Standard Deviation in the Business World Literature Review In order to demonstrate the applicable uses of standard deviation and other measures of central tendency to the study of business-based economics, it is informative to study the empirical research conducted by researchers with expert knowledge in the field. To that end, an article titled "A Robust Mean Absolute Deviation Model for Portfolio Optimization," which was jointly authored by Korean researchers Yongma Moon and Tao Yao, has been chosen for further review. Published in the scholarly journal Computers and Operations Research in 2011, this comprehensive combination of literature review and statistical modelling is intended to test the efficacy of applying standard deviation to the process of portfolio optimization. In this paper, the authors develop a robust model for portfolio optimization based on their own...
The purpose of this research is to expand the base of empirical knowledge on a phenomenon known as 'parameter uncertainty' by exerting increased control over the potential impact of estimation errors on optimal portfolio strategy performance. The authors construct a statistical model premised on robust mean absolute deviation (RMAD), which precipitates the development of a linear program and reduces the inherent computational complexity of currently implemented robust portfolio optimization techniques. Throughout the paper, Moon and Yao rigorously test their robust strategies by applying them to real market data, while engaging in an objective discussion on the performance level exhibited by a robust optimization model which is empirically founded on financial elasticity, standard deviation, and market conditions including…
Manufacturing Seven Key Elements for Successful Implementation Norman Binette, Jr. Biddeford, Maine Manufacturing organizations are built on the premise that they possess the ability to provide a wide variety of quality products for their customers. This reputation is dependent upon the constant review of existing processes and the identification of new and innovative methods of production that will enhance and increase the diversification of product lines. One such process that has proven itself

9% to 734 units (Khun, 2009) Additionally, James Moss, of Curzon Investment Property, has commented (Khun, 2009) that Dominos and Subway have been successful in the UK market as a result of their franchise models that are almost recession proof. In addition many investors (who want to own a franchise) have found these two chains to be exceptional investments. Additionally, many "Britons are also shunning posh business lunches and choosing instead
Adoption and diffusion of sustainable digital business model in the GCC: Opportunities and ChallengesAbstractThe adoption and widespread diffusion of the sustainable digital business model (SDBM) is an important step towards promoting sustainable development and reducing the environmental impact of business operations in the Gulf Cooperation Council (GCC) region. The implementation of SDBMs, though, faces multiple challenges that are directly related to the unique socioeconomic and cultural characteristics of the GCC
According to Brech, these trends do not leave much time -- or money -- available for dining at full-service restaurants. In this study, the respondents "reported their families ate at cafeterias, family or chain restaurants, or fine dining restaurants only once or less each week" (Brech 1998: 21). This is not to say, though, that the number of full-service restaurants in countries such as the United States has declined
Finance-dominated proponents also maintain that boom economic periods generate a more varied divergence of valuations that fuel merger activity (Medlen 2007). In this regard, Medlen concludes that, "Taken collectively, these understandings may explain some of the merger activity in booms, but they involve certain asymmetries that undercut their explanatory power. High stock valuations allow stock to be utilized as currency and collateral for takeovers; yet stock booms also make
