After an earthquake, the debris generated by it can hinder relief efforts, resulting devastating economic, environmental, and health problems. This paper reviews the condition of post‐earthquake situation in Bhutan and develops a mathematical model for improving the condition. Earthquake debris management system plays a vital role in managing the debris after the disaster, thus accelerating the early recovery of the affected regions. The modelling aims to optimize the disaster‐debris transportation cost along with selecting suitable debris dumping site. The outcomes improve the lifestyle of the people of the affected area simultaneously reducing the debris transportation cost and utilizing the reusable items. To analyse the phenomenon, the mathematical models are derived which would be validated through some real data collected from available literature on disaster management. Other than existing literature, the process of segregation of the reusable items is performed at the time of removal of debris from the affected regions which is preferable for comparatively small disaster and hilly areas like Bhutan. The study shows that the after disaster debris management cost can be reduced by determining a suitable TDMS and the loss of property can be saved up to a certain amount by reusing the undamaged or slightly damaged debris.
