Abstract: In the past few decades along with the developing industrial units, the use of multi floor factories has increased. On the other hand according to the service provided and being in city centers, office buildings, hospitals, universities, ministries etc. represent the most multi floor buildings. One of the most costly procedures which these factories and buildings (which are multi floored) face is the cost of transporting equipment among different departments. These transportations are divided into horizontal and vertical, according to being a multi floor building. For vertical transportation the machine always recommended is an elevator. Placing and elevator is a costly procedure, therefore the number of elevators needed and their locations should be decided. Since 1967 a number of algorithms have been introduced to solve multi floor buildings designing problems, using a lot of simplifying theories based on the large amount of calculations needed. Therefore they are only described theoretically and mathematically, but can't be used in a real setting. In this research we have tried to define an algorithm to solve multi floor designing problem so that it could be used in real settings. All the simplifying theories used for the previous algorithms have been eliminated. Results show that this algorithm to a large extent can be applied to real settings.
