  1. 1. On Supply Chain Incentive Alignment: Insights from a cash supply chain and a trucking service supply chain

    Författare :Johan Lundin; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supply chain management; Incentive alignment; Cash supply chain; Trucking service supply chain; Mixed methods research;

    Sammanfattning : This dissertation presents a framework for describing, a process for identifying, and a model for evaluating misalignments in the supply chain when varying elements such as structure, processes, and management components. The developed approach makes it possible to address and improve the alignment of supply chain structures, processes, and management components. LÄS MER

  3. 2. Purchasing practices of environmentally preferable transport services, Guidance to increased shipper considerations

    Författare :Maria Björklund; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Industriell ekonomi; Commercial and industrial economics; Shippers perspective; Logistics Management; Transport services; Green Purchasing; Purchasing; Environment; Teknik; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; TECHNOLOGY;

    Sammanfattning : The logistical activity of transport is one of the largest contributors to several environmental problems. One efficient and effective way to decrease the environmental impact from transports is to implement changes in the logistically related strategies and activities applied, such as the selection of transport suppliers.

  4. 3. Lokal kollektivtrafik på samhällsekonomisk grundval

    Författare :Anders Ljungberg; Jan Owen Jansson; Bengt Mattsson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Local public transport; Cost-benefit analysis; Straighter bus-routes; Staggered school hours; Peak-load pricing; Zero fare; Lokal kollektivtrafik; Samhällsekonomisk kalkyl; Varierad skolstart; Optimal prissättning; Nolltaxa; Economics; Nationalekonomi;

    Sammanfattning : Förutom i Stockholm uppvisar den lokala kollektivtrafiken en nedåtgående trend i trafikutvecklingen, trots en årlig subvention om 10 miljarder kronor. Drift av lokal kollektivtrafik i mindre och medelstora städer baserat på samhällsekonomiska kriterier skulle bl a medföra en prispolitik som kräver en subvention om drygt 50%. LÄS MER

  5. 4. 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

  7. 5. Design and Optimization of In-Cycle Closed-Loop Combustion Control with Multiple Injections

    Författare :Carlos Jorques Moreno; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Combustion; Pilot-Main Injection; Pilot Mass Estimation; Cylinder Volume Estimation; Bayesian Estimation; In-Cycle Combustion Controllability; In-Cycle Combustion Control; Model Predictive Combustion Control; Stochastic Combustion Optimization; Hardware Quantification;

    Sammanfattning : With the increasing demand of transportation, biofuels play a fundamental role in the transition to sustainable powertrains. For the increased uncertainty of biofuel combustion properties, advanced combustion control systems have the potential to operate the engine with high flexibility while maintaining a high efficiency and robustness.
