Daha hızlı veri iletişimine izin veren ve büyük veri
üzerinde çalışmaya fırsat sağlayan bilgi sistemlerinin sürekli gelişimi ile
birlikte, işletmelerin karar alma süreçlerinde analitik yaklaşımları
uygulamaları daha mümkün hale gelmiştir. Bu gelişmeleri takiben, girdiler,
çıktılar ve süreçlerin yönetiminde başarılı olabilmek için tedarikçi, işletme
ve müşteri faktörlerini ele alan sistematik bir yaklaşım gereklidir. İşletmeler
rekabetçi pazarda hayatta kalabilmek için, sadece kendi sistemlerini değil,
tedarik zincirinin bütününü dikkate olarak kendilerini geliştirmek zorundadır.
Tedarik zincirlerinin genel performansını etkileyen faktörler ile bu
zincirlerdeki aktörlerin başarı kriterlerinin değerlendirilmesi,
sürdürülebilirliğin bir parçası haline gelmiştir. Bu çalışma kapsamında
firmaların var olan tedarikçilerinin etkinliklerinin değerlendirilmesi için
Veri Zarflama Analizi (VZA) temelli bir karar modeli oluşturulmuştur.
Oluşturulan model, tekstil endüstrisinde yer alan bir işletmenin
tedarikçilerinin performanslarının değerlendirilmesine yönelik olarak
uygulanmıştır. VZA yönteminden elde edilen bulgulara göre tedarikçilerin
geliştirilmesine yönelik değerlendirmelerde bulunulmuştur.

ANALYTIC HIERARCHY PROCESS AND DATA ENVELOPMENT ANALYSIS METHODS BASED MODEL PROPOSAL FOR IMPROVING SUPPLIER EFFICIENCIES AND A CASE STUDY

With the
continuous development of the information systems allowing faster data
communication and providing an opportunity to work on big data, it is now more possible
for enterprises to implement analytical approaches on decision-making
processes. Following these advancements, a systematic approach that address
supplier, enterprise, and customer factors to successfully deal with inputs,
outputs and process management is required. To survive in competing markets,
enterprises must improve themselves by considering not only their own system
but also the entire supply chain. Factors affecting the overall performance of
the supply chains and the evaluation of the success criteria of all actors have
become a part of sustainability. In this study, a decision model based on Data
Envelopment Analysis (DEA) has been developed for the evaluation of suppliers’ efficiencies
in the enterprises. The proposed model has been applied to evaluate the
performances of suppliers of an enterprise in the textile industry. According
to the findings obtained from the DEA method, evaluations for the improvement
of suppliers are presented.
