This study contemplates the distribution of products in a supply chain where the demand is sensitive to effort and price. Using a framework of game theory, the analysis highlights the impact of a manufacturer announcing a returns policy to the retailer when there is competition. Comparative analysis of offering a returns contract under competition with respect to no returns contract provides a better understanding about the repercussions and related facts on offering returns policy. Analytical results show that introducing returns policy under a monopolistic environment does not have an impact on the sales and it remains the same as in the case of no returns policy. On the other hand, introducing returns policy in duopolistic competition increases the manufacturer's profit for the same wholesale price. Journal: Int.

SVM is one of the most popular supervised machine learning algorithms and uses kernel function to classify data when the data points are nonlinearly separable. In this paper, we have proposed a new Kernel function called Jaccard dissimilarity Kernel functions where the distance between the two binary vectors is classified based on principle of Jaccard coefficient. In our study, we used this Jaccard Kernel function to classify the opinions of the recent Bollywood movie reviews in to positive and negative. Journal: Int.

Metal matrix composites have emerged as remarkable materials due to their superior characteristics when compared to other matrix composites. The most promising lightweight materials are composed of aluminium alloys, which are utilised in the marine, aerospace, and automotive industries, but their use is limited due to their average strength and moderate wear resistance. In terms of wear resistance, AMCs beat their monolithic counterparts that are unreinforced. Stir casting was used to produce aluminium matrix composites made of 413 aluminium alloys with particulate fly ash reinforcements weighing 3%, 6%, and 9%. Wear tests were conducted in pin-on-disc wear tester following ASTM Standard G99-05 guidelines. The goal is to explore the effects of sliding speed, load, sliding distance, and reinforcing weight percentage on coefficient of friction and specific wear rate using ANOVA and grey relational analysis. Sliding distance (18.48%), load (17.39%) are the parameters which have extreme significance on composites' GRG followed by sliding speed (10.33%) and reinforcement (4.35%). By using grey relational analysis, wear behaviour can be predicted successfully. Journal: Int.

To achieve this objective, the data were collected from 15 field experts and 559 employees working in the manufacturing industries of India. The fuzzy AHP technique prioritised the factors and structural equation modelling tested the proposed hypothesised relationships. The confirmatory factor analysis validates that leader-member exchange, procedural justice, and employee engagement are essential factors affecting organisational citizenship behaviour. Further, the results of fuzzy AHP show that leader-member exchange ranked first, followed by procedural justice and employee engagement. The structural equation modelling result shows that perceived procedural justice and leader-member exchange positively impact employee engagement. The results further show that employee engagement has a positive impact on organisational citizenship behaviour. The implications of the study can be used by the manufacturing industry as a benchmark for increasing the extra-role behaviour among the employees. Journal: Int.

LSS, which is an integration of Lean and Six Sigma, has helped decrease various non-value-added activities, including accidents. This research paper discusses the implementation of LSS methodology using 'define, measure, analyse, improve, control' (DMAIC) to reduce accidents in a particular manufacturing unit into consideration. A framework of the LSS-DMAIC approach was proposed to reduce accidents, improve key metrics and improve the overall safety culture. The techniques used were brainstorming, the cause-and-effect diagram, and Pareto analysis. Two sample T-test was used to authenticate the results. The study's primary finding was the successful and effective implementation of the LSS framework in the manufacturing unit. As a result of the exercise, accidents that are non-value-added activities were reduced. The study is novel in nature, not only for theoretical implications, but also for the practical approach applied to the manufacturing units. Journal: Int.

The researchers also wanted to determine if MWAE leads to word of mouth (WOM) recommendation. Previous research indicates that customisation, knowledge, relative advantage and compatibility could be possible antecedents of MWAE. Further, the mediating effects of trust and mobile wallet app usage in the relationship between MWAE and WOM recommendation were also examined. The findings of this study revealed that compatibility and the relative advantage positively influences MWAE. The result supported a sequential mediation model between MEAE, and WOM recommendation through the mediators trust and mobile wallet app usage. Customisation and knowledge do not moderate the relationship between compatibility and MWAE and relative advantage and MWAE. The entire users were segmented into three clusters based on the factors influencing the MWAE. The findings show that all the factors significantly differ across all three segments. Cluster 2 respondents significantly influence the MWAE that further leads to the WOM recommendations. Theoretical and practical implications are discussed. Future research directions and limitations have been suggested. Journal: Int.

To combat COVID-19, scientists developed vaccines in record time. Without proper vaccine distribution, the country would suffer from low coverage rates and the virus would continue to spread. We are losing over 3,000 lives each day to COVID-19; this means a single day of delay in the distribution of vaccine is costing thousands of innocent lives. In this paper we have formulated a distribution model using mixed integer programming (MIP) that maximises the number of people vaccinated, minimises the cost of transportation over the entire network while ensuring widespread access.

It is important to establish an effective technology for the efficacious machining of MMCs because of its future widespread use. The drilling of LM5/ZrO<SUB align="right"><SMALL>2</SMALL></SUB> composites employs Taguchi technique to find the optimum machining parameters to minimise surface roughness. The stir casting process is used to make a novel composite prepared by combining LM5 aluminium alloy with Zirconia with three distinct weight percentages (3, 6 and 9). In the produced composites, the effect of input parameters such as spindle speed, feed rate, drill material and reinforcement percentage on surface roughness was studied using L<SUB align="right"><SMALL>27</SMALL></SUB> orthogonal array by conducting drilling operation in CNC machine. The research work was performed using the Taguchi's signal-to-noise ratio approach. Response graphs were used to evaluate parametric effects. Analysis of variance (ANOVA) was accompanied to find the related variables and assess their influence on the individualities of the response. Feed rate and Spindle speed are the most influential input parameters to achieve minimal surface roughness. Journal: Int.

The authors identified 12 motivators through an extensive literature review and an expert survey. This study adopted the interpretive structural modelling (ISM) technique to assess the interrelationship among the various motivators of entrepreneurial aspirations in the context of university students in India. The present study suggests that strong self-efficacy, need for achievement and entrepreneurship education are the prime motivators of entrepreneurial aspiration among university students in India. On the other hand, high motivation, propensity to create new business, entrepreneurship funding, and entrepreneur identity creation are the dependent motivators and enjoy high dependence and weak driving power. This study provides valuable insights to policymakers and universities on ways to focus on variables that are deemed critical for developing entrepreneurial aspirations among students. Journal: Int.

The study found no significant difference between the expected and actual benefits of digital payment apps. Qualification and gender were found to be significant factors for the adoption of digital payment apps. Convenient, time-saving, and no need to carry cash are the main factors for adopting and using the digital payment app. Lack of trust, risk associated with it, and unavailability of the technical equipment are the reasons found by the study for not using digital payment apps. The study suggests ways for companies to build the trust of their customers to adopt digital payment apps. Journal: Int.

Supply chain performance is playing a critical role and is becoming a key component in creating additional value to the organisation, especially in the current era of globalisation. This study reflects the role of supply chain performance on global value creation, where leading e-commerce sites are considered based on supply chain performance. The partial least square-structural modelling was used to test the proposed framework. Factors like 'supply chain flexibility', 'risk management capabilities', and 'customer relationship management' emerged to be the most important and crucial ones. Further studies have been conducted involving various sectors by considering the different states of affairs of particular times. Journal: Int.
