Parachute Fabric Supplier Selection for a Fashion Brand Using Weighted Sum Model: A Case Study of Chute Up

Abstract

Abstract - Indonesia's fashion industry is rapidly growing, with an estimated value of USD 8.75 billion in 2025. With this rapid growth comes the pressure for fashion companies to adopt efficient strategies, including optimizing their supplier selection process. For Chute Up, a fashion brand producing a 3-in-1 convertible parachute jacket, selecting the right parachute fabric supplier is crucial for quality, cost efficiency, and timely production. This research applies the Weighted Sum Model (WSM) to assist structured decision-making in supplier selection. The criteria used includes quality, cost, delivery, reliability, sustainability, and capacity that were obtained from a literature review and validated through interviews with Chute Up’s C-Level executives. Each criterion was then weighted based on the expert judgment, with quality (0.316) and cost (0.300) being the most prioritized. Three shortlisted suppliers (BLT, AMZ, and BRL) were evaluated using WSM. BRL scored the highest (85.91), followed by AMZ (69.41) and BLT (66.77), making BRL the recommended supplier.
