发项目执行阶段的中断:辅助数据分析
Fausto Guaragni, K. Paetzold, R. Ortt
Product development processes are most of the times linear and hardly adapt to exogenous influences, especially when they happen after the planning phase has ended and the project is already in its execution phase. However, the more disruptive the exogenous events are, the more a company requires resources in order to overcome them. Efforts may not only be required from the product development team, solutions from an operational perspective only would present a limited vision on the problem itself. While these disruptive events require multidisciplinary studies in order to be fully comprehended, most of the literature contributions consider only one or few perspectives. This research aims to identify which aspects are needed in a case study in which an event disrupted an ongoing development process.
产品开发过程大多数时候是线性的,很难适应外部影响,特别是当它们发生在计划阶段结束后,项目已经进入执行阶段。然而,外生事件的破坏性越大,公司就越需要资源来克服它们。可能不仅需要产品开发团队的努力,从操作角度出发的解决方案只会对问题本身提出有限的看法。虽然这些破坏性事件需要多学科研究才能被充分理解,但大多数文献贡献只考虑一个或几个观点。这项研究的目的是确定哪些方面需要在一个案例研究中,其中一个事件打乱了正在进行的开发过程。

Towards cooperative ESS for distribution systems with high penetration of RES and EV the Storage4Grid vision 面向可再生能源和电动汽车高渗透配电系统的合作ESS: Storage4Grid愿景
Jinyong Fu, R. Tomasi, M. Fantino, M. Spirito, Mihai Sănduleac, Veronika Krauß, Otilia Werner-Kytölä, G. Thybo, Giovanni Paolucci
Storage4Grid (S4G) is a 36-months project funded by the European Commission under the call LCE-01-2016, area 1 (Storage). S4G proposes an innovative holistic methodology for modelling, planning, integrating, operating and evaluating distributed Energy Storage Systems (ESS) including storage at user premises and storage at substation level, Electrical Vehicles (EV), innovative energy metering and energy routing technologies. This paper presents a systematic strategy used by S4G to generate the use cases for two scenarios related to two test sites: in Bolzano focused on cooperative EV charging and in Fur addressing the impact of user and grid side storage coordination to the medium and low voltage distribution network. The paper summarizes the S4G vision, solutions, and approaches for evolving the cooperative and coordinated ESS scenarios into use-cases and related requirements.

Periodic scheduling of mixed workload in distributed systems 分布式系统中混合工作负载的周期调度
Georgios L. Stavrinides, H. Karatza
Efficient scheduling of jobs in distributed systems is essential to achieving good performance. This paper addresses issues of scheduling a job mix, consisting of parallel jobs and single-task, but computationally intensive jobs, on distributed processors. It considers a scheduling algorithm, referred to as periodic scheduling. With this algorithm, processor queues are rearranged only at the end of predefined time intervals, called periods. The goal is to examine whether periodic scheduling can significantly reduce the overhead that is involved with the corresponding non-periodic policy and to also provide good performance. Simulation is employed to evaluate the performance of this algorithm for different period sizes. Simulation results demonstrate that periodic job scheduling can meet the goal.
分布式系统中作业的高效调度是实现良好性能的关键。本文讨论了调度作业组合的问题,包括并行作业和单任务,但计算密集型的作业,在分布式处理器上。它考虑了一种调度算法,称为周期性调度。使用此算法,处理器队列仅在预定义的时间间隔(称为周期)结束时重新排列。我们的目标是检查周期性调度是否可以显著减少相应的非周期性策略所涉及的开销,并提供良好的性能。通过仿真对该算法在不同周期长度下的性能进行了评价。仿真结果表明,周期作业调度能够满足目标要求。

To be or not to be an engineer? – Perceptions among 3rd cycle basic school students 做工程师还是不做工程师?-第三周期基础学校学生的看法
Ana Margarida Trigo, C. Leão, F. Soares
The present study analyses the perception of students before university application, in Portugal. Basic education qualification (9th year of schooling) is considered the general education in Portugal, since students do not have to make choices about their future. At the end of 9th year, students will choose if they want to pursue their studies in arts, science and technology or humanistic areas or if they want to enroll in professional studies. This explains the application of questionnaire in classes of 9th grade to analyze students' perception about engineering profession and STEM careers. To the best of the authors' knowledge, this is the first paper in the scientific community, concerning the study of engineering perception in Portuguese basic schools. This first intervention allows concluding that there is a lack of motivation to endorse engineering courses.
本研究分析了葡萄牙学生在申请大学前的认知。基础教育资格(第9年的学校教育)在葡萄牙被认为是通识教育,因为学生不必为自己的未来做出选择。在第9年结束时,学生将选择是否要继续在艺术,科学和技术或人文领域的学习,或者如果他们想参加专业学习。这就解释了在九年级班级中使用问卷来分析学生对工程专业和STEM职业的认知。据作者所知,这是科学界第一篇关于葡萄牙基础学校工程感知研究的论文。这第一种干预可以得出结论,即缺乏支持工程课程的动机。

Situation awareness in the Internet of Things 物联网中的态势感知
B. Mozzaquatro, R. Jardim-Gonçalves, C. Agostinho
Business opportunities have been benefited with the popularization of wireless devices of the Internet of Things (IoT). Several security issues can produce drawback to the companies because of Internet technologies did not designed to support IoT as well as information disclosure, privacy issues, and cyber threats. However, these situations of the interest could provide knowledge about the reality of the IoT environment. The monitoring of the elements status of a system involves the Situation Awareness (SA) paradigm. However, a limitation of this model is that SA is awareness held exclusively by the human. In this paper, we propose the adoption of a reference ontology to enhance cybersecurity in the IoT considering SA. An ontology extension is used to deal with distinct situational sources and enrich the meaning around security issues. To validate this proposal we describe a case study considering the data collection from smart objects in a metalworking company.
随着物联网(IoT)无线设备的普及,商业机会已经受益。由于互联网技术并不是为支持物联网而设计的,而且信息泄露、隐私问题、网络威胁等问题也会给企业带来不利影响。然而,这些感兴趣的情况可以提供有关物联网环境现实的知识。监视系统的元素状态涉及到情境感知(Situation Awareness, SA)范式。然而,这个模型的一个局限性是SA是人类独有的意识。在本文中,我们提出采用参考本体来增强考虑SA的物联网中的网络安全。本体扩展用于处理不同的情景源,并丰富围绕安全问题的含义。为了验证这一建议,我们描述了一个案例研究,该案例考虑了金属加工公司中智能对象的数据收集。

Configuring and visualizing the data resources in a cloud-based data collection framework 在基于云的数据收集框架中配置和可视化数据资源
Wael M. Mohammed, Borja Ramis, J. Lastra
The Manufacturing Enterprise Solutions Association (MESA) provided the abstract and general definition of the Manufacturing Execution Systems (MES). A dedicated function has been reserved for the data collection activities. In this matter, the Cloud Collaborative Manufacturing Networks (C2NET) project tends to provide a cloud based platform for hosting the interactions of the supply chain in a collaborative network. Within the architecture of the C2NET project, a Data Collection Framework (DCF) is designed to fulfill the function of data collection. This allows the companies to provide their data, which can be both enterprise and Internet of Things (IoT) devices type of data to the platform for further use. The collection of the data is achieved by a specific third party application, i.e., the Legacy System Hub (LSH). This research work presents the approach of configuring and visualizing the data resources in the C2NET platform. This approach employs the web-based applications and the help of the LSH. This permits the C2NET platform to adapt to any kind of third party application, which manipulates enterprise data, following the generic and flexible solution of this approach.
