Modeling and Analysis of Cascading Invulnerability of Logistics Support Networks Based on Task-time Constraints
Jun Ji Wu · Systems Engineering · 2009
Firstly,logistics support network models are established and task-time constraints are defined.Then a cascading invulnerability model based on task-time constraints for logistics support networks is proposed.The effects of task-time constraints on cascading invulnerability are analyzed numerically by an empirical case of logistics support network.It is shown that the duration of task time has great effects on the cascading invulnerability: if the duration of task time is short,the cascading failure is caused by a single-task;if the task duration time is long,the cascading failure is caused by a multi-task.
