Supplier Selection Fuzzy Model in Supply Chain Management: Vietnamese Cafe Industry Case

Abstract

Supplier selection is a vital part of the supply chain and is also a current issue that concerns businesses today as supplier quality directly affects the operations of the organization. Choosing the right supplier can help businesses increase productivity, competitiveness in the market, and profits without having to lower the quality of the products. However, choosing a supplier is not a simple matter, it requires businesses to consider many aspects about their suppliers. Therefore, the goal of this study is to propose an integrated model consisting of two models: Fuzzy Analytics Network Process (Fuzzy-ANP) model and Weighted Aggregated Sum Product Assessment (WASPAS) to solve the problem above. The Fuzzy-ANP model was developed to evaluate the weightings of the supplier selection criteria, and the WASPAS Model was used to rank the suppliers. An example of supplier selection in the coffee industry in Vietnam was studied to validate the model, namely 5 main criteria, with 16 sub-criteria, and 7 suppliers. The model test results show that the Fuzzy ANP and WASPAS integration model was suitable. In future, these developing models can apply to other industries or integrate with other models.

Fuzzy Trapezoidal DEMATEL Method for Criteria Weights in Supplier Selection: A Case Study of Ice Cream Producer

“…Making Trial and Evaluation Laboratory (DEMATEL) (Göncü & Çetin, 2022;Sumrit & Jiamanukulkij, 2022), and Step-wise Weight Evaluation Rate Analysis (SWARA) (Tus & Adali, 2022;Xie et al, 2022) have been studied in this regard. Also, many researchers used TOPSIS (Modibbo et al, 2022), ANP (Wang et al, 2022), and AHP (Dang et al, 2022;Lahdhiri et al, 2022). There are applications of the subject in the food industry.…”

Dynamic Model of Sustainable Development for a Coffee Supply Chain

“…In today's companies, the quality of suppliers is of vital importance, as it directly affects the production operations and organization of the company. It also has a direct impact on productivity and competitiveness in the market (Chia-Nan, et al, 2022). To have an efficient agile supply chain, it is necessary to design a participatory model among the actors involved in the coffee industry to reduce the information gaps faced by those involved.…”
