The methodology quantifies vendor performance across five key criteria: quality, cost, delivery, flexibility, and responsiveness. The results indicate that product quality (39.7%) and cost efficiency (41.4%) are the most influential factors in vendor selection. Sensitivity analysis reveals that a 10% increase in quality consistency improves overall vendor ranking stability by 15%, while cost variations above 8% significantly affect final rankings. The study recommends implementing performance-based contracts, quality assurance protocols, and digital supply chain solutions to enhance vendor assessments. Collaborative partnerships with top-performing vendors can yield mutual benefits and foster sustainable practices, aligning with the company&#39;s resilience and operational excellence objectives.</span></span></span></i></div> Vendor Evaluation,Fuzzy Analytical Network Process,Supplier Performance,Vendor Selection Criteria,laser cutting service 141 155 http://ijiepr.iust.ac.ir/browse.php?a_code=A-10-3139-1&slc_lang=en&sid=1 Hendro Prassetiyo prasshendro@itenas.ac.id 1800319475328460013507 1800319475328460013507 Yes Institut Teknologi Nasional, Bandung Said Muhammad Baisa Saidbaisa175@gmail.com 1800319475328460013508 1800319475328460013508 No Institut Teknologi Nasional, Bandung Arif Imran imran@itenas.ac.id 1800319475328460013509 1800319475328460013509 No Institut Teknologi Nasional, Bandung Sri Suci Yuniar suciyuniar7@gmail.com 1800319475328460013510 1800319475328460013510 No Institut Teknologi Nasional, Bandung Rangga Try Anugrah tryrangga1060@gmail.com 1800319475328460013511 1800319475328460013511 No Institut Teknologi Nasional, Bandung
