In 2022 what's the best option for task planner or scheduler?

edit

Hey guys, My name is Eliomar. I am currently figuring out how to implement a task planner or scheduler. I have found some information on the web about task schedulers, like this link https://hal.archives-ouvertes.fr/hal-.... Or like ROSPlan implementation. But there is not seem to be much information about task planners or schedulers in the website.

I know that SMACH is more or less the standard for this, as far as I know from web information that I have read. But almost all the articles or blogs are too old, before 2015. and I wanted to know if there is a ne way to do it or some other alternative in 2022.

Maybe I am not looking in a good way for the information? or it is a topic that does not have much research or pre-made packages? I would appreciate any help, maybe just pointing me in the right direction with links or documents.

Thanks in advance for the help.
