Start and end time as a planning variable.

[aayuwush]

Can you make timefold add start and end time of a task based on its priority and time to complete the task? There will not be a fixed start and end time due to difference in completion time. But to make a planning variable you need fixed start and end time like time slot. thank you!

Consider using the chained through time pattern: https://docs.timefold.ai/timefold-solver/latest/design-patterns/design-patterns#chainedThroughTimePattern

In summary, each "worker" has a time when they begin/depart to their first task, and the task's start and end time are shadow variables, depending on the previous task end time and current task start time respectively. See the vehicle routing quickstart for an example.
