A facility that is indispensable but not preferred located nearby is called a NIMBY facility. For smoking areas and nursery schools among them, users want to shorten the use distance, but those who do not use want to secure an separation distance. This research calls such facilities NIMBY facilities of confliction type, and examined their optimal placement by taking smoking areas as an example. The results are as follows. By distributing smoking areas appropriately according to demand, the moving distance may be reduced from the balance between the buffer due to the separation distance and the available space. However, as the number of facilities increases, it becomes necessary to secure a separation distance between facilities, and as a result, the movement distance increases. Therefore, the location of the NIMBY facilities of confliction type is not a matter of simple aggregation or distributed arrangement, but optimization taking into consideration of the separation distance between facilities is necessary.
