Abstract:
The purpose of this paper is to
identify and analyze the contributions and barriers
of digitalization and industry 4.0 within supply chain (SC). The paper performs
a systematic literature review through the management research data bases
published between the period of 2012 and January 2021. The paper shows that
digitalization and Industry 4.0 improve firm information system, enhance
management processes and insure competitiveness. However, it also found that the
stigmas left by previous technologies, the lack of industry specific
guidelines, lack of digital skills and talents, or lack of top management
commitment prevent the adoption of these technologies in the SC. The choice
made by limiting analysis on the HCERES journals restricts the scope and future
analysis should enlarge the area.

Résumé :
L'objectif de cet article est d'identifier et
d'analyser les contributions et les obstacles de la digitalisation et de
l'industrie 4.0 au sein de la supply chain (SC). L'article effectue une revue systématique de la
littérature à travers les bases de données de recherche en gestion publiées
entre la période de 2012 et janvier 2021. L'article montre que la
digitalisation et l'industrie 4.0 améliorent le système d'information des
entreprises, améliorent les processus de gestion et assurent la compétitivité.
Cependant, il a également constaté que les stigmates laissés par les
technologies précédentes, le manque de directives spécifiques à l'industrie, le
manque de compétences et de talents numériques ou le manque d'engagement de la
direction empêchent l'adoption de ces technologies dans la SC. Le choix fait de
limiter l'analyse aux revues du HCERES enrestreint le
périmètre et les analyses futures devraient élargir le champ.

The
Fourth Industrial Revolution, i.e. digitalization (Parviainen
et al., 2017) strengthened the firm's organizational capacities by improving
their information systems. This new challenge reorganizes entire production
methods and also affects supply chain activities (Wu et al., 2016, Vetois and Raimbault, 2017).
According to Gartner’s glossary, digitalization is the use of digital
technologies to change a business model and provide new revenue and value
producing opportunities. It is the process of moving to a digital business
(Bloomberg, 2018). It is distinct from digitization which is considered as the
conversion of analogue data into digital form (Parviainen
et al., 2017). While digitalization is more about business operations, digital
transformation (DT) initiatives, will typically include several digitalization
projects and social interactions or business models. But the present research
treats digitalization and digital transformation indifferently, as did Parviainen et al. (2017). These authors admitted that
digital transformation affects organisations in four levels: process,
organization, business domain, society. The study does not analyse the society
level.
Digitalization
is found to be a prerequisite for Industry 4.0. For Couzineau-Zegwaard
(2020), the introduction of Industry 4.0 within the manufacturing has several
impacts on the entire Supply chain (SC). Before this author, Fel et al. (2019), already highlighted this through their
study among a panel of SC practitioners. They found that, three quarters of the
experts investigated, in their study predicted that the firm's SC will be
radically transformed as a result of the hybridization between industry and
services induced by 4.0 technologies. Hence, even maintenance, specification or
update services will have to fit into the same chain. For Parviainen
et al. (2017), with digitalization, costs can be cut by up to 90 percent and
turnaround times improved by several orders of magnitude. Going paperless also
improves data collection and helps manage performance or shed light to cost and
risk drivers.
There
are numerous objectives for digital transformation (Kraus et al., 2022). The
primary aim is to solve challenges concerning efficiency and effectiveness (Heavin and Power, 2018). Hess et al. (2016) state therefore
that companies that do not rapidly develop and implement DT strategies are
unlikely to keep pace and compete in the new digital reality. Digitalization
transformed the entire industry sector, from small to wide range enterprise. If
this is clear for large scale enterprises, it remains less obvious for SMEs
even if many authors prove the evidence of their importance. Analyzing how digital technologies facilitate business
model innovations in the creative industries, Li (2020b) found that its have facilitated pervasive changes in business models. Kirtley and O’Mahony (2020) found
that digitalization helps improve SMEs’ performance. While Müller et al. (2021)
found that digital transformation is changing SMEs’ traditional business model
and customers’ value creation process, Skare et al.
(2023) highlighted that digital transformation strengthens SMEs’ ability and
flexibility to address main business issues. Previously, Khin
and Ho (2019) highlighted that, SMEs use digital technologies to produce new
digital products and services, expand the consumer base, and improve business
performance. They also take the opportunities of easy access of network to
connect with suppliers that meet their requirements in rapidly changing markets
and supply chains (Kergroach, 2021).
The
objective of this paper is to analyze, through a
systematic review of the literature, the contributions and reluctance of
digitalization in supply chains. It aims globally to define what Industry 4.0
is, but also analyses different technologies it abounds. Moreover, it analyses
the industrial fields in which they are deployed, their contributions for the
improvement of industrial and SC practices. Therefore, a systematic review is
realized on the main databases in management science.
The
next section presents the methodology of the literature review. Then, a state
of art on digitalization within industries is presented in section three, as
well as the contributions of digitalization to SC. This section also presents
the barriers to the Industry 4.0 implementation within the SC. The section four
suggests some implications. The final section concludes the paper.
This
paper is built up on a systematic literature review from 2012 and 2021. It
follows methods use by several authors in management science and suitable for
our objectives because it is based on two stages: a systematic literature
review followed by a bibliometric analysis. This approach is called
"Systematic Literature Network Analysis (SLNA)" by Ben-Daya et al. (2019) or Colicchia
and Strozzi (2012). The authors found that this
method is more objective and suitable for studying emerging fields and their
trends.
The
first stage searched for publication titles and abstracts for the initial
downloading of published research literature between 2012 and 2021. This was
made around keywords such as "supply chain digitization",
"Supply chain digitalization" "Industry 4.0", "Block
Chain", "Internet of Things", "Cloud computing",
"Big data", "Cyberphysical
system", "IT in business" in english
and french. The initial query provided 1704 research
papers. In the second step, we restricted the selection to articles published
in the area of business and management as done Kraus et al. (2022). Then, we
selected 778 research papers. We screened the titles, keywords, and abstracts
of the remaining papers to exclude those that were not relevant for achieving
the aim of the paper in step three. This step focuses only on papers around
digitalization within SC by associating terms such as "SC
performance", "firm results", "SC practices",
"firm efficiency". Table 1 present overall database analyzed in this paper.

database share 80,42% of their papers with Scopus database. After removing
duplicates, it remained 378 papers.
In
the fourth step, the authors restricted the search to HCERES papers ranking
published both in English and French. The final set is covered 207 articles
that appeared appropriate for structuring the research on digitalization in the
fields of business and management. The mayor criterion was to be a paper that
treats the impact of digitalization or the former technologies on the SC.
The
papers considered are those published between 2012 and January 2021 as
presented in the table 2. As the digitalization of industrial practices is not
a new phenomenon, several publications date from before 2010. In this review,
the publications prior to this date were ignored because the concept of
Industry 4.0 came into being in 2011 (Lasi et al.,
2014).

The
number of published papers around Industry 4.0 increases year after year. 2020
has the largest number of publications. This can be explained by the growing
interest of researchers to the subject. For the year 2021, only the published
papers of January were included.
Most
of journals considered have significant impact factor (from 4,8 to 28,8 see
table 3 below). After identifying the articles, we profiling them by using
database index.
Web
of Science and Scopus data bases generate files that contain all information
necessary to automatically conduct the research profiling by simply inserting
these files into the software. As the other bases do not provide such
information, we performed that task manually (de Oliveira et al., 2018).
Authors
then analyzed the abstracts and implications of
selected papers. Then the entire paper. Likewise, if the main subject, the
objectives, the methodology but not the main results were not clearly
identified, a rigorous analysis of the whole document should be carried out.
According
to table 3, Production Planning & Control is the most representative
journal of our review (50 papers) and its impact factor is high (11,1). It is
followed by International Journal of production Research (23) that’s one of the
most cited (92%) journal in management with an impact factor of 14,6. The
Supply chain Management journal is on the third place with 12 papers. Even if
its impact factor (13,4) is high than that of the most represented journal in
this study. More than 66% of papers are published in the journals that impact
factor is equal or high than 10.
The
resulting analysis allow the following review.

This
section will present the context of research, the research area, barriers for
the digital transformation and different methods used by authors within
digitalization research.
Figure 1 : technologies available
Papers
on Industry 4.0 are the most representative in a set of papers analyzed. Its followed by digitalization. Big data,
Blockchain and IoT apear as important technologies
within SC. It is however difficult to realize a clear split between the above
technologies. Individually, the concepts of digitalization and Industry 4.0 are
the most developed. If we consider that Industry 4.0 brings together Blockchain
technologies, the Internet of Things (IoT), Cloud, Big Data and Cyber-Physical
System (CPS), we will have a much higher number of published papers on the
technology. Their number would be higher than that of publications related to
IT (digitization) and digitalization which are prerequisites for the
implementation of Industry 4.0. With these available technologies within the
industry, it found remain difficult to easily identifying their real
contributions. The next section would help to clarify this issue.
Digitalization
tools are important for managing the SCs and enhancing their performance in
this dynamic environment (Jabbour et al., 2020; Gupa et al., 2020). The digitalization of SC aims to
facilitate exchanges between stakeholders. The review identified 59 articles
addressed that (see figure 2 for illustration).
The
researches presented in the figure show that digitalization aims to increase
productivity, enhance the operations management, increase the resilience of the
SC, facilitate exchanges but also lighten the management of relationships
between customers and suppliers. It participates in the improvement of quality
management practices and sustainable SC. This observation is also that of Ben-Daya et al. (2019) who find that the areas covered by
digitalization include visibility of production units, production planning, production
scheduling, quality inside and beyond the manufacturer unit, maintenance and
connectivity of supply chains. It is thus implemented in industries as well as
in the agriculture, in the health sectors or in the public administrations.
According to Verhoef et al. (2021), digital transformation follows three
distinct phases: digitization, digitalization, and digital transformation.
For Daxböck et al. (2019), organizations have already started
adopting digitalization tools for revolutionizing their SCs. For these authors,
in near future, organizations will not be able to function without digital
tools. The available applications can achieve the strategic objectives decided
by the managers, and then, based on real-time information from several Internet
sources, can propose a solution to a problem that may arise (Swanson, 2017).
Couzineau-Zegwaard (2020) found that digital solutions cover a fairly broad spectrum of
solutions that improve the company's capabilities. This in different ways:
predict demand, model and simulate its various processes, collaborate within
the company, but also with service providers, suppliers, partners and
customers, more, automate industrial and logistical processing as well as
processing related to the transmission of administrative or
Figure 2 : themes addressed within
digitalization researches
The
study conducted by Forrester Research (2008) on the implementation of
digitalization concludes that American industries are reaping the benefits of
digitalization, in particular through the reduction of cycle time, timely
delivery of products to the customers, achieving higher efficiency and
improvement in SC agility (Hennelly et al., 2020, Gupa
et al., 2020). With adoption of digitalization and IT in supply chain
management (SCM), firms can improve their performance by developing and storing
data regarding customers, suppliers and others stakeholders in the organization
(Gupa et al., 2020). By virtue of their use
potential, digitalization tools shorten the distances between business partners
and strengthen the links between the firms and its customers.
However,
this reality still seems misunderstood by many companies. This is the case of
SMEs, for example. Taiminen and Karjaluoto
(2015) question the understanding of the digitalization challenges within SMEs.
They wonder if SMEs have understood the fundamental change in the nature of
communication brought about by digitalization. Because according to them, SMEs
do not seem to use the full potential of new digital tools and therefore do not
yet take advantage of their opportunities. However, these technologies provide
SMEs the opportunity to reach interesting marketplaces while expanding their
customer portfolio (Benzidia, 2012). Thus, digital
transformation of SMEs can improves business results and increases the
productivity and output of the workforce (Hai, 2021).
The
line between digitalization and Industry 4.0 is very thin, but the difference
between the two concepts lies in the fact that digitalization, which itself
preceded by digitization, is a prerequisite for the adoption of Industry 4.0.
Therefore, what will be the contribution of Industry 4.0. to supply chain?
Papers
published on Industry 4.0 mainly present the performance resulting from its
implementation. Authors demonstrate the ease of operations within the supply
chain bringing out by the technology. They also present some success models
within the supply chain. The researchers also identifying the expectations of
managers vis-à-vis this revolution. The fields of investigation are as varied
as the number of topics covered. Industry, health, defence, SMEs, retails,
energy or even services, agriculture.
It
emerges from the literature that Industry 4.0 is defined through several concepts
such as Industrial Internet, Smart Manufacturing, Smart factory, Factory of the
future/Factories of the future, Advanced Manufacturing, Intelligent
Manufacturing, Industry of the future / High value manufacturing, Smart
Industry/SmartIndustry, Manufacturing 4.0, Integrated
industry, Digital Factory, Manufacturing Renaissance, Make in India (Kagermann et al., 2013; Falet et al.
, 2019).
According
to Blanchet (2016), Industry 4.0 is not a fad per se. It is a concept that
represents the adoption by industry of techniques and processes enabled by
digitalization, cloud computing, the Internet of Things and big data to gain
competitive advantages in national and worldwide markets (Reinhardt et al.,
2020). Each of these technologies has numerous advantages which the potential
is gradually revealed in the literature.
Figure 3 :
topics developed within Industry 4.0 papers
The
Internet of Things is one of the major enablers of SC cohesion. Ben-Daya et al. (2017) defined it as a network of physical
objects that are digitally connected to sense, monitor and interact within a
company and between the company and its supply chain enabling agility,
visibility, tracking and information sharing to facilitate timely planning,
control and coordination of the supply chain processes. Some authors like Tu
(2018) argues for the transparency that IoT brings to SCM due to the global
network of physical objects. Mainly devoted to the SC delivery processes,
transformation or even food SCs, IoT could help manage SC remotely, provide
more precise information and ensure better coordination between different
entities for effective decisions taken.
IoT
improve previous technologies in SC. As showed Tu et al., its outperforms
current barcode-based system regarding labor cost,
efficiency, and operational adaptiveness. Their potential favour exchanges
between SC members. Thus, Haddud et al. (2017)
confirm the significance impact of IoT potential benefits to individual organizations
and their entire supply chains. Its contribute to build critical success
factors for successful SCM. Cui et al. (2022) provide most important measures
of the IoT in improving SC. i.e. improving information transparency,
strengthening the integration of management information systems and improving
large data processing abilities.
Figure 4 : topics
developed in IoT papers
The
nine articles selected on IoT develop different topics: productivity, SC
sustainability and innovation or servitization. But,
by considering that some technologies like RFID or more widely IT in business,
are initial stage of IoT, 27 others papers must be considered. The figure 4
provides details for IoT specific papers.
Analysing
the impact of IoT in retail sector, De Vass et al. (2021) reveal that multiple
IoT forms provide additional capabilities in data auto-capture, visibility,
intelligence, and information sharing for greater integration of retail supply
chains. That, in turn, enhances supply chain performance in cost, quality,
delivery, and flexibility dimensions to improve firm financial, social, and
environmental sustainability. From purchasing side, IoT help to work with
dynamic and complex markets. Its also supports the
development of a more capable and efficient Purchasing and Supply Management
organisation (Legenvre et al., 2021).
Internet
of Things takes supply chain communications to another level: the possibility
of human to things communication and autonomous coordination among ‘things’
while being stored in a facility or being transported between different supply
chain entities (Ben-Daya et al., 2017). This
technology will allow the reduction in the time between data capture and
decision-making that enables supply chains to react to changes in real time
allowing levels of agility and responsiveness never experienced before (Ben-Daya et al., 2017, Ellis et al., 2015). With these
possibilities, IoT provides more capabilities to react when risks arise.
Prim
et al. (2021), present the IoT and Big Data as tools for real-time monitoring
of supply chain processes, supporting proactive decision-making, reducing
operational costs and improving product quality. They also claim that a
collaborative partnership would reduce the learning curve and barriers to
adoption, and increase the likelihood of successful implementation. Blockchain
bring more security to the above collaborative partnership.
Blockchain
is considered as a distributed database of common public/private records or
ledgers of all digital transactions that have been executed and shared between
agents participating in the chain (Benhayoun et Saikouk, 2022 ;Saberi et al.,
2019). Though Blockchain Technology (BT)–SCM integration is still in its
infancy (Queiroz et al., 2020), from Swan (2015) perspective, its enables
timely and more efficient business relationships. It mitigates risks and
reduces transaction costs. It overcomes currency fluctuations and speculation
between shipper and importers as well as other stakeholders. It verifies the
origin of a product by providing information on time, place and manufacturers,
and offers information on its journey from suppliers to consumers (Lesueur-Cazé et al., 2022; Benhayoun
et Saikouk, 2022). Decentralization bringing out by
Blockchains promotes security as it makes less likely to crash, be corrupted or
hacked (Benhayoun and Saikouk,
2022; Tian, 2016). The double spending and double-booking problems can also be
easily solved by the blockchain as there will only be one transaction related
to the previous and ongoing block in the chain that can be approved.
There
are other technologies such as Direct Digital Manufacturing (DDM), Cloud, Big
Data or Cyber-physical systems and they contribute to improve products or
improve their ability to meet customer demand. For example, in food industry,
Ali et al. (2021) noted that the main drivers for the adoption of Industry 4.0
technologies are cost optimization, food safety concern, facilitation of
regulatory compliance and the ability to better match supply and demand.
The
above figure 5 present topics addressed by Blockchain technology.
Most
of papers deal with BT adoption, its importance in SC efficiency or SC
sustainability in developed and emerging economies. Economies in which there are differences in
the variables that determine the BTs as well as their stage of diffusion (Wamba
and Queiroz, 2022).
Figure 5 :
topics developed in blockchain papers
Foremost,
while Queiroz et al. (2021) pointed out that, the most critical constructs that
directly affect BT adoption in emerging economy are facilitating conditions,
trust, social influence, and effort expectancy, Kamble
et al. (2019) found that the technology readiness index constructs-Insecurity
and discomfort have an insignificant effect on the perceived ease of use and
usefulness. For these authors, perceived usefulness, attitude, and perceived
behavioural control affect the behavioural intention. They found that,
subjective norm has a negligible impact on behavioural intention. Finally, Wong et al. (2020) revealed that
facilitating condition, technology readiness and technology affinity have a
positive influence on intention to use BT in SC and regulatory support
moderates the effect of Facilitating Condition.
While
most of papers on BT seek to understand its importance in SC, others provide
insight for its implementation within SC operations as well as in SC
sustainability. For Wang et al. (2019), the value of such technologies for
supply chain management lies in four areas: extended visibility and
traceability, supply chain digitalization and disintermediation, improved data
security and smart contracts.
Widely,
blockchain could transform practice, including enhancing product safety and
security, improving quality management, reducing illegal counterfeiting,
improving sustainable supply chain management, advancing inventory management
and replenishment, reducing the need for intermediaries, impacting new product
design and development, and reducing the cost of supply chain transactions
(Cole et al., 2019). The above efforts are more-oriented toward improving
operational-level capabilities (information sharing and coordination
capabilities) than strategic-level capabilities (integration and collaboration
capabilities) within SC (Nandi et al., 2020).
According
to the first group of authors, implementing Blockchain helps to fulfilling SC
goals of performance. Therefore, dealing with inefficiency within SC operations
Xue et al. (2021) find that blockchain is a helpful
tool to realize the goal of SC management to reduce cost, improve quality and
enhance the overall efficiency of the system. Blockchain improves the
efficiency of the process: it reduces the number of operations, reduces the
average time of orders in the system, reduces workload, shows traceability of
orders and improves visibility to various supply chain participants (Rogerson
et Parry, 2020; Martinez et al., 2019, Wang et al., 2019). Blockchain
technology (BT) increases the operational transparency of the Supply Chain and
the trust that is built between members of the Supply Chain, which improves
coordination (Dubey et al., 2020). BT largely contributes to the improvement of
demand forecasting in SCs (Benhayoun et Saikouk, 2022).
For Azzi et al. (2019), the BT is introduced to achieve the
supply chain’s objectives, by reducing the risk emerging from the tracking
system and data management. More, competitive performance is directly improved
through blockchain adoption and also indirectly through blockchain-enabled
process and relational innovation (Fosso Wamba and Guthrie, 2020). Kayikci
et al. (2022) admitted that BT resolving major challenges, such as
traceability, trust, and accountability in the food industry.
The
second group is focus on circular economy. Though BT adoption to boost circular
economy has been mostly at the demonstration and piloting stage (Kouhizadeh et al., 2020; Wang et al., 2019), Nandi et al.
(2021) show significant patterns on adoption levels of the BT-enabled circular
economy system (BCES) and localization, agility and digitization (L-A-D) capability
development. For these authors, the greater the BCES adoption capabilities, the
greater the L-A-D capabilities.
For
example, even Blockchain promotes cooperation between the main players in the
aviation industry and the air traffic controllers to reduce fragmentation,
inefficiency, and uncoordinated operations, or allows information and data
sharing, Di Vaio and Varriale
(2020) show that Blockchain it is still not possible to observe a high level of
sustainable performance.
Authors
use different methods to address the impact of digitalization on SC as
presented in the section below.
These
researches are developed within several sectors. The most representative is
manufacturing industry (fashion, agribusiness, automotive, energy, …), service
industry (transport, logistic, tourism retailing, …), Healthcare…
Quantitative
methods are the most representative in research on digitalization over the
period studied (36,36%) followed by Qualitative methods (35,40%). Conceptual
researches represent about 24%. This result may explain the maturation path
followed by research on digitalization. The table below provides details of

Even
if the importance of technology is highlighted in the SC, the remain many
reasons that prevent managers to adopt it. Section 3.4 presents some of them.
There
are numerous barriers on the adoption of digitalization and Industry 4.0. This
can overall be attributed to the stigmas left by previous technologies (ERP for
example), ignorance or fear of the unknown among some managers and their
perceived adoption costs (Papathanasiou et al.,
2020).
Lack
of transparency in information is one of most important barrier. As pointed out
Derrouiche (2022), information integrity, transparency, and security are
necessary requirements for Supply Chain 4.0 applications, especially when there
are several stakeholders sharing and processing sensitive data. Lesueur-Cazé et al. (2022) pointed out the governance
issues as the mayor difficulty in Blockchain adoption within SC.
For
some authors, the non-adoption of Industry 4.0 isofar
attributed to the reluctance of some stakeholders, or due to the lack of
standard architecture, to Internet access difficulties, contractual problems,
confidentiality and security issues and the underdevelopment issue (Chauhan et
al., 2021; Kamble et al., 2019). For example, in the
electronic marketplace, Benzidia (2014) found that,
the mayor challenge remains the security and technological reliability issue
for succeed in reverse auction. But there is also the matter of organizational
culture, process re-engineering and staff resistance to change that can hinder
the implementation of technology (Derrouiche, 2022). More, it can be the matter
of organizational inertia, financial constraints or lack of resources sharing
within the food supply chain (Ali et al., 2021).
For
others, factors such as : "no sense of urgency", lack of industry
specific guidelines, lack of digital skills and talents (Nguyen et al., 2015),
lack of an overall digitalization strategy and competing priorities (Kane et
al., 2015), lack of understanding and lack of top management commitment; lack
of support and absence of government policies; and poor level of research and
development, high implementation and running costs; fear of failure;
compatibility issues are the main obstacles to the adoption of Industry 4.0
(Agrawal et al., 2019; Majumdar et al., 2020). In the SMEs sector, Stentoft et al. (2020) found that it is the lack of
managers perception of Industry 4.0, and not their perception of the high
barriers of Industry 4.0, that hinders the SME development readiness for
technology. Finally, for Haddud et al. (2017), IoT
challenges are still perceived as major obstacles to their adoption.
From
the above developments, many implications can be drawn. Section 4 highlights some.
According
to Papathanasiou et al. (2020), ERP transformations
have left organisations fatigued and disinclined towards further systems
development and resistant to subsequent change. Yet they are well aware of the
positive contributions of technologies such as blockchain on business
practices. This therefore implies for managers to first and foremost carry out
a check-up of the company's current technology state before embarking on a new
one that would overlap the existing without, however, providing any real
perceived value.
For
Chauhan et al. (2021), intrinsic barriers (vs extrinsic) are more important and
relevant for the adoption of Industry 4.0. This assume that if we fail in
specifying the objectives of digitalization and in the clarifying process of its
potential benefits and costs, it will be difficult to remove reluctances and
take advantage of its prowess. Like these authors, and with the accordance of
the resource-based view theory, we urge managers to take into account the
availability of both material and human resources. They will better do this by
preparing the different stakeholders both through training and communication.
In
addition, industries in developing economies are still struggling to embrace
Industry 4.0. The actors are specifically interested in technologies that allow
them to strengthen their productivity in order to ensure their economies of
scale and therefore reduce costs to offer a price matching the customers
income. While, the implementation of technologies such as blockchain or IoT
would stimulate trust between partners and speed up the innovation process,
which are another source of competitiveness.
Although
represented in the papers analyzed, the
implementation of Industry 4.0 in retail chains does not interest researchers
as much as the upstream part of the chain or the firm internal process
management. Yet Piroth et al. (2020) find that
logistics issues and technological infrastructure are viewed as key drivers of
online grocery retailing. Retail chains should therefore take greater ownership
of these technologies to improve their services.
This
research aimed to analyze the papers dealing with the
impacts of digitalization and mainly of Industry 4.0, Blockchain and IoT on the
supply chain. It emerges that it is a new subject which is arousing more and
more the researchers’ interest in observing the ever-increasing number of
publications. The impacts observed are numerous and cover a wide spectrum of
themes specific to various types of industries and environments. Some barriers
are presented, but also some implications aimed at drawing attention both to vigilance
in choice of technology, but also to the unavoidable nature of this new
industrial revolution for the supply chain.
The
attempt to splitting the themes or technologies analyzed,
which is certainly interesting for understanding the research directions,
remains poorly realistic. For example, it is difficult to be able to clearly
distinguish between articles dealing with digitalization from those dealing with Industry 4.0. Future researches
must consider this. The choice made on the HCERES journals repository restricts
the scope of the literature review analysis initiated. We plan to expand this
field in our future research.
