Speech Title: Environmental Friendly Supply Chains under Carbon Cap Scheme
Speech Abstract: Due to increasing environmental concerns and stricter legislations, we take a fresh look at the impact of logistics on the environment. The study investigates the trade-off between transportation cost and carbon emission in freight consolidation and containerization problem. We determine the types and quantities of containers and trucks that will result in an environmental friendly supply chain, and then apply the model in a real-world business case. The objective of the talk is to investigate how carbon cap scheme can sustain environment. We will discuss the background and motivation and the problem we are facing due to increasing environment issues, such as carbon emissions and climate change. Then research problem and scopes will be developed in a framework. Literature review will be done to survey the current research regarding sustainable supply chains under carbon cap scheme. Conclusion remarks and managerial insights will be provided at the end.

Speech Title: Investigation on the Wire Electro Discharge Machining Behaviour of Alumino Silicate Particles Reinforced AA6061 Alloy Composite Prepared by Compocasting Route
Speech Abstract: Metal matrix composites have tremendously increasing demand in thermal management areas, as well as in sports and recreation. Aluminium based Metal matrix composites (AMC) are gaining significant interest in high-tech structural and functional applications including aerospace, defence, automotive and sports equipment manufacturing industries, due to their interesting mechanical and material properties such as high strength, high stiffness, damping capacity, reduced density and improved abrasion and wear resistance capacity compared to unreinforced alloy. However increasing demand of AMCs creates challenges to make mass production of AMCs at low fabrication cost. As a result, there has been gaining significant interest in reinforcements containing low density and low cost such as fly ash and natural minerals. Currently, there are several fabrication methods are used to synthesize AMCs reinforced with different kinds of ceramic particles .The mechanical and the tribological behavior of the AMCs are influenced by the processing method. Enhancement of AMC properties requires the successful incorporation of ceramic particles into the aluminum matrix and obtaining good bonding between them. Among all other processing routes, stir casting is the most widely used liquid casting method to prepare AMCs. But wettability is the major setback in stir casting between the molten matrix and the ceramic particle. Several techniques have been attempted to improve the wettability by many researcher. These accessory techniques associated with the stir casting process has been increased the overall cost of fabrication. Therefore, in the present study an economic and modified stir casting method has been implemented to synthesize the hollow cenosphere fly ash particle reinforced AA6061aluminium alloys known as compo casting process. Where the alloy matrix is kept in semisolid state instead of fully molten state by controlling the casting temperature. Several researchers established that the prepared AMCs using compo casting technique has improve wettability and better distribution of ceramic particles in Al alloy matrix. However, the applications of existing MMCs are limited whereas the machinability is the major concerned. Poor machinability of the material results in poor surface finish and excessive tool wear. The influence properties that associated with the MMCs confronted a lot of challenges while machining on it. Since hardness, toughness and impact resistance of the MMCs were increasing after adding of reinforcing materials, so it’s become difficult to be machined of those composites by traditional machining processes due to the abrasive nature of the reinforced particles. Hence, electrical discharge machining (EDM) process becomes viable method that does not required any mechanical energy for removal of the material. It is also realized from the review of literature that the studies related to die sinking EDM characteristics of MMCs are reasonably extensive while compared with the finding reported on WED machining behaviours of MMCs. Hence, This work provides the contribution of understanding the effects of process variable like pulse on time(Ton), pulse off time(Toff), percentages of reinforcements(Wt.%) and wire speed(Wfeed) on the performance characteristics like cutting rate (CR), surface roughness(SR) and kerf width(KW) of compo casted cenosphere particle reinforced AA6061 alloys while machining through WDEM. Moreover, it has been reported in several studies that the EDM machining parameter also play a significant role in deciding the performance characteristics. The solution of multi response optimization problems could be done by using several optimization methods. However, the prediction of non-linear relationship obtained between the design variables and responses is still challenging in industry. It was reported that, (i) the significance of interactions and square terms of process parameters is more clearly anticipated in response surface methodology (RSM) than other approaches. (ii) RSM technique can model the performance characteristics in terms of significant process variables, their interactions and square terms, which are not provided by many other techniques. (iii) 3D response surfaces developed by RSM can help in visualizing the influence of process parameters on response in the entire domain specified. Hence, in this study the face centered central composite design (CCD) of RSM is employing for the design of experiments. The present work is confronted to investigate the microstructure of prepared MMC and WEDM studies by developing mathematical model and examine the effects of process parameters on the performance characteristics of prepared MMC using response surface methodology. Consequently, the quantitative mathematical models have been developing to study the effects of process parameter on the responses by using RSM approach. An optimal set of processing condition which yields optimum performance characteristics of the WED machined AMCs were obtained by desirability approach and Grey based hybrid response surface methodology.
