(Adil, Turkay et al 2005) Tree representation of the layout problems Essential feature of layout problems are characterized in tree representation diagram as shown in fig. From a layout point of view, this situation requires the solution of the dynamic layout problem (DLP). To operate efficiently under such environments, the facilities must be adaptive to changes of production requirements. It changes from one production period to another. Under a volatile environment, demand is not stable. Dynamic facility layout problem (DFLP) When material flow assumes varied path between departments during the planning horizon, the problem becomes the dynamic facility layout problem (DFLP). The static facility layout problem (SFLP) approach generally assumes that flow between machines, product demand, and levels of product mix are constant during the planning horizon. The facility can be manufacturing plants, administrative office buildings, or service facilities,( Alan R, jin et al 2005). Static facility layout problem (SFLP) The static facility layout problem (SFLP) is the determination of the most efficient arrangement of departments within a facility with scope of improvement only within the layout boundary.
Facility layout problems are classified into two categories, static facility layout problem (SFLP) and dynamic facility layout problem (DFLP).
Over the period of several couple of decades, FLP have been studied by several researchers to a significant extent for establishing optimum and universal method to solve the problem and a large variety of solution procedures based on algorithms have been proposed. Classification of Facility Layout Problems Determining the most efficient arrangement of physical departments within a facility is defined as a facility layout problem (FLP) (SMTF Ghomi et al, 2011). Classification Of Facility Layout Problems The purpose of this literature review is to explore the general facility layout problem, the dynamic facility layout problem, the models that have been used to represent the facility layout problem and the algorithms that solve the models.
