Purpose: This research aims to shed light on the trend of humanitarian supply chain (HSC) studies in the era of pre, during and post coronavirus disease 2019 (COVID-19) pandemic outbreaks. This study provides comprehensive bibliometric mapping published in the 21 top vintage sources globally providing detailed metadata on HSC articles. The manuscript objectives are threefold: to explore the documents that are published in the field of humanitarian logistics and supply chain; second, to identify details of articles in humanitarian logistics and supply chain and thirdly, to explore research the critical area published in the HSC in pre, during and post era of pandemic COVID-19.Design/methodology/approach: This research adopts bibliometric analysis of HSC studies using the Biblioshiny, a shiny app for the Bibliometrix R package. The tool employed in this study decodes the data extracted from the Scopus database to various visualized forms. The review of the HSC studies in this research covers all related publications from 2006 to early 2022. The record of the article was scanned and refined accordingly.Findings: A multi perspectives of HSC studies were explored, discussed and identified. The bibliometric analysis findings offer significant information on the current and future trend publications in the area of humanitarian logistics and supply chain. Additionally, it also provides significant information on the highly cited documents in humanitarian logistics and supply chain studies, most productive contributors, keywords analysis findings, most productive countries and sources, network analysis data on co-occurrence network and themes mapping information in the field of humanitarian logistics supply chain before and after pandemic COVID-19.Research limitations/implications: A multi-perspective of HSC studies was explored only within the online Scopus database. It excludes other articles published in other databases. Future research could explore related articles published in other recognized databases.Practical implications: Practitioners can use multi perspectives findings from pre, during and post-pandemic COVID-19 issues discussed in this paper to get new insight and perception of the issue to facilitate their current and future operation and strategy.Originality/value: To the best of the researchers’ knowledge, this is the first bibliometric study to analyze the trend of HSC studies using Biblioshiny focusing on pre, during and post COVID-19 pandemic. The review highlights annual publication trends, most productive authors, most cited papers, most productive countries, most productive institutions and most productive sources, which leads to a number of future research agendas for future studies.

Purpose: This study aims to discuss the challenges in implementing halal warehouse in the air cargo context along with the standard handling process for the storage of halal product for import and export purposes. This is vital to ensure that halal products do not get contaminated and should comply to halal logistics standard throughout the supply chain process. Design/methodology/approach: This exploratory study adopts single case study to better understand the definition of halal warehouse, the challenges in implementing halal warehouse and also the standard handling process for the storage at the warehouse for import and export purposes. A well-guided case study protocol is followed. Findings: Five categories have found to be the main challenges in implementing halal warehouse. They are coded as halal product trade, halal asset and facility, halal standard of procedure, human factor and perspectives between logistics provider and halal agencies. With regard to standard handling process for import and export purposes in airgo context with compliance to Shariah at the halal warehouse, there are seven main steps involved for import and nine steps involved for export. Research limitations/implications: As this paper is among the pioneer study that looks into halal warehouse implementation, it has some limitations. Further empirical study in a bigger context may be performed quantitatively, and multiple case study approach may also be adopted to get deeper insight in understanding halal warehouse implementation domain of study. Practical implications: This study contributes to the understanding on the gap in the field with adhering or complying with the practice. It will provide input to the authority in understanding the current limitation and suggestion by the practicing companies. Social implications: Halal requirement in non-Muslim countries are not very well implemented and understood, whereby the understanding of the concept of Halalal Toyyiban throughout the supply chain process is critical. The main aim of halal logistics is to avoid cross contamination between halal and non-halal product during the transport, at the storage in warehouse and also in handling. This study contributes to the understanding of halal warehouse implementation. Originality/value: There is a critical dearth of academic study that focuses on halal logistics specifically in transport and warehouse. This empirical case study provides basic understanding of implementing halal warehouse and presents the challenges and also required guidelines in handling halal product at the warehouse for both import and export purposes.

Purpose: The supply chain (SC) encompasses all actions related to meeting customer requests and transferring materials upstream to meet those demands. Organisations must operate towards increasing SC efficiency and effectiveness to meet SC objectives. Although most businesses expected the coronavirus disease 2019 (COVID-19) pandemic to severely negatively impact their SCs, they did not know how to model disruptions or their effects on performance in the event of a pandemic, leading to delayed responses, an incomplete understanding of the pandemic's effects and late deployment of recovery measures. Therefore, this study aims to consider the impact of implementing Bayesian network (BN) modelling to measure SC performance in the airline catering context.Design/methodology/approach: This study presents a method for modelling and quantifying SC performance assessment for airline catering. In the COVID-19 context, the researchers proposed a BN model to measure SC performance and risk events and quantify the consequences of pandemic disruptions.Findings: The study simulates and measures the impact of different triggers on SC performance and business continuity using forward and backward propagation analysis, among other BN features, enabling us to combine various SC perspectives and explicitly account for pandemic scenarios.Originality/value: This study's findings offer a fresh theoretical perspective on the use of BNs in pandemic SC disruption modelling. The findings can be used as a decision-making tool to predict and better understand how pandemics affect SC performance.

Rheological behaviour is an important factor affecting the flow behaviour of a fluid and many aspects related to this, mainly in the manufacturing process of fiber reinforced composites, either for Newtonian fluids or non-Newtonian fluids. During impregnation process, the viscosity changes with temperatures and their strain rate, has influenced the resin flow behaviour during curing process. In this paper, a review on the rheological studies of fiber reinforced composites for both, synthetic and natural based fibers, respectively, are presented. In addition to that, this review paper highlighting a few research studies conducted in literature on the main factors that affecting the rheological quality and performance of the composites. The aims of this review, mainly to capture the trend ranging from the recent five years back and summarize the various studies via experimental, theoretical or modelling works. Furthermore, also aiming to provide an ideal baseline information in the selection of the methods regarding rheological study to ensure better quality of pre-preg product and fibre reinforced composites can be produced in the author’s future work.
