Optimization of Warehouse Layout for the Minimization of Operation Times
Lecture Notes in Computer Science, 2021
Warehousing management is essential for many companies involved in the supply chain. The optimal arrangement and operation of warehouses play important role in companies, allowing them to maintain and increase their competitiveness. One of the main goals of warehousing is the reduction of costs and improvement of efficiency. Determination of the ideal warehouse layout is a special optimization case. In the article, a procedure is applied to the optimization of the allocation of bins in an automated warehouse with special characteristics. The initial layout of the warehouse, as well as the automated platforms constraints the search, as well as define the time needed to move goods inside the warehouse. The definition of time needed to move goods, with the analysis of historical data, allows the definition of a mathematical model of the operation of the warehouse. Using that model, an optimization procedure based on the well-known hill-climbing algorithm is defined. Experimental results show increments in the efficiency of the warehousing operations.
Space optimization in warehouses logistics
2014
Industrial warehouses are typically composed by multi levels scaffolds holding pallets, each pallet carrying one or more manufacturing item. The paper introduces the problem of the wasted space in industrial warehouses and describes the algorithms implemented in a simulation software able to suggest how to organize the storage of the manufacturing items. The proposed software uses effective and efficient search algorithms to minimize the overall storage lost space. The general structure of the numeric platform and the logics of the solver algorithms are described together with the strategies adopted to reduce the computation time. Typical results obtained in an industrial environment working in the plastics sector are presented and discussed.
Layout evaluation of large capacity warehouses
Facilities, 2007
PurposeThe purpose of this article is to present a model to estimate and evaluate the operational costs of alternative layouts for large capacity warehouses or distribution centers with a large variety of goods.Design/methodology/approachThe proposed model is based on time and resources studies per each of the basic activities on a warehouse operation. For validation purposes, the proposed model was applied on a perishable goods warehouse in Mexico. The output data was compared to actual data. Performance measures were operational costs and average picking time.FindingsIt was found that the proposed model is robust, flexible, simple and easy to be implemented. The model was used to evaluate two new alternatives of layout and operations of the same warehouse. It was found that the option with the layout with docks on long opposite sides of the warehouse and the operation without a separate picking zone minimizes operational costs.Research limitations/implicationsThe richness of the m...
Decision making strategies for warehouse operations

The paper presents issues related to design and organization of the warehouse process. Draws attention to problems of modelling logistics facilities and processes occurring in them. Paper also points out the essence of correct operation of warehouses and associated with this risks for supply chain. Warehouse processes have been properly defined and divided into smaller components, like: phases of process, activities, sets of procedures, procedures or working movements. Paper presents various possible configurations of warehouse processes, which were named as warehouse strategies. Warehouse process strategy is a part of warehousing. It determines the sequence of warehouse operations. These operations are related to internal transport, cargo form transformation and cargo buffering. In paper it is noted that the warehouse strategy depends on the several technical and organizational factors and is associated with a certain probability. This probability can be estimated based on data ana...
Analytical Model for Optimum Warehouse Dimensions
Research in Logistics and Production, 2015
Warehouses are essential components of any supply chain in terms of customer service and cost levels. Warehouses are one of the important players in the success or failure of businesses from not only the customer service levels perspective but also the cost perspective. Warehouses, as one of the important components of supply networks, should be continually improved from design and operation perspectives to increase the performance. All efforts and solutions regarding the performance improvement are important and complex. In other words, warehouses should operate effectively in terms of the costs and technical performance that are determined during the design phase of warehouses. There are a few studies in the literature regarding the calculations of the optimum dimensions of a warehouse along the x, y, and z directions. In this paper, an analytical model is proposed to achieve the optimum warehouse dimensions in terms of the number of stocking zones along each of three dimensional ...

Article History: Warehousing is the glue for supply chain coordination. This function has become more important in dry port management in landlocked countries. Ethiopia is one of the landlocked countries use dry ports to mitigate related challenges. Modjo dry port is one of the largest and currently more than 95% of freights flow and first dry port. The flows of unstuffed containers in terminal increase the influences the warehouse operation, the existing dedicated volume of warehouse becomes beyond the dedicated capacity of the warehouse. The layout of the warehouse is not standardized for the flow of freight inside the warehouse. Therefore, the study intends to propose the modified scenarios for the existing warehouse layouts for the reduction of congestion from the warehouse and this, in turn, reduces congestion from the terminal of the dry port. The primary and secondary data were collected to accomplish the study. The primary data were collected by field observation, field survey and secondary data was collected by documented data of dry port. Using analytical hierarchical procedure the Modjo dry port should have to use the layout IV, II, I and III those have the composite weight of 31.63%, 29.199 %, 26.997 %, and 12.17% respectively as well as AHP factors like suitability for travel, store space, proximity to inspection area, and accessibility for forklift scores 7.93%, 51.47%, 5.41%, and 35.19% of priority vector respectively for the selection of alternative layouts. Therefore, Modjo dry port and terminal should have to use pallet racks as per the alternative layout proposed.
Warehouse Optimization: Energy Efficient Layout and Design
Mathematics
It has been widely demonstrated by many research works that the distribution of a factory can condition its productivity. Because of this, a factory in Santiago, Chile, asked the authors for advice to evaluate the current situation in the company and what alternatives could be proposed to improve performance by increasing productivity without incurring too high costs. Among the most important requirements requested was a study of the current design of the raw materials warehouse within the plant since this is a main pillar in the design of the plant. For this purpose, the current layout ws analyzed and alternative designs were proposed under two scenarios: use the same area that is currently available or make the design from scratch considering land purchases to build the warehouse. In order to give a precise answer to many possible design decisions, formulations were developed and deduced to calculate the optimal dimensions of the warehouse, and qualitative criteria were incorporat...

Methods of Increasing Warehouse Capacity in an Enterprise: Case Study
5th EAI International Conference on Management of Manufacturing Systems, 2021
Warehousing of goods is one of the most important subsystems of the logistics system in a company. It covers the storage of goods of various types and properties for various periods of time. A warehouse is a place where multiple activities are carried out, depending on the warehouse function and position within the logistics system of a company or in its supply system. Several authors have presented the characteristics of warehouse and warehouse systems in their publications, or they deal with issues regarding solutions to specific problems related to the warehousing of goods. The technical literature deals with issues concerning the warehouse design [1, 2], warehouse and rack systems [3], warehouse space [4], warehouse layout [5-7], warehouse manipulation [8], costs, performance [9], etc. An important parameter of a warehouse is the warehouse capacity. The warehouse capacity depends on several parameters, primarily on the properties of goods (products), the storage unit size, the type of the storage facility and the handling (manipulation) technology, the storage method, and the warehouse layout [10]. The warehouse capacity is a parameter that may be expressed in various forms [11]. We distinguish between the warehouse static capacity and the warehouse dynamic capacity. The warehouse static capacity relates to the number of storage places for goods at a standstill that is available for removal and subsequent shipment [12].
