This paper discuss the application of artificial neural network-based algorithms to identify different types of faults in a power transformer, particularly using DGA (Dissolved Gas Analysis) test. The analysis of Random Neural Network (RNN) using Levenberg-Marquardt (LM) and Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithms has been done using the data of dissolved gases of power transformers collected from Punjab State Transmission Corporation Ltd.(PSTCL), Ludhiana, India. Sorting of the preprocessed data have been done using dimensionality reduction technique, i.e., principal component analysis. The sorted data is used as inputs to the Random Neural Networks (RNN) classifier. It has been seen from the results obtained that BFGS has better performance for the diagnosis of fault in transformer as compared to LM.
Business continuity in disruptions like the COVID-19 pandemic involves sustainable supply chain management (SSCM) with limited resources and risks for the well-being and prosperity of stakeholders and customers involved with limited environmental effects. The purpose of the paper is to outline enablers in customer engagement that supports SSCM in times of disruption like the COVID-19 pandemic. This research uses an extensive literature review followed by academic and industry practitioners' opinions to identify customer engagement enablers in SSCM for business continuity. Hybrid stepwise weight assessment ratio analysis (SWARA) and rough set numbers rank customer engagement enablers that support SSCM in disruption. The research builds on stakeholder theory and the sustainability framework for economic performance through non-economic aspects. The research concludes that the focus on agility for target customers through collaboration and information sharing in SSCM will support business continuity. It shall support decision-making in the supply chain in uncertainties. Engagement with stakeholders leads to focused execution in response to customer demand through faster communication and crucial information sharing, thus eliminating bottlenecks for business continuity.
Sustainability has become a mandatory strategy for survival on the planet. Sustainable development is an imperative for survival and growth for nations, peoples and the organisations. The study embraces the sustainability initiatives of Global and Small/Medium enterprises (SME) working in India. Data was collected for the study using a questionnaire. Mid-senior level executives were contacted for their take on sustainability initiatives by their organisations in India. The responses were collected both from globally operating organisations and SME in India. The summarised data was analysed to arrive at the conclusions. The study indicates that global organisations are operating at global scale in corporate sustainability programs for competitive advantage, to mitigate risk, for building a brand, and to regulate the complexity of global supply chains for business growth to ensure an enhanced market share/customer growth. The SMEs in India are found at a nascent stage with respect to sustainability and are only involved in activities necessary for their survival. Incorporating sustainability initiatives in the business practices of SME will need awareness and policy frame. On the other hand, the global organisations have a long way to go to create appreciable impact on the planet via their sustainability efforts. However, changes of responsible product, processes and global supply chain designs are being incorporated in their culture. These initiatives will need further push through governance and policy announcements at a regional and country level for far reaching impact. And for emerging countries like India they can be leaders in sustainability efforts for other Indian organisations particularly SME to follow sustainability based practices.
Sustainability as a strategy has been incorporated in decision-making process at General Motors -an automotive manufacturing company. It has helped General Motors to overcome financial crisis. In today's environment, incorporation of sustainability factors particularly in supply chain management is critically important when governments all over the world are working to arrest climate change and reduce emission levels. Therefore, sustainability incorporation at an organisational level is a way forward. Case study was undertaken via a questionnaire to collect and evaluate the decision criteria from the middle and top level executives of General Motors. The authors also attempted to examine sustainability reports of the General Motors formulated using GRI guidelines. Study concludes that getting sustainability incorporated into DNA of a company requires top management commitment and is associated with organisations where there is history of societal, community work and responsible business practices. It helped General Motors to write off debt and come out of bankruptcy. The study is also relevant for manufacturing organisations in other sectors as the research instrument is developed using GRI guidelines. The research instrument and study can support researchers and practitioners to adopt sustainability-based strategy and practices for responsible development which is sustainable.
