Applied Sciences, Vol. 16, Pages 8874: Research on Optimization of Material Transportation Scheduling for Water Conservancy Engineering Considering Emergency Response to Vehicle Malfunctions

5+ day, 19+ hour ago   (453+ words) In-transit vehicle malfunctions during material transportation in water conservancy construction can cause delivery delays, disrupt subsequent tasks, and lead to duplicate material requisitions. To address these issues, this study develops a material transportation scheduling optimization model that explicitly incorporates vehicle-malfunction…...
