Globally manufacturing organizations are implementing operational excellence (OPEX) projects to improve their long-term sustainability and competitive advantage. This research analyzes the critical success factors (CSFs) for implementing OPEX initiatives in manufacturing organizations through the utilization of a meta-analysis technique. Thirty studies were found to be relevant for the meta-analysis. The findings of the study suggest that OPEX implementation in manufacturing organizations is positively and strongly influenced by employee involvement, training and education, management commitment and involvement, and required resources to implement operational excellence. Further, OPEX is moderately influenced by leadership, project prioritization and selection, organizational culture, effective communication, customer relation, supplier relation, performance management and reward system, and teamwork. The findings also suggest that four moderators, namely location of the study, size of the firm, topic of the study, and publication year of the study also have a significant positive relationship for all of the CSFs. A comprehensive study of the CSFs for OPEX initiatives becomes imperative in this context. This research provides a better understanding of CSFs leading to successful OPEX implementation in a manufacturing environment and contributes to the body of knowledge for the OPEX research and practitioner community, especially for OPEX deployment in non-manufacturing sectors.

Purpose: The goal of this research is to find the components that can inspire people to reduce food waste at household consumer level. The components were created by combining the theory of planned behaviour (TPB), theory of interpersonal behaviour (TIB) and motivation opportunity ability (MOA) model.Design/methodology/approach: The study is based on the content analysis, which identifies the motivating factors for food waste reduction at the consumer household level. A total of 12 motivating factors are identified across extensive literature reviews along with opinions of experts. Then, the recognized motivating factors are analysed for causal interrelationship using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach. Data were collected from 95 experts, selected using purposive sampling, through a questionnaire survey.Findings: A total of 95 household experts expressed their views on food waste reduction motivation factors, and a decision matrix has been developed based on that. Then, opinions are analysed using the DEMATEL approach, and it was found that “perceived behavioural control (PBC)” is the most influential motivating factor for food reduction at the household consumer level. Results also showed that “knowledge and skills about proper food management at home” are the least affected factor among the others.Practical implications: Minimizing food wastes at the consumer and household level can provide the benefits to both people and environment in multiple ways. The problem of food waste necessitates a multifaceted response, and this study aims to address consumers' motivation and capabilities to lessen food waste behaviour. Since the benefits of minimizing food wastes have often remained untapped and neglected, educational efforts should be used by policymakers to enhance household awareness of food waste.Social implications: The present study contributes to the inadequate research on household food waste in India and is expected to facilitate sustainable consumption.Originality/value: Food waste management is particularly difficult for developing countries, like India, which have little resources and are environmentally vulnerable. Not only is there a dearth of study on household food waste, but most of the research has been conducted in developed economies. Also, a novel applied method has been utilized in this study.

Purpose: This study aims to enhance freight logistics by overcoming barriers and driving sustainable growth through an integrated approach. It focuses on the critical role of efficient freight logistics in sustaining economic growth and addresses the challenges hindering the sector’s efficiency. Design/methodology/approach: The research employs the grey Delphi method for a comprehensive literature review and expert evaluation to identify significant barriers in India’s freight logistics sector. Subsequently, the grey decision-making trial and evaluation laboratory (DEMATEL) method establishes causal relationships among these barriers to provide insights into their interconnectedness. Findings: The findings of the study highlight the importance of addressing these barriers through sustainable strategies and innovative solutions. The study recommends the adoption of green transportation technologies, collaborative efforts among stakeholders and the development of modern logistics facilities. By mitigating the adverse effects of logistics operations on the environment and society, these strategies aim to improve overall efficiency and competitiveness in the freight logistics sector. Research limitations/implications: This study is primarily based on feedback from ten seasoned experts; however, incorporating input from a broader range of experts would provide deeper insights and perspectives. Originality/value: This study offers a comprehensive analysis of barriers and opportunities for sustainable growth in India’s freight logistics sector. The study contributes valuable evidence-based insights and practical recommendations, serving as a guide for policymakers, industry stakeholders and practitioners seeking to enhance the efficiency and competitiveness of the country’s freight logistics operations.

The Internet’s meteoric rise in popularity has led to the growing importance of the quality of online services in numerous industries, including the rapidly expanding tourism industry. Accordingly, this study aims to ascertain the leading attributes of selected travel websites based on sustainable e-service quality. This study was conducted in four phases. In phase I, the key drivers of sustainable e-service quality (SESQ) were identified from a literature review and expert opinions and then categorized and validated using the EFA technique based on the responses of 100 respondents in phase II. Phase III was performed to determine the priority weightage of the identified and validated SESQ drivers using AHP, whereas in phase IV, the five most popular travel websites in India were ranked based on the SESQ drivers using the TOPSIS method. A case study is presented in this paper to demonstrate the applicability of the proposed framework. Finally, a sensitivity analysis was conducted to determine the robustness of the results. The findings of the study revealed that security, hedonic value, and efficiency were the most important drivers of SESQ that influenced customers’ selection of travel websites, and makemytrip.com was the most preferred travel website by customers.

Recently, hoteliers focussed shifts on green practices because of sustainable goals. Also, guests are more health-conscious nowadays. Hence, biophilic elements and designs attract hoteliers and guests, and selecting the best biophilic elements/designs is one of the most important decision-making problems in the lodging industry. This study investigates the various biophilic elements/designs as main criteria and sub-criteria and evaluates them through the trapezoidal interval type-2 fuzzy analytic hierarchy process technique. Once the main biophilic elements and sub-biophilic elements for hotel selection are identified, the hierarchy structure has been designed. Then the weights are calculated using the interval type-2 fuzzy analytic hierarchy process technique. Finally, the biophilic element/design with the highest priority weight is selected as the most preferred by the guests. The robustness of the results is checked by comparing them with the results of the crisp analytic hierarchy process and sensitivity analysis. The findings of the study will help the decision-makers of the lodging industry in making more efficient and effective strategies.
