Gravitating toward supply chain 4.0

Abstract The present study inspects correlations among different industries’ intention to tackle supply chain recovery challenges, and the correlations among diverse industries’ desire to use supply chain 4.0 technologies. Primary data for the study have been accumulated through a structured questionnaire to elicit responses from supply chain managers and executives. To examine the obtained data, descriptive statistics, Cronbach alpha, exploratory factor analysis, and Kruskal–Wallis test were used. There is no significant relation among different industries’ intention to tackle supply chain recovery challenges and to adopt industry 4.0 technologies. However, the Food and Beverage industry showed the highest level of intention to both tackle the impact of supply chain disruption, and adopt industry 4.0 technologies to ensure more resilient supply chain post Covid-19. This study is the very first attempt to identify the intention of different industries to adopt supply chain 4.0 technologies to combat challenges stem from the supply chain disruptions caused by COVID-19.

This study will pave the way for policy makers to redefine strategies for sustainable supply chain practices in different fields in post Covid-19 era.

Introduction
The COVID-19 pandemic outbreaks were the most severe supply-chain disruptions in recent history. In contrast, different industry sectors have strongly been challenged to avoid economic disruptions in their regular flows (Belhadi et al., 2021), arising from changes in disruption networks, raw material scarcity, production and transportation disruption, and social distancing . After experiencing a severe pandemic, the business world falls into a long term economic recession and pressure from the buyer to reduce delivery lead time, make advance payments and shorten the processing time (Cai & Luo, 2020;Caballero-Mashud et al., 2021;Caballero-Morales, 2021;Moosavi and Hosseini, 2021), excessive increase the price of raw materials, matching the unparalleled demand for daily products. Hence, they are telling about a solution by minimizing cost and maximizing production capacity may lessen the massive gap between customer panic demand and supply (Rahman et al., 2021), which causes winding up many companies, an increase in debt burden, prices of raw materials, shortage of labor supply and so on.
Different industries face different issues, whereas the manufacturing industry has been facing several supply chain disruptions such as suddenly high demand for the essential commodity, shortage of raw materials supply, production capacity, and so on (Hayat et al., 2021;, the energy industry has been impacted differently (variations in energy consumption and demand, extra energy demand) by this COVID-19 outbreak (Jiang et al., 2021). Safa et al. (2021) found that identifying supply chain risk and preparedness and adopting practices may reduce supply chain risk and enhance recovery during uncertain future outbreaks.
Various studies (e.g., Morgan et al., 2021) recommended several measures to overcome this situation by developing the proper plan, policies and strategies, and government support; for example, A.  indicated adopting Industry 4.0 economic sectors can reduce the impact of COVID-19. For instance, Internet of Things is one of the essential technologies for promoting a real cyber-physical supply chain, which uses sensors, actuators, and other systems . When IoT is combined with other technologies like cloud computing, artificial intelligence, and Robotics Supply chain operations can be selfexecuted and managed Harris et al., 2015; By allowing for increased proactiveness, and flexibility (G F. Fatorachian & Kazemi, 2021), enabling high responsiveness at the operations level (Oberg & Graham, 2016), allowing automated systems by linking intelligent devices, processes, and industrial operations and connecting them to the Internet Li et al., 2016;, resulting in better supply chain operations (G F. .
Other related works have been found regarding the supply chain challenges in different industries and industry 4.0 technologies that significantly impact the supply chain. Many have identified the problems of global supply chain disruptions in supply chain practices in Bangladesh (Mashud et al., 2021;Rahman et al., 2021). Many have recommended emerging technologies of industry 4.0 that can significantly impact on different industries to address challenges in pandemic (Belhadi et al., 2021;Hogan, Grant, Kelly, O'Hare et al., 2021a;. G F.  said that applying theoretical aspects to actual practice to collaborate supply chain with the supply chain 4.0 technologies to develop the performance of supply chain processes could achieve more resilience and responsiveness.
Here, the current research is the very early effort to evaluate the priority variance of different industries namely R.M.Gs, Pharmaceuticals, Food and Beverage, Manufacturing, and Service industries' intention to deal with the supply chain recovery challenges and make a ranking among their intentions. Moreover, the study endeavored to assess and rank the mentioned industries' intention to adopt supply 4.0 in their supply chain practices to address the challenges faced during pandemic.
This article tried to focus on: • To pursue the variations among different industries' intentions to tackle supply chain recovery challenges • To inspect the correlations among diverse industries' desire to use supply chain 4.0 To pursue the study objectives, following hypotheses have been developed:

H1:
There are no significant relations among the varied industries' intention to get oversupply chain recovery challenges.

H2:
There are no significant relations among the varied industries' desire to implement supply chain 4.0.
The remainder of this paper is organized as follows: section 2 presents an overview of related works, section 3 explains the methodology, while section 4 articulates the experimental analyses and results. Finally, section 5 elucidates the discussion about findings and section 6 deals with the concluding remarks.

Supply chain challenges during COVID-19
Supply chain refers to a global network used to deliver products and services from raw materials to end consumer. It works as a chronological process starting with collecting of raw materials, transportation, manufacturing, packaging and finally offering to consumers for consumption. The COVID-19 pandemic has acutely affected the world in terms of global health issues and the business world as well. The COVID-19 pandemic outbreaks are the most severe supply-chain disruptions in recent history and are likely to affect supply chains worldwide (Belhadi et al., 2021). Husen and Nusrat (2021) found that "Increase in the prices of Raw materials" is the most prominent concern of the experts in all industries that implies the most crucial recovery challenge due to the impacts of the COVID-19 pandemic in different industries.
The COVID-19 Pandemic has exposed a global economic recession which led to the frailty of supply chain disruptions.Mainly the supply chain challenges have raised due to disrupted networks, raw material scarcity, production and transportation disruption, and social distancing (Mashud et al., 2021;Paul et al., 2021). In addition to this, supply chain disruptions caused an excessive increase in the price of raw materials, and manufacturers could not adjust the unparalleled demand for daily products. Eventually, it increased the bankruptcy of several business organizations and supply chain partners (Caballero-Morales, 2021;Cai & Luo, 2020). Hence, they are talking about a solution by minimizing cost and maximizing production capacity to lessen the huge gap between customer panic demand and supply (Rahman et al., 2021;Morgan et al., 2021).
Several industries have faced supply chain challenges throughout the pandemic period worldwide. Such as R.M.Gs, Pharmaceuticals, Food and Beverage, Manufacturing and Service sectors .
R.M.Gs industry has been one of the most economically contributed and fastest growing sectors in Bangladesh (Rumi et al., 2021). China is the largest R.M.Gs exporter, followed by Bangladesh. Wuhan was the first city of China affected by COVID-19 and went to lockdown, which causes a huge disruption of raw materials supply of R.M.Gs products. Kabir et al. (2021) and Sudan and andTaggar (2021) have highlighted several issues that may occur due to the pandemic, including serious interruptions in transport and logistics services and a more significant influence on logistics and transport data, long delays, and cargo rejections.
China and India are the potential sources of providing drugs and medical equipment elsewhere in the world. The pharma sector has faced supply chain challenges due to breakdown of transportation capacity, quarantined team, labor scarcity, order cancellation due to lockdown and regulations given by countries (Modgil & Sharma, 2017).
At the same time, the supply chain of the food and beverage industry has also impacted by the COVID-19 in several ways. Due to lockdown and restrictions on movement all around the world, which caused scarcity of labor for production, harvesting, transporting etc. Moreover, customers also had preference on takeaway and home delivery rather went to restaurants (Talukder et al., 2021). Paul and Chowdhury (2020) and Hayat et al. (2021) have stated that the manufacturing industry has been facing several supply chain disruptions such as sudden high demand for an essential commodity, supply paucity of raw materials, production capacity, and so on, and advised a recovery model of revised production plan to mitigate the dual disruptions due to Pandemic. Belhadi et al. (2021); A.  and Jiang et al. (2021) have studied the impacts of the Covid-19 Pandemic on the automobile industry, energy industry, airline industry and recommended suggestions on how to lessen the risk by developing localized supply sources and adopting industry 4.0 technologies for a short and long-term basis.
Finally, to overcome the global supply chain challenges, several strategies are developed by strengthening organization structure, obduracy to cope with any uncertain crises throughout the supply chain, restoring, additional investment, and technologies for digitizing inter-related processes, adopting new strategies, policies, and much more (Ivanov, 2021;Ellram et al., 2020;Sarkis, 2020;Ivanov, 2020;Farooq et al., 2021).

Supply chain 4.0 and industry 4.0
Supply chain 4.0 refers to applying and using industry 4.0 technologies in the supply chain context (Weber and Weber, 2010;Dossou, 2018;Frederico et al., 2019). Makris et al. (2019) defined supply Chain 4.0 as a supply chain containing a solid association of multiple partners, such as suppliers and customers, developed on disruptive technologies like web-enabled technology, cloud computing, and the Internet of Things. According to the German Federal Ministry for Economic Affairs and Energy and Standardization Administration of the P.R.C., 2018, industry 4.0 incorporates manufacturing sources, such as Instruments, sensors, and robotics, information dissemination, forecasting and managing automatically, and products and business models. Industry 4.0 is a high-tech approach that symbolizes the fourth industrial revolution, after mechanization, electrification, and computerization .
Industry 4.0ʹs technologies must be implemented in the supply chain to ensure improved performance in the market Porter & Heppelmann, 2014). Disruptive technologies aim to exceed the performance of supply chain operations and, as a result, develop better strategic outcomes . The emerging technologies play a pivotal role in the coming revolution of supply chains (Muthusami & Srinivsan, 2018;Stevens & Johnson, 2016;Tjahjono et al., 2017). According to Swanson (2017) and Frederico et al. (2019), supply chain 4.0 can help businesses achieve a competitive edge by increasing product availability, lowering costs, and increasing market share.
A global survey report conducted by G.F. Frederico (2020) illustrated how critical disruptive technologies are for developing supply chain resilience, particularly during the COVID-19 epidemic. Experts from all over the world have agreed or strongly agreed that the industry 4.0 technologies significantly impact supply chain process and responsiveness (G.F. , as shown in Figure 1.

Supply chain 4.0 technologies to tackle the challenges of Covid-19 Pandemic
The automated and digital supply chain may offer the best options for restoring the supply chains that were affected by the COVID-19 epidemic thanks to Industry 4.0 technologies (Reza et al., 2021). In light of Covid-19, a discussion on how supply chain 4.0 technologies can help companies overcome the challenges faced during the Pandemic and improve the supply chain resilience is presented in the following order.  Ghadge et al., 2020;Morella et al., 2020). By allowing real-time data acquisition from devices, operations, and business settings, the increased amount of connection allowed by these technologies can also result in improved decision-making (Bi et al., 2014). C.P.S.s, as one of the critical drivers of Industry 4.0, can enable automated and real-time data capture from various stages across the supply chain, resulting in improved decision-making . Advanced information exchange can result in increased connection and automation, which can substantially affect supply chain performance . C.P.S.s can provide a higher knowledge of the expectations of diverse partners along the supply chain. They can improve coordination and integration between them by permitting a seamless integration and information flow (Cao et al., 2017). As a result, decision-making and adaptability in supply chain operations can be improved Cao et al., 2017), resulting in excellent product delivery and superior customer satisfaction (Fatorachian & Kazemi, 2021) Supply chain operations can be self-executed and managed when IoT is combined with other technologies like cloud computing, artificial intelligence, and robotics Harris et al., 2015;. Sultana and Tamanna (2021) identified several challenges of IoT usage in Bangladesh during pandemic situation. By allowing for increased flexibility and proactiveness (Fatorachien and Kazemi, 2020; G F. , IoT can also enable high responsiveness at the operations level (Oberg & Graham, 2016). In addition, the IoT can allow automated systems by linking intelligent devices, processes, and industrial operations and connecting them to the Internet Li et al., 2016; which increases productivity, profitability, and quality standards (; Tjahjono et al., 2017), resulting in better supply chain operations (G F. . Additive manufacturing may be considered with the goal of boosting production flexibility by mass-customizing output and therefore enhancing supply chain responsiveness and flexibility Kunovjanek et al., 2020). In the factory, augmented reality also plays a significant role in providing increased transparency to the system, increasing readiness, proactively correcting machine and process problems, and ultimately lowering failures and lead time (Rejeb et al., 2020). The combination of cloud computing with IoT, artificial intelligence, and robotics in distribution centers might result in self-executing activities such as obtaining, fetching, putting away and delivering . This could result in significant developments in the distribution supply chain's responsiveness and efficiency. Blockchain technology may also aid with deliveries. Visibility, tracking, and protection make a supply chain more credible and proactive (Casado-Vara et al., 2018;Chang et al., 2019;Hald & Kinra, 2019;Longo et al., 2019;Queiroz et al., 2020;Ramirez-Pena et al., 2019).
Real-time data stream processing and analysis enabled by B.D.A. analytics can lead to significant advancements in real-time decision making and reduction in costs Guo et al., 2015;Li et al., 2016;Ramirez-Pena et al., 2019;Narwane et al., 2020). Big data processing technologies could also create tremendous possibilities in case of planned maintenance and mechanization . B.D.A. can lead to the development of meaningful information for forecasting and planning subsequent conduct and decisions since they enable real-time attention and concurrent evaluation of massive datasets Zhong et al., 2015). Companies can, for example, use B.D.A. to create predictive models to aid in determining the most profit-making consumers (Davenport, 2006;Shmueli & Koppius, 2011) and gaining a better understanding of their needs. As a result, order-taking decision-making and overall supply chain planning can be improved Wamba et al., 2015).

Theoretical framework
Based on the previous studies, following research model has been developed, where different industries' intention to tackle supply chain recovery challenges and implement supply chain 4.0 will be evaluated as shown in Figure 2.

Questionnaire development
Primary data for the study have been accumulated through a structured questionnaire. The questionnaire comprised of three major segments in addition to the demographic information. Demographic information included gender, job title, and type of job. Then the next section, Part 1, consisted of questions about the type of industry they are serving. Part 2 of the questionnaire comprised 16 Supply Chain Recovery challenges statements based on a five-point level of agreement Likert scale. Finally, Part 3 included a statement about the intention to use supply chain 4.0.

Sampling procedure
Researchers selected respondents ascertaining them as supply chain practitioners; hence the sampling method was judgmental sampling. Approximately 75 questionnaires were disseminated online. A total of 55 questionnaires were returned, and among them, 48 fully completed were received, resulting in a response rate of 64%. Among the respondents, 95% were male, and 5% were female.

Participants of the study
The participants of the study are from different industries. The frequency of the participation from different segments is demonstrated below. The highest number of responses have been accumulated from the R.M.Gs industry, and other frequencies have been reported in Table 2.

Statistical treatment of data
SPSS version 28 has been used for analysing the data. Data were elicited from practical field and the numerical data were treated with statistical methods; hence the method is empirical and quantitative. To measure construct reliability, Cronbach's Alpha was used, and research validity and exploratory factor analysis were conducted. For testing hypotheses, the Kruskal Wallis test has been conducted. Further, descriptive analysis such as mean rank and the percentage has been employed.

Reliability and validity of the instrument
Research instrument reliability measures the internal consistency of the items. The reliability test shows the extent to which the instruments of research are error-free. The standard measure of scale reliability and constructs' internal consistency is Cronbach's Alpha (α). Rivard and Huff (1988) stated that the value of Cronbach's Alpha coefficient above 0.70 provides evidence for the reliability and internal consistency of the research instruments. As the Cronbach's Alpha for the identified construct "Supply Chain Recovery Challenges" is 0.920 (Table 4), which is well above 0.70, it shows strong evidence for construct reliability. Moreover, the ranges of Cronbach's Alpha if Item is 0.909-0.923, which is above the standard value of 0.70.  To analyse construct validity, exploratory factor analysis has been performed. Values of factor loading greater than 0.40 are moderately significant, and 0.50 are highly significant (Hair et al 2006). As shown in Table 5 (labeled as S.R.C. 1-S.R.C. 16), the values range from 0.420-to 0.881. Thus, the research instruments' validity is highly significant.   Figure 3 demonstrates the type of industries they are serving. The majority of the participants (37.5%) are from the R.M.Gs sector, where the longer-term impacts of the COVID-19 Pandemic have been emerging (Kabir et al., 2021). The following most significant numbers of respondents (22.9%) are from the service industry. Subsequently, 16.7% of respondents belonged to the food and beverage industry, about 15% were from the manufacturing industry, and 8% were from the pharmaceutical industry. Table 6 illustrates that is no significant relationship between the industries' intention to get oversupply chain recovery challenges as the Asymp. Sig. Value is more significant than 0.05.   Hence, null hypothesis H 0a : There are no significant relations among the varied industries' intention to get oversupply chain recovery challenges-is accepted.

Diverse industries' intention to get over supply chain recovery challenges
Since there is no significant correlation, Table 7 demonstrates the extent of supply chain challenges in different industries. According to Mean Rank, the most disrupted industry by supply chain recovery challenges is Food and Beverage industry. The next impacted industry by the challenges is the Pharmaceuticals industry. Then, the extent of supply chain recovery challenges is observed in R.M.Gs, Manufacturing, and Service industries, respectively. Table 8 illustrates no significant relationship between the industries' intention to implement supply chain 4.0 as the Asymp. Sig. Value is more significant than 0.05. Hence, the null hypothesis H 0b: There are no significant relations among the varied industries' desire to implement supply chain 4.0-is accepted.

Diverse industries' desire to implement supply chain 4.0
Since there is no significant correlation, Table 9 demonstrates the extent of intentions of different industries to use supply chain 4.0. According to Mean Rank, the food and beverage industry is most inclined to adopt supply chain 4.0. Subsequently, the extent of desire to adopt supply chain 4.0 is prevalent in R.M.Gs, Service, Manufacturing, and Pharmaceuticals industries, respectively.

Discussion
The results of hypotheses show that there is no relation between the different industries intention to tackle supply chain recovery challenges and to adopt supply 4.0. This denotes that the intentions among five industries named R.M.Gs, Pharmaceuticals, Food and Beverage, Manufacturing, and Service industries differ. Therefore, the intentions of the industries are ranked (as shown in Table 7 and Table 9). A greater number of previous studies listed the supply chain recovery challenges that supply chain practitioners are facing during Covid-19 pandemic. The present study attempted to evaluate the intention of different industries to deal with the challenges.
M. T. Chowdhury et al. (2020) evaluated short-term and medium to long-term challenges of supply chain in food and beverage industry and suggested a number of management strategies to deal with the challenges. Ali et al. (2019) used DEMATEL method to appraise the risks in food supply chain during pandemic. Hobbs (2020) assessed potential supply side disruptions to food supply chain. The current study supported these findings related to supply chain recovery challenges faced in the food and beverage industry during Covid-19; moreover, found that food and beverage industry has highest intention to tackle the challenges. Next disrupted industry is pharmaceuticals during pandemic as found in the study. A.  explored twelve significant supply chain challenges faced by retailers in pharmacies during this health crisis. The study supported the finding and revealed that pharmaceuticals industry is the next impacted industry by supply chain challenges incurred from pandemic situation. Paul et al. (2021) listed supply chain recovery challenges of Bangladeshi R.M.G. industry during covid-19 pandemic. The current research sustained with the findings of Paul et al. (2021); however, ranked this R.M.G. industry as third industry desire to tackle supply chain recovery challenges. The following ranked industries who have intention to get over supply chain challenges are manufacturing and service industry, respectively. Findings of Paul and Chowdhury (2020) and Hayat et al. (2021) in manufacturing and Sudan and andTaggar (2021) in service industry are supported in this regard.
Large number of literatures stated the supply chain recovery challenges that are addressed by supply chain 4.0 technologies (Table 1). Industry 4.0 technologies that significantly impact the supply chain activities are demonstrated in Figure 1. All studies suggested specific industry 4.0 technologies to address the incurred supply chain recovery challenges during covid-19 pandemic. However, the present study exhibited diverse industries' desire to adopt supply chain 4.0.
The most inclined industry that desires to adopt supply chain 4.0 to address supply chain recovery challenges is food and beverage industry. The finding supports the evaluation of Hobbs (2020) who considers that whether covid-19 pandemic will lead to long-term impacts on food supply chain including the rise of online grocery delivery sector. Such transformation may lead the food industry to use big data analytics to address the challenges. As such, this is the most inclined industry to implement supply chain 4.0. R.M.G industry is the second ranked industry which desires to adopt supply chain 4.0 to recover from supply chain challenges. Paul et al. (2021) suggested for restructuring R.M.G. value chain along with the applications of latest technologies. To improve operational excellence and productivity, Internet of Things (IoT), 3D printing, additive manufacturing, big data analytics are some of the emerging technologies managers may consider Yasmin et al., 2020). The results shown in the study favor these findings; R.M.G. is listed second industry that desires to implement supply 4.0. The subsequent ranks are service, manufacturing and pharmaceuticals industry, respectively, which supports the findings of Belhadi et al. (2021)  The major contributions of this paper are as follows:

Theoretical implication
The study findings have several theoretical implications. While the current literature predominantly focuses on identifying the challenges in supply chain practices (Hayat et al., 2021;Hobbs, 2020;Mashud et al., 2021;Rahman et al., 2021;M. T. Chowdhury et al., 2020) and impact of industry 4.0 technologies on supply chain to address challenges G.F. Frederico, 2020;Hobbs, 2020;Yasmin et al., 2020), this particular study is an early attempt to unearth different industry preparedness and willingness to adopt more resilient practices i.e. supply 4.0 technologies. First, it provides a holistic view of supply chain recovery challenges faced in different sectors of Bangladesh in pandemic situation. Then, the intention to tackle the challenges among different industry is assessed. Finally, the desire to adopt industry 4.0 technologies among the industries is inspected. As such, the findings have strong theoretical implications.

Practical implication
This particular study aims to identify the industry vigilance and willingness to adopt more resilient practices (supply chain 4.0 technologies) among different industries, which will, in turn, pave the way for policymakers to redefine strategies for sustainable supply chain practices in the post-Covid -19 era. Moreover, after learning different industries' intention to tackle challenges and implement supply 4.0, practitioners will be able to make policies for more viable supply chain in particular industry which will in turn benefit the country's economy, environment, and society in post Covid-19 era. For instance, according to study finding, the most intended and prepared industry is food and beverage industry; which suggest that policymakers should redefine the strategies for food supply chain so that the industry can maintain sustainable and resilient supply chain through adopting industry 4.0 technologies. Hence, study results have many practical implications.

Conclusion
The outbreak of Covid-19 influenced diverse industries to gravitate towards supply chain 4.0. Several empirical studies about the technologies to tackle identified supply chain recovery challenges have been reported in the literature. In Bangladesh, global supply chain disruptions lead to challenges in the production system, delivery lead time, and demand and supply (Mashud et al., 2021;Rahman et al., 2021). Therefore, this study inspected the diverse industries' intention to tackle supply chain challenges. Although experts interviewed from different parts of the world have agreed or strongly agreed that the industry 4.0 technologies significantly impact supply chain process and responsiveness, such as IoT 78.7%, Data Analytics 86%, Robotics 73.3%, Blockchain 60.1%, and cloud computing 82.7% (G.F. . Hence in Bangladesh, the intention to adopt supply chain 4.0 is essential to deal with the reported supply chain recovery challenges. In this regard, the desire of diverse industries of Bangladesh to adopt supply chain 4.0 has been examined in this study.
The results identified that there are diverse relations among the varied industries' intention to get oversupply chain recovery challenges. The top two ranked intentions to get over the challenges are evidenced in Food and Beverage industry and the pharmaceuticals industry, respectively. Another finding is the diverse relationships among the industries to adopt industry 4.0 in their supply chain practices. The top two ranked intentions to implement supply 4.0 are evidenced in Food and Beverage industry and the R.M.G. industry.
The supply chain practices in different industries of Bangladesh are facing challenges, and as a result, their intentions are different. Hence, the industries intended to use supply 4.0 to get over the challenges can be recommended with localized supply chain, adoption of supply chain 4.0 on a shorter and longer-term basis (Belhadi et al., 2021), restructuring production system, localizing raw material sourcing, safe and secured labor-management (Kumar, Raut et al., 2020), optimum utilization of limited resources, and maximizing production capacity (Rahman et al., 2021). Moreover, the industries that intend to tackle supply chain recovery challenges are recommended with the supply chain 4.0 technologies as identified in Table 1.
Further study can be performed by specifying more challenges relating to supply chain practices in Bangladesh. Besides, the impact of different challenges on the use of supply chain 4.0 can be explored for the more resilient supply chain management.
