It's a bit hard to analyze your proposed solution because the signals you generate, such as "UP" and "DOWN", aren't defined by your specification, in which you have a 3-bit signal representing five defined conditions. You also say that you've somehow taken the three input signals, R3, R2, and R1. How have you done this? We are not mind readers, we have to examine your logic based on the information you provide (and, keep in mind that the person that grades your work will be in the same situation).

It correspond to a Elevator FSM. The input R1, R2, R3 are the request made in every floor. For example: when Elevator is in S1 (Floor 1) is requested for S3 (Floor 3), scale two floors (UP2). The input signal based on another example of mealy machine, I divided in two bits: R1 R0. I hope thats good enough !

But what does that mean?

You have THREE inputs. How are you mapping those to your TWO bits?

And why are you using the name R1 for two different things -- that just about guarantees confusion?
