An integrated framework for sustainable supplier selection and evaluation in supply chains

Analysis of the driving and dependence power of barriers to adopt industry 4.0 in Indian manufacturing industry

Circular supply chain emphasizes surge in application of reuse, recycling and remanufacturing and thereby promotes the transformation of manufacturing characteristics from linear (‘take-produce-utilize-dump’) to circular model of flow of products, by-products and waste. Supply chains of manufacturing industries have become global in last few decades. Products manufactured in developing nations like India and China are being sent to developed nations for consumption in higher volumes. Developed nations have the regulatory policies, technological knowhow and modern infrastructure to adopt circular supply chain model. Their counterpart is trailing in these aspects. In literature, limited research work has been performed on identifying challenges of implementing circular supply chain management in developing nations and their contextual association. In this article, based on thorough literature review and feedback received from experts, sixteen important barriers were identified to circular supply chain management adoption in Indian context. The listed barriers were then analysed using an integrated Interpretive Structural Modelling - MICMAC approach. This study attempts to identify the contextual interactions among identified barriers and to examine their hierarchical levels in effective adoption and implementation of circular supply chain management. The findings of this research will contribute in transforming supply chains in terms of bringing economic prosperity, addressing global warming issues and generating numerous employment opportunities. Finally, some crucial policy measures and recommendations are proposed to assist managers and government bodies to adopt and manage the concepts of circular supply chains effectively in Indian context.

Ranking of drivers for integrated lean-green manufacturing for Indian manufacturing SMEs

In today’s competitive globalised business environment, production cost cutting is a primary issue before operation managers. As a research area, green lean six sigma (GLS) is proposed to have strategic importance in product development towards cutting costs, contributing to optimisation, and achieving sustainability. This research requirement has been realised to draw benefits out of three recent and involved approaches (green, lean and six sigma). In this research, an attempt has been made to address barriers in GLS product development (GLSPD) from an extensive literature review and from experts’ opinions towards developing a hierarchical model structuring these barriers. Twenty-one barriers have been identified and sorted from the review of literature and were then validated through discussions with experts. Relationships (contextual in nature) among these barriers have been realised during a brainstorming session. An interpretive structural modelling (ISM) technique has been utilised for devel...

Barriers in green lean six sigma product development process: an ISM approach

Innovation management (IM) has increasingly been identified as an important research area to consider new ideas from different perspective and to improve the outcomes of business processes. Important contributions, mostly from the last five years, in field of IM have been included in this study. A model has also been presented to show the key theme areas of IM research. Literature has been reviewed to identify seven critical success factors (categorising 49 factors); nine benefits; and three perspectives of risks (categorising 11 risks). A statistical survey has been carried out to reveal: customer’s perspective and organisation perspective as most important CSFs; long term competitive advantage and improved efficiency as most beneficial; and operational risk as most critical area in IM. Analysis of CSFs, benefits and risks will help organisations to prioritise and manage them effectively and efficiently to draw advantage from IM.

The operating principle and noise performance in AlGaN/GaN HFETs has been studied. In particular, it has been demonstrated that substrate material selection plays a great role in device performance for application point of view. Polarization induced surface states plays key role in formation of 2 DEG. Performance parameters study of device is related to noise study in devices because low frequency noise affects the device performance. Different types of noise and their possible reasons has been studied.

AlGaN/GaN HFET: Operating Principle And Noise Performance

A rapid and reproducible RP-HPLC chromatographic method has been developed for the estimation of Balsalazide in its pure form as well as in pharmaceutical formulation. Chromatography was carried out on a C18 column using a mixture of water and acetonitrile as the mobile phase at flow rate of 0.8 ml/min and detection was done at 368 nm. The retention time of the drug was 3.685. The results obtained with the proposed methods are in good agreement with labeled amounts when marketed pharmaceutical preparations are analyzed. The recovery in the present method is in the range of 99.96 - 100.6. Results obtained are found to be reproducible.

Resilience to electromagnetic jamming and its avo idance are difficult problems. It is often both har d to distinguish malicious jamming from congestion in th e broadcast regime and a challenge to conceal the a ctivity patterns of the legitimate communication protocol f rom the jammer. In the context of energy-constraine d wireless sensor networks, nodes are scheduled to maximize the common sleep duration and coordinate communication to extend their battery life. This results in well-def ined communication patterns with possibly predictab le intervals of activity that are easily detected and jammed by a s tatistical jammer. We present an anti-jamming proto col for sensor networks which eliminates spatio-temporal patterns of communication while maintaining coordinated and contention-free communication across the network. Our protocol, WisperNet, is time-synchronized and us es coordinated temporal randomization for slot schedul es and slot durations at the link layer and adapts routes to avoid jammers in the network layer. Through analysis, sim ulation and experimentation we demonstrate that WisperNet reduces the efficiency of any statistical jammer to that of a random jammer, which has the lowest cens orship-to-link utilization ratio. WisperNet has been implemented o n the FireFly senor network platform.
