The logistics industry causes various harms to the environment. The literature assigns the main responsibility for alleviating such harms to two supply chain actors: shippers (logistics buyers) and logistics service providers (LSPs), which motivated studying them in this thesis. Specifically, this thesis explores and identifies how green logistics practices can be facilitated through aligning both actors throughout the different phases of their relationships. Two studies are compiled. The first study is based on five distinct cases -- three shippers and five LSPs, providing the basis for two papers: (i) one that analyses the institutional pressures (regulatory, market, competitive) on shippers to purchase green logistics services, and on LSPs to provide these services, and (ii) one that investigates the two actors’ stances on environmental concerns in the four key logistics purchasing phases (request for proposal, negotiations, contracting, execution), while proposing ways to align their efforts along such phases. The second study covers a single case of a dyadic relationship between a shipper and its LSP, handling enhancing logistics performance (cost efficiency, on-time delivery) in the early stages of their relationship. The findings indicate a general lack of regulatory pressure in driving shippers and LSPs to engage in green logistics, contrasted by a long-term influence of competitive pressure and a prevalent influence of market pressure. It was also found that both actors must put substantial efforts in the beginning of their relationships to reach a mutual business understanding, allowing performance and green enhancements. In the execution, it was found that both partners should regularly communicate performance metrics while modifying working standards, which would also support their green practices. For practitioners, insights are offered to align shippers’ and LSPs’ efforts within their relationships to attain positive performance and green outcomes. / <p>QC 20180223</p>

Thesis (MPhil) -- Stellenbosch University, 2000. / ENGLISH ABSTRACT: This study is aimed at determining whether the Port of Walvis Bay has what it takes to become a future hub port on the south-western coast of Africa. An equally important aspect of this study is to promote Walvis Bay as an economically viable option for trade in and out of Central and Southern Africa, and what proportion of traffic Walvis Bay could expect to capture from competing regional ports, especially the ports of Durban and Cape Town. The conclusions arrived at in this study indicate that the prospects for transforming Walvis Bay into a future hub port will depend on the increased involvement of the private sector, political and industrial stability, as well as regional integration to mention just a few. It is clear that Walvis Bay does not pose a competitive threat to the ports of Cape Town and Durban, and can only perform a complementary role. / AFRIKAANSE OPSOMMING: Die doel van hierdie studiestuk is om te bepaal of die Hawe van Walvisbaai oor die vermoë beskik om ‘n sentrale hawe vir die suidelike en weskus van Afrika te wees. ‘n Belangrike aspek van die studie is om Walvisbaai te bevorder as ‘n ekonomiese alternatief vir handel na en vanaf Sentraal en Suidelike Afrika, en om die verhouding van verkeer te bepaal wat gewen kan word vanaf kompeterende hawens in die streek, veral die Durbanse en Kaapse Hawens. Die resultate bewys dat die moontlikhede om Walvisbaai te omskep in ‘n toekomstige sentrale hawe, alleenlik deur die deelname en samewerking van die privaatsektor, politieke goeie wil, die industriële stabiliteit van die land en integrasie met buurstate bewerkstellig kan word. Walvisbaai hou geen kompeterende bedreiging in vir die hawens van Kaapstad en Durban nie, en kan slegs ‘n komplementerende rol speel.

Thesis (MEcon)--Stellenbosch University, 1997. / ENGLISH ABSTRACT: On 31 March 1990 the South African Transport Services (SATS) ceased to exist and on 1 April 1990 in its place emerged Transnet, a diversified transport company wholly owned by the South African government. Transnet was founded on the understanding that the government might eventually choose to sell it to the private sector. This study project report discusses the history and events leading up to the creation of Transnet. Thereafter the advantages and disadvantages of privatisation are identified, followed by international privatisation case studies which provide the basis for a discussion of some of the economic issues behind railway privatisation. The separation of infrastructure from operations, which was identified through the case studies as one of the most controversial and far-reaching concepts of railway privatisation, is also examined. Lastly, the study project focuses on the marketing strategy Spoornet ought to pursue in order to ensure sufficient high-value freight in the future. / AFRIKAANSE OPSOMMING: Op 31 Maart 1990 het die Suid-Afrikaanse Vervoerdienste ophou bestaan en is dit op 1 April 1990 vervang deur Transnet, 'n gediversifiseerde vervoermaatskappy wat deur die Suid-Afrikaanse regering besit word. Van meet afwas dit die bedoeling dat die regering die keuse het om Transnet aan die privaatsektor te verkoop. Die werkstuk bespreek die geskiedenis en gebeure wat aanleiding gegee het tot die ontstaan van Transnet. Daarna word die voor- en nadele van privatisering bespreek, gevolg deur internasionale spoorwegprivateriseringsgevallestudies. Daarna word die ekonomiese teorie wat privatisering onderle, bespreek. Die skeiding van infrastruktuur en bedryf, wat deur die gevallestudies as een van die mees omstrede en verreikende aspekte van spoorwegprivatisering ge"identifiseer is, word ook bespreek. Laastens fokus die werkstuk op die bemarkingstrategie wat Spoornet behoort na te streef om hoe-waarde vragte te bekom.

Due to restricted budgets of relief organizations, costs of hiring transportation service providers steer distribution decisions and limit the impact of disaster relief. To improve the success of future humanitarian operations, it is of paramount importance to understand this relationship in detail and to identify mitigation actions, always considering the interdependencies between multiple independent actors in humanitarian logistics. In this paper, we develop a game-theoretic model in order to investigate the influence of transportation costs on distribution decisions in long-term relief operations and to evaluate measures for improving the fulfillment of beneficiary needs. The equilibrium of the model is a Generalized Nash Equilibrium, which has had few applications in the supply chain context to date. We formulate it, utilizing the construct of a Variational Equilibrium, as a Variational Inequality and perform numerical simulations in order to study the effects of three interventions: an increase in carrier competition, a reduction of transportation costs and an extension of framework agreements. The results yield important implications for policy makers and humanitarian organizations (HOs). Increasing the number of preselected carriers strengthens the bargaining power of HOs and improves impact up to a certain limit. The limit is reached when carriers set framework rates equal to transportation unit costs. Reductions of transportation costs have a consistently positive, but decreasing marginal benefit without any upper bound. They provide the highest benefit when the bargaining power of HOs is weak. On the contrary, extending framework agreements enables most improvements when the bargaining power of HOs is strong.

The master thesis is focused on processes of distribution of goods in urban areas which are generally called city logistics. The aim of the thesis is to fing out the potential of the application of city logistics in Ceske Budejovice.

Logistics play a vital role in the prosperity of today’s cities, but current urban logistics delivery practices have proven problematic and to be causing various negative effects in cities. This study proposes an alternative method for delivering cargo with the leasing of a network of logistics hubs within urban areas for designated daily time intervals and handcart last-mile deliveries. The objective of the study is the development of a mathematical programming model for identifying the optimal number and locations of hubs for serving demand with the minimum cost, as well as the optimal times during the day for leasing the facilities, while also allocating hubs to customers. The problem is effectively solved by applying a Lagrangian relaxation and subgradient optimization approach. Numerical examples and a sensitivity analysis provide evidence of the robustness of the model and its ability to be effectively applied to address real problems. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection
