ABSTRACT
In today's supply chain, information sharing and accountability for
goods is critical, accordingly to the principles of fiscal, environmental and
social security, which have been also concentrating on in recent years,
prioritize business process openness. The economic consequences of the COVID-19
outbreak and prevention strategies incorporate factors such as supply and demand
shocks as a result of COVID-19. This paper investigates the sensitivity of the
supply chain to the unfolding pandemic crisis by identifying the five main
barriers for Indian manufacturing industries in the new COVID-19 time by employing a hierarchical approach, based on multi-criteria
analysis. A hierarchical process-based multi-criteria approach has been used to
evaluate COVID-19 influence and prioritized by Entropy and TOPSIS technique.
The findings shows that local law enforcement obtained the highest weights
among all the supply chain barriers operations in the COVID-19 time, and among
the industries, airline, hotel, and automobile sectors have been most affected
by the global crisis. The obtained findings will
provide the strategic outputs for decision-makers to strengthen the supply
chain following COVID-19 protocols.

INTRODUCTION
As
the COVID-19 triggers worldwide economic
turbulence, contemporary supply chains facing new types of difficulties in the
managing the logistic. In order to define minimum lead times at a cheaper
price, today the globalized supply chain network is looking for optimization.
Nevertheless, swift political changes, a move to customers purchase specialty
goods and global pandemics have exposed the flaw at the core of this paradigm.
Manufacturing nowadays, in contrast with only a few decades earlier, is much more
complicated than that of a sub-component that has to assemble a single element
from many locations all over the world. The raw materials used to make these
parts may also be imported from many areas of the globe, and the final products
will then need to be shipped all over the world. This huge logistics dependence
makes buying, processing and shipping a complicated proposition when supply
chains are disrupted.
The supply problem for the
manufacturing company falls on the opposite side of the coin. The growing
consolidation of the output at low cost, especially in China, Taiwan, and
Vietnam and other low-cost economies, has been motivated by a drive towards
productivity in a globally interconnected environment. The pandemic that has
started in China has now reached other countries world-wide and the consequent
consequences and vulnerabilities have shown an increasing need for risk in
distribution more than ever.
The holding of vital
commodities/stocking of non-commercial products on the customer side resulted
in unusual pressure in the supply chains. Panic on food and other main items
during d times is not an uncommon occurrence for consumers. Since this adds to stress if the stockpile
goes past several weeks, customers are naturally worried about supply and
recourse to such behaviors. These unnatural demand swings and essential supply
volatility are incredibly difficult to manage and produce a bullwhip effect in
the whole supply chain and sometimes results in an artificial shortage.

First
and foremost, our study is closely related to research investigating the
impacts on commodity demand and availability of natural hazards such as
geological incidents, earthquakes and snowfalls (Cavallo, Cavallo & Rigobon 2014). According to WHO (2020) reports that the
world's supply chain poses an immense challenge in preserving smooth food
sources and medical devices such as masks and medicines that are very important
to manage, secure and monitor the pandemic.
Carvalho
et al. (2016) illustrated in the context of supply chain disturbances following
the Great East Japan earthquake the role of input and output links using
company-level data. Mahajan and Tomar (2020) looked
at disruptions in food supply chains as a result of the COVID-19 economic
shutdown in India and found that supply networks for long distances were most
seriously affected during the latest pandemic, with social gains for cities and
farmers.
The international pandemic prevention policies have blocked
the movement of finished products and raw materials from manufacturers into
many parts of the world. Wuhan, the
COVID-19 epicentre for example, is a cluster of car
factories with foreign marks like General Motors, Hyundai, and Toyota, among
others (Yu & Aviso, 2020). The five
major supply chain hurdles, including lack of personnel, the local
implementation of regulations, lack of traffic, shortened of raw
materials, and cash flow deficits, were studied by Biswas and Das (2020).
Information
sharing is recognised as a significant source of
competitive advantage, and hence the interest of academics and practitioners to
understand and isolate certain factors which contribute to the successful
transfer of knowledge between supply chain actors during the pandemic has been
increased (He, Ghobadin, & Gallear,
2013). The creation of SC based on knowledge
depends on the essence of the knowledge flow in the whole chain. It would be
very helpful for SC collaborators to exchange decision-making details in due
course. Although administration and business culture are the biggest hurdles
(Shih, Hsu, Zhu, & Balasubramanian, 2012).
A
further challenge to the supply chain is that businesses should identify
specific strategies and procedures that are planned and shared to all
stakeholders to efficiently handle logistics activities (Badenhorst,
2016). In addition, businesses need to combine both the reverse and forward
logistics to handle goods, money flows and knowledge and improve a reliable and
efficient supply chain for an integrated loop (Prakash & Barua, 2015).
Agrawal et al. (2020) analyzed the impact of COVID-19 on Indian supply chain
and economy and identified 18 main obstacles affecting supply chain operations
in India.
Despite an important proportion of
Indian importers across a wide variety of industries, frequent trips to Chinese
processing hubs have been used to position orders for goods. These visits are
now postponed or scrapped off and importers worry that they will lose as things
stabilize and importers from other countries fight to get their own orders. The
move from production to trading and over reliance on the Chinese inputs led to
the closing of several firms in India.
After COVID-19, the planet must
shift to the new standard. This current normal would take a new look at the
globalization framework. The critical mass of value chains developed into China
is absolutely decimated by COVID-19. Experts warn that vast numbers of
producers are having problems of supply as a result of the outbreak, as
businesses expand the use of unforeseen circumstances' a contract rule relating
to exceptional circumstances that prohibit or impede the fulfilment of their
obligations.
Companies across the globe are
trying to diversify their procurement policy, with India benefiting from this
step that cracks the focus supply chain mound into effective and efficient
supply chain mounding. After COVID-19 led deconstruction, India is bound to
prosper from this re-structure supply chain surge. The survey result from
online sources has been gathered to accomplish this paper and 100 manufacturing
experts have been asked to fill the questionnaire using purposive sampling.
The online mailing, telephonic
interviews, and two follow-ups fetch 87 usable responses. The time period of
data collection was Oct – Nov 2020. A questionnaire was developed to collect
the data from the academicians (who are teaching operations in various
institutions, colleges and universities) and industry experts. The layout of
the questionnaire was as follows:
(1) Introduction to supply chain and
COVID-19 impact
(2) Description of supply chain
barriers
(3) Guidelines on how to fill in the
questionnaire tables
(4) Pairwise comparison matrix of
the factors.
Since,
the objective of the paper is to identify supply chain barriers and their
impact on different Indian industries during the COVID-19 times. Therefore,
this paper investigates the sensitivity of the supply chain to the unfolding
pandemic crisis by identifying the five main barriers for Indian manufacturing
industries in the new COVID-19 time by employing a hierarchical approach, based
on multi-criteria analysis, i.e.,
Entropy and The Technique for Order of Preference by Similarity to Ideal
Solution (TOPSIS) approaches. The paper is organized in five sections. Section
2 discusses research methodology for study and covers both Entropy and TOPSIS method. Section 3 covers application of the
proposed work. And, section 5 concludes the study, and discusses implications
of the study.

METHODOLOGY PROCEDURES
Though several studies have been
conducted on obstacle difficulties in the supply chain, no research has been
conducted during COVID-19 assessment and classification of these deficiencies.
This study aimed to rank the barriers encountered in supply chain due to
COVID-19 by importance of degrees, using the integrated Entropy and TOPSIS
approaches. Classification of the barriers encountered in supply chain due to
COVID-19 is shown in Figure 1, and have been identified after several rounds of
brainstorming and discussion.
The second aim of this study is to
prioritize attribute and sub-attributes that can be used for the evaluation of
the different economic sectors of India.
Integration of Entropy and TOPSIS (Salehi et al. 2020; Liu et al. 2019; Wang et al.
2007) approaches are evidently used in numerous applications of real life
study. These approaches are chosen because they offer straightforward solutions
for difficult decision-making problems and produce precise and efficient
outcomes. However, no research has been done on the challenges to newly
developed studies focused on COVID-19 effect on supply chain systems.
The primary objective is to
recognize the barriers and prioritize them, and their effect on manufacturing
industries during COVID-19. The Entopy and TOPSIS
have been chosen as the most suitable form for determining the impact of
COVID-19 on supply chain and supply chain performance in different
manufacturing industries. The data analysis part was divided into two sections.
The first section comprised of application of Entropy to assign weights to
various attributes (section 2.1).
The second section involved application
of TOPSIS to assign ranks to different attributes as per closeness index value
(section 2.2). In the current study, Entropy is used to calculate the
weightages, which will serve as a primary input to TOPSIS analysis. The steps
of the methodology we apply is given below:
2.1.
Determination of Weight
The Entropy weight approach from
thermodynamics to information systems was initially implemented (Shannon,
2001). In communication systems, the vagueness of signals is called
"information entropy". The smaller the entropy, the larger the
weight. Assume m alternatives are
available for the evaluation of n assessment requirements, let is
the initial assessment value of the decision matrix. The Entropy weight
approach for determining the rank of the attributes is described below:
Step i) The decision matrix is standardized
as follows:
, i=1,2,3,…,m and j=1,2,3,…,n (1)
Where is
the normalization value of the decision matrix.
Step ii) The information entropy for each index is
defined as:
And the information entropy for each
index is defined as:
(2)
Where .
Here is the weight attached with each of the
attributes.
2.2.
Determination of Criteria and
Attributes
TOPSIS procedure (Hwang et al.,
1993; Dwiedi et al., 2018) for determining the rank
of the attributes is described below:
Step i) Use the equation (3) to construct
the normalized decision matrix
, i=1,2,3,…,m and j=1,2,3,…,n (3)
Step ii) Calculate the weighted normalized decision
matrix ()
after obtaining the normalized matrix, by using equation (4)
* (4)
Step iii) Determine the ideal solution of
each of the attributes i.e,
assume that be
the positive ideal solution of the attribute’s and be the negative ideal solution of the
attribute’s.
(5)
(6)
Where,
and have a favourable
and detrimental effect correlated with the attribute’s.
Step iv) Compute the equidistant measure from each of
the positive and negative ideal solutions, i.e.,
Use
the equation (6) to determine the equidistant of each alternative from the
positive ideal solution:
(7)
Use the equation (8) to determine
the equidistant of each alternative from the negative ideal solution:
(8)
Step v) Use the equation (9) to determine
relative proximity to the ideal solution and rank them.
, (9)
Note that, the higher the relative
proximity value, the higher the rating order and hence the better the
alternative results.

APPLICATION OF THE PROPOSED
FRAMEWORK
The supply chains are in the global
spotlight while the world is confronting the human and economic crises and pose
complex problems. This year's COVID-19 pandemic has triggered unparalleled
global health and economic distress worldwide. Several countries have
implemented and continue to impose comprehensive lockdowns to reduce the quick
spread of infection across their population.
This has contributed to major global
disturbances in demand and supply. When the pandemic crisis deepened and
nations started lockdowns, supply chains encountered something totally new:
Structural bursts in demand, where individuals stock in commodity staples to meet
with mass deportations, often purchase months' worth of merchandise in one day.
Naturally, this lockdown presented major obstacles to industries that supply
'relevant' products and services, such as the healthcare industry.
The fast reaction from internal
departments, business bodies, and policymakers has helped those businesses
mitigate disruption. The supply chains are broken or seriously affected with
widespread disturbances. The supply chains in India will be experiencing major
transitions in the near future as the effect on production and consumption
systems continues to threaten due to COVID-19. As existing problems on the
supply side continue to be resolved, demand will decrease in some sectors of
industry, causing more disturbance. Organizations should react to this current
reality and learn about creating supply chain sustainability in certain ways.
Disruptions in terms of the size and
magnitude of supply chain is unparalleled and are further compounded by the
multinational existence of the underlying supply chain. The present situation
has really brought to the fore the interconnectedness and interdependence that
happens in all facets of our lives, but this has been experienced more than in
the global marketplace in no other respect. In addition, a supply chain has to
be implemented seamlessly with many separate elements and a large human
workforce that supports and facilitates it.
The COVID-19 pandemic exposed the
vulnerabilities of those supply chains and highlighted the importance of supply
chains to the public and to the world economy. As the Indian lockdown began,
demand for vital goods forced some organizations to scramble for supplies and
raw materials, while other organizations saw their demand totally stagnated or
deteriorated.
After reviewing the literature, we have identified number of barriers
occurring in the supply chain during the COVID-19 times, it includes, lack of
man-power (Prakash & Barua, 2015; Katiyar et al.
2018; Mahajan & Tomar, 2020; Biswas & Das,
2020;), local laws enforcement (Badenhorst 2016; Kaur
et al., 2018; Biswas & Das, 2020), lack of transportation (Khurana et al.
2011; Mahajan & Tomar, 2020; Biswas & Das,
2020), scarcity of raw materials (Cavallo et al., 2014; Kaur et al., 2018;
Biswas & Das, 2020 ), and deficiency in cash flow in the market (Parkan & Dubey, 2009; Prakash & Barua, 2015;
Cavallo et al., 2016; Biswas & Das, 2020). Classification of the barriers
encountered in supply chain due to COVID-19 is shown in Figure 2 along with
industries.
Figure 2: Supply Chain Barriers
During the 21-day cycle of locking,
the ongoing unavailability of employees affects the most important supply chain
of industries. Despite being one of the key resources and enabling production
to continue, a lot of manufacturing plants fail to operate their capacities
because the number of employees is not sufficient. At present and even after
COVID-19, the lack of labor, since most jobs in the manufacturing hubs
relocate, is clearly a big concern. This heat map of trucking movements in the
country shows very simply the effect of COVID-19 on the logistics business.
Although transport is the cornerstone
of logistics, the industry acts as a hub for other main business sectors, such
as material processing, storage, packaging, shipping protection, warehouse
control, supply chain administration, acquisition and customs services. While
the Center has kept the country's key ports and airports open for freight
transport despite a current crisis, restricted evacuation of the imported raw
material to factories would create production barriers for FMCG firms.
Owing to the small potential of both
sea and air freight ports in India, businesses face a shortage of imports of
goods that are exceedingly difficult to find for a domestically manufactured
substitute. In these tough times businesses are collaborating together with the
government and local authorities to make sure that our nation's peoples enjoy
consistent and uninterrupted distribution of critical products.
The disruption from COVID-19 is not limited to select market pockets,
but is a prevalent disease that is likely to keep the economy sick for long
indefinitely. Although the severity of the effect will vary from industry to
industry, some industries have suffered more and are still suffering. The
impact of COVID-19 on the following industries, Power Industry, Consumer and
Retail Industry, Chemical Industry, Construction and Retail Industry, Freight and Logistics, Metals and Mining,
Textile Industry, Oil and Gas Industry, Automobile Industry, Airlines and
Hotels have been observed.

Table 1 shows
descriptive statistics of the considered barrirers in supply chain during
COVID-19. Among them, the mean value of Local laws enforcement and scarcity of
raw-materials is found to be higher than all the considered barriers. The
hierarchical structure of the case under consideration were characterized by
various number of barriers and affected industries, as seen in Figure 1.
According to the obtained survey result, the criteria and attributes with
highest total rank have been used to form the hierarchy table to evaluate the
barriers of supply chain and their impact due to COVID-19 on the different
industries of India.
A total of five major criteria’s were chosen for
estimating the COVID-19 impact on ten
industuries of India. The main criteria of barriers of supply chain have been
evaluated pair-wise and comparison matrix has been built and their weights determined
by using the Entropy method is been given in Table 2.

Centered on lessons that are
improved and tested in the ongoing economic crisis, organizations will build
robust supply chains in the post-COVID environment in a number of ways.
Firstly, it is urgent that physical labour is minimized across shipping,
procurement and processing. This can be achieved by using crucial emerging
technology such as Internet-of-things, block-chains, controls, quantum
computing learning for the estimation of production, regulatory and
self-adjusting inventories, individual robots like AGVs, drones, among others.
The
standard would be factories capable of modularizing manufacturing and
shifting/adapting lines in view of changing demand. They would be assisted by
supply networks that would constructively connect with each other and make
their productivity and agility better. Enterprises will concentrate much on
delivering essential systems on the cloud that enable staff to access them
remotely when operating at home.
We
will need to see more of the cloud migrants taking the last leap to the other
hand and eventually switch into the cloud to allow business processes. Protection will also be a crucial aspect and
the risk control of suppliers will be central to all the strategy efforts. One
of the few promising facets of COVID-19 has opened us to the possibility of remote
working through markets, sectors and enterprises, and this development will
lead to a renewed emphasis on the ideals of environmentally sustainable
activities as it is preserved in the post COVID world.
In
conclusion, our capacity to learn from our accumulated experiences and to apply
these learning strategies more powerfully than any other sentient mode of life.
In exclusively commercial words, COVID-19 poses a range of significant
obstacles, often unparalleled, to companies, including a potential cash crisis,
worldwide supply chain interruptions, increased trade barriers and changing
customer preferences. However, emerging technology will play a vital role in
developing companies in the post-COVID era, including more resilient supply
chains, better customer interface, and intelligently optimized systems to
achieve market performance.

CONCLUSION
The instability of dynamic global
supply chains based on lean production theory has been established by COVID-19.
This is especially true in the healthcare sector where the scramble for
protective gear has demonstrated that inventory and single supplier versions
are exposed primarily to the risks associated with cost management. The effects
of the lockdown of China and its domination in main production areas have
further exposed the issue with supply chain management. When the Chinese and
other factories in developed countries were shutdown down to COVID-19 pandemic,
global suppliers were unable to swing because the supply base was lacking in
versatility.
One potential outcome is that
multinational companies will in the future diversify supply chains, rather than
depending exclusively on China and other developed countries. New manufacturing
hubs such as Vietnam, Mexico and India would possibly benefit from this move. A
swift, full-scale digitization of the paperwork accompanying global trading
would underpin the transformation into a modern paradigm of supply chains.
The ties between buyers and suppliers remain largely paper dependent,
despite quick advancements in technology. Digitizing the interaction between
customer and seller is a crucial factor in creating robust supply chains and
far less time intensive to find and hire new vendors. Supply chains will easily
migrate to substitute vendors using technology, such as machine learning and
the internet of things, if suppliers are constantly interrupted. The current
crisis is a chance to re-establish a structure that relies on redundant
processes. The construction of smart and scalable supply lines is a key to creating
a global network to handle potential storms.
