Because of their lightweight, friendly processing and acoustic insulation, green composites have been used widely ranging from aerospace sector to household applications. The end-of-life concern with many polymeric composites has also limited their application spectrum. The green composites not only replace the traditional materials such as steel and wood but also challenge certain nonbiodegradable polymer composites. The present research initiative aims at highlighting the issues and challenges in the development and characterization of poly lactic acid–based green composites. A few of these important composites and their mechanical properties (tensile, compressive, flexural, and impact strength) have been reported in this study. The focus is the identification of the possible areas for their novel applications. A study has been conducted to categorize the various types of green composites on the basis of their physical, chemical, and mechanical characteristics.

The cost effective services, delivery mode and delivery time make the governance friendly to the citizens. But the conflicting and lengthy house's address system in India causes a lot of delays in services delivery. A house or building address could be used for various purposes like postal services, courier services, logistics services delivery, meetings, party venue etc. A high degree of failed service deliveries provide a gap to digitize the house address system to deliver accurate and faster services to the citizens. The paper proposes a conceptual method to digitize the house address system which may be stored electronically into a centralized database to reduce the time consuming process of writing and storing a lengthy address repeatedly for delivering the various services. The paper also explores the possibilities of how this digitized address could be integrated with the aadhaar database system to make it more potentially applied in terms of citizens' oriented applications and services. The digitized address would contribute significantly to transform India into a digitally empowered society and knowledge economy.

Natural calamities include earthquakes, tsunamis, floods, cyclones, volcanic eruptions, fire and epidemics while conflicts, wars, violence and accidents are considered man-made emergencies. The traditional components like shelter, food, water and health are often on high priorities in life-saving assistance, while providing education is often ignored in humanitarian crises. The young people and children may be at risk of violence, sexual abuse, child labor, mobilize by armed groups or other life-threatening activities during emergencies. Education programs in emergency can help children or youth to overcome from disaster situation like fear, loss, stress, violence and to learn tolerance, risk reduction and life skills. Any type of emergency usually causes disturbances and irregularities in education systems. A smart education system may play a leading role to restore the academic cycles for such students during the emergencies. The smart education system could be described as a learning environment where rich and interactive knowledge is shared among different stakeholders with the integration of smart devices and technology. The paper explores the possible new technological solutions for providing education which could be employed in a faster and effective manner during such situations. To make any program successful, a well-defined strategic planning is also required. Hence, the role of governance is crucial to plan, implement and monitor such programs. The study proposes a conceptual framework explaining smart learning solutions and governance role to implement such solutions to fulfill the educational needs of the emergency-affected children and adolescents to overcome from future threats to live and their livelihoods.

Strategic decision-makers need comprehensive models that can guide them in efficient decision-making to increase the profitability of the entire forward and return chain. Therefore, determination of a near optimal design configuration, which includes the environmental, economical and technological capability factors, is important in strategic decision-making effort that affect the profitability of the closed loop supply chain. In this paper, we adopted an improved system dynamics methodology to tackle strategic issues that affect various performance measures, like market, time/cost, environment etc., for closed loop supply chains. After studying real life implementation issues in CLSC design, we presented guidelines for the PBM (Participative Business Modeling) methodology and presented its extension for the strategic dynamic system modeling of return chains. Finally, we demonstrated the measurement of operational performance by extending SD (system dynamic) application to closed loop supply chain management.

This leads to complex situations where decisions have to be taken within a short time and among several alternatives-often without the human intervention. This paper considers flexible system as a mixed model flexible flow line, where 'n' independent jobs are required to be processed on 'm' different machines, where all the jobs have the same processing order on the machines. Here the objective is to find the ordering of the jobs on the machines that minimizes the make-span. Above objective can be achieved through evolutionary based heuristic of Genetic Algorithm (GA) on the flow line scheduling problem. The advantage of the GA approach here is the ease with which it can handle constraints and objectives;, making it easy to adapt the GA scheduler to the particular requirements of a very wide range of possible line scheduling problem. The proposed architecture has been developed to depict the application of genetic algorithms to optimize production schedules in a flexible flow line system representing a flexible system. Results show that the implementation of the genetic algorithm is very effective as compared to standard sequencing rules like shortest processing time, total processing time, etc. and at the same time easy to use. Finally this paper intends to discuss some of these interesting results with a focus on application of leadtime reduction in an interesting flexible system like RES (Reverse Enterprise System).

The port system has significant contributions to the fluent operations of the freight transportation system. With the increase in transport demand, the port faces multiple complexities such as lower utilization of resources, capacity issues, etc. The forecasting of container traffic at the port would help the port planning team and managers analyze the port system's infrastructural investment and optimization. In this study, the annual data of the past 20 years (1999-2019) of container traffic in TEUs at three Indian major ports have been considered. The grey forecasting model and Auto-Regressive Integrated Moving Average (ARIMA) model is developed to analyze the container traffic data. Further, the Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE) is used to test the model's accuracy. The results of the study show that both models are fit to forecast the container traffic data. Precisely, the grey forecasting model fits better than ARIMA for two ports Tuticorin and Cochin, with MAPE of 10.52% & 4.80%, respectively. The findings of this study would guide the practitioners and planning managers in decision-making related to port optimization.
