You can purge unused resources (like schedules) from your model by clicking on the little recycle bin icon near the bottom left corner of the appropriate tab.
Once you've purged that unnecessary data, you shouldn't see those errors.
@ljbrackney Can users see which schedules are unused before they purge them?
I don't believe the UI highlights unused schedules. You could probably whip up a reporting measure to poll the model for unused resources.
The standard OpenStudio report has a "Schedule Overview" section at the bottom. It shows Ruleset Schedules used in the model. If you expand the table it shows you the use count for each schedule. Unused schedules won't show up here. When purging schedules make sure you first purge unused SpaceTypes or they will prevent some schedules from being purged. You could also use the Remove Orphan Objects and Unused Resources measure.

Are you using OpenStudio, or EnergyPlus directly?
In EnergyPlus, you can add the line:
to your IDF, and it should give you the name of your unused schedule.
If this is an OpenStudio question, you can purge unused resources in the Application. That's not a bad idea to slim down your OSM too.
i am using the open studio program and i don't know where i have to write this order Output:Diagnostics,DisplayUnusedSchedules;
@ipetidis there is a measure to Add Output Diagnostics. One of the argument choices is "DisplayUnusedSchedules".
