Fuzzy TOPSIS Method in Supplier Selection and Application in the Garment Industry
Yayla, A. Yesim; Yildiz, Aytac; Ozbek, Ahmet (INST CHEMICAL FIBRES, 2012)In today's world where intensive competition exists between enterprises, it is of great importance to work in cooperation with the right suppliers. Selection of the right suppliers is a significant factor in the success ... -
Generalised Choquet Integral Algorithm for Subcontractor Selection in the Textile Industry - A Case Study for Turkey
Yayla, A. Yesim; Yildiz, Aytac; Yildiz, Kubra (INST CHEMICAL FIBRES, 2013)Turkish textile firms work under a heavily competitive atmosphere in terms of prices due to globalisation. Firms have to take into consideration several criteria in order to survive the global market conditions and to ... -
The importance of Bohler's angle in calcaneus geometry: A finite element model study
Gultekin, Alper; Acar, Erdinc; Ugur, Levent; Yildiz, Aytac; Serarslan, Ulas (Turkish Joint Diseases Foundation, 2021)Objectives: Calcaneal fractures are the most common tarsal fractures following a foot-ankle trauma. The Bohler's angle is an important measurable angle before, during, and after surgery. In this study, we aimed to investigate ... -
Interval type 2-fuzzy TOPSIS and fuzzy TOPSIS method in supplier selection in garment industry
Yildiz, Aytac (INST NATL CERCETARE-DEZVOLTARE TEXTILE PIELARIE-BUCURESTI, 2016)Supplier selection requires the consideration of multiple factors, and it can be viewed as a multi criteria decision making (MCDM) problem. Fuzzy Technique for Order Preference by Similarly to Ideal Solution (TOPSIS) is ... -
Investigation of effect on energy consumption of surface roughness in X-axis and spindle servo motors in slot milling operation
Ozturk, Burak; Ugur, Levent; Yildiz, Aytac (ELSEVIER SCI LTD, 2019)The energy cost is a significant expense in the machining companies, and the reduction of energy consumption has a critical prescription in the industry. To increase energy efficiency, machine producers have contributed ... -
OPTIMIZATION OF CUTTING PARAMETERS USING THE RESPONSE SURFACE METHOD
Guvercin, Salih; Yildiz, Aytac (YILDIZ TECHNICAL UNIV, 2018)Some cutting parameters have to be considered in order to obtain high-quality surfaces in machining. Because poorly selected cutting parameters cause both the cutting tools to wear out quickly and the surface to become ... -
Optimization of the Cutting Parameters Affecting the Turning of AISI 52100 Bearing Steel Using the Box-Behnken Experimental Design Method
Yildiz, Aytac; Ugur, Levent; Parlak, Ismail Enes (Mdpi, 2023)In this study, we aimed to optimize the cutting parameters that affect the minimum temperature and power consumption in the turning of AISI 52100 bearing steel. For this, the Box-Behnken experimental design method, which ... -
