# M.A.R.I.E) PROGRAM. a building has a single elevator serving

### Customer Question

MARIE (M.A.R.I.E) PROGRAM.
a building has a single elevator serving 4 floors. Someone on the forst (ground) floor who wants to ascend pushes a single button (“up”) to call the elevator. Similarly, someone on the 4th floor who wants to descend pushes a single button (” Down”). These two floors each have no other option. Someone on the 2nd or 3rd floor could push either up or down to indicate his or her direction of travel.
Once on the elevator, the passenger can push a button for desired arrival floor (1,2,3,4). A passenger can press/hold a “door open’’ button to signal the doors not to close. The elevator has a safety interlock system. Any floor’s door will not open unless the elevator is stopped at a floor. If the elevator is going up and there are any requests for floors above its current location, the elevator keeps moving in an upward direction until either all upward requests are satisfied or it has arrived at the 4th floor.
Similarly, If the elevator is going down and there are any requests for floors below its current location, the elevator keeps moving in a downward direction until either all downward requests are satisfied or it has arrived at the 1st floor. The elevator will not reverse direction unless related to the (untraveled portion of the) direction it was traveling have been satisfied. Once a request has been handled, it may need to be cleared so later requests like it can be recognized. Analyze the description above and come up with a plan for controlling the elevator. Develop the necessary logic as one or more truth tables. Consider how and where MARIE processor(s) could be used to implement the elevator control system. After you have a plan worked out for the 4th floor case, determine how your plan to would need to be modified to handle a building with more floors. Provide a second answer that will handle a building with more than 4 floors. Finally, create one or more MARIE programs to implement (illustrate; simulate) your plan for elevator control.

Hello, my name is Greg.

Is there any other information you can send to see if I can assist on it this for you? If you have any documents you can upload, you can do so to mediafire.com or box.com and share the link here with us.

If I had a model and could provide that as a model (would have to check files to see if I have one), would that be sufficient or are you seeking a fully written new model document?

Customer: replied 7 months ago.
If the model is like what described in the question, then yes.
