尽管关键路径理论中强调关键路径上的任务没有浮时，但在实际的项目资源管理

尽管关键路径理论中强调关键路径上的任务没有浮时，但在实际的项目资源管理中，可能会通过资源优化（比如资源平衡）为关键路径上的某些任务创造出浮时，特别是当任务不能因为资源限制而正好开始时。这可能导致关键路径上某些任务的浮时为正值。

Although the critical path theory emphasizes that tasks on the critical path do not have floating hours, in actual project resource management, resource optimization (such as resource balancing) may create floating hours for certain tasks on the critical path, especially when the task cannot start precisely due to resource constraints. This may cause the float time of certain tasks on the critical path to be positive.

Although the critical path theory emphasizes that the tasks on the critical path have no floating time, in the actual project resource management, floating time may be created for some tasks on the critical path through resource optimization (such as resource balance), especially when the tasks cannot start just because of resource constraints. This may cause some tasks on the critical path to have positive float times.
