Fly ash has been recognized as hazardous material causing air, soil and water pollution. Fly ash a ‘waste by-product’ of electricity generation from power plants (coal-based thermal) has an estimated annual production of approximately two hundred million tons. In-spite of many problems associated (like land requirement for disposal, toxicity to groundwater, handling issues etc.); we have started treating fly ash as a resource material. Present research addresses usage of fly ash in roads & bridges and embankments. In the present study, an attempt has been made to recognize and analyze comprehensively key elements and sub-elements of program implementation of fly ash usage and further to segregate Critical factors (CFs) of usage of fly ash in roads & bridges and embankments. Eight relevant CFs have been recognized for usage of fly ash in roads & bridges; and ten CFs for the usage of fly ash in embankments. Thereafter, Interpretive Structural Modeling (ISM) approach has been applied on these CFs and two models of driver CFs, linkage CFs and driven CFs have been obtained. Appropriate discussions along-with MICMAC analysis in the light of important elements and sub-elements have helped to present managerial implications useful for stakeholders. © 2016 Elsevier Ltd

Knowledge management (KM) has been increasingly recognised as an emerging field of research in the last few years. The present paper addresses the need of exploring the field of knowledge management. The study presented is an attempt towards identifying important critical success factors (CSFs) of knowledge management relevant to the Indian industry. Literature review and subsequent brainstorming sessions with experts (both from academia and industry) have suggested six most important CSFs. An interpretive structural modelling (ISM)-based model has been presented on these identified CSF. Further, these CSFs have been classified using MICMAC analysis. Contextual relationships among CSFs have also been established using experts' opinions. This paper may help researcher and practicing managers to understand interaction among these CSFs and its overall effect on successful KM implementation. Further, this understanding may be helpful in framing the policies and strategies to manage KM processes and activities. Copyright © 2015 Inderscience Enterprises Ltd.

Productivity as a measure for output is important to industry and academia. In this research, factors to enhance productivity have been identified from the literature by reviewing various international and national sources to explore this evergreen field of research that is “productivity,” which has always been an increasingly interesting area of research for researchers over decades or perhaps over centuries. In total, 15 number of factors have been identified to enhance productivity. Analytic hierarchy process approach has been appropriately chosen to rank these factors because of its simplicity and effectiveness. The tool has been used by taking perception of experts from the Indian manufacturing industry. Positive attitude and involvement of management, proactive employees, and good working conditions have been ranked as top three factors as per the experts’ opinion. The ranking of factors to enhance productivity, categorization of the factors into four perspectives, and hierarchy of perspective and action plan as a final outcome of the paper may help academia and operations managers toward effective management of “operations and production activities of firms/supply chains”. © 2016 The Author(s).

Renewable and Sustainable Energy Reviews | Year: 2015

Rapidly increasing energy demand and growing concern about economic and environmental consequences call for renewable/sustainable energy technologies? adoption in India. Renewable/sustainable energy technologies have faced a number of constraints that have affected their rate of adoption. In this paper an attempt has been made to identify and rank the major barriers in the adoption of 'renewable and green' energy technologies in the Indian context. Twenty-eight barriers have been identified from an extensive literature review. These identified barriers have been categorized into seven dimensions of barriers, i.e. Economical & Financial; Market; Awareness & Information; Technical; Ecological and Geographical; Cultural & Behavioral; and Political & Government Issues. Analytical Hierarchy Process (AHP) technique has been utilized for ranking of barriers to adopt renewable/sustainable technologies in the Indian context. All pair comparisons in AHP have been made based on experts' opinions (selected from academia and industry). Sensitivity analysis has also been made to investigate the priority ranking stability of barriers to adopt renewable/sustainable technologies in the Indian context. This paper may help practitioners, regulators and academician focus their future efforts in adoption of 'renewable/sustainable energy technologies' in India. Further, this understanding may be helpful in framing the policies and strategies towards adoption of renewable/sustainable energy technologies. © 2014 Elsevier Ltd. All rights reserved.

Global electricity demands are increasing at rapid pace. Energy supply, their usage and technologies involved need to be more economical, environment friendly and socially sustainable. Efforts are being done all over the globe to reduce this greenhouse effect; and renewable energy technologies to combat climate changes, which require extensive changes to the current electricity generation and distribution systems. To meet this goal, it is required to optimize the grid operations and available resources to meet the ever increasing energy demands in an efficient, effective and environment sustainable way. It has been found that smart grid technologies have not been so popular due to some obstacles that are hindering its maturation and rapid deployment. An attempt has been made to identify and analyze the barriers to implement smart grid technologies adoption. Twelve relevant barriers towards implementation of smart grid technologies have been identified from extensive literature review and duly validated with experts (from academia and industry) opinions. Also, valuable experts opinions have been utilized to identify contextual relationships among these important barriers and a hierarchical model has been developed based on Interpretive Structural Modeling methodology. Matrice dImpacts Croises-Multipication Appliqué an Classment (MICMAC) analysis has also been used to: classify the barriers based upon dependence and driving power; and validate developed ISM based model. "Lack of Regulatory Framework" barrier has been identified as driver or independent level barrier i.e. most important bottom level barrier hindering adoption of smart grid technologies. The developed structured model will help to understand interrelationships and interdependencies among the identified barriers to implement smart grid technologies. Different solutions for handling these identified barriers have also been suggested in the paper. Organizations involved in power generation and distribution may be benefited by understanding of these barriers, their interactions and suggested mitigation solutions towards effective adoption of smart grid technologies. © 2014 Elsevier Ltd.

Technology Transfer (TT) has been identified as an important approach to achieve competitive advantage over other organisations. The objective of this paper is to contribute to the existing literature by comprehensively reviewing and identifying enablers and barriers to implement TT. In this paper, background of TT and major contributions given by various researchers in the field of TT has been presented. The 'factors to enable TT implementation successfully (referred to as enablers)' and 'barriers to hinder this process of TT implementation' have been identified. Based upon extensive literature review, conceptual model has been put forward. Enablers and barriers to implement TT need to be addressed and examined critically. This review will surely help researchers and practitioners in better understanding towards implementation of TT in most effective way. © 2014 Inderscience Enterprises Ltd.

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 developing a hierarchical model of barriers in implementing the GLSPD process in the automobile sector of India. A nine-level structural model has been deduced after application of the ISM technique, which shows ‘Competition and Uncertainty’ as the topmost output of the model and ‘Lack of Total Top Management Commitment’ as the bottom-level input to other barriers of the model. Further, MICMAC analysis has been also done to classify these barriers for better understanding; seven barriers are identified as driver barriers, nine as dependent, five barriers as linkage and no barrier as autonomous. An analysis of interdependence and interactions among these barriers may help supply chain managers reach a better understanding of barriers. Thus, managers may be helped in prioritising and managing barriers in order to gain a competitive advantage from GLS concept implementation in product development. © 2016 Informa UK Limited, trading as Taylor & Francis Group
