Abstract
Prestressed concrete structures are used all around the world widely; especially for elements which are under the effects of bending like prestressed concrete slabs. In these sorts of elements the aim of designing is to control the tensional stresses and the cracks delivering higher strength. This can improve the capabilities of the structure, architecturally and economically. Seismic design of structures is based on horizontal component of ground motions. In recent years, it has been observed that the vertical component of ground motion could be stronger than horizontal one especially for those which have happened in near field sources. In these kinds of earthquakes the importance of...

, M.Sc. Thesis Sharif University of Technology ; Akbari Jokar, Mohammad Resa (Supervisor) ; Memari, Ashkan (Co-Supervisor)
Abstract
Today, with the expansion of business relations at international levels, there are many organizations that operate in global supply chains. Activities at such levels face new types of challenges in various fields of "supply chain management" pillars, of which "supplier selection" is one of them. The possibility of unexpected events, the need to comply with environmental protection laws, as well as the need to take into account social considerations, are among the things that have increased by being in larger supply chains, making it challenging to provide the basic resources needed in such chains and forcing their managers to considering considerations other than what they have always...
