I do not know in which field your terms are applied. But generally speaking
"event driven" موجه أو موجهة بالإحداث
"schedule driven" موجه موجهة بالتوقيتات

In programming, system response can be generated either by an event such as a mouse clicking, window sizing or by a specified period of time.

The same can be applied in other systems .In Power Management, system response can be obtained either by an event (when a certain a value is reached or by mere timing.
Example: In event-initiated response I will cut electricity when a voltmeter reads 10 volts (regardless how long time it takes to reach this value) while in schedule-initiated response I will cut electricity each 2 hours (regardless how much volts it reads)..
I guess
