In the context of environmental protection and sustainability, undesirable outputs (such as pollutants and wastes) resulting from activities like production are increasingly gaining attention. Thus, technological improvements that generate fewer undesirable outputs in the scope of production have become an significant topic (Cooper, Seiford, & Tone, 2008) In sustainability researches, the relationship between resource efficiency and performance optimization can be examined in different ways depending on the quantitative methods used. In this regard, the Slack Based Measure (SBM) model and the input-oriented traditional BCC (Banker-Charnes-Cooper) Data Envelopment Analysis model provide important capabilities for assessing the efficient use of resources from a sustainability perspective. (Zhou, Yang, Chen, & Zhu, 2018) This study examines whether there is a difference in efficiency between the SBM (SBM-UO) Data Envelopment Analysis model with undesirable outputs and the standard input-oriented BCC Data Envelopment Analysis (BCC DEA-UO) model with undesirable outputs, within the context of sustainability efficiency, using an industrial case example. Since the slack values are considered, the results of efficiency measurements made with SBM (SBM-UO) show lower or equal values compared to the BCC Data Envelopment Analysis (BCC DEA-UO) with undesirable outputs.

Çevresel koruma ve sürdürülebilirlik doğrultusunda, üretim gibi faaliyetler sonucunda ortaya çıkan istenmeyen çıktılar (örneğin: kirleticiler ve atıklar) giderek daha fazla dikkat çekmektedir. Bundan dolayı üretim alanında daha az istenmeyen çıktı üreten teknolojik gelişmeler önemli bir konu haline gelmiştir. (Cooper, Seiford, & Tone, 2008) Sürdürülebilirlik çalışmalarında, kaynak verimliliği ve performans optimizasyonu arasındaki ilişki, kullanılan kantitatif yöntemlere bağlı olarak farklı şekillerde ele alınabilir. Bu bağlamda, Slack Based Measure (SBM) modeli ile girdi odaklı geleneksel BCC (Banker-Charnes-Cooper) Veri Zarflama Analizi modeli, sürdürülebilirlik açısından kaynakların etkin kullanımını değerlendirmek için önemli araçlar sunar (Zhou, Yang, Chen, & Zhu, 2018) Bu araştırmada, sürdürülebilirlik çalışmaları kapsamında, İstenmeyen çıktı içeren SBM (SBM-UO) Veri Zarflama Analizi modeli ile standart girdi odaklı, istenmeyen çıktı içeren BCC Veri Zarflama Analizi (BCC DEA-UO) modelleri arasında etkinlik açısından bir fark olup olmadığı, endüstriyel alanda bir örnek ile incelenmiştir. Artık değerleri gözetildiği için SBM (SBM-UO) ile yapılan etkinlik ölçümlerindeki sonuçların tamamında değerler, istenmeyen çıktı içeren BCC Veri Zarflama Analizi (BCC DEA-UO)’ne göre daha düşük ve eşit çıkmaktadır.
