Optimization of Warehouse Management in the Specific Assembly and Distribution Company: a Case Study

This paper discusses the optimization of warehouse management in the assembly and distribution company. As part of complex logistics system, warehouse management plays a significant role in every company, connecting the areas of storage, material flow, production, record keeping and dispatch with the company´s economic objectives. It also has a significant impact on business operations and can be of an important competitive advantage. It may be argued that well-managed logistics, including a continuous material flow, cost minimization as well as overall streamlining of individual processes associated with manufacturing of products, are powerful strategic tools for companies and lead to their strong market position. It is almost an imperative for them to use modern knowledge in this area and strive for improvement. After the introducing chapters, paper includes an optimization proposal using particular methods of multi-criteria evaluation of variants which consists of determining the criteria for variants evaluation, developing the basic multi-criteria matrix and selecting as well as applying the specific method for final evaluation (in our case, the comparison with WSA and TOPSIS methods has been carried out). Final part of the paper outlines the most appropriate option regarding the introduction of an automatic identification system to optimize the warehouse management system

Design of Performance Indicators in Warehouse Management

To maintain the continuity of product flow in the supply chain system, good warehouse management is needed. Dynamic market conditions are able to cause instability in the product flow. Moreover, there are many disruptions occur as technology continues to develop in Indonesia. This instability will indirectly affect the warehouse performance in a company. So, to minimize the effects of instability, it is necessary to design indicators that are used as a reference for designing mitigation strategies and as a controlling tool so that the company's growth is relevant to the objectives that have been created. In addition, these indicators can be used as a benchmark to improve the warehouse regularly.  So, this research aims to design performance indicators in warehouse management that can be used as a measurement reference to increase warehouse productivity. The result showed that there are 17 validated indicators which are categorized into 5 dimensions. These dimensions are 4 cost dimension indicators, 4 productivity dimension indicators, 3 quality dimension indicators, 4 time dimension indicators, and 2 utilization dimension indicators

Evaluation of lean practices in warehouses: an analysis of Brazilian reality

© 2020, Emerald Publishing Limited. Purpose: This article aims to investigate the most applied lean warehouse practices in Brazilian warehouses. Design/methodology/approach: To perform this research, three phases were conducted: a literature review, a multiple case study, and an analysis of lean warehouses practices implementation by an engineering committee. Thus, both qualitative and quantitative approaches were used. Additionally, the study has an applied nature, with an exploratory and descriptive character. Findings: Results showed that regardless of the type of criterion used, the most implanted practices are those that do not involve investments in technology. On the other hand, practices like RFID and Cross Docking systems were not found in any of the operations, which shows numerous possibilities for improvement. Originality/value: The main contribution of this article is to initiate a debate about the management and productivity of Brazilian warehouses, a theme still little explored by the academic community despite the importance that the logistic scenario represents for Brazil as an emerging country and leader in Latin America, participating actively in several global supply chains

Improving efficiency in a hybrid warehouse: a case study

Logistics has assumed a determining position in the supply chain of each organization. This paper concerns the work carried out in a bus manufacturing organization with the aim of improving efficiency in its hybrid warehouse. A hybrid warehouse could be considered as one that mixes several different activities (reception, storage area, picking, shipping, supply to production lines and production preparation tasks) and brings together many different materials or raw materials and components. This factor led to the appearance of innumerable management methods to improve employee performance. These are intended to meet the needs of their customers, from the motto "do more with less". The work developed in a hybrid warehouse allows to detect logistic complaints related to communication failures between employees, the reduced efficiency in the activities like the check of raw materials or components and respective picking, the lack of space for their reception and storage, and the non-compliance of the FIFO stock management system. It is imperative that organizations can redefine internal spaces and flows, generating a more efficient and intuitive work and admit an opportunity for improvements in terms of space and content management, and hence, cost savings for an organization. The combination of Lean tools was implemented, and the results have been checked, showing a significant impact in the hybrid warehouse, with annual gains through the optimization of several activities: employee turnover (decrease by 50%), check and picking times (decrease about 75 minutes/picking) and better working conditions for employees.info:eu-repo/semantics/publishedVersio

Dimensionamiento de Almacén a partir de la Planificación de Requerimiento de Materiales en una Fábrica de Revestimiento de Poliuretano

Context: the design of the warehouse is a key factor in the configuration of logistics systems, as it can facilitate the timely management of materials, intermediate and/or final products, improving the time, cost and levels of customer service. To achieve this, experts help is required to integrate within the design an appropriate combination of storage, manipulation of materials and selection of orders. This level of integration, however, has not yet been achieved since the advances in the subject have been addressed from different aspects of the storage problem, but independently.Method: the article presents a method for warehouse layout design in two phases. The first phase defines the variables and parameters that are obtained from the planning of the production; the second phase consists of five stages that culminate in the integral design of the warehouse. In this last phase a modified version of an existing mathematical model of sizing is applied, where a new equation is added.Results: the method is applied to a company that supplies liquid polyurethane in the construction sector. The design generates four options for configuration of shipping and receiving docks and five storage options, where the best option generates an average area, mean real capacity and percentage average of storage utilization of 374,8 m2, 360 pallet and 93,8% respectively. These results are coherent with the dynamics of the company.Conclusions: the method allows evaluating options of the flow configuration and their respective sizing than may influence decisions of great importance in the operational capacity of the company in the short, medium and long term. In the future research is interesting to include new conditions, for example the compatibility of the method with different distributions to the traditional configuration of parallel shelves. Contexto: el diseño del almacén es un factor clave en la configuración de los sistemas logísticos, pues facilita la gestión oportuna de materiales, productos intermedios o finales, mejorando el tiempo, costo y nivel de servicio al cliente. Para lograrlo se requiere el apoyo de expertos que integren en el diseño una combinación apropiada de almacenamiento, manipulación de materiales y selección de pedidos; sin embargo, tal nivel de integración aún no se ha logrado ya que los avances en el tema han sido abordados desde diferentes aspectos del dimensionamiento y de manera independiente.Método: se presenta un método de dimensionamiento de almacenes compuesto de dos fases. En la primera se definen variables y parámetros que son obtenidos a partir del proceso de planeación de la producción; en la segunda, se desarrollan cinco etapas que culminan con el diseño integral del almacén, en la cual se aplica un modelo matemático de dimensionamiento existente que incorpora una nueva ecuación.Resultados: el método de dimensionamiento de almacenes se aplica a una empresa que abastece poliuretano líquido en el sector de la construcción. Se generan cuatro opciones de configuración de muelles de recepción-envío y cinco opciones de almacenamiento; la mejor opción genera un área promedio, capacidad real promedio y porcentaje de utilización promedio de almacenamiento de 374,8 m2, 360 pallet y 93,8% respectivamente, siendo estos resultados acordes con la dinámica de la empresa.Conclusiones: el método es funcional en la organización, puesto que permite evaluar opciones de configuración de flujo y su respectivo dimensionamiento, los cuales pueden influir en decisiones de gran importancia, por ejemplo, en determinar la capacidad operativa de la empresa a corto, mediano y largo plazo. Igualmente, para futuras investigaciones es de interés estudiar nuevas condiciones como es la compatibilidad del método propuesto con distribuciones diferentes a la configuración tradicional de estanterías paralelas.
