Abstract
This paper presents a new approach to the coordinate type facilities layout problem. The site and each facility location are represented in a coordinate system. The objective is to minimize the total cost incluing the material handling cost and site areas cost, and maximize a closeness rating measure. We present "locatable edges" for the facility arrangement in order to restrain the search space. The results indicate that the model does an excellent job for the facilities layout problem with unequal areas as well as with equal areas, and that the ability to handle large scale problems is also improved.
