Analysis of material flow in the loading system production using computer simulation
Loprais, Pavel ; Kašpárek, Jaroslav (referee) ; Urbánek, Michal (advisor)
Bachelor thesis focuses on the elaboration of a literary review of computer software used for modelling and simulating material flow in manufacturing. According to the proposed layout concept, a computer simulation model of loading circuits will be created, including the configuration of basic operational parameters using the Plant Simulation program. The work involves a detailed description of information flows in the loading line, including the implementation of proposed systems into the computer model. An analysis will be conducted to assess the impact of simulation model parameters on the discussed characteristics of material and information flows.

Heuristic algorithm for freight transport logistics
Hobža, Jakub ; Nevrlý, Vlastimír (referee) ; Kůdela, Jakub (advisor)
This thesis deals with the solution of a real-world optimisation problem of DS Logistics, s.r.o., where the objective is to minimise the transportation costs given by the distance travelled. At the same time, a number of company-specific requirements have to be fulfilled. The work focuses on the use of heuristic and metaheuristic algorithms, and four different solution methods are presented. At the end of the thesis, these methods are compared on several instances. The best results were obtained using simulated annealing.

Analysis of material flow in a production line using computer simulation
Karas, Lukáš ; Kašpárek, Jaroslav (referee) ; Urbánek, Michal (advisor)
This bachelor ‘s thesis deals with the creation of a material flow analysis of the production system. The first part of the thesis is focused on the literature search of logistics and computer simulation software. The second part deals with the creation of the layout of the production system and the creation of a simulation model. Simulations are performed using the Technomatix Plant Simulation software developed by Siemens company. In the third part, an analysis of the results of the matrix of simulation experiments is carried out. At the end of the work, an evaluation of the results of the performed analyzes is carried out.

The Reverse Logistics in the Selected Company
Šándorová, Hana ; Mráček, Pavel (referee) ; Milichovský, František (advisor)
In my bachelor's thesis, I focused on the issue of reverse logistics at a selected branch of the company, which dominates the market in the respective segment. I examined various departments in terms of their logistics processes and based on analyses and research, I proposed measures to streamline reverse logistics and minimize waste generated in the Food. The work focuses on a detailed description of the company's branch and an analysis of the current state of logistics processes in certain departments. The analyses are based on data obtained from these workplaces and my professional experience in the company. In addition, I conducted research through my own observations. Based on these analyses and research, I developed a set of measures aimed at improving the efficiency of reverse logistics, minimizing the negative impact of the company's activities on the environment, and increasing customer satisfaction in the Food department.

Application of Mathematical and Statistical Methods in Company Management
Zezula, Lukáš ; Šustrová, Tereza (referee) ; Novotná, Veronika (advisor)
This thesis discusses the analysis of logistics costs for a company operating a network of vending machines and the subsequent minimization of the established costs by changing the locations and number of supply depots. A function reflecting the dependence of transport, warehousing, and inventory holding costs on the number and locations of depots is derived. The coefficients of this objective function are identified based on data provided by the analyzed company. Optimization of the locations and number of supply depots is performed using the Nelder and Mead iterative algorithm in combination with agglomerative clustering. The proposed approach to optimizing the logistics network is described from a mathematical-statistical and implementation perspective. Special attention is paid to finding optimal routes between supply depots and vending machines using geographic software, which also allows for measuring the route length and the time required to cover the obtained distance. The thesis then presents six proposals for reorganizing the logistics network, reflecting the optimal distribution of supply depots at their different numbers. Various shapes of the inventory holding costs are also considered, and their impact on the optimal number and locations of supply depots is discussed.

Optimization of Logistics System in Selected Company
RYCHNOVSKÁ, Magda
This work examines whether the logistic technologies and methods currently in use are suitable and sufficient for the future development of OPTOKON, a medium-sized company specializing in fiber optic technologies. The work presents the results of direct process observation, guided employee interviews, and data processing from the operational records of the information system. The most significant advantage lies in the implementation of the Just-in-Time logistic method, coupled with the use of barcodes and QR codes for marking, scanning, and tracking the movement of all materials and products within the company. This new marking system has a positive impact on the quality of products and services, and, most importantly, it enhances customer satisfaction by expediting and streamlining processes. The analysis and positive feedback from customers resulting from these changes will enable the company to make any necessary adjustments to its business activities, ensuring the company's sustainability and continued profitability.

Characteristics and application of logistics processes in the company
DOHNALOVÁ, Lucie
This thesis deals with the characteristics of logistics and its application in a selected company. The main objective of this thesis is to characterize logistics activities and to evaluate them on the basis of a set of indicators. The data was collected using several methods, including direct observation, direct participation in operations, data analysis, ABC method and guided interview with selected company personnel. The main task is to elaborate and analyse the logistics activities and define a set of indicators on the basis of which the evaluation of these activities is carried out. The defined indicators include supplier ratings, frequency of goods orders, delivery time, volume of returned goods, stock utilization, volume of stocked goods, delivery time to customers, complaints, % of customer satisfaction. Based on the findings, measures to improve the current process are proposed at the end of this thesis, which relate to the identification of inventory and saving staff time. As part of the proposal, it was also recommended to monitor new indicators such as quality of service and order fulfilment rate.

Using Industry 4.0 principles for mobile warehouse design
Eisenwort, Lukáš ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
The aim of this diploma thesis is to apply industry 4.0 principles for designing a mo-bile warehouse. The first section contains the literary research, which deals with industry 4.0 in logistics. Next part deals smart warehouses and military warehouses. Analysis of the current state of the warehouse follows, technologies and processes in the military warehouse to be exact. Afterwards, the automation design of this warehouse is addressed. Both the current and the automated states are compared using the Saaty method. Finally, the photovoltaic system is designed.
