Abstract— Transformation of traditional manufacturing
into intelligent manufacturing has intrigued the manufacturing
firms at a global level. The focal objective of the concept of
Industry 4.0 is to distinguish highly digitized manufacturing
processes where flow of information amid different devices is
controlled in an environment with very limited human
intervention. Different and complex physical and cyber
technologies make Industry 4.0 a way to improve performance,
quality, controllability, management and transparency of
information of manufacturing processes. Although Industry 4.0
provides numerous potential opportunities to manufacturers,
most firms still lack insight into the variety of technologies
available in Industry 4.0 as well as the challenges and risks it
poses to the society with its implementation. This paper
summarizes the available technologies by reviewing existing
studies on it, identifies challenges linked to Industry 4.0 and
provides guidance to implementing smart factory in the context
of Industry 4.0.
Keywords—Industry 4.0, IoT,
manufacturing, Smart factory.

I. INTRODUCTION
Industry 4.0, also known as the Fourth Industrial
Revolution, is characterized by a rapid evolution of
digitization and robotics in manufacturing processes [1]. This
has led to a significant impact not only on supply chains,
business models and business processes but society as well.
By using smart technologies such as Internet of Things (IoT),
Cloud Computing and Big Data Analytics, provision of
seamless connectivity, interoperability and intelligent
capabilities have enabled manufacturing industries to meet
market demands through tailored and customized production
[2], [3]. However, this disruptive change also represents risks
and challenges among the potential opportunities for
companies to adopt and innovate strategic advantage using
these technologies [1], [4].
IoT is the next technological marvel enabling connectivity
and information exchange between objects through the use of
network-connected ubiquitous devices reducing human
interaction. Firms are looking for the exploitation of business
opportunities that come from the application of these new
technologies to new markets [5]. It is also argued that IoT can
enhance
analytical
skills,
software
development,
infrastructure management and performance of the employees
through
behavioural
monitoring
and
enhanced
communications [4], [6]. In an attempt to understand the
efficient use of IoT in manufacturing industry, it is imperative
to recognize the different technologies that make the
performance of manufacturing firms efficient using Industry
4.0.

Unlike internet, which has a well-documented design,
architecture and infrastructure, IoT is considered to be an
extension of internet, although it lacks global coherence. This
raises issues primarily related to data security and privacy,
creating implicit assumptions that data will be shared among
things, applications and possibly sectors. Currently, academia
has given a lot of attention to Industry 4.0 based supply chain,
with main focus on different areas such as sustainability,
organisational structure, lean manufacturing, product
development and strategic management within the
manufacturing industry. Majority of these studies focus on the
contributions and threats of IoT related to flexibility,
transparency, information sharing, connectivity, traceability
and tracking within Industry 4.0. Although, comprehensive
work has been done in these areas, it has been found that most
firms still lack in-depth insight into the different types of
technologies associated with Industry 4.0, and challenges as
well as resources needed for successful implementation of a
smart factory. This paper tries to fill this gap by identifying
available different technologies of Industry 4.0 and
identifying the requirements and key challenges associated
with implementing a smart factory in the context of Industry
4.0. In addition, this paper reviews existing research that has
been done on Industry 4.0; therefore provides a broad
overview of the extant literature on Industry 4.0, summarizes
risks and challenges of implementing a smart factory, and
creates an agenda for future research that encompasses the
vigorous evolution of Industry 4.0.
II. INDUSTRY 4.0
Originating from Germany in 2011, the term ‘Industry 4.0’
was used to label the strategic German industrial policy that
promoted computerization of manufacturing [11]. Industry 4.0
instantly developed to be the focus of German government
and is now being used globally indicating self-sufficient
manufacturing processes, by using machines and devices that
Fig. 1. Four Industrial Revolutions [15].
communicate with each other through digital interconnectivity
[12]. Fig. 1 illustrates the differences between the four
industrial revolutions.
Extensive use of internet is one of the founding pillars of
Industry 4.0, which serves as a passageway to connect
machines, devices, sensors and people. In addition, it aides in
the creation of new product information and features due to
the ability of using internet as a source to gain real time
information [13]. As a result, huge volumes of sensor data in
the form of diagnostics and predictive maintenance collected
from multiple locations and plants will help in reduction of
maintenance costs [14], increase in asset availability and
creation of new usage-based business models [11], [15].
Technological advancements and innovations in business
models have an impact on firm performance and long-term
sustainability [1], [2].
The focal objective of the concept of Industry 4.0 is to
distinguish highly digitized manufacturing processes where
flow of information amid different devices is controlled in an
environment with very limited human intervention [1], [16] .
The term Industry 4.0 signifies the integration of CyberPhysical System (CPS) with the production processes, thereby
altering business paradigms and production systems [12],
[16]. The key distinction between Industry 4.0 and ComputerIntegrated Manufacturing (CIM) is that Industry 4.0 enables
industrial production to achieve a quality leap by connecting
people, machines and machines [8], [9], [16] . Therefore, an
upsurge in new production systems with quick and more
targeted information exchange has been created [11], [17].
III. KEY TECHNOLOGIES IN INDUSTRY 4.0
Industry 4.0 is heavily dependent on use of technology in
different processes. The four main drivers of Industry 4.0 are
IoT, cloud computing, big data and analytics and robotics [8],
[11] as illustrated in Fig.2. Key technologies are discussed in
this section.
A. Cyber-Physical Systems (CPS)
CPSs work to automated exchange of information by
using globally accessible information and communications
network in which production and processes are matched [18],
[19]. According to [19], CPSs are networks of IoT devices that
contain small sensors and actuators that regulate, multiple and
distribute artificial intelligence in industries [1], [8]. These
sensors and actuators are mounted as embedded systems in
different materials and machine parts, which are then
connected with each other through the internet [9], [16]. Use
of these sensors in CPSs enabled machines helps to discover
failure occurring in machines and automatically prepare for
fault repair actions on CPSs. In addition, each workstation is
utilized to an optimum level with the help of cycle time
required for the operation performed on that station [11].
Hence, CPSs merge the physical world with digital world, by
gathering and exchanging data over the internet [15].
Following are the main features of CPS:
Decentralization allows the CPSs own decision
making and autonomous task performance [15], [17].
Interconnections between different devices and
equipment allow the machines, devices, sensors and
people to connect and communicate with each other
[8], [11].
Information transparency is the accessibility to huge
amounts of data that is produced by digital plant
models and sensors and is stored as a virtual copy in
the physical world [15], [19].
Technical assistance allows digital systems to aide
humans in informed decision making and solving
urgent problems on short notice by intensively
accumulating and visualizing information gathered
from sensor data [11], [19].
B. Cloud Computing
Cloud computing has taken digitalization of
manufacturing processes to a new level through heightened
data management and storage abilities [15], [20]. Therefore,
cloud computing has delivered more consistent services in
terms of virtualized storage technologies which serve as data
centres [16], [19]. These storage platforms are located
globally, are concealed in the background and receive data
from ubiquitous devices and sensors, which is then analysed
and interpreted to allow users easy to comprehend web-based
virtualization [11]. In cloud computing, on-demand selfservice features are proven to be essential for the enterprises
in terms of reducing costs, providing flexibility to the system,
increase in profits and competitiveness [2], [15]. Therefore,
cloud offers an flexible solution for data application in terms
of storage space and computing ability which can be changed
on demand [8], [19].
C. Big Data Analytics
Big data is another key enabling technologies in Industry
4.0, where manufacturers leverage data created throughout
their processes [21]. Adoption of data mining techniques by
manufacturers is not a recent process. Manufacturing
companies distributed globally have found significance in
increasing potential of using big data analytics [1], [21]. These
firms own several manufacturing plants generating huge
amounts of data which can be analysed to improve process
efficiency, product quality, speed up cost reduction, value
addition and better services of production optimization [11],
[21].
Fig. 2. Industry 4.0 Technologies [15].
D. Robotics
The need to increase product quality, enhance safe
production environment and quick response to changing
customer demands are some of the motivating factors behind
the development of advanced industrial automation, although
it has long been linked with the increase in manufacturing
productivity [19], [22]. The demand for more flexibility on the
manufacturing plant requires innovative robotic technologies
that allow manufacturers to handle large amounts of
variability in products easily [4], [6].
Robotics, a base technology of Industry 4.0, which serves
as high-level building blocks with the aim of composing a task
or completing a robot program [6], [23]. Using their sensory
devices, robotics use object recognition and pose estimation
functions to detect low-level parameters, therefore performing
the tasks which are considered difficult or unsafe for human
workers. Hence, use of robotics enables the manufacturing
firms to experience enhanced performance, both in
operational as well as production processes [16], [19], [23].
E. WSNs
The true feature of an Industry 4.0 adopted smart factory
lies in its capability to readjust and evolve along with the
growing needs of the organization [7], [13], [14]. These needs
can be categorized into the changing customer demands,
emergence of new markets, development of new products and
services, enhanced productive approaches to operations and
use of advanced technologies in maintenance processes [4],
[13]. The ability to tailor and learn from real time data makes
the smart factories more receptive and predictive to avoid
operational downtime and other possible failures in the
processes [19]. The sensors, in the form of WSNs, in
production phase enable the smart factories to monitor
specific processes throughout the factory which enhances
awareness on what is going on at multiple levels [11]. A
mobile platform offering high speed and low cost
communications anywhere and anytime can be achieved
through Wi-Fi, Bluetooth and WiMAX in smart factories [2],
[16].
F. RFID
Besides sensors, several RFID applications have been
successfully implemented in smart factories. It has the
capability to disclose information of the product at a low level
in an autonomous, instantaneous and touchless method [13],
[14]. Unlike barcodes, RFID tags do not need a direct line of
vision to transmit data, making it likely to scan different tags
as a batch synchronously. Information visibility can be
enhanced using RFID at different stages of a business supply
chain including acquisition of raw materials, manufacturing,
logistics and retail [7], [15]. Reduced uncertainty as a direct
result of information visibility and transparency is one of the
most probable benefits of RFID.
G. M2M
Traditionally, technologies where integrated with
physical components at a rapid rate, however now IoT and
machine-to-machine (M2M) are rapidly incorporating data
and system flows that form the foundations of the global
economy at an alarming speed and accuracy [1]. Fixed
broadband technologies are restricted to household
implementations around the developed world, while on the
other hand, a mobile broadband platform places electronic
devices to almost 4 billion end users by connecting billions
of new devices across the globe [4], [22].
IV. IMPACT OF INDYSTRY 4.0 ON SOCIETY
The real-time dynamic of data analytics, the basis of
manufacturing industries, is giving rise to new opportunities
and challenges for business leaders. In order to have a
continuously working complex smart factory environment,
both smart hardware and software is necessary for a smart
factory. However, some underlying technical and nontechnical issues have to be addressed.
A. Cyber Security
Billions of smart assets, when networked together to store
information on the cloud, become exposed to cyber security
risks [1], [19]. These cyber risks pose threats ranging from
personal devices to complex IT systems, making both
individuals and organizations vulnerable to financial and
operational damages [13], [14]. In addition, a bad data injected
into the smart system has the potential to be as damaging as
data extracted from the system through a data breach.
Therefore, both the systems and the communications need to
be secure, as huge number of systems communicated with
each other over vast distances, making them vulnerable to
security breaches.
B. Impact on Jobs
The role of employees will continue to evolve from what
they are actually doing in today’s factories, as the smart
factory continuously evolves. As automation will take up the
tasks that are repeated, mundane or impacted by labour
shortage, people will take on more complex roles in these
factories [2], [11]. In addition, special skills and knowledge
will be required to fill top managerial positions in smart
factories. For example, IT managers with no skills in smart
manufacturing face problems in meeting deadlines. A huge
skills gap will be created with the retirement of experienced
and skilled workers [17].

C. Human Behavioural Intentions on the Adoption of IoT
Despite unpredictable circumstances, trust plays a vital
role to encourage people to adopt modern technology [1], [2],
[19]. In uncertain situations, trust helps the users of this
technology to recognise the social surroundings of the
technology, therefore decreasing vulnerability [4], [7]. Studies
have shown that trust significantly enhances the behavioural
intention of people to adopt IoT products and services,
whereas lack of trust may result in difficulty to spread the IoT
systems among people [7], [11], [13], [14].
D. Interoperability and Standardization of IoT
Interoperability of IoT plays a vital role in producing
around 40% of potential value developed by IoT in different
settings [22]. In an environment where countless devices of
different types and technical profiles will operate (e.g. from
autonomous vehicles to drones), manufactured by thousand
different brands (each with their standards), developing the
ability for them to communicate with each other will be a
technical challenge [16]. This interoperability and lack of
standardisation of IoT devices may lead to individuals and
businesses to have unequal access to data of value from the
IoT [11]. In addition, these issues may lead to manufacturers
and users of IoT to be confused over a huge network of
platforms available.
V. CONCLUSION
This paper has discussed different types of IoT
technologies used in Industry 4.0. A comprehensive review of
the existing literature is also presented on technology-lead
smart factories. Societal impact of Industry 4.0 in terms of
cyber security, job market, behavioural intents on technology
adoption and interoperability & standardisation are
investigated. Industry 4.0 exploits new technologies including
IoT, CPS, cloud computing, big data analytics, artificial
intelligence and robotics. With the help of these technologies,
data flow is integrated horizontally between partners,
suppliers, customers as well as organizations to develop a
finalized product according to the customer demands.
Therefore, the developing trend of a smart factory is humanmachine collaboration, where major decisions are made by
humans.
Although Industry 4.0 promises an endless range of
benefits for manufacturing firms, there are some underlying
challenges faced by these firms in implementing IoT.
Therefore, implementing smart factories should take into
account interoperability, vulnerability, decentralization,
virtualization and real-time capability. Risks are mostly
associated with eventual job losses, privacy and lack of
standardization of IoT.
With continuous evolution of IoT devices, there is a vision
of IoT in which the future-generation internet will stimulate
the interaction between human, societies and smart things
giving rise to a new phenomenon known as Opportunistic IoT
[14]. The Opportunistic IoT addresses the link formed within
different communities (by pairing devices) created by the
opportunistic contact nature of humans and, therefore, focuses
on the human side of IoT [11], [16]. This side of IoT can prove
to be a revolution in future research studies on the impacts of
IoT applications. In addition, it is vital to study the behaviour
of users adopting IoT into their everyday life and how using
this advanced technology is affecting their behaviour. This has
given rise to behavioural IoT, which includes ethical issues
related to the implementation of IoT devices such as data
security, right to private life and rights on information sharing.
These issues need to be taken into account for future studies.
