Forskningsöversikt (refereegranskat)abstract
- PurposeThe purpose of this paper is to review existing research on retail supply chain responsiveness, develop categories to be included in a retail-specific responsiveness framework, and identify future research areas within the scope of retail supply chain responsiveness.Design/methodology/approachThis paper presents an inductive systematic literature review of 46 academic, peer-reviewed articles. Based around the two major review questions on retailers’ role in the creation of supply chain responsiveness and future research areas, an inductive, qualitative, content analysis was conducted. Further analysis was conducted by using the software NVivo 11.FindingsExisting research are grouped into a framework of four categories that together span the existing research. The categories are labelled supply chain orchestration, market orientation, supply chain operations and supply management. Two to three subthemes in each category are presented. Thereafter, promising future research areas are outlined, covering methodological issues, theoretical underpinnings, inclusion of context variables and outcomes of retail supply chain responsiveness.Research limitations/implicationsThe conducted systematic literature review has been limited to academic, peer-reviewed articles.Practical implicationsThe findings of the paper constitute a promising initial step towards a retail-specific framework on retail supply chain responsiveness.Originality/valueThe paper questions the comprehensiveness of established models in responsiveness, and argues that existing “general” literature on supply chain responsiveness gives little guidance and structure to retailers’ specific role and involvement in supply chain responsiveness. In particular, the paper focusses on the retailers’ role for creation of supply chain responsiveness, which has not previously been addressed in research.

Analytics for supply chain resilience : Exploring paths and obstacles
- 2023
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Supply chain disruptions, ranging from epidemics to geopolitical tensions, have been especially evident in recent years and have consequently become a hot topic in both boardrooms and academic literature. Supply chain resilience (SCR) denotes the ability to prepare, respond, recover, and facilitate growth during disruptions and is usually thought of as consisting of several enablers. Initial evidence suggests that one such enabler could be analytics, which broadly refers to the processing of data to support decision-making. This thesis aims to explore the use of analytics for SCR. The research design comprise one conceptual component followed by two empirical components consisting of a survey and interviews. The findings reveal six application areas for analytics in SCR. Three paths to SCR are also identified in terms of configurations of analytics and other SCR enablers, only one of which does not seem to be contingent on the level of supply chain complexity. Finally, obstacles to the use of analytics were identified. Clear consensus was noted for low data availability and/or quality as a major obstacle to SCR, while a somewhat consensus existed concerning the hindrance to quick decision-making, lack of a data-driven culture, and insufficient benefits and/or use.The thesis contributes to the nascent stream of research on the use of analytics and SCR by complementing individual observations with broader and deeper insights through the spectrum of application areas, configurations of analytics and complementary SCR-enablers, and finally, obstacles. For practitioners, the thesis provides insights into using analytics as a potential enabler for SCR. Firms can evaluate their current use of analytics for SCR and adjust their set of application areas and configurations of SCR-enablers as per the options outlined in the findings to better align with their specific needs and prerequisites. Finally, guidance is provided on what obstacles to be cognizant of and attempt to mitigate.

Tidskriftsartikel (refereegranskat)abstract
- This paper develops a robust stochastic optimization model for reverse logistics in closed-loop supply chains. By determining the optimal flow of products using a Chance Constrained Robust Stochastic Programming (CCRSP), it is highlighted how the number of plant openings is influenced by the changes in carbon credit price. To assess the model performance, a set of numerical experiments in different sizes are developed and conducted. The effectiveness of the results are then compared to a proposed Heuristic Hybrid Taguchi PSO (HTPSO) solution algorithm, which underlines the effectiveness of the model. A sensitivity analysis on the carbon emission rate is carried out which underlines the role of Carbon Tax Policy. Finally, a real-lifecase study within the automotive manufacturing industry is carried out by applying the developed robust stochastic model. From a practical standpoint, the model can potentially be employed to meet the carbon credits that are used for handling the different carbon prices and trade scenarios. Also, it provides insights on how tobetter manage uncertainties, as well as to reduce the overall emissions in supply chains.

- Background Combating viral hepatitis is part of the UN Sustainable Development Goals (SDGs), and WHO has put forth hepatitis B elimination targets in its Global Health Sector Strategy on Viral Hepatitis (WHO-GHSS) and Interim Guidance for Country Validation of Viral Hepatitis Elimination (WHO Interim Guidance). We estimated the global, regional, and national prevalence of hepatitis B virus (HBV), as well as mortality and disability-adjusted life-years (DALYs) due to HBV, as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. This included estimates for 194 WHO member states, for which we compared our estimates to WHO elimination targets. Methods The primary data sources were population-based serosurveys, claims and hospital discharges, cancer registries, vital registration systems, and published case series. We estimated chronic HBV infection and the burden of HBV-related diseases, defined as an aggregate of cirrhosis due to hepatitis B, liver cancer due to hepatitis B, and acute hepatitis B. We used DisMod-MR 2.1, a Bayesian mixed-effects meta-regression tool, to estimate the prevalence of chronic HBV infection, cirrhosis, and aetiological proportions of cirrhosis. We used mortality-to-incidence ratios modelled with spatiotemporal Gaussian process regression to estimate the incidence of liver cancer. We used the Cause of Death Ensemble modelling (CODEm) model, a tool that selects models and covariates on the basis of out-ofsample performance, to estimate mortality due to cirrhosis, liver cancer, and acute hepatitis B. Findings In 2019, the estimated global, all-age prevalence of chronic HBV infection was 4 center dot 1% (95% uncertainty interval [UI] 3 center dot 7 to 4 center dot 5), corresponding to 316 million (284 to 351) infected people. There was a 31 center dot 3% (29 center dot 0 to 33 center dot 9) decline in all-age prevalence between 1990 and 2019, with a more marked decline of 76 center dot 8% (76 center dot 2 to 77 center dot 5) in prevalence in children younger than 5 years. HBV-related diseases resulted in 555 000 global deaths (487 000 to 630 000) in 2019. The number of HBV-related deaths increased between 1990 and 2019 (by 5 center dot 9% [-5 center dot 6 to 19 center dot 2]) and between 2015 and 2019 (by 2 center dot 9% [-5 center dot 9 to 11 center dot 3]). By contrast, all-age and age-standardised death rates due to HBV-related diseases decreased during these periods. We compared estimates for 2019 in 194 WHO locations to WHO-GHSS 2020 targets, and found that four countries achieved a 10% reduction in deaths, 15 countries achieved a 30% reduction in new cases, and 147 countries achieved a 1% prevalence in children younger than 5 years. As of 2019, 68 of 194 countries had already achieved the 2030 target proposed in WHO Interim Guidance of an all-age HBV-related death rate of four per 100 000. Interpretation The prevalence of chronic HBV infection declined over time, particularly in children younger than 5 years, since the introduction of hepatitis B vaccination. HBV-related death rates also decreased, but HBV-related death counts increased as a result of population growth, ageing, and cohort effects. By 2019, many countries had met the interim seroprevalence target for children younger than 5 years, but few countries had met the WHO-GHSS interim targets for deaths and new cases. Progress according to all indicators must be accelerated to meet 2030 targets, and there are marked disparities in burden and progress across the world. HBV interventions, such as vaccination, testing, and treatment, must be strategically supported and scaled up to achieve elimination.
