Facility layout is integrated planning of the flow of a product in an operating system to obtain the most effective and efficient interrelation between workers, materials, machinery, and equipment as well as handling and transferring materials. A company engaged in furniture manufacturing has a problem in its production process, namely, the distance between machines is too far so that it affects the cost of handling materials. Distant workstations are found on profile machines, milling machines, measuring machines, cutting machines. Therefore, improvements must be made to the layout of facilities on the production floor so that facility layout is efficient and material handling costs are reduced. The problem-solving approach used is the Graph Method and CRAFT Algorithm. The results of the research show that material handling costs are reduced by 7.58% or Rp. 17,765 using the CRAFT algorithm.

PT. AP Tbk. A company engaged in the integrated textile industry, one of the companies that produce various types of high-quality production in yarn manufacturing. Problems that occur at PT. AP Tbk. Superior in yarn processing facilities. In the layout production facility has not been used optimally, location settings are not optimal. found a step back that caused the distance to be far away. For that, it is necessary to restructure the layout of these machines so that the total distance of material handling is faster. Based on the results of research and data processing using a systematic Layout Lay out method, the layout is more efficient when compared to the layout before repair. With the SLP method, two alternative layout locations are produced which can minimize the distance of the material flow and the cost of material handling. Layout 1 can save a distance of 45 meters by issuing material handling costs of 3881.52 rupiah from the initial layout, while layout 2 can save a distance of 57 meters by looking for material handling costs of 4744.08 rupiah from the initial layout. Thus, layout 2 is more recommended so that activities and production results are more optimal and handling of cost material becomes smaller.

In the facility layout decisions, the previous general design principle is to minimize material handling costs, and the objective of these old models only considers the costs of loaded trip, without regard to empty vehicle trip costs, which do not meet the actual demand. In this paper, the unequal-sized unidirectional loop layout problem is analyzed, and the model of facility layout is improved. The objective of the new model is to minimize the total loaded and empty vehicle trip costs. To solve this model, a heuristic algorithm based on partheno-genetic algorithms is designed. Finally, an unequal-sized unidirectional loop layout problem including 12 devices is simulated. Comparison shows that the result obtained using the proposed model is 20.4% better than that obtained using the original model.

Space Requirements

Facility layout and flexible automation are two approaches for reduction of material handling costs and space requirements in a machining facility that have always been implemented independently of each other. This paper describes an integrated approach to compaction of existing machining facilities using machine grouping algorithms and multi-function machining centers, also referred to as Flexible Machining Modules (FMMs). First, we decompose a facility into a network of layout modules to reduce product travel distances and simplify material flow control. Then, subject to design feasibility, we identify those sets of machines in each module that could be replaced by multi-function FMMs that could be linked into a Flexible Machining System (FMS). The proposed approach uses a combination of pattern recognition and graph theory algorithms utilized for facility layout. The paper concludes with a description of a validation study conducted in an aerospace machining jobshop.

The storage allocation in warehouse is about of deciding the corresponding areas in which the products must be allocated. It can be made using different techniques to stablish the specific position for the products. Some applications provide solutions and evaluate results independently, allowing the identification of its potential in warehouses. This paper presents the application of a storage allocation model in a food company considering several products in a defined time horizon. The algorithm identifies the operation area and the corresponding spaces that are required for the products allocation, aimed to reduce holding and material handling costs. As a result, the application of the algorithm produces a complete product allocation in each period and improves the cost efficiency in the warehouse.

The Cost

Factors that influence the amount of material handling costs are the distance of material movement, methods, and tools (equipment) used. The distance of material movement is strongly influenced by the layout of the production facility. The new layout design using the SLP method is expected to reduce the distance of material or product movement in PT. A B C. From the analysis results obtained the total distance of material transfer at the initial layout of the production process at PT. ABC of 1761 meters / month with material handling costs of Rp. 315,390,000.00 / month. Then an analysis of the use of material transport equipment results in the replacement of a crane with a sloping plane to connect the production machine. So the cost of material handling using the inclined plane becomes Rp. 0. The use of sloping fields can only be used on certain production machines. By using the Systematic Layout Planning (SLP) method, there are 3 alternative layouts produced. The most optimal alternative layout is alternative layout 3 with monthly material handling cost savings of Rp. 68,100,000.00 or 21% of the initial material handling layout cost.

Alternative Designs

Good equipment and product design are meaningless if there is no good layout planning. Problems owned by PT. Pilar Kekar Plasindo occurs in the production of small polyethylene. This is because small polyethylene production has large material total transfer distance. Small polyethylene problems include the distance between stations, cross-movement, backtracking, and the broken machine that is still placed in the production section. These conditions make the material handling costs and distance large. Therefore, this research aims to produce a layout design of production facilities that can minimize the distance and cost of material movement. The method used in this study is Systematic Layout Planning (SLP). Three alternative designs were compared, and the second proposed facility layout was chosen because it can reduce the total cost of material transfer by 68.3% and reduce the distance of material transfer by 59.6% from the initial facility layout.

This paper deals with dynamic facility layout problem (DFLP) in a plant which is concerned with determining the best position of machines in the plant during a multi-period planning horizon. The material handling costs and machines rearrangement costs are used to determine the best layout. In addition to positions of machines, the details of transportation such as type of transporters and sequence of transportation operations have a direct effect on MHC. Therefore, it is more realistic to consider the transportation details during DFLP optimization. This paper proposes a new mathematical model to simultaneously determine the best position of machines in each period and to plan the transportation operations. Minimizing sum of MHC and MRC is considered as the objective function. A new hybrid meta-heuristic approach has been developed by combining modified genetic algorithm and cloud-based simulated annealing algorithm to solve the model. Finally, the proposed methodology is compared with two meta-heuristics on a set of test problems.

Dynamic facility layout problems involve devising the optimal layout for each different production period. This article studies unequal-area dynamic facility layout problems under fuzzy random environment to minimize the sum of the material handling costs and rearrangement costs. For a more general situation, a novel model of unequal-area dynamic facility layout problems is proposed on the basis of fuzzy random theory, in which uncertain demands are characterized by fuzzy random variables. Unequal-area dynamic facility layout problems are one of the non-deterministic polynomial-time hard problems. Therefore, a hybrid particle swarm optimization and simulated annealing algorithm is innovated to solve the proposed unequal-area dynamic facility layout problems model under fuzzy random environment, in which the shapes and areas of facilities are changed dynamically. Two facility-swapping methods and two local search methods help hybrid algorithm escape from local optima, allowing a more reliable solution. Moreover, a new shifting method is developed to prevent the spatial overlapping between adjacent facilities and save material handling costs. The performance of the hybrid algorithm is confirmed by some test problems available. Finally, the proposed method is extended to a facility layout planning of a new aircraft assembly shop floor. Computational results show that the efficiency and effectiveness of the proposed method, in sharp comparison with other approaches.
