The aim of the research is to develop an effective package addressing scheme and to introduce a special code that will enable precise management of profile storage and will improve the process of completing customer orders. Design/methodology/approach: The simulation project management methodology is based on several key steps: defining goals and requirements, collecting data and modeling, designing scenarios, performing simulations, and designing an individual addressing scheme for parcels in the warehouse. Findings: Simulations allow you to find the optimal warehouse layout that ensures effective use of the available space. This, in turn, allows you to increase the storage capacity and better organize the storage of profiles, which translates into minimizing losses and costs. Simulations allow you to test different strategies for placing profiles in a warehouse to minimize the time and effort needed to find them. Optimizing the placement process allows parcels to be located faster and more precisely, which speeds up order picking. Research limitations/implications: Simulation-based process optimization requires model accuracy and reliability. Imprecise or inaccurate data can affect simulation results and lead to inappropriate decisions. This requires careful data collection and model validation before implementation. Further research may focus on optimizing routes inside the warehouse and optimizing internal logistics. Investigating the best routes and methods of transport will minimize the time your products pass through your warehouse. Research can introduce an element of random events, such as machine breakdowns or fluctuating demand, into the simulation model to better reflect real conditions and increase the reliability of the results. Practical implications: Improvement of warehouse processes and the introduction of a special code addressing the shipment can significantly reduce the risk of errors and material losses, which contributes to greater accuracy and efficiency of operation and improvement of customer relations. R. Poloczek, B. Oleksiak Social implications: Effective optimization of warehouse and production processes contributes to increased work efficiency. Reduction of redundant activities, more precise management of resources, and more efficient order picking can affect employee satisfaction as well as positively affect working conditions and security. Originality/value: The key element of originality is using advanced FlexSim software for modeling and simulation of storage processes and producing galvanized steel profiles. Simulations of this type integrated with real data and the implementation of a special package addressing code constitute a comprehensive approach to optimizing the entire process. The results of such a study can have a significant impact on the practice in manufacturing companies, enabling more effective warehouse management, shortening the time of picking orders, reducing costs, optimal use of resources, and improving the quality of customer service. It is an interdisciplinary approach that combines aspects of production management, logistics, process optimization, and the use of advanced IT tools.

According to the microeconomic approach, distribution is more identified with the sales and delivery process, and the main tasks of the distribution centre include the storage of goods owned by suppliers and distributing them to recipients according to the specific instructions of the goods' owner. This article presents costs reduction and productivity improvement issues in warehouses and distribution centres. The objective of this article is to define order picking problems and to choose the best route for the operator using real simulation and optimisation.

This share mainly covers the area of fasteners, such as nuts, screws, bolts, buckles and springs. The unquestionable advantages of flake coatings include, among others, high corrosion resistance, total absence of chromium (VI) and hydrogenation of the parts, as well as good resistance to chemicals or UV resistance. This paper presents application methods and selected properties of zinc flake coatings.

Increasing competition resulting from the use of production automation to increase productivity has increased the complexity of production systems that can only be analysed by simulation. Production logistics performs management functions such as planning, motivating, organising and controlling. It does not deal with technological processes, but the organisation of physical delivery and displacement of components and information in the system. An important feature of production logistics is combining supply logistics with distribution logistics. If the production logistics is properly organised, it provides access to all materials and components of a given product during the implementation of a specific order. Simulation tools ensure continuity and rhythm of production after it is started, as well as con...

Typically, the amount of purchased assortment is so large that it can be stated that the share of materials in the total costs of the company is significant. The indicator of a modern enterprise is the number of clients and their level of satisfaction, which is why quality is a key factor for each production company (Kuczyńska-Chałada, and Furman, 2016) and an important element of process improvement is also an aspect of work safety (Małysa et al., 2019). The purpose of this article is to show that the process of choosing a reliable supplier does not end with choosing the supplier that offers the lowest rates for materials, but other elements that should be considered when choosing a supplier. Design/methodology/approach: This is a research paper and the author presents the process of suppliers' qualification using the specified supplier evaluation criteria. Findings: Before writing the paper we put a hypothesis stating an important feature of the supplier should be flexibility and readiness to change, develop and implement new solutions, because the supplier should strive for the customer. Research limitations/implications: This is a research paper and the author utilized survey method. Practical implications: What criteria determine the selection of the best supplier for the enterprise.

One of the principal and at the same time necessary conditions to achieve this aim is continuous development of all of the processes in order to fulfil various clients’ expectations. Enterprises make use of different concepts and management methods which in significant way upgrade ongoing processes by raising their efficiency. One of such is the concept of ‘lean’ production - Lean Manufacturing. Management according to Lean Management rules allows to produce more with the use of less resources - at the same time approaching the aim which is to deliver clients the exact product they want. The process of resources use limitation is not easy to perform however, the concept of Lean Manufacturing by the application of chosen tools allows successfully and effectively to introduce ‘lean’ model of managem...

This requires the observation of new conditions for logistics as well as its multifaceted analysis, i.e. the perception of mutual relations and impact. New logistics concepts resulting from technological development will be created. One of the new solutions is the concept of Industry 4.0, the implementation of which can generate innovative solutions and long-term effects on the industry, including significantly production logistics.
