How can a Mobile Hub enable Circular Flow in Urban Logistics?

Piplai, Shirshendu January 2021 (has links)
With the world’s population moving to urban areas due to an increase in population and employment opportunities, e-commerce businesses need to drastically improve logistics to levelwith the eruptive demand from the customers. This expands an already major need to undertake a study on urban logistics management to highlight its best practices. The most sustainable means of “End mile delivery” is a cargo bike, but this operation is limited to selective areas of the city. This prompts van deliveries to be an integral part of logistics, even for small packages. Major limitations of the cargo bike operation not expanding is the non-consolidation of package and routing issues. This research holistically explores how simulation techniques, such as “Agent-Based Modeling”, can play a vital role in the operational side of logistics management and planning. These models can solve the issues, such as package sorting, for cargo bike riders which are facilitated by a mobile hub. This smart mobile hub operation collaborates with the cargo bikes to ensure a larger geo-fence and higher vehicle utilization. Further study of reverse logistic policies in Stockholm is incorporated in the model, to establish a circular economy. An “ABM”, simulating the daily operation of this new proposed urban logistics, has been developed on AnyLogic®. / I takt med världsbefolkningens förflyttning till städer behöver e-handelsindustrin drastiskt förbättra logistiken för att möta den ständigt ökande efterfrågan hos konsumenter. Detta utvidgar ett redan stort behov av studier av stadslogistikhantering för att lyfta fram dess bästa praktiker. Det mest hållbara medlet för ”End mile delivery” är lastcyklar, men de är begränsade till utvalda stadsområden. Således blir skåpbilsleveranser en väsentlig del av logistiken, även gällande mindre paket. Brist på utveckling av lastcyklarnas stora begränsningar är paket- och ruttproblemens icke-konsolidering. Denna forskning utforskar holistiskt hur simulationstekniker, såsom ”Agent-Baserad modellering”, kan spela en väsentlig roll i den operativa sidan av logistik-hantering och planering. Dessa modeller kan lösa lastcyklarnas problem, däribland med paketsorteringen, vilka underlättas med hjälp av ett mobilt nav. Denna smarta mobila-nav-verksamhet samarbetar med lastcyklarna för att säkra ett större geo-fence och högre fordonsutnyttjande. Vidare studie av returlogistik-regelverk i Stockholm är inkorporerad i modellen, för att etablera en cirkulärekonomi. En ”ABM”, som simulerar den dagliga driften av denna nya föreslagna stadslogistik, har blivit utvecklad på AnyLogic®.

Based on this premise, this study sought to point out the economic potential and the challenges encountered in the new air terminal in Goiânia, Goiás state, opened in the year 2016. In addition, addressed the relationship between logistics and the means of transport, particularly air transport, the importance of airport infrastructure efficiently to the dynamics of the market, as well as the relationship between the airport of Goiânia and regional development. It was verified that: even with the inauguration of the new terminal, there was no significant increase in the volume of cargo transported; the base of the economy in Goiás depends fundamentally on the road and rail modes, with the exception of pharmaceutical and automotive industries, which use the air service; and the proximity to Brasília hinders investment and development in the sector, as it is not economically viable to two poles nearby. / Analisar meios de transporte é fundamental para a compreensão acerca da formação dos grandes centros urbanos e o desenvolvimento econômico local, regional e nacional. Com base nessa premissa, o presente estudo buscou apontar as potencialidades econômicas e os desafios encontrados no novo terminal aéreo de Goiânia, estado de Goiás, inaugurado no ano de 2016. Diante disso, abordou-se a relação entre a logística e os meios de transporte, em especial o aéreo, a importância de uma infraestrutura aeroportuária eficiente para a dinâmica de mercado, bem como a relação entre o aeroporto de Goiânia e o desenvolvimento regional. Constatou-se que: mesmo com a inauguração do novo terminal, não houve aumento significativo no volume de cargas transportadas; a base da economia em Goiás depende fundamentalmente dos modais rodoviário e ferroviário, com exceção das indústrias farmacêutica e automobilística, que utilizam o serviço aéreo; e a proximidade com Brasília dificulta investimentos e desenvolvimento no setor, visto não ser economicamente viável dois polos próximos

Analýza vývojových trendů v řízení silničních nákladních flotil / Development trends analysis in fleet management

MILISDÖRFEROVÁ, Pavla January 2007 (has links)
I have dealt with fleet management analysis in my thesis. The base of this analysis is monitoring development trends in this area. Development trends are especially mobile phones, software equipment, satellite systems, digital tachographs, fulfilment conditions of emission standards EURO 4 and EURO 5 (technologies EGR and SCR), quality and environment management and last but not least problems in fuel consumption management.
