Utilization factor is like a way to measure how much a thing or a place is being used.
Let’s imagine that you have a bucket of toys to play with. If you play with one toy for a long time, it means that the toy has a high utilization factor because it's being used a lot. But if you only play with the toy for a little while and then switch to another toy, it means that the toy has a low utilization factor because it's not being used as much.
The same idea applies to other things you might use or places you might visit. For example, a playground might have a high utilization factor if lots of kids are playing on it all day long. But a library might have a lower utilization factor if there aren't too many people visiting it.
Utilization factor is important for things like businesses or transportation systems, like buses or subways. If there are too many buses running around, but not enough people are riding them, the buses might have a low utilization factor, and they might be wasting resources.
So, if you ever hear the term utilization factor, just think of it as a way to measure how often something is being used, so we can make sure we're using our resources efficiently.
