Abstract:
Facility Layout Problem (FLP) is known as one of the classical problems in industrial engineering which have acquired high attractiveness to researchers. Therefore, in this study, a practical mathematical model is formulated and solved
In order to have a real and practical model, robust optimization is applied to FLP. Therefore, it is supposed to have dynamic values for departments' dimensions. This assumption is very critical to generate an effective and acceptable layout. We consider that each dimension of a department can be changed in a given interval. Due to this assumption, we introduce two new parameters which are called width and length deviation coefficients, respectively. These parameters help us to have a robust mathematical models for FLP.
Moreover , to solve this problem, a comprehensive definition is proposed for a robust layout and according to this definition a mathematical model is presented. This mathematical model is a mixed integer programming model. Furthermore, we solve some benchmarks in literature by the proposed model. At the end of this study, a sensitive analysis is presented to analyze different changes of some important parameters of the model
