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.

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.

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.

Power plants originally designed to be decommissioned at 20–30 years are extending their service life by removing/replacing major power plant components. This requirement is contrary to the original floor and workspace designs engineered for power plants. Feedwater heaters, casks, heat exchangers, and other very large (50′ ±) and heavy (20–100 Ton) components can overcome floor and space restrictions by using a combination of air casters and cranes. This proven methodology saves in excess of 75% of the cost of a standard crane-only operation and significantly reduces the possibility of permanent floor damage. Air caster transport systems are low profile and easily insert under industrial heaters, exchangers, transformers, etc. The casters raise components and carry them across the floor, spreading the multi-ton weight across the surface area without damage to the floor or component. Air casters are frictionless even with the heaviest loads, and significantly reduce ergonomic risk while also providing the benefit of requiring a reduced workforce to move the component across the floor. Controlled drive systems allow a single operator to easily move components omni-directionally without wheels or rails, and into position within .5″ (13mm) accuracy. The air caster methodology for moving heavy loads was referenced as proven effective in existing nuclear plants in the 2004 ICONE paper presented by Tokyo Power. Air casters, often coupled with cranes, significantly lower material handling costs associated with new installation and repair/refurbishment of components up to and over 5000 tons. Air casters operate on normal compressed air and have very few moving parts, resulting in low ongoing maintenance costs.

Abstract With the development of e-commerce and the improvement of logistics requirements, more and more ‘parts-to-picker’ picking systems begin to replace the inefficient ‘picker-to-parts’ picking systems in various scenarios. As the mainstream ‘parts-to-picker’ system, the robotic mobile fulfillment system has been attracting much attention in recent years. In addition to the customer's changing requirements, the rapid response of the picking system to the order is particularly important. In the above context, to seek a breakthrough in the picking system's picking efficiency without increasing the cost of additional equipment, the storage allocation of the pods becomes very important. This article focuses on the dynamic storage allocation of robotic mobile fulfillment system, which has positive theoretical and practical significance. By analyzing the pod storage process of the robotic mobile fulfillment system, a dynamic pod storage allocation model suitable for the robotic mobile fulfillment system is established with the goal of minimizing the pod handling distance. Two dynamic pod storage allocation strategies are proposed for the system. By simulating the picking systems of different scales, the effectiveness of the dynamic storage allocation strategy is verified, which has a certain reference to the operation of the robotic mobile fulfillment system in practice.

Proposed Model

Product allocation is one of the most important duties in warehousing operations. Based on the time and the number of products to put away and retrieve, storage allocation can directly affect the efficiency of a warehouse in terms of both response and operation time. Traditionally, the product storage allocation is done based on the less distance of shipment but focusing on distance may decrease the efficiency of a warehouse in terms of efficient utilization of resources such as warehouse inbound shipping fleet. This paper proposes a storage space allocation model that considers the availability of forklift fleet in a warehouse instead of product shipping distance. The numerical example shows that storing the products based on the proposed model can reduce the volume of forklift fleet idle hours on days with fewer volume of receiving and shipping outs. The proposed model also reduces the overtime working hours on days with higher volume of receiving and shipping out products.

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).
