Designer Interview Questions

I would say to let people to enter the floor number into a keypad while they wait for the elevator. This gives them ample amount time to dial in their floor number while waiting instead of having to fight over the keypad after they get into the cramped space inside the elevator. Since most people goes to the same floor every day (assuming this is an office or residential building), there can also be a companion app for employees/residents of the building. It detects that they are waiting for the elevator with a proximity sensor and already knows which floor they need to go to. By pre-entering the floor numbers while waiting, the lift can prioritize which floors to access based on who arrived first and how close these floors are to each other. For example, if the distribution of riders falls into two clusters, then one elevator can take the riders to one cluster of floors, while a second elevator takes them to the second cluster. (This is assuming that there are multiple elevators). Then as the elevator is arriving, it will display the floor numbers it will be accessing. This also reduces the annoyance of the person who jumps in the last minute and chooses a floor arriving ahead of yours. Like my response? Please visit my portfolio at http://www.edmundyu.com

Most of the time, we jump start on solving such a problem from the point of view of lowest floor (street level) problem. Instead, we need to ask some probing questions to understand the scope of the problem. For a 1000 floor building, what is the amount of foot traffic are we talking about (on each floor)? How many elevators are in the building. What is the type of building (Residential, Commercial, Hotel etc.). Once we make some assumptions or get answers to these questions, we can start looking at the complexity of the issue. While it is important to know the people on street level want to go to a certain floor, there are also people who are coming down and people who want to move from some floor to other floors. Hence, the solution needs to allow the elevators to generate its own paths and programmatically decide which direction it will move next. The simplest solution would be to have a place in each elevator lobby for people to enter which floor they want to go, as soon as you enter the floor, the system will display which elevator you need to go and stand. They can either enter the floor number or use NFC based access cards (as suggested by Edmund above). Each of these (multiple) elevators can have numbers (E1/E2?E3 etc.) on each floor. Based on the demand, the elevator logic will decide which elevator goes where and directs people to the respective elevators (to optimise its operation in terms of time, crowd management and electricity consumption). My solution is somewhat a mix of new concepts and some earlier discussions above (as I wanted to build on others ideas and improve the solution).

There is yet insignificant data for a meaningful solution for this Problem statement. mail: newtonpavan33@gmail.com

I think the best way to make 1000 floors elevator is to have manual and automatic controls. For manual control nowadays we use its best as user perspective or to make range selector like we use in android mobile for number selection like for selecting calendar we just use that navigation interface for elevator. If some new member arrive so he/she will easily navigate elevator. And for automatic process I think the fastest and best way is to use face recognition system similar to Window Hello. Before entering to lift the camera above the elevator will scan the face of persons that he/she is the owner, employee or someone else related to the plot or floor. That way restricted floor will be secure and no one can access except the owner / employee / worker (or others new person for limited period).
