2. 1. Collaborative Tracking and Tracing – A Supply Chain Perspective

   Author : Vahid Mirza Beiki; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; logistics; wagon; rail; design.; supply chain; entities; collaborative; food; tracking and tracing T T ; actors;

   Abstract : The purpose of this thesis is to explore tracking and tracing (T&T) systems to develop the concept of “collaborative tracking and tracing” for the management of logistics operations.The thesis is based on extensive literature reviews, and four major empirical studies, including one structured interview study, one documentation review study, case studies of two Swedish fresh-fish supply chains (SCs) and a case study of the Volvo cars body components (VCBC) SC.

4. 2. Modelling and laboratory investigations on freight wagon link suspensions with respect to vehicle-track dynamic interaction

   Author : Per-Anders Jönsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; freight wagon; running gear; link suspension; laboratory test; ; Other engineering mechanics; Övrig teknisk mekanik;

   Abstract : The link suspension is the most prevailing suspension system for freight wagons in central and western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. READ MORE

6. 4. Unsteady Numerical Simulations of Flow around Heavy Vehicles, Trains and Passenger Cars

   Author : Jan Östh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large Eddy Simulation; fluid dynamics; bluff body flows; flow structures; vehicle aerodynamics; flow control; flow physics; truck aerodynamics; train aerodynamics; car aerodynamics;

   Abstract : In this thesis several simulations have been carried out aimed at improving the knowledgeof vehicle aerodynamics and improving the flow around vehicles with respect to theaerodynamic drag. Four flows around different simplified vehicles have been considered. READ MORE

7. 5. Applying Data Analytics to Freight Train Delays in Shunting Yards

   Author : Niloofar Minbashi; Markus Bohlin; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; delay prediction; congestion; delay probability distributions; temporal delay distributions; Rangergodsbangårdarna; förseningsprediktion; trängsel; fördröjning av sannolikhetsdistributioner; tidsfördröjningsdistributioner; Transportsystem; Transport Systems;

   Abstract : The European Commission has foreseen a modal share of 30% by 2030 for rail freight transport. To achieve this increase in the modal share, enhanced reliability of rail freight services is required. Optimal functioning of shunting yards is one of the areas that can improve this reliability.
