The earliest occurrence time for event '1' is 8 weeks and the ...
The total float is the amount of time that an activity can be delayed without delaying the project's completion time. To calculate the total float, we need to consider the earliest and latest occurrence times for both events and the activity time.
Given:
- Event 1: earliest occurrence time = 8 weeks, latest occurrence time = 26 weeks
- Event 2: earliest occurrence time = 32 weeks, latest occurrence time = 37 weeks
- Activity time = 11 weeks
Calculating the earliest start time for the activity:
The earliest start time for the activity is the maximum of the earliest occurrence times for both events. Therefore, the earliest start time = max(8 weeks, 32 weeks) = 32 weeks.
Calculating the latest start time for the activity:
The latest start time for the activity is the minimum of the latest occurrence times for both events minus the activity time. Therefore, the latest start time = min(26 weeks, 37 weeks) - 11 weeks = 26 weeks - 11 weeks = 15 weeks.
Calculating the total float:
The total float is the difference between the latest start time and the earliest start time for the activity. Therefore, the total float = latest start time - earliest start time = 15 weeks - 32 weeks = -17 weeks.
Explanation and Conclusion:
The negative value for the total float (-17 weeks) indicates that the activity cannot be delayed without delaying the project's completion time. In other words, there is no float available for the activity. However, it is important to note that this negative value does not make sense in the context of project scheduling, as float is typically a positive value representing the flexibility in scheduling.
Therefore, the given information is inconsistent or incorrect, as it is not possible to calculate a valid total float based on the provided data.

The earliest start time for the activity is the maximum of the earliest occurrence times for both events. Therefore, the earliest start time = max(8 weeks, 32 weeks) = 32 weeks.
Calculating the latest start time for the activity:
The latest start time for the activity is the minimum of the latest occurrence times for both events minus the activity time. Therefore, the latest start time = min(26 weeks, 37 weeks) - 11 weeks = 26 weeks - 11 weeks = 15 weeks.
Calculating the total float:
The total float is the difference between the latest start time and the earliest start time for the activity. Therefore, the total float = latest start time - earliest start time = 15 weeks - 32 weeks = -17 weeks.
