Interval TOPSIS method for ranking Casting parts supplier of Tabriz Tractor Manufacturing Company

Interval TOPSIS method for ranking Casting parts supplier of Tabriz Tractor Manufacturing Company

Sometimes in the real world we are faced with the data occupying on interval for which providing the exact value for them is hard and complicated. Therefore, when we want to rank such data we need to use advanced decision making methods. In the conventional decision making, the developed TOPSIS method for interval data as one of the classical methods of multiple criteria decision making is important. In this paper we are going to concentrate both on ranking and selecting appropriate suppliers ...

The best method represent and evaluation of DNA extraction of Medusozoa in the Oman Sea

The Medusozoa are a subphylum of the phylum Cnidaria including about 3800 species in three classes: Hydrozoa, Cubozoa, and Scyphozoa (Daly et al., 2007). Cnidarians emanated early in the history of metazoan evolution as exhibited by fossil evidence (Ausich and Babcock, 1998; Cartwright et al., 2007; Chen et al., 2002; Hagadorn and Waggoner, 2000; Han et al., 2010) and molecular phylogenies (Dunn et al., 2008; Peterson et al., 2004, 2008). Medusozoans enclose a variety of forms, containing ...
