The smart factory as a key construct of industry 4.0: A systematic literature review

Industry 4.0: current trend and future scope for further research in High Performance Manufacturing

“…The companies need to rethink modeling and analysis to integrate available data [4]. Nonetheless, this is not a new topic, Osterrieder, Budde, & Friedli (2019) establish that since 80´s some authors such Shaw (1983) envisioned a future state of a completely autonomous factory by relying on advanced robotics [5]. The scope of digital transformation in manufacturing is vast and extent to which it occurs is result of several elements combination such as internet, automation, flexibility, adaptability, reconfigurability, modularity, networking, among others, designed and implemented to achieve high performance in companies [6].…”

“…I4.0 develops when the paradigm Internet of Things (IoT) is merged with Cyber Physical Systems (CPS) idea [6] and cloud computing, with the potential of becoming global production language [8] although it is a complex technological architecture that represent a challenge to manufacturing systems [9]. I4.0 is widely used to describe the digital factory concept, where human intervention is reduced to minimum and indispensable [5]. The term I4.0 was introduced in Germany [8] and emerged for the first time in 2011 with the aim to characterizing highly digitized manufacturing processes [5,6] through program called High Tech Strategy 2020, becoming a worldwide movement.…”

In United States, it was established as "Advance Manufacturing Partnership", in China as "Made in China 2025" and in France as a program called "La Nouvelle France Industrielle" [10].…”

“…I4.0 can be defined as technical requirements that support production processes based on technology and devices autonomously, communicating with each other through interoperability, virtualization, decentralization, real time capabilities, service orientation and modularity. This implies five levels, depending of companies´ technology levels (maturity level or Cyber Physical Systems Digital Object Identifier (DOI): http://dx.doi.org/10.18687/LACCEI2020.1.1.303 ISBN: 978-958-52071-4-1 ISSN: 2414-6390 level) [5]: (1) connection level; (2) conversion level; (3) cyber level; (4) cognition level; and (5) configuration level (intelligent production). I4.0 are measured with level and performance of: (1) Interconnection or interconnectivity (speed, mobile connection to internet), (2) Interoperability (Cyber physical systems, machines, assembly lines, sensor), (3) Enterprise (Enterprise Resource Planning, automatically linked to those of their supplier and/or customers, business to business and Government), (4) Virtualization, and (5) Buy high Cloud Computing, Services (Accounting software applications, CRM, Computing power), these allows evaluated I4.0 in two ways: I4.0 infrastructure and big data maturity [9].…”

“…All these variables and indicators are present across different manufacturing practices; Product design, Production planning, Production engineering, Producing products and services, Lean, Technology management, Supply chain management, Operations strategy Quality management [12], Value stream mapping, 5s, Kainzen, Just in time (lean manufacturing along industry 4.0), Pull flow, Machine learning and separation, Human resource and teamwork [11,6]. CPPS are evaluated at technological level across to [10]: (1) CAD/CAM, (2) Integrated engineering system, (3) Digital automation with sensors, (4) flexible manufacturing lines, (5) MES and SCADA System, (6) Big Data, (7) Digital product service, (8) Additive manufacturing and (9) Cloud services.…”
