Abstract
The main objective of this research is to enhance the cold chain logistics for vaccine transportation to maintain product quality. This is achieved through the utilization of digital technology and transportation innovation to control temperature and ensure timely delivery. Various research tools and technologies are employed, such as Geographic Information System (GIS) Analysis and the Vehicle Routing Problem (VRP). The study involves analyzing and examining data to determine the most suitable spatial and transportation routes for vaccines, reducing both distance and delivery time. The primary aim is to improve the efficiency of vaccine management and transportation while preserving the quality of vaccines during the cold chain management process. The study focused on 76 locations, including hospitals and public health service centers in Bangkok. The research findings indicate that spatial analysis and the use of the Vehicle Routing Problem can efficiently identify suitable distribution centers and optimal routes, ultimately leading to more systematic and efficient vaccine management and transportation. Spatial analysis helps pinpoint locations that align with vaccine distribution needs, while the Vehicle Routing Problem calculates routes that reduce delivery time and distance.
