Rising product variety and complexity, shorter time frames to respond, and the continual need to gain new capabilities through innovativeness force the trend of outsourcing to be replaced by strategic alliances, where enterprises or individuals work together towards a common goal and share their responsibilities as well as their profits. Recent developments in information technology have enabled relatively inexpensive, reliable and fast networking to support such alliances in real time. In this context, the virtual enterprise (VE) represents an appropriate cooperation alternative and competitive advantage for the enterprises. VE is a temporary network of independent companiessuppliers, customers, even rivals -linked by information technology (IT) to share skills, costs and access to one another's markets. In this emerging business model of virtual enterprise, the decision support functionality, which addresses issues such as partner company selection, is an important domain to be studied. In this paper, we propose an analytic hierarchy process model to contribute in the selection of the partner companies in the virtual enterprises.A case example is also covered to validate the feasibility of the adoption of the model in virtual enterprise situations.
Compression stockings, which constitute one of the most important groups of compression garments, are engineered to regulate blood flow in venous systems in order to use in many medical fields such as supporting muscles and preventing edema. In the present study, it was aimed to analyze the effects of production parameters such as tightness, elastane yarn feeding tension and elastane yarn counts on pressure behavior of compression stockings, which are commonly used to adjust pressure values. The results of the statistical analysis indicated that the tested parameters had significant effects on pressure characteristics of compression stockings. Moreover, multiple regression analysis was used to investigate the relationship between the fabric parameters and pressure values. The analysis exhibited the strong impact of thickness and traversal elasticity on pressure characteristics. All parameters have positive impacts except traversal elasticity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
