Abstract
Supply chain management (SCM) for exporting Thai pineapples to China is a critical component of Thailand’s agricultural export sector. However, the export process faces significant challenges
due to inadequate communication and coordination among upstream and downstream actors. For example, farmers often lack close contractual relationships with factories, shippers, and dealers, which leads to problems with product quality, post-harvest handling, and damage during processing and transportation. The aim of this study was to analyze the Thai pineapple export supply chain to China with R3A route (Chiang Rai to Kunming) by using Value Stream Mapping (VSM). Data collection involved interviews and on-site observations with all stakeholders in the export process, such as farmers, trimming factory, shippings, customs and dealers from China. The interactions among these groups are critical for identifying and minimizing waste across the supply chain. The result of this study could identified 38 activities across the supply chain. The VSM results showed 5 activities, 10.70% were NVA, 30 activities 82.12% were NNVA, and 8 activities 7.18% were VA. The activities could be reduce time and improve efficiency was NVA and NNVA. For instance, dealers waiting time confirmation from factory 1,440 mins, waiting truck to load in pineapple farm 60 mins. The principles of lean manufacturing are applied through close communication, effective collaboration, and contract farming among farmers, trimming factories, and dealers. Lead times are thereby reduced, and the efficiency of supply chain management for Thai pineapple exports to China is enhanced.
