Abstract

Multi-floor layout problems need to be modeled thoroughly considering all significant factors that have effect on the cost of multi-floor layout planning. In this research, the study objective was to develop a preliminary mathematical model of multi-floor layout problems with the goal to minimize the total fixed cost & inter-floor interaction cost. The study solved the numerical case study by extending genetic search codes of preliminary mathematical model. The objective of the study was achieved by adding two new notations of   and representing the number of items going from facility i to facility p and number of barriers with which is faced between location j and q, respectively. Added notations are in both vertical and horizontal directions. Finally Computational results are presented that indicate this model solves the multi-floor layout problems more cost-effective than the previous ones.
