Based on theories of composite sheets, the generated stresses in a stratified composite loaded in monotonic tensile are composed of the σ_x, σ_y and τ_xy components, which are situated in the plane of the sheet. In fact in the interface of different layers, the σ_z normal stress and τ_xz and τ_yz shear stresses, normal to the plane are also generated, which are amplified in the vicinity of the holes. The generation of the interlaminar stresses is due to the difference in the poisson ratio between two neighbour layers. These interlaminar stresses lead to delamination and the failure of the composite. The evaluation of the value and the situation of these stresses would be useful to prevent the failure of the stratified composite by delamination. For this purpose a model composed of three dimensional 20- nodes quadric brick element was developed. The stratified composite with a hole in its center was loaded under monotonic tensile. The computation of stresses was carried out using Ansys software. The result was that interlaminar stresses were obtained for six different lay up sequences of the T300/934 CFRP composites. These results will be the base for the evaluation of delamination of the corresponding composite.

The complex network structure causes several disruptions in the supply chain that make risk management essential for supply chain management including halal supply chain (HSM). During risk management, several challenges are associated with the risk assessment phase, such as incomplete and uncertain information about the system. To cater this, the authors propose a risk assessment framework that addresses the issues of uncertainty using neutrosophic theory and demonstrated the applicability of the proposed framework through the case of halal supply chain management (HSCM).

The proposed framework is using the capabilities of the neutrosophic number which can handle uncertain, vague and incomplete information. Initially, the risk related to the HSC is identified through a literature review and expert’s input. Further, the probability and impact of each HSM-related risk are assessed using experts’ input through linguistic terms. These linguistic values are transformed into single-value trapezoidal neutrosophic numbers (SVTNNs). Finally, the severity of each HSM-related risk is determined through the multiplication of the probability and impact of each risk and prioritised the risks based on their severity.

A comprehensive risk assessment framework is developed that could be used under uncertainty. Initially, 16 risks are identified related to the HSM. Further, the identified risks are prioritised using the severity of the risks. The high-priority risk is “raw material status”, “raw material wholesomeness” and “origin of raw material” while “information integrity” and “people integrity” are low-priority risks.

HSM risk can be effectively assessed through the proposed framework. The proposed framework applied neutrosophic numbers to represent real-life situations, and it could be used for other supply chains as well.

The proposed method is effectively addressing the issue of linguistic subjectivity, inconsistent information and uncertainty in the expert’s opinion. A case study of the HSC is adopted to illustrate the efficiency and applicability of the proposed risk framework.

Circular supply chains (CSC) are particularly important for the agri-food sector, which faces strict requirements generated by increased food consumption as a consequence of world population growth, changes in lifestyle, development of consumer society and increasing health awareness. Recent disruptive factors have placed the vulnerability of agri-food supply chains in the spotlight. Therefore, the purpose of this paper was to identify the most manageable groups of risks in order to ensure the smooth operation of agri-food circular supply chains.

Seven main risk groups were evaluated in relation to nine criteria. To solve this multi-criteria decision making (MCDM) problem, a novel MCDM model, which integrates the best-worst method (BWM) and the COmprehensive distance-Based RAnking (COBRA) method in a grey environment, was developed.

Three risks were singled out, namely, product features risks, logistics risks and managerial risks. The obtained risks are those whose management would create the most positive effects for the stakeholders and help them achieve their primary goals regarding the circularity of agri-food supply chains.

This study investigates the main characteristics of the CSC in the agri-food sector, identifies, simultaneously explores and ranks all main risk groups associated with them and expands the possibilities for solving these kinds of problems by developing a novel MCDM model. It also identifies the most significant risks, both for individual stakeholders and for all stakeholder groups together.

Micro, small and medium-sized enterprises (MSMEs) are vital for economic growth in developing countries. Yet, little research has explored the link between Islamic principles and MSME performance, especially in Uganda. This study aims to investigate the relationship between Islamic financial principles and MSMEs’ performance in Makindye Division Kampala – Uganda.

This study used a correlational research design involving 86 respondents from 30 MSMEs between January and May 2023. Data collected through questionnaires was analyzed with Statistical Package for Social Sciences, examining three independent variables: ethicality, Halal investment and prohibition of riba, in relation to MSME performance.

The results revealed significant relationships between these variables and MSME performance. Prohibition of riba (r = 0.296, n = 86, p = 0.006), Halal investments (r = 0.308, n = 86, p = 0.004) and ethical principles (r = 0.283, n = 86, p = 0.008) all exhibited a statistically significant relationship. Regression analysis with R = 0.405, R² = 0.164 and adjusted R² = 0.134 indicated that all hypothesized variables were significant predictors of MSME performance. Based on findings, this study rejected the null hypothesis, confirming a moderately positive and significant relationship between Islamic financial principles and MSME performance.

This study underscores the importance of active involvement from key stakeholders such as the Uganda Halal Bureau, Uganda Muslim Supreme Council, Islamic financial institutions and government agencies in integrating robust support mechanisms for MSMEs into their strategic frameworks. Such efforts could enhance Uganda’s economic landscape, aligning with the experiences of Malaysia and Indonesia in leveraging Islamic principles for economic growth.

This paper aims to present a review and analysis of the literature on halal services over 25 years. The number of publications on halal services has increased over the years in the fields of business, management and economic research; however, the topic has been discussed less comprehensively in relation to bibliometric analysis.

This study was conducted using review and bibliometric analysis. In total, 346 articles were extracted using a modified Preferred Reporting Items for Systematic Review and Meta-Analyses procedure, and 176 documents were eliminated because they were not within the scope of the Halal Services topic. Finally, 170 articles were analyzed using the Biblioshiny-Bibliometrix R package.

Research on halal services has grown steadily over the past 25 years. Most studies were conducted in Muslim countries; however, some non-Muslim countries, such as the United Kingdom and China, also contributed to the topic of halal services. Thematic analysis revealed that most halal services papers are categorized under the “Niche Theme” or the “Basic Theme.”

This study contributes by providing future researchers with knowledge and information on knowledge structures and state-of-the-art halal services. This study also provides insights into the development of novel ideas that may contribute to expanding the research on halal services worldwide.

This study provides a comprehensive analysis of halal services research using bibliometric analysis. Through this method, this study attempts to summarize the trends in halal service research over 25 years, which may suggest future research directions into halal services.

This study reviews and critiques the halal food literature, a growing field of research. In addition, the authors classify the significant themes in this research stream, outline opportunities for future research directions and offer a future research agenda.

A sample of 221 scholarly articles published from 1997 to 2020 was investigated using the structured literature review method of Massaro et al. (2016). The authors used the bibliometrix R-package and VOSviewer software to mine information about journals, articles, authors, citations, keywords and countries.

The analysis reveals five research clusters: halal food and the role of certifications, halal food and awareness, halal food production and quality, halal food in tourism management and halal food and the supply chain. The primary research flow comes from Asia. However, collaborations are also emerging in other continents. In addition, scholars should consider stressing the links among halal food and sustainability, innovation and technology.

The study analyses this field from a broad perspective, but only considers articles published in the Scopus database. Future research could extend the research methodologies used by, for example, considering mixed method analysis.

Despite several studies in the field, no studies have thus far reviewed the literature on halal food to the best of the authors' knowledge. Hence, the presented analysis, using pioneering methods considering sustainability and innovation as priorities, provides a starting point for future research.

This study aims to develop a measurement model of the halal supply chain resilience (HSCRES) index, which represents the capability of the supply chain (SC) to handle disruption caused by halal risks. A case study is conducted to apply the HSCRES index in the halal chicken SC in Yogyakarta, Indonesia, to test the proposed methodology.

A literature synthesis was conducted to establish the main capability and vulnerability factors and their relevant indicators. The indicators were validated using the confirmatory factor analysis approach. Then, applying an analytical hierarchy process involving ten experts – practitioners and academicians – the weight of each indicator was obtained. A survey of 20 employees of slaughterhouses, 35 sellers and 100 consumers was conducted to obtain the value of each indicator. Finally, the HSCRES index was calculated by comparing the total weighted capability value to vulnerability.

The results revealed that the resilience of halal chicken SC in Yogyakarta is at a good level, with an index of 3.459, and “halal team” is the most significant indicator. The findings also revealed several capabilities that need improvement, including dedicated halal facilities, employees’ halal competence and halal regulation. However, the lack of a halal certification board, lack of management commitment and packaging contamination were found as vulnerability indicators that need to be reduced.

The case of this study is limited to the halal chicken SC in Yogyakarta, Indonesia. As a consequence, the obtained results are limited to a specific context. The application of this method to different areas and objects enables the establishment of different capability and vulnerability indicators.

The halal resilience measurement model offers a comprehensive understanding of the strengths and weaknesses of the HSC. The findings can help stakeholders improve preparedness for halal risks, deal with halal risks better and recover more quickly. Measuring the HSCRES index can be particularly useful for policymakers in developing evidence-based strategies to increase HSCRES.

The current study is the first to define and classify the contributing halal resilience attributes and also to calculate the halal resilience index.

The fresh food supply chain industry faces significant challenges in risk management because of the complexity, immature development and unpredictable external environment of imported fresh food supply chains (IFFSCs). This study aims to identify specific risk factors in IFFSCs, demonstrate how these risks are transmitted within the system and provide an analytical framework for managing these risks.

A total of 15 risk factors for IFFSCs through extensive literature review and expert consultation are identified and classified into seven levels using interpretive structural modeling (ISM) to demonstrate the risk transmission path. Fuzzy Matrice d’Impacts Croises-Multiplication Appliance Classement (MICMAC) analysis is then used to analyze the role of each factor.

The interactions of the 15 identified risk factors of IFFSCs, classified into seven levels, are visualized using ISM. The fuzzy MICMAC analysis classifies the factors into four groups, namely, dependent, independent, linkage and autonomous factors, and identifies the relatively critical risk factors in the system.

The findings of this research provide a clear framework for enterprises operating in IFFSCs to understand the specific risks they may face and how these risks interact within the system. The fuzzy MICMAC analysis also classifies and highlights critical risk factors in the system to facilitate the formulation of appropriate mitigation measures.

This study provides enterprises in IFFSCs with a comprehensive understanding of how the risks can be effectively managed and a basis for further exploration. The theoretical model constructed is also a new effort to address the issues of risk in IFFSCs. The ISM and the fuzzy MICMAC analysis offer clear insights for researchers and enterprises to grasp complex concepts.
