1. 41. Towards a capability approach to mobility : An analysis of disparities in mobility opportunities among older people

   Författare :Jean Ryan; Anders Wretstrand; Steven Schmidt; Karen Lucas; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility; Ageing; Transport equity; Capability Approach; Public transport; Cycling; Older people; Mobility; Ageing; Transport equity; Capability Approach; Public transport; Cycling; Older people;

   Sammanfattning : Older people represent a greater proportion of the population than ever before. In Sweden, one in five is now aged 65 and above, and more than one in seven is aged 65-79. This demographic change has challenged and will challenge society, presenting sizeable tasks for the transport sector. LÄS MER

3. 42. A Simulation-Optimization Approach for Improved Robustness of Railway Timetables

   Författare :Johan Högdahl; Markus Bohlin; Oskar Fröidh; Alireza Ahmadi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railroad; Timetabling; Optimization; Simulation; Robustness; Punctuality; Delay prediction.; Järnväg; Tidtabelläggning; Optimering; Simulering; Robusthet; Punktlighet; Förseningsprediktion.; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

   Sammanfattning : The timetable is an essential part for the operations of railway traffic, and its quality is considered to have large impact on capacity utilization and reliability of the transport mode. The process of generating a timetable is most often a manual task with limited computer aid, and is known to be a complex planning problem due to inter-train dependencies. LÄS MER

4. 43. Service i glesbygd : trender och planeringsmöjligheter

   Författare :Ulf Wiberg; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accessibility; rural planning; sparsely populated areas; urban-place-system; commercial services;

   Sammanfattning : The major aim of the thesis is to study various issues regarding the supply of services in the rural areas of Northern Sweden characterized by sparse population. Localities in these areas represent the lowest hierarchical units in the urban-place-system. LÄS MER

5. 44. The value of information sharing in automotive supply chains: Understanding the role of information utilisation for operations planning and control

   Författare :Paulina Myrelid; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; information sharing; information utilisation; automotive industry; planning processes; information quality; performance; buyer-supplier relationships; operations planning and control;

   Sammanfattning : The purpose of the thesis is to provide knowledge about the role of information utilisation in suppliers’ operations planning and control (OPC) processes, for generating value of shared demand-related information in automotive supply chains. To do so, the thesis focuses on information utilisation from three different perspectives: (1) how suppliers utilise shared information; (2) why they utilise the information the way they do; and (3) the effect of the utilisation.

7. 45. Large-Scale Road Network Vulnerability Analysis

   Författare :Erik Jenelius; Lars-Göran Matsson; Michael G. H. Bell; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; vulnerability; risk reliability; transport; infrastructure; road network; Other social sciences; Övrig samhällsvetenskap;

   Sammanfattning : Disruptions in the transport system can have severe impacts for affected individuals, businesses and the society as a whole. In this research, vulnerability is seen as the risk of unplanned system disruptions, with a focus on large, rare events. LÄS MER
