An integrated fuzzy AHP and TOPSIS model for evaluating the performance of raw material suppliers: A case study in lasem batik writing centre

Batik is labelled as an identity of Indonesia as in 2009 UNESCO recognized batik as a cultural heritage of no object. The export value of batik in 2015 reached USD 156 million. This study aims to evaluate the performance of raw material suppliers using five criteria, i.e., price, quality, delivery, flexibility, and service. The combination of the fuzzy analytic hierarchy process (FAHP) and technique for others reference by similarity to ideal solution (TOPSIS) are used here to achieve the research objective. FAHP was used to determine the weight of each criterion; while TOPSIS was employed to identify the ranking of all alternatives to be considered. A case study was conducted at Lasem batik writing centre. FAHP results show that quality becomes the most important criterion with the weight of 0.266. The best suppliers of raw materials are LI, PA, and SL for fabrics, dyes, and wax respectively. Findings of this study may offer batik craftsmen in determining what are the best suppliers to be considered based on their performance
