A Conceptual Model for Rubber Supply Chain in the Northeast of Thailand by System Dynamics
The Northeastern of Thailand is a new potential area for rubber growing like other regions such as the South, the East, and the North. Due to its huge suitable areas for rubber growing, there is rapid expansion of new rubber plantations through the region. As a result, the volume of rubber latex has been continuously increasing, and this is the starting point of the rubber industry development in the Northeast Thailand. However, the effective development should be considered as a whole system, from upstream to downstream. The article, therefore, presents a conceptual model for rubber supply chain in the Northeast Thailand by system dynamics. This shows the relationship between components and variables that affect the complex rubber supply chain. Consequently, it helps see the impact according to different factors or variables associating the system. This contributes more efficiency to quantitative analysis in next step that supports any policy decisions or plans by using the total export value of rubber as a main indicator.
