    is it possible to control a 3 level elevator (with inner and outer request buttons) without a microcontroller? is there other alternatives?

    The best option will be a microcontroller, as I see it. But you can actually use many types of logic. Like discrete gates, AND, OR, XOR etc.

    Just think about it. They had elevators in 1920, right? Did they have microcontrollers? No they didn´t, they could do almost anything with enough relays.

    I made one for a friend to move laundry between three floors using only CMOS logic ICs. Make a flow chart and it gets pretty simple. You need switches at each floor so the logic knows where the platform is.

    so how do you make a relay circuit for the elevator? any ideas? what kind of relays do i need for the best results?

    Read the thread on "dumbwaiter control system". Be aware that this is for a dumbwaiter lift system and is not meant for passenger loads. Elevators contain multiple redundent safety systems and "lift" systems do not.
