In some jobs I need to model no-earlier/no-latter than time constraints separate or in combination to date constraints but most software do implement date constraint mixing it with time.
For example because of hot whether conditions some concrete pouring shall start after 4pm but not latter than 7pm no matter on what day, that would be a pure time constraint. In other occasions the constraint can be; do not start before certain date because of access limitations by Owner but also the time constraint about the start hour shall be satisfied. Maybe the activity because of some driving logic that moves it beyond the date can theoretically start on next day satisfying the date constraint but at an hour that breaks the time constraint.
How can I model the following scenario:
- Date Constraint: Start no earlier than next Wednesday
- No Earlier Time Constraint: Start no earlier than 4pm
- No Latter Time Constraint: Start no latter than 7pm
Best regards,
Rafael
