Robustness analysis of the algorithm under dynamic event perturbation.
| Disturbance scenario | Dynamic event intensity | Average total transportation cost (yuan) | Cost increase rate (%) | Weighted average delay time (min) | Task completion rate (%) | Std. Dev. of re-planning computation time (ms) |
|---|---|---|---|---|---|---|
| Baseline scenario | 10% road congestion, 5% new orders/hour | 31572.4813 | 0.0000 | 4.1377 | 100.0000 | 1.8834 |
| Low disturbance | 20% road congestion, 5% new orders/hour | 33829.1742 | 7.1476 | 6.8912 | 100.0000 | 2.0169 |
| Medium disturbance | 30% road congestion, 10% new orders/hour | 37451.9288 | 18.6221 | 11.2438 | 99.1667 | 2.4721 |
| High disturbance | 40% road congestion, 15% new orders/hour | 42108.6639 | 33.3713 | 17.5824 | 97.8333 | 3.1593 |
| Extreme disturbance | 50% road congestion, 20% new orders/hour | 48933.0571 | 54.9859 | 4.0278 | 95.5000 | 4.0278 |
