Bioprosthetic heart valve consists of valvular leaflets, supporting stent and sutural ring valvular leaflets made with polymer materials of porcine or bovine pericardial can be opened or closed by ejected blood. [4].Its flow pattern is central-like.
For rigid stent material, displacement vectors of every point in brim of a leaflet are zero, so the boundary condition can be expressed as: {δ} = { u , v , w , Qx , Qy , Qz }T = {0, 0, 0 , 0 , 0, 0}T In this paper, we use 35, 50, 100 suture points on the attachment edge to stand for different suture points and the displacement vectors of every point is zero.

World Class Manufacturing methodology as an example of problems solution in Quality Management System Katarzyna Łyp-Wrońska 1 1 AGH Faculty of Science and Technology, Faculty of Non-Ferrous, 30 Mickiewicz Av., 30-059 Krakow, Poland Keywords: lean management, World Class Manufacturing (WCM), quality management system Abstract: The article presents the methodology of World Class Manufacturing (WCM) used in one of the factory the mechanical engineering industry.
In this case, Ishikawa diagram (Fig. 4) was used, and the main categories of causes that were taken into account are: man, method, material, machine.
Main components are: - The cost of performing the action (material + labour) – cost (C) - Benefit: reduction in time lost as a result of moving the reservoirs, eliminating the number of reported complaints) - The ratio of profit to cost (B/C) is 15.
