Facility layout problems have been generally solved either hierarchically or integrated into other phases of plant design. In this paper, a hybrid method is introduced so that clustering and facilities layout can be simultaneously optimized. Each cluster is formed by a group of connected facilities and selection of the most appropriate cluster configuration is aimed. Since exact method by MIP i...

 This paper present unequal-sized facilities layout solutions generated by a genetic search program named LADEGA (Layout Design using a Genetic Algorithm). The generalized quadratic assignment problem requiring pre-determined distance and material flow matrices as the input data and the continuous plane model employing a dynamic distance measure and a material flow matrix are discussed. Computa...

A construction site represents a conflux of concerns, constantly calling for a broad and multi-criteria approach to solving problems related to site planning and design. As an important part of site planning and design, the objective of site-level facility layout is to allocate appropriate locations and areas for accommodating temporary site-level facilities such as warehouses, job offices, wor...

A bay configuration arranged along a central spine and served by an automated monorail material handling system are common designs for the layout and material handling system in new semiconductor wafer fabrication facilities. This paper investigates the facility design problem in semiconductor fabrication facilities and proposes a procedure to determine the optimal spine layout design given a d...

In this study, optimal layout design approach was used to solve problems related to site layout design of agricultural facilities such as refrigeration house, grading and packing house and warehouse. A basic program to support the rational construction of such facilities using Simulated Annealing (SA), one heuristic algorithm and one solution for combinatorial optimization problems, was coded i...

geographic information systems (gis) are one of the fastest growing computer-based technologies of past two decades, yet, full potential of this technology in construction has not been realized. based upon gis capabilities, construction site layout is one of the areas that gis could be applied. the layout of temporary facilities (tfs) such as warehouses, fabrication shops, maintenance shops, co...

Proper arrangement of facility layout is a key issue in management that influences efficiency and the profitability of the manufacturing systems. Parallel Row Ordering Problem (PROP) is a special case of facility layout problem and consists of looking for the best location of n facilities while similar facilities (facilities which has some characteristics in common) should be arranged in a row ...

LayOPTTM is an innovative facilities layout analysis and optimization software package which can be used by layout planners and engineers in the optimal solution of single and multiple floor facility layout problems. LayOPT is ideal for the re-design of the overall layout for an existing facility or the development of a block layout for a new building. It can be applied to manufacturing, wareho...
