A novel facility layout planning and optimization methodology A B S T R A C T This paper presents a novel factory planning system for real-time on-site facility layout planning (FLP)Two facility layout planning modules are supported, viz., manual and automatic. In this system, a fastmodelling method has been developed where users can construct existing facilities as virtual primitivemodels. A criterion and constraint definition mechanism is provided to define and customize the planningcriteria and constraints to suit specific requi …
