In recent years, torrential rain, earthquakes, and overexploitation have resulted in landslides and debris flows at mountain roads. Therefore, the Council of Agriculture, Executive Yuan, proposed the Debris Flow Disaster Prevention and Response Operation Plan and the Strategies for Clearing Obstacles of Road Landslides. Contractors will be contacted upon any events of road landslides, and personnel and equipment will be transported to the site to establish detours and clear debris. In addition, annual open contracts of “natural disaster prevention,” “emergency repair,” and “rehabilitation construction” are contracted out by local township and city governments.
The scope of this study covered contractors’ process of equipment dispatch for emergency repair in road landslide cases. Linear programming was adopted to establish the optimal model that specified the suitable time for equipment dispatch. This model can serve as a reference for future decision-makers who aim to reduce costs to a minimum. Additionally, based on the trend of sensitivity variations, a sensitivity analysis was conducted to find the minimum number of required equipment for damaged areas to fully utilize human and equipment resources. Simulation tests were carried out on mountain road landslide examples to verify the practicality and usability of this model. Moreover, the dispatch results obtained using the optimal model was compared to general manual dispatch processes that were based on experiences. According to the comparison, it was verified that equipment dispatch decisions made by the proposed optimal model were more effective and cost-saving than manual dispatch processes that were based on experiences. Therefore, the results of this study can be flexibly applied to planning and reviewing earthworks and equipment dispatch for people to make accurate decisions. | en_US |
