DYNAMICS OF GVC POSITION OF V4 AUTOMOTIVE SUPPLIERS: IMPLICATIONS FOR PUBLIC POLICY

In the post-covid world, governments explore options to enhance their policies so that corporations can act as successful motors of recovery and sustainable growth. Countries select various objectives related to global value chains (GVC), such as participation, value capture, inclusiveness and resilience, yet might be unaware of the position of corporations they are supposed to motivate. In this paper, we aim to (re-)investigate the position of Visegrad Four (V4) suppliers within the regional automotive value chains and to compare results with suppliers in other EU member states using the trade in value added (TiVA) statistics. We set two research questions: How does the position of V4 in automotive GVCs differ from the positions of other EU member states and significant other automotive-producing countries? What is the link between the domestic value added in gross exports of final automotive products and the selected policy variables? A multiple linear regression model is run with TiVA in the automotive industry as the dependent variable and independent variables embodying proxies of GVC-oriented policy consequences. The analysis identifies significant differences in value-added levels between V4 countries and other EU countries, and other large automotive-producing economies. Labour costs, productivity, investment in R&D and innovation support are among the factors where V4 countries fall behind. Implications for Central European audience: The results of our research might be helpful for respective authorities and governments in V4 and other Central and Eastern European countries. They can be of use when setting goals and implementing policies targeted at promoting innovation, upgrading within existing GVCs and in cooperation between universities and research centres on the one hand and the automotive industry on the other. © 2023, Central European Business Review.

FACTORS PRECEIVED TO INFLUENCE THE PERFORMANCE OF PUBLIC SECTOR EMPLOYEES WITH MEDIATING EFFECT OF EMPLOYEES SATISFACTION, A CASE STUDY OF CIVIL DEFENCE DIRECTORATE

In developing countries like Pakistan, mostly the public sector departments give not as much of focus on the performance / capacity building as well as the satisfaction of the employees, the research was conducted to know the influence of the factors perceived on the performance of public sector employees by increasing satisfaction and for this purpose the Civil Defence Department was selected. The study was conducted on the mixed method approach in which both qualitative and quantitative methodologies were adopted to know the responses of the employees of the Civil Defence Department regarding research objectives. Questionnaires, both in open ended and close ended format were distributed among 100 employees of the Civil Defence Department as per the availability of the skeleton staff during COVID-19. The hypotheses were equipped to recognize the significance relationship of variables as well as statistical analysis was applied through SPSS to examine the acceptance or rejection of the hypothesis. Hence, the result instigated that factors perceived in this study have significance influenced on the performance and satisfaction of the public sector employees.

Value-Added Tax (VAT) Development and Reform History—A Study of VAT Evolution Around the World and in China

Value-added Tax (VAT), a turnover tax levied on the value appreciated in commodities production, circulation and sale, has been widely practiced by economies worldwide for its neutrality. From the international perspective, European Union VAT and New Zealand VAT stand out as characteristic models of VAT development and reform history. With changing economic development models and the growth of e-commerce businesses, VAT systems have been upgraded to meet taxation challenges brought about by the digital economy. Recently, VAT policies and measures have been introduced particularly to combat the COVID-19 impact. In China, the VAT system has been reformed constantly over the past 40 years and has been converging with international practice. China now needs to address emerging VAT issues through legislation, tax incentives, and tax-rate grades so as to meet challenges in VAT collection and management and to suit the "new normal” of economic development. © 2022 Brill Academic Publishers.

Women's Participation in Firms' Management and Their Impact on Financial Performance: Pre-COVID-19 and COVID-19 Period Evidence

At a time when gender equality is a key priority of all international organizations, this paper can be considered a remarkable contribution to the role of women executives in firms' performance. More specifically, this study focuses on the effect of women holding positions of responsibility on firms' performance worldwide. For the purposes of our research, we applied cross-sectional and panel data analysis for all sectors at an international level from 2019, the year preceding the breakout of the pandemic crisis, to 2021, while the indicators used to measure the participation of women in executive positions are classified as ESG indices. The empirical analysis findings end up showing that the participation of women in executive positions positively affects firms' performance over time, while there is no material change observed before and during the COVID-19 pandemic period. More specifically, when the percent of women processing job positions of responsibility increases by 10%, then the index of profitability will increase from 1.4% to 1.8%, regardless of the measurement of female participation in executive positions used. The results of this study constitute a remarkable contribution to the promotion of the creative economy, the progress of societies, and sustainable development. The research's outcome can be primarily used by policymakers drawing up policies for achieving gender equality in the labor market and workplaces and by shareholders and firms' managers in order to trust females in executive positions in favor of their firms' financial performance. The current study is unique in that it focuses on the period before and during the COVID-19 period, as a period of high volatility in economic activity worldwide, while the sample includes firms from large and mid-cap companies belonging to developed and emerging markets. The above approach will contribute to providing more credible information related to the role of women executives in firms' performance.

Economically viable flower drying techniques to sustain flower industry amid COVID-19 pandemic.

Imposing lockdown amid COVID-19 pandemic has severely affected flower cultivation and their trades. Flower plants are very sensitive to the harvesting, and any unexpected delay may cause great loss (~ 50-60%) to the farmers. In 2018-2019, the worth of total production of floriculture products was ~ Rs 571.38 crore. During lockdown, the availability of human laborers and restricted transport has disrupted the supply of flowers to the market. Hence, some alternative options are suggested here for the farmers, for example, conversion of decorative flowers (e.g., anthurium, China aster, globe amaranthus, sweet-william, anemone, sea lavender, etc.) and inflorescence (e.g., Michaelmas daisy, zinnia, statice, ferns, aspidistra, eucalyptus, magnolia, etc.) can also be into value-added products through drying and dehydration technologies. Many dehydration methods such as hot air oven, solar drying, press drying, freeze-drying, embedded drying, glycerine drying, and microwave oven drying polyester drying can be used for flower drying at room temperature (~ 25 °C). These floral and foliage dehydration techniques are quite simple, which can also be operated by unskilled persons. Moreover, it will generate self-employment for the youth and women along with increased revenue than selling fresh flowers. In this review, different techniques of flower drying have been discussed in detail along with the influencing factors, efficiency, economic feasibility, flower waste management and sustainability. Further, it has also been suggested how these techniques could be useful for farmers, researchers, and traders to create value-added products? Hence, the present paper could be very interesting for the flower growers, retailers, students, as well as floricultural scientists who are involved in flower production worldwide.

Study on the contribution of coastal tourism to marine economic development

Since the reform and opening up, coastal tourism has been rising and developing, and it has become one of the important marine industries. This paper selected the added value and gross marine product of coastal tourism industry from 2001 to 2020, constructed direct contribution rate, indirect contribution rate and marginal contribution rate model, and calculated the contribution degree of coastal tourism to marine economic development. The results showed that the direct contribution rate of coastal tourism was on the rise, and the indirect contribution rate was mostly about 2%~4%.In the selected study period, the marginal contribution rate of coastal tourism to GROSS marine product was 40.44%. The study found that the overall development level of coastal tourism was good, and the coastal tourism made a great contribution to the development of marine economy, but it was difficult to take accurate measures in the face of sudden crises such as COVID-19, and sometimes it took a lot of time to recover to the normal level. Based on the above situation, suggestions were proposed to increase policy support for the post-epidemic era, promote the supply-side reform of coastal tourism and build coastal tourism products with characteristics in the post-epidemic era, increase the publicity and marketing of coastal tourism, and train and introduce high-quality tourism talents, etc..

GLOBAL PRODUCTION NETWORKS IN THE REGIONAL ANALYSIS FRAMEWORK: CASE OF THE EU PERIPHERAL AUTOMOTIVE MANUFACTURING

Recent transformations following the global financial crisis of 2009, COVID-19 pandemic, supply chains disruptions and newest shocks have radically reshaped global production landscape and challenged comparative benefits of global production networks (GPN) vs global value chains (GVC) paradigms in international production analysis. The study tests the hypothesis that GPN concept allows for a better identification of structural shifts in international production structures while revealing regional patterns of cooperation. In the first section, the main methodological constraints of GVC paradigm are specified. Additionally, the reasons for the application of network-based approach to international production are outlined. The second section dissects the EU automotive manufacturing to support the theoretical propositions. While comparing GVC and GPN quantitative toolkits, the possible trade-off has been reached which is to calculate network indicators (transitivity, centrality, etc.) on the inter-country input-output tables. As a result, the hypothesis was confirmed. Specifically, betweenness centrality metric suggests that Czechia and Slovakia have immediately favoured a positive effect of the entry into the EU, whereas neither of GVC indicators reveals such a shift. Simultaneously, 2008 crisis is depicted via GVC indicators, whilst network metrics suggest no structural changes in the production system. These results corroborate to our theoretical juxtaposition of GVC/GPN approaches. The methodological cohesion of two sets of indicators further advances the views on European regional core-periphery integration and automotive production networks dynamics. At the same time, the findings may contribute to the reassessment of regional integration developments in Europe, as well as in Latin America and Eurasia. © González G. H., Sapir E.

Do women on boards enhance firm performance? Evidence from top Indian companies

This paper examines whether gender diversity (GD) on corporate boards influences financial performance (FP) of Indian firms using System Generalized Methods of Moments (GMM) methods by considering panel data of 364 firms during 2017 to 2021, comprising of 1820 firm-year observations. The study reveals that the mere presence of a woman director (WD) on boards makes no difference in financial performance. Presence of WDs as a significant portion of the boards and their active roles in the functioning and governance of companies positively contribute to firms' financial performances and economic value creation. Regarding other governance parameters, the study shows that larger boards do not necessarily improve firm performance. Also, independent directors do not necessarily add value to corporate performance and value creation. While a higher promoter's stake is an important factor for Indian companies to drive corporate performance, firms with separate CEO and chairperson outperform firms with CEO duality. The study also reveals that the covid 19 pandemic has negatively influenced the financial performance and economic profit generation of the Indian firms. This study is important for several reasons. First, this study considers the period (2017–2021) when Indian companies adopted new financial reporting practices (IND-AS) in line with International Financial Reporting System (IFRS), the mandatory quota system of women directors' appointment is implemented and new corporate governance norms are implemented. Hence, our study contributes to the literature by proving meaningful insights on the role of gender diversity and other corporate governance parameters on financial performance of Indian firms in the light of newly adopted accounting and financial reporting practices. Second, few previous India based studies have mostly used pooled OLS or fixed effect models, and did not address the endogeneity problem in different forms like Dynamic Endogeneity, Simultaneity, and Unobserved Heterogeneity. This paper addresses the endogeneity problem appropriately by using the system generalized method of moments (GMM) while modelling the relation between WDs and firms' FP. Therefore, the findings of this study are more reliable and unbiased and can be useful for effective policy making on gender diversity and corporate governance issues. Third, few prior studies which have looked into the role of WDs on FP of Indian firms, have mostly used return on assets (ROA), return on equity (ROE) and Tobin's Q as performance parameters. Here, in addition to ROA, ROE and Tobin's Q, we also use economic value added (EVA) as indicators of corporate performance to understand the role of WDs on economic value creation for companies. The EVA is considered as modern technique to measure the economic profit earned by a firm, and it has gained huge popularity among companies as an improved technique for measuring financial performance for companies. To the best of our knowledge, the role of WDs on economic value creation by firms has not been investigated before particularly in the Indian context. This is another unique contribution of this study. Fourth, the Covid 19 pandemic had impacted global economy severely and India was no exception. Financial performances of most Indian firms were negatively impacted due to the nationwide lockdown and uncertainties about production, revenue and earnings. This study considers both the pre and post Covid 19 pandemic period in examining our central research question using a year dummy. Therefore, our study also captures whether the covid 19 pandemic has actually impacted the financial performance of Indian firms, while modelling this relation. This is another valuable and unique contribution of this study to the literature. The findings of this study provide an understanding of how board gender diversity and other governance parameters influence financial performance of Indian firms in an emerging market context. The outcomes are also explained and aligned with the relevant policy implications in th light of recent Indian corporate governance norms and policies. These findings are useful to the companies and policymakers, as they can use these findings while designing effective boards, which can be useful in improving firm performance. Board of directors, investors, regulators, and policymakers can effectively use these findings to understand how gender diverse boards and other corporate governance parameters influence firms' financial performance under the concentrated ownership pattern.

Applications of waste-to-economy practices in the urban wastewater sector: implications for ecosystem, human health and environment

Waste generation has steadily increased over the last few decades, owing to rising population and rapid industrial development. By 2050, the world is expected to generate 3.40 billion tons of waste per year, up from 2.01 billion tons today. Waste mismanagement has negative consequences for human health and the environment, while also contributing to climate change. To reduce waste generation, resources must be used and reused in a sustainable manner so that they do not end up in landfills. Waste-to-economy (WTE) is a feasible approach with enormous potential to contribute to waste management sustainability while also generating economic benefits. The transition from a linear to a circular economy, in which waste is recycled, reused, and used as a resource, may provide a significant opportunity to generate significant wealth or economic benefits, as well as positive environmental and health implications, particularly in the urban water sector. Long-term direct and indirect economic, ecological, and human health benefits may result if global environmental pollution is reduced, resulting in a corresponding reduction in morbidity and mortality at endpoint impacts. The importance and implications of waste to economy practices in the urban water sector have been discussed in this chapter. This approach could be extremely beneficial in countries dealing with a water crisis. The 6R principle of reduce, recycle, reclaim, recover, reuse, and restore can be used to reduce water stress. As a result, water demands could be met with some considerations, as well as the generation and recovery of value-added products from wastewaters. The transition from a linear economy to a WTE approach, however, carries the risk of negative environmental and human health consequences associated with the production and reuse of recycled materials. Aside from that, the effects of WTE applications on ecosystems, the environment, and human health are mostly positive. This chapter discussed the need for and application of WTE principles in the urban water sector, as well as the associated positive and negative environmental, economic, and health implications, as well as some recommendations. © 2022 Elsevier Inc.

Do South Africa's e-commerce VAT rules measure up to international trends and OECD guidelines?

Orientation: The taxability of e-commerce transactions have been the subject of many studies to protect governments from Value-Added Tax (VAT) erosion, illegal recovery and fraud. Research purpose: This study critically analyses the challenges posed by e-commerce transactions in South Africa's VAT Act . Recommendations are made for amendments to the VAT Act to improve rules to effectively tax e-commerce transactions occurring in South Africa. Motivation for the study: Globally, including in South Africa, enforcing relevant VAT legislation to target output tax collections and input tax credits from e-commerce transactions aptly remains a challenge. Research approach/design and method: By integrating qualitative literature reviews and comparative synthesis, this study employed a comparative legal methodology. VAT levied on e-commerce transactions in South Africa is compared to the Organisation for Economic Co-operation and Development's guidelines as well as New Zealand's and Australia's Goods and Services Tax legislations. Main Findings: While the South African VAT Act aligns with international best practices on the use of intermediaries, there are some differences as detailed in the study. Practical/managerial implications: To align with international trade counterparts, the South African VAT Act should differentiate between business-to-business and business-to-consumer sales. A provision concerning the place of consumption for bundled goods should be included in the VAT Act . The VAT Act should contain a provision that allows bad debts to be claimed on cash sales made instead of total sales made. Contribution/value-add: This study harmonises South African VAT legislation with international best practices within the context of continual advancement of e-commerce transactions.

COVID-19 vaccination telephone outreach: an analysis of the medical student experience.

INTRODUCTION: The COVID-19 pandemic diminished opportunities for medical students to gain clinical confidence and the ability to contribute to patient care. Our study sought out to understand the value of telephone outreach to schedule COVID-19 vaccines on medical student education. MATERIALS AND METHODS: Forty students engaged in telephone outreach targeting patients aged 65+ without active patient portals to schedule COVID-19 vaccines. Data consisted of a single administration retrospective pre/post survey inquiring about what students learned, expectations, other health-care processes that would benefit from outreach, and interest in a population health elective. Likert items were analyzed and open response analysis involved inductive coding and generation of thematic summaries by condensing codes into broader themes. Demographic data of patients called and subsequently received the vaccine were also collected. RESULTS: There were 33 survery respondents. There was a statistically significant increase in net comfortability for pre-clerkship students for documenting in Epic, providing telehealth care, counseling on common health-care myths, having challenging conversations, cold-calling patients, and developing an initial trusting relationship with patients. The majority called and who received the vaccine were non-Hispanic Black, within the high SVI category, and had Medicare and/or Medicaid. Qualitative data showed that students emphasized communication, the role of trusted messengers, the need to be open minded, and meeting patients where they are. DISCUSSION: Engaging students in telephone outreach early in the COVID-19 pandemic provided students the opportunity to develop their skills as physicians-in-training, contribute to combating the ongoing pandemic, and add value to the primary care team. This experience allowed students to practice patience, empathy, and vulnerability to understand why patients had not received the COVID-19 vaccine; this was an invaluable experience that helped students develop the skills to become empathetic and caring physicians, and supports the continued role of telehealth in future medical school curriculum.

Comparing media coverage of the pharmaceutical industry: pre- and post-pandemic lockdown

PurposeThe purpose of this paper is to analyze media coverage of the pharmaceutical industry before and after the COVID-19 lockdown to determine whether the coverage changed in light of a global health-care crisis and the fast-track development of vaccines and antiviral treatments.Design/methodology/approachThe top five US newspapers were audited, comparing the 12-month periods before and after March 2020 coinciding with the pandemic lockdown, yielding 493 front-page articles and editorials. Each headline and full-text article was separately analyzed and categorized as either positive, negative or neutral toward the pharmaceutical industry. A frequency analysis of the hot button issues covered in each article was conducted.FindingsYear 1 and Year 2 audit results were compared to identify changes in media coverage pre- and post-lockdown. The amount of coverage of the industry increased 145% and the tone of both headlines and articles shifted dramatically. Only one of the five newspapers had a net positive article rating of the industry pre-lockdown, four of five were net positive post-lockdown. The proportion of positive headlines increased 165%. The top issues discussed in the coverage shifted from persistent challenges for the industry (e.g. opioid crisis, high cost of drugs) to the emergence of the virus and status of vaccine development.Originality/valueThis research establishes how media coverage of the pharmaceutical industry changed as the industry responded to a global health-care crisis and identifies implications for industry stakeholders.

A Lean Six Sigma case study to improve the manufacturing process affected during COVID-19

The key manufacturing industry was badly affected by the COVID-19 in India. In this study, we found that the product demand is dynamic during COVID-19. We selected one of the electrical OEMs in India to execute the value added-Flow analysis and VSM study which showed 96% and 85% of total delivery lead time is contributed by NVA activities at the manufacturing process respectively. We also plotted the spaghetti diagram and analysed that total product movement is 287 metres in the current state with the complex flow. We did total of six main Kaizens after Ishikawa and FMEA. We constructed single-piece flow with saving of the half shop floor space and total product movement was reduced from 287 to 96 metres, while total delivery lead time was reduced from 14.6 to 7.72 days. We concluded that lean Six Sigma deployment in the manufacturing industry solved the problems of demand fluctuations.

Research progress in high value-added utilization technology of waste plastics

The low degradability of waste plastics will continue to pollute the environment, and the spread of the COVID-19 has exacerbated the use and accumulation of plastics, and thus the efficient treatment of waste plastic resources has become an urgent technical problem to be solved. By analyzing several mainstream waste plastics treatment technologies, it was clear that resourceful and high value-added utilization technology was the most competitive and environmentally friendly waste plastics treatment route in the market. The research progress of high value-added utilization technology of waste plastics at home and abroad in recent years were reviewed. The development and variation of conventional thermal cracking technology were discussed. Through this route, the highest yield of waste plastics into fuel products can reach 97%—98%. It was pointed out that the conversion of waste plastics into jet fuel, high value-added chemicals and functional materials for special applications through chemical, catalytic and biological technologies was the mainstream research direction and development trend in this field. Among them, the yield of conversion to high value-added monomer could reach more than 97%, so as to realize the upgrading of plastic waste from the primary treatment stage of "waste clearance” to "turning waste into use” and "turning waste into treasure”, and help China achieve the goal of "double carbon”。. © 2023 Chemical Industry Press.

Photoredox-Catalyzed Plastic Waste Conversion: Nonselective Degradation versus Selective Synthesis

Plastic waste pollution is becoming one of the most pressing environmental crises due to the large-scale production without satisfactory recycling schemes, especially with the outbreak of the COVID-19 pandemic in recent years. Upcycling of plastic waste into valuable chemicals powered by solar energy presents a substantially untapped opportunity to turn waste into treasure. In this review, the fundamental principles from plastic nonselective degradation to selective synthesis are first clarified. Then, we aim to outline the representative recent advances in photoredox-based catalytic plastic waste conversion. Particular emphasis is placed on the valorization of plastic waste regarding nonselective degradation versus selective synthesis. Finally, we present challenges and individual insights for further exploration of the plastic waste conversion domain. It is anticipated that this timely and critical review would provide an instructive direction and foresight on the selective conversion of plastics to value-added chemical feedstocks, thus stimulating the development of a circular and sustainable plastic economy in the coming decades. © 2023 American Chemical Society.

Exploring the potential impact of instructional time and high school scheduling formats on student growth in Pennsylvania

High schools must format the master schedules and designate a specific number of instructional minutes to help promote student growth. School leaders that attempt to enhance Pennsylvania Value-Added Assessment growth scores need an opportunity to utilize a master schedule that fits their needs and to support continued growth. With the emergence of the COVID-19 pandemic, school leaders must adapt and create organizational changes to promote student growth and address learning loss. Every public high school in Pennsylvania follows a specific master scheduling format and a specific number of instructional minutes for Keystone-tested subject areas. By examining how Pennsylvania high schools utilize a master schedule, coupled with particular school circumstances, there are teachable moments for understanding how to create a master schedule in schools best to promote student growth. This quantitative study involved 59 public high school leaders as survey participants, with individual survey responses about their school buildings, coupled with public domain data from the Pennsylvania Value-Added Assessment System. This study revealed no statistically significant differences in scheduling formats for a block or traditional model, nor statistically significant differences in instructional minutes related to student growth or scheduling models. However, one statistically significant difference was Biology instructional minutes related to scheduling format. By learning how master schedules work in Pennsylvania high schools, one can use this research data to promote effective scheduling changes to enhance student growth and schoolwide performance.

The assessment and improvement of the value chains and added value of agricultural commodities in the south of Libya: with a special emphasis on women's livelihoods

This report first describes the context of the agriculture sector in Libya and in the south of the country, the impact of the ongoing conflict in the country since 2011 and of the COVID-19 pandemic, and the specific configuration of the sectors in the south of the country. Secondly, it describes the main challenges in the value chains and added value of selected major crops cultivated in the south of Libya, providing an analysis and assessment of the cooperatives and associations in the region with significant involvement and participation of women. The value chains and added value have been evaluated and characterized for four crops (tomatoes, watermelons, mangos and dates). The study found the value chains of the assessed crops to be highly deficient, with almost no proper postharvest handling practices, and there is an almost total lack of added value. Surveys, interviews and studies in the region have identified three types of involvement of women in food and/or agriculture: (1) very few women are members of classical agricultural cooperatives;(2) some women are members of civil society organizations (CSOs) involved in agricultural and/or food activities;and (3) many individual women not associated with groups, associations and cooperatives perform some agricultural and/or food activities.

The article highlights the benefits reaped by the Kibuyuni Seaweed Women, one of five seaweed groups supported by the project.

Impact of Covid-19 on economic recovery: empirical analysis from China and global economies

This research aims to utilize quarterly global VAR data from April 1, 2020, to September 30, 2021, to assess the influence of the economic recovery of China following the COVID-19 outbreak on global economies. China is one of the first big economies globally to show indications of recovery following the COVID-19 pandemic. The nation's economic growth has the biggest long-term influence on middle-income nations (0.17%) followed by low- and middle-income economies (0.16%) and high-income economies (0.16%) (0.15%). The chain reaction of China's economic growth is most visible in high-income nations (0.11–0.45%), followed by middle-income countries (0.08–0.33%) and low-income countries (0.02–0.05%). Our findings show that the post-COVID-19 economic rebound in China will mostly benefit middle-income nations, with low- and middle-income countries following closely after. After COVID-19, the influence of the economic recovery of China is most visible in the rise of energy consumption in high-income nations, followed by middle-income economies. It is also worth noting that the influence of China's economic expansion on low- and middle-income economies does not always imply a rise in energy consumption. Overall, China's economic recovery has a significantly stronger influence on other countries' economic development than other countries' energy consumption has on other economies' growth.

Optimization of Transport Services Based on the K Shortest Path Algorithm

The link between the supply and demand sides of manufacturing has become increasingly frail as a result of the COVID-19 outbreak. In this paper, we analyze the key path nodes and propose a closed-loop path value-added strategy for logistics services to optimize the path cost on the supply and demand side under the influence of the COVID-19 epidemic. First, the k shortest path algorithm determines the optional paths in accordance with the structure of the road network made up of all path nodes. Second, closed-loop transportation routes for both forward and reverse transit are constructed using the optional paths. Finally, the transportation service strategy with the optimal choice of transportation cost and transportation time under a multi-stage epidemic is obtained. The method can provide a reference for logistics services. © 2022 IEEE.
