Scheduling analysis of real-time systems is like making a plan. It means working out when things should happen, so that they can happen in the right order and at the right time. For example, if you're going on a long car trip, you might make a plan so that you can arrive at your destination on time. Scheduling analysis for real-time systems is similar - it helps make sure that activities are done in the right order, and at the right time, so that the system works correctly.
