Distributed manufacturing systems have become consensus, particularly networked manufacturing systems (NMS) owing to its flexible and adaptable nature in response to customized requirements. Highlighting of functions in NMS and their integration with recent key enabling technologies i.e., Artificial intelligence, Machine learning, Internet of Things, Block chain technology, and Agent-based techniques, etc. are of utmost importance to identify problems and increase its efficiency. Hence, besides the above-mentioned approaches, this paper surveyed and analysed various articles systematically related to networked manufacturing in the context of knowledge creation and information, security, interoperability, and reliability. To identify the most related papers, the search has been conducted with Web of Science and Scopus databases. Subsequently, after evaluation 30 most related papers were selected and analyzed that further extended by identifying the issues and gaps in the existing empirical knowledge. Finally, the paper presents a roadmap for future research directions and developments.

The paper presents two original and innovative contributions: 1) the model of machine learning (ML) based approach for predictive maintenance in manufacturing system based on machine status indications only, and 2) semi-Double-loop machine learning based intelligent Cyber-Physical System (I-CPS) architecture as a higher-level environment for ML based predictive maintenance execution. Considering only the machine status information provides rapid and very low investment-based implementation of an advanced predictive maintenance paradigm, especially important for SMEs. The model is validated in real-life situations, exploring different learning algorithms and strategies for learning maintenance predictive models. The findings show very high level of prediction accuracy.

Complex systems consist of multiple machines that are designed with a certain extent of redundancy to control any unanticipated events. The productivity of complex systems is highly affected by unexpected simultaneous machine failures due to overrunning of machines, improper maintenance, and natural characteristics. We proposed realistic configurations with multiple machines having several flexibilities to handle the above issues. The objectives of the proposed model are to reduce simultaneous machine failures by slowing down the pace of degradation of machines, to improve the average occurrence of the first failure time of machines, and to decrease the loss of production. An approach has been developed using each machine’s degradation information to predict the machine’s residual life based on which the job adjustment strategy where machines with a lower health status will be given a high number of jobs to perform is proposed. This approach is validated by applying it in a fabric weaving industry as a real-world case study under different scenarios and the performance is compared with two other key benchmark strategies.

Sustainability in project management is an emerging and evolving field of study, in the 2030 Agenda for Sustainable Development. Sustainability in project management is immersed in many goals and targets, and is also echoed in many other goals and targets. In this sense, the goal of this research was to analyse how to incorporate sustainability issues and Sustainable Development Goals – SDGs as critical success factors for project management and propose a sustainable project management model. The developed conceptual model contains the variables related to the identified barriers and motivation factors for the integration of sustainability with project management. It presents seven hypotheses and five constructs: Sustainable Development Goals; Interested Parties; Sustainable Companies; Sustainable Project Management Methodology and Sustainable Project. The proposed model and its constructs’ relationships were validated using a structural equation model, across more than 400 valid questionnaires, completed by project management professionals from all around the world. The main result of the study indicates that for sustainability to become an integer part of project management, the dissemination and use of a sustainable project management methodology that considers the SDGs – Sustainable Development Goals by companies and professional associations, encouraging professionals to be trained and certified in these sustainable methodologies, is necessary.

Research on flexible unit systems (FUS) with the context of descriptive, predictive, and prescriptive analysis have remarkably progressed in recent times, being now reinforced in the current Industry 4.0 era with the increased focus on integration of distributed and digitalized systems. In the existing literature, most of the work focused on the individual contributions of the above mentioned three analyses. Moreover, the current literature is unclear with respect to the integration of degradation and upgradation models for FUS. In this paper, a systematic literature review on degradation, residual life distribution, workload adjustment strategy, upgradation, and predictive maintenance as major performance measures to investigate the performance of the FUS has been considered. In order to identify the key issues and research gaps in the existing literature, the 59 most relevant papers from 2009 to 2020 have been sorted and analyzed. Finally, we identify promising research opportunities that could expand the scope and depth of FUS.

Various companies choose to outsource the delivery of part of their services, so as not to deviate from its core business and improve the service level. This approach leads to a new type of organizations, so-called networked and virtual enterprises, where possibly a great number of companies work together without having direct contact but through a broker, as an intermediary, that streamlines the relationships between them. To enable high level efficiency, as well as some other functional requirements, the meta-organizations and brokering services are conceived as environments and services for networked and virtual enterprises operation and dynamic reconfigurations, representing a model of organizations-of-organizations, as an implementation of one of the Industry 4.0 models and ecosystem for networked and virtual enterprises dynamic reconfiguration. In this paper, the meta-organizations with embedded brokering services, modelled as call centres, are analyzed. Various simulations are presented, based on Erlang's formulas for some of design and performance measures parameters evaluation, such as service level, average waiting time, agent occupancy and service traffic intensity.

Goal: The main goal of this research is to analyse the behaviour of a set of ten lot-sizing methods applied to different application scenarios, within the context of more traditional MRP-based manufacturing environments and on JIT/ Kanbans oriented ones. Design/Methodology/Approach: After an extended literature review, a quantitative research method is used to provide a comparative analysis on the performance of the lot-sizing methods under different simulated application scenarios, with variations in demand and peaks of seasonality. Moreover, a final summary provides the error deviations for lot-sizing methods regarding increases in demand variations and seasonality indexes. Results: The study analyses lot-sizing methods and discusses benefits and risks associated to its use in application scenarios marked by a considerable variation in demand or peaks in seasonality. Limitations of the investigation: As the application scenarios did not explore variations in the ordering and stock holding costs, further analysis including these kinds of variations is encouraged. Practical implications: The findings of this research enable the enhancement of the conscience of industrial practitioners, regarding the selection of best suited lot-sizing methods for being applied on each kind of manufacturing scenario, regarding MRP or JIT/ Kanban environments. Originality/Value: Given the diversity of the existing lot-sizing methods, for instance, the heuristic ones, authors can find it quite difficult to select appropriate methods for solving their problems for each kind of application scenario. Therefore, the present study can provide useful knowledge to better support decision making in the lot-sizing domain.

Experiential learning model for acquiring skills on CAD Systems interoperability, using the Social Networked-based Education model and the Learning Factory platform, is presented. The experiential learning leads students to acquire knowledge on CAD Systems interoperability through the principle of “Project-first, just-in-time principles”. The experiential learning is applied in Computer Aided Design/Computer Aided Process Planning (CAD/CAPP) and Computer Aided Manufacturing (CAM) curricular units, within the fourth year of Integrated Master on Industrial Engineering and Management course and along seven years in row. The experiential learning model developed and implemented proved that experiential learning provides capacity of teaching of new features and experience of Industry 4.0 environment while keeping the actual “curricula”.

A contribution to the definitions of Sequential Engineering (SeqE), Simultaneous Engineering (SE), Concurrent Engineering (CE), and Collaborative Engineering (ColE) is presented. The need for contribution to better clarification of the referred engineering and design concepts, and approaches, is because there are identified many problems in definitions found in the literature that generate misinterpretations about the underlying semantic contents presented. Among others, the most frequent problems are 1) keeping the same denominating term, or syntagm, for different semantic contents, implying different definitions, and 2) using different denominating term, or syntagm, for the same semantic contents, implying same definitions. At the end, the paper presents the table with the corresponded main, or global, “signature” attributes, along with the argumentation, distinguishing clearly all four engineering and design concepts SeqE, SE, CE, ColE.

Nowadays, Lean Manufacturing, Industry 4.0, and Sustainability are important concerns for the companies and in a general way for the society, principally, the influence of the two production philosophies, Lean Manufacturing and Industry 4.0, in the three main pillars of sustainability: economic, environmental, and social. According to the literature review done in this work, these relations are not well known and are dispersed by different sustainability’s criteria. To address this gap, this research proposes a structural equation model, with six hypotheses, to quantitatively measure the effects of Lean Manufacturing and Industry 4.0, in Sustainability. To statistically validate such hypotheses, we collected 252 valid questionnaires from industrial companies of Iberian Peninsula (Portugal and Spain). Results show that: (1) it is not conclusive that Lean Manufacturing is correlated with any of the sustainability pillars; and (2) Industry 4.0 shows a strong correlation with the three sustainability pillars. These results can contribute as an important decision support for the industrial companies and its stakeholders, even because not all the results are in line with other opinions and studies.

Sajber-Fizički Proizvodni Sistemi (SFPS) su inherentni Industriji 4.0 kako bi se unapredili aktuelni procesi upravljanja i kontrole proizvodnim sistemom, a samim tim i proces donošenja odluka. Ovaj rad predstavlja istraživanje uticaja vremena trajanja donošenja odluka u SFPS na performanse proizvodnog sistema, za različite paradigme planiranja proizvodnje. Ispitivani su različiti scenariji s obzirom na različita vremena trajanja odlučivanja i različite varijacije dinamike okruženja. Rezultati pokazuju da se sa povećanjem vremena trajanja odlučivanja povećava vreme završetka poslova datih na ulazu, kao jedna od glavnih mera performansi proizvodnog sistema. Takođe, uzimajući u obzir stabilna okruženja, rast varijacije vremena završetaka u funkciji vremena trajanja odlučivanja SFPS-a je približno linearan, dok je u slučajevima dinamičkih okruženja rast varijacija vremena završetaka u funkciji vremena trajanja odlučivanja CPPS-a nelinearan.

Cyber-physical systems are often misunderstood to be just any embedded systems. The real cyber-physical system should have both physical and digital (computational-communication-control) parts inter-connected in each part and process, and the system itself should have the capacity to change its own behaviour to adapt to changing requirements. This paper presents an architecture of an intelligent cyber-physical system where a reconfigurable manufacturing system is supported by a machine learning algorithm to provide enhanced decision-making to the manufacturing control system. Experiment results are presented showing the machine learning module can help the control system adjust itself with changing requirements provided externally (by a user) in the form of training examples. The result is an architecture of an intelligent cyber-physical system, with physical and digital parts always working in synchronization, enabling change in the system's behaviour in terms of manufacturing process-flow in order to adapt to any change in the production planning.

Each time a relevant proposal occurs, existing perspectives, concepts or fundamentals are confronted by emergent ones. The Industry 4.0 and its promoted production control systems based on Cyber-Physical Systems (CPS), made splash new potentials for the binomial human and technology (equipments and its settings). Several authors explore the envisaged required more physical and digital connection to announce interesting transformative changes, where self-configure and adaptive machines sustain the application of corrective decisions. This paper exposes a spectrum of existing CPS definitions and models and contributes with the fundamentals for an effective intelligent CPS (I-CPS), where a double loop learning process, allows its supporting software algorithms to be changed or reprogrammed. Instead, not only self-configure machines but its configuring software, too.

Sajber-Fizičkih Sistema (SFS) uspostavlja međuzavisnost fizičkog sveta i sajber sveta. Pri razmatranju stvarnog sveta, SFS će dobiti značajne ulazne podatke iz fizičkog sveta koji zahteva pravovremeni odgovor. Bez kompjuterskih kapaciteta za obradu ulaznih podataka, SFS neće biti u mogućnosti da reaguje u kratkom roku na promene u okruženju i obezbedi odgovarajuće izlazne podatke. Sadašnji SFS nisu u stanju da reaguje u realnom vremenu na izazove prilikom razmatranja problema realnih obima. Cilj je da iskoristimo performanse računarskih sistema visokih performansi kako bismo učinili SFS sposobnim da odgovori potrebnim računarskim zahtevima kako bi bili u mogućnosti da operišu u interakciju sa fizičkim svetom. Predstavljena je studija slučaja o algoritmima programiranja proizvodnje kako bi se pokazala trenutna ograničenja u performansama računanja i ukazali na moguća rešenja da bi se ciljevi postigli.

Technological evolutions lead to changes in production processes; the Fourth Industrial Revolution has been called Industry 4.0, as it integrates Cyber-Physical Systems and the Internet of Things into supply chains. Large complex networks are the core structure of Industry 4.0: any node in a network can demand a task, which can be answered by one node or a set of them, collaboratively, when they are connected. In this paper, the aim is to verify how (i) network's connectivity (average degree) and (ii) the number of levels covered in nodes search impacts the total of production tasks completely performed in the network. To achieve the goal of this paper, two hypotheses were formulated and tested in a computer simulation environment developed based on a modeling and simulation study. Results showed that the higher the network's average degree is (their nodes are more connected), the greater are the number of tasks performed; in addition, generally, the greater are the levels defined in the search for nodes, the more tasks are completely executed. This paper's main limitations are related to the simulation process, which led to a simplification of production process. The results found can be applied in several Industry 4.0 networks, such as additive manufacturing and collaborative networks, and this paper is original due to the use of simulation to test this kind of hypotheses in an Industry 4.0 production network.

Technology adoption play significant role for good healthcare services. It is very important to understand and identify the requirements and perceptions of hospital employees for the implementation of technology in their work place. This study determines the impact of performance expectancy, effort expectancy and social influence on behavioural intention as well as the impact of facilitating conditions on technical/clinical staff’s perspective. The structured questionnaire is administered to 770 clinical staffs on the usage of telemedicine and electronic health records in hospitals. A valid sample of 568 was returned back for further analysis. Regression analysis using AMOS 20 is performed to examine the effect of the constructs. Findings revealed that performance expectancy, effort expectancy, and social influence have a significant impact on behavioural intention and facilitating condition also significantly impacts behavioural intention which in turn impacts usage behaviour of electronic health records and telemedicine. The limitations and future research are suggested and delineated.
