This diploma thesis deals with the transport packages in Škoda Auto a.s.The aim of the thesis is to show the importance and problematic aspects of planning packages in the proces of logistics planning in the automotive industry. In the first part of the thesis are described the automotive industry as a whole, the packaging industry, its history, current trends, package types and functions, materials for their production and life cycle of the package. In the second part are introduced firm Skoda Auto, a.s.including its history, current information on the financial condition and produced quantity. There are described the types of transport containers and the process of their planning.On the example of the project CKD GAZ - Yeti is explained the development process of transport containers and then general management ot packages in circulation.

CAPES / O segmento downstream da cadeia de suprimentos da indústria brasileira de petróleo é composta por bases de produção (e.g. refinarias), armazenamento (e.g. terminais) e consumo (e.g. mercados consumidores) e modais de transportes (e.g. oleodutos, navios, caminhões e trens). O planejamento da transferência de derivados de petróleo nesta rede multimodal é um problema complexo e atualmente é realizado para um horizonte de três meses com base na experiência de profissionais e sem auxílio de um sistema computacional de apoio à decisão. Basicamente, o problema pode ser visto como uma negociação para alocação de recursos disponíveis (tais como derivados de petróleo, tanques e modais de transporte) pelas diferentes bases envolvidas que necessitam enviar ou receber derivados de petróleo. Na literatura, alguns problemas semelhantes, porém mais voltados para o planejamento de redes formadas por um único tipo de modal de transporte, têm sido tratados por diferentes abordagens, com predominância da programação matemática. Estes trabalhos ilustram a difícil tarefa de modelar grandes problemas por meio desta abordagem. Geralmente, tais trabalhos consideram apenas um curto horizonte de planejamento ou apenas uma parte do problema original, tal como uma parte da rede petrolífera brasileira, gerando limitações importantes para os modelos desenvolvidos. Devido às características do problema em estudo, o qual envolve toda a rede de transporte e apresenta perfil de negociação entre as diferentes entidades envolvidas, surge o interesse da utilização do paradigma de sistemas multiagente. O paradigma de agentes tem sido aplicado a problemas de diferentes contextos, particularmente em problemas de gerenciamento de cadeias de suprimentos devido à sua correspondência natural com a realidade e, em geral, em problemas que envolvem a competição por recursos por meio de mecanismos de negociação com base em leilões. Este trabalho apresenta um novo protocolo de negociação baseado em leilões e aplicação deste protocolo em forma de um modelo multiagente na resolução do problema de planejamento em questão. Os agentes que formam a solução representam principalmente os locais de produção, armazenamento, consumo e os modais de transporte na rede petrolífera brasileira. O objetivo destes agentes é manter um nível de estoque diário factível de cada produto em cada local por meio de transferências de produtos pela rede petrolífera brasileira com preferível redução do custo de transporte. Por fim, este trabalho apresenta a satisfação destes objetivos por meio de experimentos em cenários fictícios e reais da rede brasileira de petróleo. / The Brazilian oil supply chain is composed by oil refineries, consumer markets, terminals for intermediary storage and several transportation modals, such as pipelines, ships, trucks and trains. The transportation planning of oil products in this multimodal network is a complex problem that is currently performed manually based on expertise, for a period of three months, due to the lack of a software system to cover the problem complexity. Such problem involves the negotiation of available resources such as oil products, tanks and transportation modals between different sources and consumption points. Similar problems, but more directed to the planning of single modes of transportation, have been treated by different approaches, mainly mathematical programming. Such works illustrate the difficult task of modeling large problems with this mechanism. Generally, they consider a short horizon planning or only part of the original problem, such as a part of the network, rendering important limitations to the models developed. Due to the characteristics of the problem in study where the full network needs to be considered and there exists negotiation amongst the different entities involved, the usage of multi-agent models seems to be worth to explore. Such models have been applied in different contexts such as to supply chain problems due its natural correspondence with the reality. Furthermore, in problems involving competition for resources, multi-agents negotiation mechanisms based on auctions are commonly applied. Thus, this thesis presents one auction-based solution formed by the cooperation among agents for them to achieve their goals. The agents involved in the auctions represent mainly the production, storage and consumption locations. Their goal is to maintain a daily suitable inventory level for each product by means of transportation through the multimodal network at a low transport cost. Finally, this paper presents the satisfaction of these objectives through experiments on real and fictional scenarios of Brazilian oil network.

Approved for public release, distribution is unlimited / Commander, Logistics Group, Western Pacific (COMLOGWESTPAC) is concerned with the delivery of high priority material, ordnance, and passengers to U.S. Navy ships due to a very large operations area and limited Combat Logistics Force (CLF) assets. High-speed vessels (HSVs) may have the potential to improve the delivery of these materials when used to complement existing logistics shuttle ships. This thesis quantifies current levels of traditional naval logistics support and provides comparison to HSV-based alternatives in various scenarios. The CLF Scenario Analysis Tool (CLFSAT), a newly developed discrete event simulation model of naval logistics support, performs the analysis. Given a scenario depicting combatant movements and operations, CLFSAT provides insight into the comparative performance of different supporting naval logistics force structures. This analysis determines that HSVs can be effective logistics platforms in specific scenarios when distributing high priority material, ordnance, and stores. HSVs are very effective in small theaters with short transit distances, but for larger theaters, their effectiveness is inversely proportional to distance from the Forward Logistics Site. Regardless of theater size, HSVs show significant improvements in theater distribution of "low density, high priority" cargo, such as precision guided munitions (PGMs) or critical repair parts when customers are outside COD range. / Lieutenant Commander, United States Navy

Approved for public release, distribution is unlimited / The Navy has to choose the number of, and designs for, ships in the Combat Logistics Force (CLF), and then plan how to use them to provide logistical support to our Carrier Strike Groups, Expeditionary Strike Groups, and Seabasing platforms engaged in any variety of worldwide conflicts. CLF ships are very expensive to build and equip and our budget is limited --- we need to make sure the ships we buy and the way we integrate these with our CLF fleet can continue to provide the flexible support our Navy requires. We introduce a decision support tool using a global sea route and resupply base model, and a daily time resolution optimization of CLF ship activities to support any complete, worldwide scenario. Our result is an optimal, face-valid daily operational logistics plan - a schedule of evolutions for each available CLF ship. We discover exactly how to use CLF ships to support a notional, but particularly relevant, preemptive combat scenario with follow-on humanitarian assistance missions. Finally, we study how changing CLF ship numbers and missions can enhance operational effectiveness. / Lieutenant Commander, United States Navy
