The choice of theme is identified by the need to improve business processes in organizations, as well as the continuous improvement of overall quality, which is under-represented in the Montenegrin organizations. The state of Montenegro has recognized t he growing importance of small and medium-sized organizations in the development of the national economy. Small and medium-sized organizations are the drivers of future economic growth and development of every country whose competitiveness has to pay special attention. One of the main sources of the competitiveness of small and medium-sized organizations is their pursuit to the business excellence, because it has become the most powerful means of achieving competitive advantage of organizations. The paper investigates certified organizations in Montenegro and their contemporary business and commitment towards business excellence. These organizations in Montenegro adapt its business to international standards and procedures that represent the future of economic growth and development of modern business. Research results of Montenegrin organizations were compared with small and medium-sized organizations from Serbia, which won the awards for business excellence "Quality Oscar" in the category of small and medium-sized organizations, for the last three years (2009, 2010, and 2011). The idea comes from the neccessity of Montenegrin economy to give small contribution in order that small and medium organizations adjust their businesses to the new business.

Measurement error is the difference between the true value and the measured value of a quantity that exists in practice and may considerably affect the performance of control charts in some cases. Measurement error variability has uncertainty which can be from several sources. In this paper, we have studied the effect of these sources of variability on the power characteristics of control chart and obtained the values of average run length (ARL) for zero-truncated Poisson distribution (ZTPD). Expression of the power of control chart for variable sample size under standardized normal variate for ZTPD is also derived.

Turbulent surrounding makes it ecessary for an organisation to improve constantly and in a comprehensive way as well as adjust it to occurring changes. In knowledge society it seems rational to create the process of management by means of the use of pro-qu alitative concepts, methods and tools enabling its effectiveness. It seems that self-assessment should be included in this group because its introduction favours growth of the level of organisational maturity solutions leading to the excellence of organisation functioning. The aim of the publication is the presentation of self-assessment significance as information and knowledge source conditioning later growth of the management process efficiency.

The selection principles have increased enormously in number since the first acceptance sampling plans were developed almost 80 years ago. The majority of these principles are characterized by the fact that they look upon producer and consumer as two opposing parties. However, on many occasions, e.g., in final inspection, producer and consumer represent the same party and, therefore, the used sampling plan should not make an attempt to discriminate between their interests. In this case the interest is to avoid wrong decisions, i.e., reject product of sufficient quality and accept product of insufficient quality. Thus, the natural objective in these cases is to use overall risk for a wrong decision as optimization criteria. Optimum result can be arrived further by the Weighted Poisson distribution. In this paper, a table and procedure are given for finding the Multiple Deferred State-1 (MDS-1) (c1, c2) sampling plan involving minimum sum of producer's and consumer's risks for specified Acceptable Quality Level and Limiting Quality Level using Weighted Poisson distribution. This is the case with so called "Multiple Deferred State-1 (MDS-1) (c1, c2) sampling plan for given Acceptable Quality Level and Limiting Quality Level involving minimum risk s using Weighted Poisson distribution".

Optimization of machining processes is one of the most important elements in the planning of metal parts production. In this paper, we have applied ABC methods to determine the cost of all processes that are used in production of homocinetical sleeve joint. After that we have used multy-criterion optimization technique based on genetic algorithms, in order to optimize the basic parameters of all the processes: the speed and feed. The objective function is given in a form of specific cost for each processes, for which minimization it is need to consider the appropriate mechanical and manufacturing constraints. The proposed model uses a genetic algorithm, so that after a certain number of iterations optimal result is reached that will satisfy the objective function and all anticipated limitations. Obtained results shows that GA solves the optimization problem in an efficient and effective manner, so that the results can be integrated into an intelligent manufacturing system for solving complex optimization problems in machine production processes.

Students' rating of teaching is one of the most widely accepted methods of measuring the quality in Higher Education worldwide. The overall experience gained by the students during their academic journey in their respective college is a key factor to determine the Institutional Quality. This study was conducted among the Physical Therapy students with an objective to capture the overall experience related to various aspects of their Academic environment including teaching and learning process adopted in their college. To facilitate that, a unique questionnaire called, "Academic Environment Evaluation Questionnaire (AEEQ)was developed covering all the important teaching elements of the Higher Education Institutions. The students' opinion was captured and analyzed through six sigma analytical tool using Poisson distribution model. From the non-conformance level captured through the responses from the students about the various categories of teaching and learning elements, the corresponding Sigma rating for each teaching element was measured. Accordingly, a six point Quality rating system was developed customizing to each sigma values. This study brings a new, innovative student driven Quality rating system for the Higher Education Institutions in India.
