Privatization and PPPS in transportation infrastructure: Network effects of increasing user fees

PPPS: Problem: Public-private-partnerships in transport infrastructure characteristically increase user-fees. Purpose: We aim to identify the network effects of the use of PPPs and increased user tolls in road infrastructure. Methods: We study the increases in user tolls on motorways due to the use of PPPs in the US. Results and conclusions: Among other things, the monetization of motorways is associated with an increase in toll levels that has consequences for their users, and also for the rest of the sections of the network.

Autovías y ferrocarriles: un modelo para evaluar efectos intermodales de la política de infraestructuras

La construcción de autovías disminuye el coste temporal del viaje por carretera, con efectos sobre la demanda del transporte por carretera. Pero, además de los efectos intramodales, existen efectos intermodales, puesto que las autovías afectan a la demanda en otros modos alternativos a la carretera. En este trabajo formulamos y contrastamos empíricamente un modelo que permite obtener resultados para evaluar el impacto de las autovías sobre la demanda de ferrocarril. Seguidamente se pronostican algunos efectos sobre la demanda ferroviaria de algunas actuaciones en infraestructuras viarias incluidas en el Plan Director de Infraestructuras (1993-2007).

When supply travels far beyond demand: Causes of oversupply in Spain’s transport infrastructure

Spain’s transport infrastructure policy has become a paradigmatic case of oversupply and of mismatch with demand. The massive expansion of the country’s transport infrastructure over the last decade has not been a response to demand bottlenecks or previously identified needs. For this reason, the intensity of use today on all interurban modes of transport in Spain falls well below that of other EU countries. This paper analyzes the institutional and regulatory factors that have permitted this policy, allowing us to draw lessons from the Spanish case that should help other countries avoid the pitfalls and shortcomings of Spanish policy.

Suurlujuusterästen hitsausliitoksen HAZ -vyöhykkeen murtumissitkeys

Suurlujuusterästen käyttö erityisesti auto-, kuljetusväline- ja nostovälineteollisuudessa on lisääntynyt jo pidemmän aikaa. Teräsvalmistajat kehittävätkin jatkuvasti lujempia ja paremmin hitsattavia teräslaatuja markkinoille. Lujempia teräksiä käyttämällä on mahdollista saavuttaa materiaali- ja painosäästöä, jolla on suora vaikutus hyötykuorman lisääntymiseen, polttoainetalouteen, suoritusarvoihin ja jopa valmistuskustannuksiin. Tässä diplomityössä tutkittiin kahdeksan eri suurlujuusteräksen ja kolmen kulutusteräksen HAZ-alueen murtumissitkeyttä kolmella eri lämmöntuonnilla tehdyllä hitsauksella. Suurlu-juusterästen myötölujuustaso vaihteli 650 MPa:n ja 700 MPa:n välillä, ja kulutusteräksillä vastaavasti 800 MPa:n ja 1000 MPa:n välillä. Murtumissitkeyskokeet tehtiin standardoidun CTOD-testausmenetelmän mukaisesti -40 °C lämpötilassa. Kokeissa käytettiin 10 mm x 5 mm SE(B)-kolmipistetaivutussauvoja. Koetuloksia voidaan käyttää apuna arvioitaessa eri teräslaatujen hitsauksellista sopivuutta erityisesti väsyttävän kuormituksen alaiseen rakenteeseen. Kokeiden tuloksena saatiin jokaiselle materiaalille neljä CTOD-arvoa. Kolmella eri lämmöntuonnilla tehtyjen koesauvojen lisäksi mitattiin ilman hitsausta olevista koesauvoista perusaineen murtumissitkeys. Yhteensä CTOD-koe tehtiin 44 koesauvalle ja lisäksi muutamalle harjoitussauvalle. Testattavien kappaleiden suuren määrän takia kokeet voitiin tehdä jokaiselle materiaali- lämmöntuonti- yhdistelmälle ainoastaan yhteen kertaan.

Optimization of Transportation System by Tailored Logistics Network: A Case Study in Automotive Industry

This thesis aims to redesign the supply chain system in an automotive industry in order to obtain space reduction in the inventory by using tailored logistics network. The redesigning process by tailored supply chain will combine all possible shipment methods including direct shipment, milk-run, milk-run via distribution center and Kanban delivery. The current supply chain system in Nissan goes rather well when the production volume is in moderate level. However, when the production volume is high, there is a capacity problem in the warehouse to accommodate all delivered parts from suppliers. Hence, the optimization of supply chain system is needed in order to obtain efficient logistics process and effective inventory consumption. The study will use primary data for both qualitative and quantitative approach as the research methods. Qualitative data will be collected by conducting interviews with people related to procurement and inventory control. Quantitative data consists of list of suppliers with their condition in several parameters which will be evaluated and analyzed by using scoring method to assign the most suitable transportation network to each suppliers for improvement of inventory reduction in a cost efficient manner.
