Day by day, Cloud computing is becoming a very promising computing platform for various applied areas of computing including science, engineering and business. A Cloud infrastructure is consisting of multiple distributed and heterogeneous resources. The notion of a Cloud has existed in one form or another for some time now. But due to the recent advances in virtualization technologies and ICT enabled business, this concept has became more appealing today. Clouds computing aim to deliver more economical solutions to both consumers and providers. The minimization of energy consumption plays a crucial role in the context of the economical solution for computing. Energy usage in Cloud computing has yielded many other concerns like carbon emissions and system reliability. Global warming due to carbon emission is the main concern in present day computation. This paper discusses the various elements of Clouds, which contribute to the energy consumption and carbon emissions. Toward the end, this paper also discusses the solutions to minimize the carbon emission. © 2012 Praise Worthy Prize S.r.l. - All rights reserved. Source

Every decade, a revolution changes the way we use computer. A huge mainframes in the 1960s, minicomputers in the 1970s, personal computers in the 1980s, cell phones and smart phones in the last decade to the emergence of could computing in the recent years has shown the tremendous revolution in information technology spectrum. This paper will succinctly discusses the state-of -the-art cloud computing technologies and its impact on industry and academia. Emphasis also has given to the technical features of cloud development environment like the features of the programming languages used for cloud development. © 2011 PraiseWorthy Prize S.r.l. Source

Purpose – The purpose of this paper is to capture the dynamic variations in sales of a product based upon the dynamic estimation of the time series data and propose a model that imitates the price discounting and promotion strategy for a product category in a retail organization. A modest attempt has been made in the study to capture the relationship between the sales promotion, price discount and the batch procurement strategy of a particular product category to maximize sales volume and profitability. Design/methodology/approach – Time series data relating to sales have been used to model the sales estimates using moving average and proportional and derivative control; thereafter a sales forecast is generated to estimate the sales of a particular product category. This provides valuable inputs for taking lot sizing decisions regarding procurement of the products that considerably impact the sales promotion and intelligent pricing decisions. A conceptual framework is developed for modeling the dynamic price discounting strategy in retail using fuzzy logic. Findings – The model captures the lag effect of sales promotion and price discounting strategy; other strategies have been formulated based upon the sales forecast that was done for taking the lot sizing decisions regarding procurement of products in the selected category. This has helped minimize the inventory cost thereby keeping the profitability of the retail organization intact. Research limitations/implications – There is no appropriate empirical data to verify the models. In light of the research approach (modeling based upon historical time series data of a particular product category) that was undertaken, there is a possibility that the research results may be valid for the product category that was selected. Therefore, the researchers are advised to test the proposed propositions further for other product categories. Originality/value – The study provides valuable insight on how to use the real-time sales data for designing a dynamic automated model for product sales promotion and price discounting strategy using fuzzy logic for a retail organization. © 2016, © Emerald Group Publishing Limited.

Continuity and change are key paradigms of strategic thinking. Most of the literature has focused on strategic change and gradual transformation. Dealing with flexibility, continuity and change has been an area of growing interest to researchers and business organisations to cope with the uncertainty. Outbound automotive supply chain, involving large dealer network, third party logistics and multimode transportation, has become very complex. Vehicle recall, hence, reverse supply chain, has now become common and needs to be included in any strategy for outbound supply chain. This research work focuses on study of outbound supply chain of the largest automotive company in India and understanding how they are coping up with the forces of continuity and change. Based on this research, the aim is to develop a flexible strategic framework for effectively managing forces of continuity and change in outbound supply chains, which can be applied to other similar organisations.

Short-term approaches or patch working are the predominant modes of solving process-related problems in organizations. As a result, problems recur at regular intervals and inhibit their smooth functioning. Organizational leaders have adopted various quality initiatives to produce sustainable change, but the existing literature suggests that many of them have met with limited success. The 'A3 Process', adapted from Toyota Motor Corporation, has been proposed as a pragmatic problem-solving technique for creating sustainable organizational change. Observing, drawing iconic sketches, discussing with other stakeholders, and experimenting has helped each stakeholder gain a deeper, contextualized understanding of the problem. These activities influenced knowledge validation and/or knowledge creation, both instrumental in transforming the stakeholder's passive mindset to a collaborative and active mindset. This article presents one of the many applications of the A3 Process that produced enduring change in a health care environment. © 2012 SAGE Publications. Source
