Diploma thesis "The logistic chain of agricultural commodities" is focused on the analysis of material flow in agricultural sector. Work assesses the benefits of storing commodities after harvest or sale of produce without adjustment from field. The study evaluates the economic and process performance in terms of processing of agricultural commodities after harvest from the beginning to final option trading. The obtained data will be possible to assess benefits of storing commodities. In the practical part is analyzed profitability of investment i post-harvest lines and sets out proposal to stremline the logistics chain of commodities within the company DAŇHEL AGRO a.s.

The master's thesis focuses on distribution in a selected company. The company has been going through many changes which affect the whole logistic chain. The company is pushed by the current market situation to change processes in the central warehouse and in the costumer distribution. The author analyses all these changes and compares them to the theory. The author also proposes some improvements for efficiency increase in single parts of the logistic chain. There is not only theory used for these proposals. The proposed solutions are based on his own work experience and inspiration from different companies.

The aim of this thesis was to analyze the logistics to ensure the production and distribution of feed feedingstuffs, both in terms of material and information flow. I analyze these processes from initial purchases of raw materials for production, to distribution of finished products itself

The diploma thesis deals with the hospital logistics and current utilization of the logistic methods and principles by the regional hospital in Jičín. The aim of the thesis is to describe and analyse of current form of logistic system of the hospital and logistic processes in connection with the ensurance of material flows; to make the questionnaire; to identify the problems and to suggest solutions of optimalization of logistic processes and logistic chains that can lead to effective logistic system of the hospital.

Diploma work focuses on the application of logistics in a real manufacturing enterprise. Theoretical chapters define terms like logistics, logistic chain and describe individual segments in the logistic chain from developing, purchasing, manufacturing process to warehousing and distribution. Company Indoorcycling Group is introduced in the third chapter. The company deals with production of stationary bicycles and their accessories. After the characterization of the company, individual logistic processes are analyzed. According to detection of problems in the logistic chain, various solutions for the optimalization are suggested.

The aim of this thesis is the optimalization of chosen supplier chain from the point of view of material and informational flow, description of critical factors and a proposal for optimalization of the whole system from the point of view of logistic service and expenses. This thesis is devided into several parts. In the first part there are quoted some sources dealing with the topic of the thesis. In the second part present company functioning is described from the point of view of informational and material flow. These were analyzed within the conpany as well as between the company and the other parts of the chain. After evaluation of the results from the second part I tried to describe critical factors, which make the third part of the thesis. Ten critical factors were analyzed. The main part of the thesis is made by proposals for removing these critical factors.

The aim of the diploma thesis is to create a simulation model of the logistic chain of the inter-object transport of material, in order to verify the set requirements, which are require on the logistic chain. The simulation model is created in Plant Simulation software produced by Siemens PLM Software company. Section of this diploma thesis is the analysis of the solved area, the simulation experiments on the simulation model and suggestion for improvement the current state of the logistic chain.

La simulation est de plus en plus utilisée dans les études de conception et d’organisation des systèmes complexes. Une étude par optimisation via simulation permet d’optimiser les paramètres d’un système afin d’obtenir les meilleures performances, estimés par la simulation. Toutefois, dans de nombreux systèmes complexes, certaines données sont incertaines (par exemple, les conditions opératoires du système ou le comportement des décideurs). En conséquence, même lorsque l’étude d’optimisation via simulation est réalisée avec le plus grand soin, les solutions obtenues peuvent se révéler inadaptées. Dans ce contexte, notre objectif est d’étudier comment optimiser, via simulation, un système afin qu’il continue d’être performant et robuste. L’étude bibliographique approfondie que nous avons menée montre que très peu de travaux en optimisation via simulation intègrent l’incertain et qu’ils peuvent être très limités dans leur capacité à fournir des solutions robustes en un temps de calcul raisonnable en particulier lorsque des métaheuristiques sont employées. Par ailleurs, la plupart des travaux existants délivrent une solution unique de conception performante du système et ne sont pas adaptés pour prendre en compte les aspects collaboratifs (groupe de décideurs). C’est pourquoi, nous avons proposé une approche originale connectant une recherche des solutions par optimisation évolutionniste multimodale et une évaluation des performances du système via simulation. Notre approche va permettre de fournir plusieurs alternatives performantes de conception d’un système et assez diversifiées pour acquérir aux décideurs une flexibilité dans le choix de la solution à implanter. De plus, nous avons exploité cette flexibilité pour intégrer, d’une part, les préférences individuelles des membres d’une équipe décisionnelle et, d’autre part, la présence de plusieurs environnements pour étudier la robustesse des solutions en un temps de traitement raisonnable par rapport à d’autres approches utilisant des méta heuristiques. Les approches proposées sont illustrées par l’optimisation d’une maille de supply chain. Grâce à cette application, nous avons montré qu’en plus de fournir un choix de solutions performantes pour dimensionner le système, nous pouvons proposer des solutions « collectivement acceptable » pour l’équipe décisionnelle et déterminer des solutions de conception robustes du système. Ces approches fournissent ainsi une flexibilité pour la phase de décision et contribuent à la prise en compte de l’incertitude dans l’optimisation via simulation d’un système. / Simulation is more and more used in studies of design and organization of complex systems. A simulation optimization study search for the system parameters that yield the best performance. However, in many complex systems, data can be uncertain (e.g., the operating conditions of the system or the behavior of decision makers). Therefore, even when the simulation optimization study is performed with the greatest care, the solutions may be inadequate. In this context, our goal is to study how to optimize, via simulation, a robust system. The extensive literature review we conducted shows that few simulation optimization approaches incorporate uncertainty and they can be very limited in their ability to provide robust solutions in a reasonable processing time, especially when metaheuristics are used. In addition, most existing approaches provide a single solution to the design problem and are not adapted to take into account the collaborative aspects (decision maker’s team). Therefore, we propose a novel approach connecting a search for solutions by evolutionary multimodal optimization and the evaluation of the system performance by simulation. Our approach allows to obtain a diverse set of designs that can be considered as efficient in terms of their performance and to provide decision-Makers with flexibility in the choice of the solution to implement. In addition, we use this flexibility to integrate first, the individual preferences of the members of decision maker’s team and secondly, the presence of multiple environments For studying the robustness of solutions in a reasonable processing time compared to other approaches based on metaheuristics. The proposed approaches are illustrated with an example of supply chain. With this application, we have shown that in addition to providing a choice of efficient solutions for sizing the system, we propose "collectively acceptable" solutions to the decision-Making team and we identify robust solutions. Then, these approaches provide flexibility to the decision phase and contribute to the consideration of uncertainty in the simulation optimization of the system.
