Tensegrity grids composed of tensegrity units that form double layer cable nets of single or double curvature can find applications in architecture as surface structures. In this paper a parametric process for the geometric configuration and representation of double layer tensegrity structures of helical shape is discussed. Departing from the geometric construction process, an algorithm that fa...

Since China joined the WTO in 2001, the pressure for bank reforms has mounted as China ought to fully open up its financial market to foreign competition by 2006. Efficiency is key for domestic banks to survive in a liberalised environment, but it appears that the last hope for raising bank efficiency is through ownership reform. Whether ownership reform and foreign competition can solve China’...

In this paper a multi - objective linear fractional programming problem with the fuzzy variables and vector of fuzzy resources is studied and an algorithm based on a parametric approach is proposed. The proposed solving procedure is based on the parametric approach to find the solution, which provides the decision maker with more complete information in line with reality. The simplicity of the ...
