Starting from 'Mini-Three-Links' in 2001,'Three-Direct-Links' in 2008, and the Economic Cooperation Framework Agreement (ECFA) signed in 2012, Taiwan has experienced a deeper economic engagement with China. Although the 'Mini-Three-Links' has been often unilaterally restricted, the total trading amounts across the Taiwan Strait in 2018 still rank first among all countries and regions trading with Taiwan. In order to assist freight forwarders quantifying and optimizing the route selection decision, the study starts from a typical transportation network modeling approach and then considers the objectives of jointly minimizing the total system costs and time based on different custom inspection time settings. A nonlinear time-dependent function with a penalty function is formulated to reflect the characteristics of time-sensitive freight and to avoid significantly exceeding the maximum allowable delivery time, while also considering the custom clearance and quality inspection processes within the studied network. Findings show that custom clearance and quality inspection time of cargos do affect the system performance, especially for terminals near the Quanzhou area. In addition, political issues and/or COVID-19 impacts on the 'Mini-Three-Links' closures are analyzed, to provide alternative path plans for targeted freight forwarders in Taiwan. |
