Abstract
Choosing a suitable supplier of materials and equipment in the healthcare sector is essential because it directly affects the patient's health and the organization's effectiveness and quality of services. Moreover, studies on supplier ranking are few in the field of health, particularly in the dental sector. For this purpose, an integrated fuzzy (AHP-TOPSIS) model has been developed for supplier ranking in the dental sector. The F-AHP is used to evaluate the importance of criteria, and then the F-TOPSIS method is applied to the supplier ranking process. A real case study is conducted on dental composite filling suppliers. Six evaluation criteria are identified, and five potential suppliers are selected through a direct interview with a group of experts. Then a questionnaire is applied to 12 experts (dentists) to rate the importance of evaluation criteria and to evaluate suppliers based on evaluation criteria. Evaluating the importance of criteria using F-AHP indicated that quality is the most important criterion. It has a weight of 0.22, followed by esthetic and durability with a weight of 0.21 for both. Moreover, the result of ranking using F-TOPSIS indicated that supplier A5 is the top supplier with a value of (0.532).
Highlights
The study identified the evaluation criteria that govern an accurate assessment of dental composite fillings suppliers. The F-AHP and F-TOPSIS methods are used to rank the suppliers. The result of the criteria evaluation indicated that quality is the most important criterion, followed by esthetic and durability criteria
