As a campus that has a maritime mission, Madura State Polytechnic has made a master plan for campus development by building a shipyard. This is also supported by the campus located on the beach. In preparing the shipyard, facilities are very important, so a careful planning is needed in doing the layout. In this paper, we will propose a layout process based on the production flow pattern of shipbuilding, comparison with the layout design using the CORELAP algorithm method, by calculating the percentage value of material handling and planning tools and facilities for the POLTERA shipyard. The facility layout planning obtained new and repaired building types with an area of ??5.16 hectares and a layout design with an L layout production flow pattern. The design had a material handling percentage value of 21.62%.

Facility layout design is becoming more challenging as manufacturing moves from traditionally emphasised mass production to mass customisation. The increasing demand for customised products and services is driving the need to increase flexibility and adaptability of both production processes and their material handling systems. A holistic approach for designing facility layouts with optimised flows considering production and logistics systems constraints seems to be missing in the literature. Several tools, including traditional methods, analytic hierarchy process, multiple-attribute decision making, simulation, and optimisation methods, can support such a process. Among these, simulation-based optimisation is the most promising. This paper aims to develop a facility layout design methodology supported by simulation-based optimisation while considering both production and logistics constraints. A literature review of facility layout design with simulation and optimisation and the theoretical and empirical challenges are presented. The integration of simulation-based optimisation in the proposed methodology serves to overcome the identified challenges, providing managers and stakeholders with a decision support system that handles the complex task of facility layout design.

Facility layout design problem considers the departments’ physcial layout design with area requirements in some restrictions such as material handling costs, remoteness and distance requests. Briefly, facility layout problem related to optimization of the layout costs and working conditions. This paper proposes a new multi objective simulated annealing algorithm for solving of the unequal area in layout design. Using of the different objective weights are generated with entropy approach and used in the alternative layout design. Multi objective function takes into the objective function and constraints. The suggested heuristic algorithm used the multi-objective parameters for initialization. Then prefered the entropy approach determines the weight of the objective functions. After the suggested improved simulated annealing approach applied to whole developed model.

Facilities Layout

The weighted maximal planar graph (WMPG) appears in many applications. It is currently used to design facilities layout in manufacturing plants. Given an edge-weighted complete simple graph G, the WMPG involves finding a sub-graph of G that is planar in the sense that it could be embedded on the plane such that none of its edges intersect, and is maximal in the sense that no more edges can be added to it unless its planarity is violated. Finally, it is optimal in the sense that the resulting maximal planar graph holds the maximum sum of edge weights. In this chapter, the aim is to explain the application of planarity in facility layout design. The mathematical models and the algorithms developed for the problem so far are explained. In the meanwhile, the corollaries and theorems needed to explain the algorithms and models are briefly given. In the last part, an explanation on how to draw block layout from the adjacency graph is given.

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.

Abstract – Unplanned layout and inefficient material flow between work units can lead to increased cost. PT Transplan Indonesia's current material flow path is inefficient with material flow distance 115.5 meters and material handling cost that has not been taken into account. This study aims to find out how big the role of facility layout design in cutting the distance of material transfer and pressing the cost of material handling. The method used in this research is Systematic Layout Planning (SLP) approach, which is comparing the distance of material transfer between initial layout with proposed layout. The results of this study indicate that the distance of the material flow path on the production floor with proposed layout changed to 71,7 meters, with material handling cost per meter reduced from Rp. 1,105,954 to Rp. 712,402 or decrease as much as 35%. Based on the results of the research, the layout of the proposal is considered more effective and efficient because it can reduce the distance of material transfer and reduce the cost of material handling on the packing/shipping floor.Keywords: Layout Design; Material handling cost; Systematic Layout Planning (SLP)

The Given

Facility layout problems (FLPs) are concerned with the non-overlapping arrangement of facilities. The objective of many FLP-based studies is to minimize the total material handling cost between facilities, which are considered as rectangular blocks of given space. However, it is important to integrate a layout design associated with continual material flow when the system uses circulating material handling equipment. The present study proposes approaches to solve the layout design and shortest single loop material handling path. Monarch butterfly optimization (MBO), a recently-announced meta-heuristic algorithm, is applied to determine the layout configuration. A loop construction method is proposed to construct a single loop material handling path for the given layout in every MBO iteration. A slicing tree structure (STS) is used to represent the layout configuration in solution form. A total of 11 instances are tested to evaluate the algorithm’s performance. The proposed approach generates solutions as intended within a reasonable amount of time.

Purpose In today’s competitive market, product demand and its mix frequently vary due to various uncertainties, which thus imparts the overall manufacturing cost. Furthermore, uncertainties also impart the layout design in manufacturing industries in the long run. Therefore, the layout design needs to capture the possibility of uncertainties, and these uncertainties must be captured while designing the layout of a facility. Hence, an efficient facility layout design minimizes the manufacturing cost and lead time. The purpose of this paper is to propose a cellular layout design for a tower manufacturing industry. Design/methodology/approach The paper develops an embedded simulated annealing-based meta-heuristic to solve proposed cellular layout under different scenarios considering single and multi-time periods for tower manufacturing industry. A comparative study is also performed to analyze comparison among static cellular layout, a dynamic cellular layout or a robust stochastic cellular layout for the tower manufacturing industry. Findings The current layout of the industry is a process layout. Here, the layout for a tower manufacturing industry is proposed under SCFLP, DCFLP and RSCFLP. The proposed models and solution methodology is tested using six scenarios with different combination of time periods. Lastly, OFV value obtained for all the scenarios is compared, and it is found that RSCFLP outruns other SCFLP and DCFLP for a tower manufacturing industry. Based on the above study, it is also concluded that RSCFLP is an efficient and effective layout in tower manufacturing industry. Originality/value The paper proposes a cellular layout design for a tower manufacturing industry. The cellular layout design is found to be preferred over the traditional layout as it reduces material handling cost, manufacturing lead time and hazards. Moreover, it enhances productivity and quality.

Abstract. The facility layout is a strategic design that is used for a long time. All manufacturing industries must pay attention to the right layout to increase the productivity of the industry. A prayer paper manufacturing industry located in the Tanjung Morawa area, Medan has an error in the placement of raw materials and the placement of production machines, so that the distance from the temporary warehouse to the printing and cutting work stations is far apart, causing high material handling costs. Seeing these problems, research was carried out to improve the layout of the facilities and redesign. The method used for this research is Systematic Layout Planning (SLP), which is one of the methods used to regulate a workplace in a factory by using two areas with high frequency and logical relationships with each other. And the Computerized Relative Allocation of Facilities Technique (CRAFT) Algorithm is a repair program, which is a program that looks for optimal design by making gradual improvements to the layout. CRAFT evaluates the layout by interchanging departmental locations. Inputs required for the CRAFT algorithm include initial layout, data flow or frequency of movement, cost data per unit distance, and the number of departments that do not change or remain. The CRAFT method is usually applied using Quantitative Systems (QS) software. By comparing the layout between SLP and CRAFT, the optimal result is obtained using the SLP method by reducing the distance between departments by 1.407 meters or a distance efficiency of 39.91%.

Initial Layout

PT. Adhimix Precast Indonesia is engaged in the construction sector by producing concrete and construction. Layout design is needed so that the existing land can be utilized optimally and material transfer is more effective and efficient. This can affect the distance and time of the transfer so that the cost of moving can be minimized. In practice, the company's trajectory condition only has one path (trajectory) for alternating current and crossing production lines, so it is considered inefficient to move both goods and workers, coupled with the existence of land that is not used properly, therefore improvements are needed to the production floor layout. in order to minimize the cost of moving goods and have a definite path (trajectory). Systematic Layout Planning (SLP) is a method for redesigning a layout (re-layout) based on the results of distance optimization and Material Handling Costs (OMH). The amount of OMH in the initial layout (now) is Rp. 2,614,200 with a total track distance of 39.82m and OMH in the proposed layout with a total track distance of 19.17m, the result is Rp. 1,534,200, this proves that the proposed layout can be applied because there is a decrease in total OMH by 35.44% or Rp. 926,580. PT. Adhimix Precast Indonesia bergerak di bidang pembangunan dengan memproduksi beton dan konstruksi. Perancangan tata letak diperlukan agar lahan yang ada dapat dimanfaatkan dengan maksimal dan pepindahan material lebih efektif dan efisien. Hal ini dapat mempengaruhi besar jarak dan waktu perpindahan sehingga besar biaya perpindahan dapat diminimalkan. Pada pelaksanaannya kondisi lintasan perusahaan hanya memiliki satu jalur (lintasan) untuk arus bolak balik dan persilangan alur produksi maka dianggap tidak efisien untuk dilakukan perpindahan baik barang maupun pekerja, ditambah dengan adanya lahan yang tidak dimanfaatkan dengan baik oleh karena itu dibutuhkan perbaikan pada layout lantai produksi agar dapat meminimalkan biaya perpindahan barang dan memiliki jalur (lintasan) yang pasti. Systematic Layout Planning (SLP) merupakan metode untuk membuat perancangan ulang suatu layout (re-layout) berdasarkan hasil dari optimalisasi jarak dan Ongkos Material Handling (OMH). Besar OMH pada layout awal (sekarang) adalah Rp 2.614.200 dengan total jarak lintasan 39,82m dan OMH pada layout usulan dengan total jarak lintasan 19,17m didapat hasil sebesar Rp. 1.534.200, hal ini membuktikan bahwa layout usulan dapat diterapkan karena terjadi penurunan total OMH sebesar 35,44% atau Rp.
