Warehouse management is becoming an increasingly important task and responsibility for employers whose goal is to maximize the profitability of the whole business. In this paper, a comparative ...analysis of warehouse processes was made on selected case studies of three companies by the methodology that is divided into several phases: the current state of the warehouse system was analyzed, proposal for optimization according to detected bottlenecks was made, and finally the success control of the introduced optimization proposals. The purpose of the comparative analysis is to show differences and similarities in bottlenecks and process times between warehouses. The paper's goals: the identification and optimization of critical factors that affect the warehouse processes' execution quality and speed in practice, and to prove that by combining simple methods and tools without complex algorithms, a significant level of warehouse processes optimization can be achieved, thus increasing efficiency. Limitations of research are: the research is conducted in only three warehouses, the warehouses store similar types of goods, while the different warehouse types inclusion would certainly give a more detailed overview of the factors; the research was not conducted at the same time in warehouses, but iteratively over a year, the problem of seasonality may also affect the collected data; and there is a possibility of subjectivity during the field measurement because it was divided among the members of the measurement team. During the field measurement and data analysis, factors that lengthen the duration of the process were observed so for the purpose of business improvement certain optimization proposals are given.
The basis of each IT system is data exchange both between individual modules of program and between program and user. The number of exchanged data and the number of operations on the data, which ...should be performed, require application of professional tools allowing for collecting and performing operations on multiple types of data. One of these tools are databases, which are an essential part of any IT system. With database designing are connected many decision problems which can occur both during the construction of database management system and at the stage of integration of entire user application with developed database. The article presents typical decision problems connected with designing of databases. These problems mainly concern sphere of information technology (including the programming language or recovery mechanism of database after the failure). Database architecture for typical IT system from the point of view possible paths for users were discussed, and role of catalogues played in development of database were presented. In addition, modular structure of the database, which was developed for the system SIMMAG3D for modelling and visualization of warehouse facilities in 3D was shown. This system is being developed under a project financed by the National Centre for Research and Development. We discussed in detail one of the essential elements in developed database - catalogues of means of external and internal transport, non-mechanical equipment and accessories which are essential from the point of view of the work load.
This paper presents an overview of integrating warehouse design and optimization modelling approach to enhance the supply chain performance. The approach is derived through a literature review as ...well as by considering the practitioners approach in the Sri Lankan context. The method is explained along with the framework to integrate the isolated solutions and derive the overall warehouse design solution, simulation, and optimization models. The main contribution of this paper is to guide the practitioners in consistently maintaining an optimum warehouse operation through warehouse design to enhance supply chain performance.
Warehouses see an increased need to become more and more digitalized and automated. This paper will look at a 3PL company operating warehouses worldwide with all types of customers. With the ...increased need for warehouse space, it becomes essential to standardize and automate warehouse operations. This paper will present several initiatives to standardize and digitalize warehouses to prepare them for automation. The four standardization initiatives that are investigated and presented for the case company are: Streamlined process flows based on offered services, automated put-away, automated setup of new clients based on predefined options with a configurator, and an automation framework to standardize the requirements for implementation of automation. Each initiative was developed and presented to different stakeholders at the warehouses. The stakeholders showed interest in the initiatives and especially the streamlined process flows, and the configurator will be implemented. It became clear that the biggest challenge will be implementing the suggested solutions on a big scale in multiple warehouses. However, this is also where the most significant benefits are as the benefits of running multiple warehouses can be archived.
In general, most warehouse managers lack timely and quality information derived from traditional warehouse management systems. This paper proposes a design of intelligent warehouse capable of ...tracking good's static and dynamic data in a real-time basis. The system merges different ICTs such as RFID and WSNs to manage and monitor six warehouse intelligent processes, which are stock-in/stock-out, put-away, stocktaking, product's localization, forklift's localization and pre-shipment control. We have proposed different technology implementations to accurately respond to the six processes' requirements. We provide a technology framework that covers all warehouse operations. Moreover, we give more attention to the stocktaking process to fill the gap of the literature. To this extant, we propose the most suitable implementation of integrated RFID and WSN so as to increase RFID reading range in order to cover the whole stock area. The integrated solution not only accomplish stocktaking easily and accurately, but also helps on locating miss-placed products and monitors the ambient temperature of the warehouse. The system is accurate and cost effective.

Paper presents problems of designing and organization logistic processes in warehouse facilities. Highlighted the need of improving logistics facilities actions as a key aspect of increasing ...productivity, flexibility and reliability of supply chains. For this purpose, warehouse process and the most common sub-processes and activities included in it were characterized. Additionally, it was noted that, warehouse processes may be implemented in many different ways and under various strategies. Selection of particular warehouse strategy usually depends on basic warehouse tasks, structure and size of customer orders, handled logistic units, costs of materials handling in particular sub-processes (both financial and time costs), availability of storage space and labour resources, etc. Therefore, probability of selecting the particular strategy is dependent on technical and organizational factors. Because of that, the paper presents some approach to selecting warehousing strategy. This approach takes into account mentioned technical and organizational factors. It also uses decision-making tree which shows probabilities of selection subsequent warehouse operations (in particular moment and warehouse situation) as well as probability of such situations as e.g. shipment suspending or cancelation in case of choosing a given strategy. Examples of such decision-making tree with probabilities of warehouse strategy selection is shown in paper.
The objective of warehouse processes is to satisfy customer's desires and requirements whilst using house, equipment and labour effectively. However, in Nigeria studies have revealed operational ...problems in warehousing and a lack of customer satisfaction in the delivery of construction materials. The aim of this study was to evaluate the level of customer satisfaction with the delivery of construction material from the manufacturers' warehouses to customers or other terminals, with a view to improving the operations. This article adopted a case study research design method in which quantitative data were collected and analysed. The target population was the North-Central geo-political zone of Nigeria. A total of 32 construction material manufacturers were purposively selected from the zone. The observation and measurement approaches were adopted for data collection. A total of 72 customers' orders were observed and recorded to be representative of deliveries from the sampled (n = 32) manufacturers' warehouses to other terminals. A customer quintile benchmark metric was also adopted for analysis and for comparing field results with best practices. The findings revealed that the involved construction material manufacturers' warehouse processes, were suboptimal and ineffective in terms of perfect order completion and total order cycle time. These results indicated major opportunities for improvement. This article concludes with providing construction material manufacturers with information about their warehouse processes that might help to ensure that the construction material arrives at its final destination in optimal quality, time and cost.
This research paper deals with the implementation of modern barcode systems supported by mobile technology. As much as barcoding, has grown to have many applications in retail trade and stores ...selling consumer goods, there is still space for improvement of business processes in specific business systems. If implemented in the large production systems as a support to ERP systems, it can make a difference in the business processes, especially in terms of improving sales processes through improvement of warehouse processes. Timely and updated information on the current state of stocks or shipping schedule are prerequisite to competitiveness in the global trade. We investigated the problems, solutions and benefits of improvement of warehouse processes by implementing mobile barcode systems in a medium-sized wholesaler and a large enterprise engaged in metal manufacturing industry with a specific small-scale production.
