Maturity of companies, organizational culture and costs are some of the major limiting factors for implementation of cost-effective six sigma methodology in Bosnian companies. Purpose of this paper is to analyze possibilities of applying six sigma concept in a medium-sized company with 200 employees. Considering all characteristics of the company, in this case, implementation model was proposed and tested. The project included process monitoring using statistical process control charts for two different periods, before and after improvement. Dominant defect and its causes were identified and it was found out that the process was out of control. Implementation of improvement measures, dominant defect was eliminated but the process has remained out of control. As a conclusion, the test indicated that the model is effective but it takes more iteration to achieve the desired state.

The fin ite element method were used for the plastic metal flo w predict ion of ring shaped parts. Various parameters that affect the forging operation are the material characteristics like material strength, ductility, deformat ion rate, temperature sensitivity and frict ional characteristics of the workp iece, prefo rm design, die design and die material. Nu merical simulat ion has been done for axisy mmetric automobile parts. The procedure of nu merical modeling contains all simulat ions phases like the movement of p reform fro m inductor to the tool, placement and setting of preform piece inside the tool before the blow in order to get as good result as possible. These techniques are used to reduce the amount of input material for forgings, extend the lifetime of fo rging dies, and prevent defects in forged components.

This paper presents an application of the finite volume method to ideal plastic metal flow in extrusion technology. Governing equations for the mass and momentum balance are used in an integral form. Solution domains in the cases considered are discretized with a Cartesian numerical mesh with computational points placed at the center of each control volume. After discretization of the governing equations, the resulting system of nonlinear algebraic equations is solved by an iterative procedure, using a segregated algorithm approach. Resulting stress fields are obtained from the Levy-Mises equations. The experimental results and numerical calculations are in good agreement.

Many nations are currently adopting a variety of directed strategies to launch and support the development of research parks. Science and technology research parks are seen increasingly as a means to create dynamic clusters that accelerate economic growth and international competitiveness. Technology parks represent the place of SME's development and the place of the most direct technological transfer. Research parks encourage greater collaboration among universities, research laboratories, and SMEs, providing a means to help convert new ideas into the innovative technologies for the market. They are recognized to be a tool to create successful new companies, sustain them and attract new ones, especially in the science, technology, and innovation sector. Universities, in turn, benefit by exposure to the business world. What all these parks have in common is that they are, at heart, knowledge partnerships that foster innovation. University research and science parks provide the launch pad that startup companies need when they are "spun out" from a university or company. The current state of development of technology parks in Bosnia and Herzegovina and possibilities of establishment of a new technology park in Sarajevo (Ilidža) region are analyzed in this paper.
