Choosing the right supplier is an important part of maintaining an effective and efficient supply chain. In reality, this decision can be very difficult because it involves many different factors, such as price, quality, delivery time, and supplier reliability. This study presents a Decision Support System (DSS) that uses the Simple Additive Weighting (SAW) method to help select the best supplier based on these criteria. The SAW method is known for its straightforward approach to multi-criteria decision making, making it an ideal choice for this type of task. A prototype of the system was developed and tested using sample supplier data to assess its performance. Based on the results, the system was able to provide accurate and consistent recommendations, helping users identify the most suitable suppliers for their needs. This research offers a practical tool that can support businesses in making better supplier decisions and demonstrates how the SAW method can be effectively applied in everyday business scenarios.
