Input data for municipal waste collection routes optimization
Kulich, Marek ; Nevrlý, Vlastimír (referee) ; Pavlas, Martin (advisor)
The aim of the thesis is to describe the systems of collection of separated waste as well as collection monitoring, which includes identification of containers, sensors and data transfer. The data is then summarized and analyzed for use in the optimization software that uses advanced ARP models. The practical part is devoted to the analysis of real data sets. On selected geographical area are determined the parameters of waste, the plan of the collection routes and their evaluation. The use of local infrastructure will be then shown by cartographic representations of the routes in the maps.

Transportation systems in waste management
Koutná, Marie ; Pavlas, Martin (referee) ; Gregor, Jiří (advisor)
The aim of the thesis is to elaborate on transport systems in waste management as they represent a key part of the waste management process. Its theoretical part covers legislation in waste management and sorts and systems of household waste collection. In the practical part there are commercially used vehicles chosen out and the fixed costs of their operation determined. Based on operation data, average velocities in an out of urban areas are calculated. As an outcome of a waste transport prices software, the influence of transport distance and waste mass are described, taking the average velocities into account.

Emerging systems of collection in waste management
Petrasová, Zuzana ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
The main aim of the thesis is a description of the methods used in the collection of waste with a focus on non-traditional ways. Its part is the outline of a basic technical specification of the methods. The analysis is further used to determine the technical-economic model for underground waste containers, which is able to calculate the construction costs based on given values. The model is designed for containers of three different volumes and is the main result of the thesis. The knowledge of input investments is being used to compare the economic demand and the potential return of investments with regards to the traditional collecting methods (bins, containers) and the pneumatic underground system, whose estimated costs are taken from foreign models.

Simulation model of waste collection for Network Simulator 3
Kolaja, Lukáš ; Mlýnek, Petr (referee) ; Fujdiak, Radek (advisor)
The goal of this diploma thesis is create an application for route optimalization for waste collection which is one of the technologies of smart cities. At first was described issue of smart cities focused to waste collection. The thesis describes the real deployment of smart waste collection using sensor network and was also designed its own model of smart waste collection. It is also described graph theory and related genetic algorithms which is suitable for waste collection optimalization. On that basics an application was made in C/C++ language which using a genetic algorithm to compute best possible path in graph which represents a map where waste is collected. By input data to application is vector image of evaluated graph in SVG data format.

Recycling plants in the Czech Republic
Průžková, Kateřina ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
This bachelor thesis is focused on recycling the municipal waste components (glass, paper, plastic). First part of the thesis contains a research into the current state of the waste management and its collection technologies. The following chapter consists in description of the waste components, their recycling and utilization as secondary raw materials including resource efficiency during the plastic recycling. The next part of the work comprises the list of recycling plants, which is sorted by the type of the waste processed. A separate chapter is focused on the technology of the plastic processing recycling line and its energy intensity. Subsequently, the cost of this recycling line and its components is introduced.

Analysis of traffic data related to risks in waste management
Vaníček, Filip ; Smejkalová, Veronika (referee) ; Popela, Pavel (advisor)
The aim of this thesis is to prepare real data for subsequent optimization of the collection plan using advanced VRP („Vehicle Routing Problem “) algorithms. The diploma thesis is motivated by the project Strategic Partnership for Environmental Technologies and Energy Production. The output focuses on indeterminate factors that have a major risk for subsequent operations. These are economic, environmental and social risks (overcrowded containers). Another result is the implementation and processing of the time-consuming passage of all streets, the estimation of the speed of the collection (garbage) truck for the subsequent optimization of the route and the estimation of the mean value of the filling of individual collection containers.

Web application for waste containers placement planning
Vidlička, Adam ; Roupec, Jan (referee) ; Dobrovský, Ladislav (advisor)
The aim of this master's thesis is to create a web application that will serve as a tool for creation and management of municipal waste collection infrastructure. Computational functions developed at the Institute of Process Engineering will be utilized for more optimal creation of the waste collection infrastructure. The theoretical part of the thesis deals with the zoom in on waste management in the Czech Republic, the motivation behind developing the web application, and the technologies used during its development. The practical part of the thesis describes the creation of the basic concept of the web application and provides subsequent descriptions of its individual components.

Operational Research in Waste Management: Task Reduction Techniques
Janošťák, František ; Máša, Vítězslav (referee) ; Šenkeřík, Roman (referee) ; Pavlas, Martin (advisor)
The dissertation thesis focuses on reducing the computational complexity of selected modeling tasks in waste management. Two types of optimization tasks are presented here. First, attention is focuses on transport tasks. Current computational tools approach transport tasks with greatly simplified models of transportation costs. The thesis presents a more accurate model of transportation costs and describes its implementation into the long-term successfully used unique tool NERUDA. The improved tool provides more accurate results, however, requires more computational time. The work describes cases where the original tool provides results comparable to the improved one and suggests the methodology of how to identify, even before the calculation, whether the use of optimized models is necessary. The work continues in the area of scenario approaches, which output a significant amount of transport task results. Analysis of the results and their processing is key for further use in practice. The currently used tool works with future development scenarios where one result is calculated for each scenario. In many cases, the results are very similar, but their quantity hinders the following analysis The thesis describes an approach based on cluster analysis, which groups the results into categories and thereby significantly aids their processing and interpretation. The second type of tasks is represented by the optimization of the conceptual design of a waste-to-energy plant and a heating plant cooperation. In general, this is a stochastic mixed integer non-linear programming problem. The work presents an innovative approach, which, based on the decomposition of the task and its parallel solution, allows working with higher accuracy without a significant increase in computing time.

Web application for planning waste fractions collection
Kubowský, Jiří ; Šeda, Miloš (referee) ; Dobrovský, Ladislav (advisor)
The aim of this thesis is to develop a web application to support the planning of waste collection with an emphasis on a user-friendly interface and variability in terms of configurability of task boundary conditions. The development of the application builds on models and algorithms developed in the field of waste management. The application will be a tool for end users to work with these data, models, and algorithms. In the theoretical part, the issues of waste sorting and collection are presented. The practical part deals with the development of the web application from the basic concept, through the technologies used, to the details of the actual implementation.
