@Research Paper <#LINE#>Six-Sigma Application in the Hotel Industry: Is It Effective for Performance Improvement?<#LINE#>Kamar@MahmoudS.Abou<#LINE#>1-14<#LINE#>1.ISCA-RJMS-2014-096.pdf<#LINE#>Department of Hotel Studies, Faculty of Tourism and Hotels, Sadat City University, EGYPT<#LINE#>7/11/2014<#LINE#>15/11/2014<#LINE#> Six-Sigma (6) is a quality improvement strategy that provides a clear roadmap for organizations to deliver nearly perfect products and services. After initial success in manufacturing organizations, Six-Sigma has gradually gained widespread application in service organizations, including hotels and lodging. Although the hotel industry has an increased interest in Six-Sigma implementation and many hotels have yielded tangible benefits from this approach, the literature is limited. Moreover, the relationship between Six-Sigma implementation and its performance improvement outcomes is a rarely examined subject in the hospitality context. Therefore, this study attempts to assess the effectiveness of Six-Sigma and examine its impacts on various performance measures of upscale hotels in Egypt, seeking for what values and benefits it brings to improve the overall performance. To achieve this objective, the researcher surveyed 123upscale hotels in Egypt. Data were analyzed using Statistical Package for Social Science (SPSS 18). The results indicated that only 31 percent of the respondent hotels are actively involved in a documented Six-Sigma project. A notable proportion of these hotels have less than three years experience with the Six-Sigma approach. This clearly illustrates that Six-Sigma is a relatively new approach within the Egyptian hotel industry. The findings indicated that Six-Sigma implementation is positively and significantly associated with the operational and competitive performance of the surveyed hotels. Hotels implementing Six-Sigma have achieved more benefits as compared to other hotels implementing other quality management programs (i.e. TQM and ISO 9001). Therefore, it seems advisable for Egyptian hotels to be involved in formal Six-Sigma projects in order to improve their overall performance. <#LINE#> @ @ Linderman K., Schroeder R.G., Zaheer S. and Choo A.S., Six-Sigma: A Goal Theoretic Perspective, Journal of Operations Management, (21), 193- 203(2003) @No $ @ @ Snee R.D. and Hoerl R.W., Leading Six-Sigma, Prentice-Hall, ISBN: 0130084573, Englewood Cliffs, NJ.

It is very important factor to any orgnisation. It helps to achieve the objectives of the business and helps to carry the smooth working of an orgnisation. The very prominent process in an economy is the cash flow and currency flow within the economy. It has unique assets and most important to quality system to be able to maintain the flow of cash and currency between outlets, Banks and customers. With the changing enviournment of today’s era bank has faced a huge challenge that is change, banks needs to be very careful and updated with the changing standards. To overcome the shrinking deposits, to increase the number of accounts etc. bank has to be updated and come up with the new technique Cash Management Services. Hence the objective of this paper is to study the Role of cash management system in Banking Sector. <#LINE#> @ @ Robbins S., Bergman R., Stagg I. and Coulter M., Management, Prentice-Hall Astrellia Ptv,.

Also, it has been proven that the general TLPP is an NP-hard problem. The literature shows a few attempts for solving using TLPP. In this paper, we attempt to develop two effective approaches, one based on Taylor theorem and the other based on the hybrid algorithm by combining the penalty function and the line search algorithm for solving the linear TLPP. In these approaches, by using Karush-Kuhn-Tucker conditions, TLP Pischanged to non-smooth single problem, and then it is smoothed by proposed functions. Finally, the smoothed problem is solved using both of the proposed approaches. The presented approaches achieve an efficient and feasible solution in an appropriate time which has been evaluated by comparing to references and test problems. <#LINE#> @ @ Bard J.F Some properties of the bi-level linear programming, Journal of OptimizationTheory and Applications 68, 371–378 (1991) @No $ @ @ Vicente L. et.al, Descent approaches for quadratic bi-level programming, Journal of Optimization Theory and Applications, 81, 379–399 (1994) @No $ @ @ Yibing Lv et.al, A penalty function method Based on Kuhn–Tucker condition for solving linear bilevel programming, Applied Mathematics and Computation, 1(88), 808–813 (2007) @No $ @ @ Allende G.B. et.al, Solving bi-level programs with the KKT-approach, Springer and Mathematical Programming Society, 1(31), 37– 48 (2012) @No $ @ @ Mathieu R. et.al, Genetic algorithm based approach to bi-level Linear Programming, Operations Research, 28, 1–21 (1994) @No $ @ @ Wang G. and Jiang B., Global convergent algorithm for the bi-level linear fractional-linear programming based on modified convex simplex method, Journal of Systems Engineering and Electronics. 239–243 (2010) @No $ @ @ Wend W.T and Wen U.P., A primal-dual interior point algorithm for solving bi-level programming problems, Asia-Pacific J. of Operational Research, 17 (2000) @No $ @ @ Hosseini E andNakhai Kamalabadi I., Line Search and Genetic Approaches for Solving Linear Tri-level Programming Problem, International Journal of Management, Accounting and Economics,1(4), (2014) @No $ @ @ Sanjay Bhaskaran and R.
