OPTIMALIZATION OF LOGISTIC FLOWS IN THE ENTERPRISE
Dvořáček, Radim ; Linda, Bohdan (advisor)
The dissertation is concerned about, according to author still “live” problem of optimization of logistic flow, with scope to company environment. The aim is to find correct methodology for defined problem and to apply it to particular case study. Theoretical part begins with description and analysis of actual state of problematic of logistic flow optimization and listing the methods which are able to be applied to these problems. The three main groups – exact methods, heuristic methods and combined methods take part in. The analysis continues further with searching the methods, useful for application in production company environment. Vast focus is on layout design task, because once layout is created, except some minor changes, it lasts usually for some years and therefore it is necessary to consider it properly. Moreover, there is also difference between other characteristics of production, as production planning and machines / technologies upgrade and layout; the former are in a certain manner changeable and not stable, but the layout cannot be changed on for ex. weekly basis. Contribution to research is located at the end of theoretical part, which is newly modified methodology to be more suitable for practical application. Practical part begins with the description of particular case study, e.g. actual status of logistic system in enterprise. The processes described include purchasing management, production management and mainly layout design of production space. The application of suitable methods consists of group technology methods – already known method, plus newly modified method and their mutual comparison. In addition is included already known value stream mapping method. The result is recommendation for change in layout design, developed by integration of results, brought by group technology methods and value stream mapping method.

Solving the combinatorial optimization problems with the Ant Colony Optimization metaheuristic method
Chu, Andrej ; Jablonský, Josef (advisor) ; Janáček, Jaroslav (referee) ; Linda, Bohdan (referee)
The Ant Colony Optimization belongs into the metaheuristic methods category and it has been developing quite recently. So far it has shown its capabalities to over-perform other metaheuristic methods in quality of the solutions. This work brings analysis of the possible applications of the method on the classical optimization combinatorial problems -- traveling salesman problem, vehicle routing problem, knapsack problem, generalized assignment problem and maximal clique problem. It also deals with the practical experiments with application on several optimization problems and analysis of the time and memory complexity of such algorithms. The last part of the work is dedicated to the possibility of parallelization of the algorithm, which was result of the application of the ACO method on the traveling salesman problem. It brings analysis of the crucial operations and data synchronization issues, as well as practical example and demonstration of the parallelized version of the algorithm.
Environmental friendly behavior of company: Czech reality
Dvořák, Jiří Ing. ; Kovář, František (advisor) ; Hadrabová, Alena (referee) ; Linda, Bohdan (referee) ; Pokorný, Jan (referee)
Práce se zabývá otázkou vlivu managementu a ostatních stakeholderů na chování podnikatelské společnosti z hlediska jejího vlivu na životní prostředí. Současně je z tohoto pohledu porovnáno prostředí v České republice a v USA. Pomocí statistického vyhodnocení dotazníkových šetření byl osobní zájem managementu, a v menší míře i ostatních stakeholderů, o problematiku životního prostředí shledán klíčovým faktorem pro chování podnikatelské společnosti. Z tohoto pohledu nebyly zjištěny zásadní rozdíly mezi chováním společností z České republiky a z USA.
