Özet:

Although Turkey is the world’s fifth largest tea producer, its share in the world’s tea export volume is undeniably low. In addition, the cost of the dry tea unit production in Turkey is much higher than the cost of the unit of other producing countries. The position of the most important actor in the Turkish tea industry depends on the fact that the ÇAYKUR has an advantage in competition with private sector companies and other country producers to effectively use its resources. Models of Blind Data Coverage Analysis (BVZA) are extremely useful tools used to measure the efficiency levels of decision-making units in a blind environment. In this study, the activity measurement was carried out in the 20 year old tea processing factory associated with ÇAYKUR according to the 2013 data. The application used by the BVZA model developed by Lertworasirikul and others (2003a) calculated the performance scores at five different α-cutting levels for factories. In the next stage, a single performance score was calculated for each factory, using the foolish ranking approach granted to literature by Chen and Klein (1997) in order to rank the factory according to its performance. The study is believed to provide useful information to the decision makers in the sector. Moreover, this study is one of the first studies carried out with the BVZA model in the world tea industry.
