Abstract

The main aim of the research was to scheduling commercial trucks at a Thailand - Malaysia border crossing case study of Sadao Border, Songkla. To from the study reference research about border crossing find that use more time for pass process of customs clearance 68% use time less than 6 hour and 27% use time more than 6 hour but less than 12 hour in weekday. This research develops the scheduling assignment for the commercial trucks by using Earliest Due Date rule (EDD) and for flow shop (Non-permutation). The simulation approach using ProModel® software is employed to model the actual system. By will consider in time and cost reduction result for border crossing. By implementing the scheduling concept, the results show that the truck waiting time decreases by 88.26% (31 minutes per truck), reduces the average time in system by 53.55% (178.36 minutes per truck), and diminishes the transportation cost 155.01 Baht per trip. The proposed method provides an advantageous solution for the decision-makers in order to improve the effectiveness of the border crossing activities.
