Dynamické plánování expedice hotových výrbků metalurgického podniku

Abstract

The dissertation deals with industrial logistics. Specifically, it focuses on the issue of warehouse management in the metallurgical industry. In today's dynamic market environment with an ever-increasing degree of globalization, it is increasingly difficult for companies to remain competitive and meet the ever-increasing and changing requirements of the customer while maintaining an acceptable level of logistics costs. For manufacturing companies, logistics costs can represent up to 70% of the total costs. To remain competitive, companies need to make significant efforts to optimize logistics processes using automation and digitization tools. It is essential that companies manage all logistics activities systematically and comprehensively. The thesis was created in response to the results of previous studies in the field of logistics in the metallurgical industry, which showed that there is a great untapped potential in the metallurgical industry for optimizing warehousing and expedition processes. One of the basic shortcomings in the management of expedition warehouses in the metallurgical industry is the inefficient organization of product storage in expedition warehouses. Unsystematic storage of products causes waste and downtime during expeditions. The above led to the determination of the following objectives of the dissertation: • Analyze the current state of the expedition warehouse management system in a selected metallurgical plant. • Design a dynamic model of a decision support system for storing finished products in the expedition warehouse of a metallurgical plant • Design methodology for process analysis of logistics of expedition warehouses in a metallurgical plant. • Design methodology for creating a model of a system to support decision-making when storing products in the dispatch warehouse of a metallurgical company. To analyze the current state of knowledge of the issues addressed, part of the thesis is a search of literature. The result of the research is the definition of basic knowledge in the field of warehouse management, expedition, logistics, multicriteria decision-making, and process mapping. Important scientific publications dealing with similar problems are also analyzed. The practical part of the thesis is processed in the conditions of the expedition warehouse of the operation of the medium-fine rolling mill of the company LIBERTY STEEL Ostrava, a.s. First, a process analysis of the current state of management of warehousing and expedition processes in the examined warehouse is performed. Subsequently, a dynamic model of the system is created to support decision-making when storing finished products in the expedition warehouse, which will enable the achievement of the optimal use of warehouse space and a more efficient course of expedition processes. The proposed model is tested on selected warehouse events in defined warehouse conditions. The procedure and methods applied in the practical part are then used to create a general methodology for the dynamic management of the organization of the dispatch warehouse of a metallurgical company, which is applicable to all similar operations. The proposed methodology serves both for a thorough process analysis of the logistics of the expedition warehouse and the subsequent optimization of decision-making processes using a decision support system based on the application of the AHP method.
