Abstract
Today, business organizations are facing increasing pressure from a variety of sources to operate using sustainable processes. Thus, most companies need to focus on their supply chains to enhance sustainability to meet customer demands and comply with environmental legislation. To achieve these goals, companies must focus on criteria that include CO2 (carbon footprint) and toxic emissions, energy use and efficiency, wastage generations, and worker health and safety. As in other industries, the food processing industry requires large inputs of resources, which results in several negative environmental effects; thus, decision-makers have to evaluate qualitative and quantitative factors. This work identifies the best supplier for edible oil production in the small and medium enterprise (SME) food processing industry in Vietnam. This study also processes a hybrid multicriteria decision-making (MCDM) model using a fuzzy analytical hierarchy process (FAHP) and green data envelopment analysis (GDEA) model to identify the weight of all criteria of a supplier’s selection process based on opinions from company procurement experts. Subsequently, GDEA is applied to rank all potential supplier lists. The primary objective of this work is to present a novel approach which integrates FAHP and DEA for supplier selection and also consider the green issue in edible oil production in uncertain environments. The aim of this research is also to provide a useful guideline for supplier selection based on qualitative and quantitative factors to improve the efficiency of supplier selection in the food industry and other industries. The results reveal that Decision-Making Unit 1 (DMU 1), DMU 3, DMU 7, and DMU 9 are identified as extremely efficient for five DEA models, which are the optimal suppliers for edible oil production. The contributions of this research include a proposed MCDM model using a hybrid FAHP and GDEA model for supplier selection in the SME food processing industry under a fuzzy environment conditions in Vietnam. This research also is part of an evolution of a new hybrid model that is flexible and practical for decision-makers. In addition, the research also provides a useful guideline in supplier selection in the food processing industry and a guideline for supplier selection in other industries.
Highlights
IntroductionThe global global edible edible oil oil market market is is expected expected to to witness witness significant significant growth growth due due to to the the increasing increasing prevalence of unrefined, unprocessed, healthy, and organic oil
Supplier selection plays an important role in supply chain management, contributing to the success of production-business organizations
One of the fields that the multicriteria decision-making (MCDM) model has been applied to is for supplier selection in edible oil production, yet very few studies consider this problem with green issues and under fuzzy environmental conditions
Summary
The global global edible edible oil oil market market is is expected expected to to witness witness significant significant growth growth due due to to the the increasing increasing prevalence of unrefined, unprocessed, healthy, and organic oil. In the years to come, vegetable prevalence of unrefined, unprocessed, healthy, and organic oil. In the years to come, vegetable oil oil that that is is low low in in cholesterol, cholesterol, fat, fat, and and calories calories is is likely likely to to receive receive great great attention attention due due to to increased increased health health awareness. In. In addition, addition, major major improvements improvements in in retail retail networks, crop yields, and developing economies are among the key factors supporting the growth of the global and developing economies are among the key factors supporting the growth of the global edible edible oil oil market. The the growing growing popularity popularity of of canola canola oil, oil, trans trans fat-free fat-free soybean soybean oil, oil, and and emerging emerging olive olive oil oil will will fuel fuel the the global global edible edible oil oil market market [1].
