Evaluation and Performance Analysis using ANP and TOPSIS Algorithm

Suppliers play an important role in supporting the supply chain within the company. Therefore, evaluation of suppliers in the company is a problem that is studied to improve the performance of the company's supply chain. The purpose of this study is to evaluate the performance of green suppliers using the Analytic Network Process (ANP)-Technique for order performance by similarity to ideal solution (TOPSIS). ANP is used to weigh each factor and criteria, and TOPSIS is used to evaluate the performance of green suppliers. This research is a case study on the construction industry in Indonesia. Six factors and fourteen sub-criteria are used to evaluate the performance of green suppliers. Based on the ANP method, the cost factor is the criterion that has the highest weight, which is 0.44318. The sub-criteria that has the highest weight is product price, with a weight of 0.2681. Furthermore, the order of green supplier performance based on TOPSIS shows that supplier B ranks first, followed by suppliers A, D, and C.
