Konferensbidrag (refereegranskat)abstract
- Technology alone will not be sufficient to cope with emission reduction challenges. Transport procurement requires attention for individual firms as well as the transport industry to tackle environmental challenges. The aim of this paper is to identify practice, perceptions and outlook of transport buyers in order to present a research agenda that informs the advancement of current practice, on the basis of surveys, capturing practice among Swedish transport buyers. The direction for future research comprise levels of analysis ranging from the service level to industry-level, and suggest a mixed-method, wherein surveys are combined with in-depth case studies and workshops.

Intressent- och behovsanalys för resvaneundersökningar : resultat från intervjuer och enkätundersökning
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I Sverige genomförs en nationell resvaneundersökning med viss regelbundenhet med Trafikanalys som ansvarig myndighet. Undersökningen har problem med bortfall, täckning, kostnader och uppgiftslämnarbörda. Ett projekt pågår som syftar till att utveckla nya metoder för att samla in data om personers mobilitet. Projektet är indelat i fem arbetspaket, varav detta arbete är ett. Syftet är att utföra en intressent- och behovsanalys avseende framtida resvaneundersökningar. I detta ingår att identifiera syften och frågeställningar som resvaneundersökningar ska kunna hantera och besvara.Det genomfördes 20 telefonintervjuer och utskick av webbenkät till 142 personer (svar från 81 personer, svarsfrekvens 57 procent). Intressenterna delades in i tre olika grupper: offentlig sektor, forskningsorganisation och övriga aktörer. Tillsammans med egna erfarenheter har en analys gjorts av vad som efterfrågas från den nationella resvaneundersökningen. Frågeställningar som centrala för användare av resvaneundersökningar är val av färdsätt, resans ärende samt mått på hur resvanorna förändras över tid och hur olika grupper reser. För detta behövs både uppgifter om individen och resorna. Utöver detta önskar man bra data på kommunal nivå eller lägre. Dock kan Trafikanalys i nuläget inte erbjuda den möjligheten, men här finns det möjlighet för kommuner, regioner och andra aktörer att välja ett extraurval från den befintliga nationella resvaneundersökningen.

Köpa mat online? : effekter av ökad e-handel för person- och godstransporter i ett växande e-handelssamhälle
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- De senaste åren har e-handel av livsmedel ökat starkt. Idag bygger beräkningar om e-handelns energieffekt på uppskattningar och antaganden snarare än på kunskap om branschen och dess kunder. Den här studien genererar fördjupad kunskap om vad det ur ett transportperspektiv innebär att företag istället för individer ansvarar för att matvaror transporteras till hemmet. Huvudsyftet med projektet är att analysera effekter till följd av ökad e-handel av livsmedel samt synliggöra faktorer som möjliggör en realisering av eventuell energibesparing. Detta görs ur ett regionalt perspektiv och i en svensk kontext. Syftet har uppnåtts genom en studie av energieffektiva distributionslösningar för e-handelserbjudanden, och genom en intervjustudie om potentiella och befintliga e-handelskunders preferenser, erfarenheter och beteende samt genom framtagandet av en regional modell för persontransporter.Resultaten pekar på att e-handel har betydande teoretisk potential givet att effektiva rutter ersätter inköpsresor med privat bil. Idag innebär många kompletteringsresor med bil att e-handeln inte i någon högre grad ersätter inköpsresorna, vilket innebär att energibesparingen idag sannolikt är begränsad. För att potentialen ska kunna uppnås behövs ett utökat kundunderlag, en medveten stadsplanering som prioriterar gång-, cykel- och kollektivtrafik, som lyfter godstransporter som en strategisk fråga och som lokaliserar livsmedelsbutiker nära människors hem.

Providing explicit descriptions of studied systems: more than a necessary evil?
- 2015
-
Ingår i: Nofoma Conference Proceedings. - 9788279622024
-
Konferensbidrag (refereegranskat)abstract
- PurposeExplicit descriptions of studied systems can support researchers in clarifying objects of study and motives of research as well as in structuring research design. However, since many scholars of systems approaches operate outside the field of logistics, applying systems approaches in logistics can be challenging. The purpose of this paper is therefore to describe how a systems approach can be applied in logistics so as to provide guidance for logistics researchers in their descriptions of studied systems.Design/methodology/approachTwo systems approaches were used to describe the systems studied in six doctoral theses. A series of workshops was conducted to compare the descriptions and share challenges.FindingsKey aspects for adapting the selected systems approaches corresponded to four areas of logistics—activities, flow, performance, and actors—all of which can be included in the selected systems approaches. Advice for doctoral students on applying these frameworks is provided.Research limitations/implicationsThis research can provide support to other logistics researchers when applying systems approaches and developing explicit descriptions of studied systems.Original/valueSystems approaches are central to logistics research, a field in which scholars are encouraged to apply well-known systems approaches. This paper contributes value by providing explicit examples of how such approaches were applied in six logistics research projects.

Comparing flexibility-based measures during different disruptions: evidence from maritime supply chains
- 2024
-

Tidskriftsartikel (refereegranskat)abstract
- This paper’s purpose is to explore flexibility-based countermeasures that enable actors in maritime supply chains to mitigate the effects of disruptions with different characteristics. Semi-structured interviews were conducted with shipping lines, shippers, forwarders and ports. Data on the COVID-19 pandemic’s effects and countermeasures were collected and compared with data regarding the 2016–2017 Gothenburg port conflict. Spatial, capacity, service and temporal flexibility emerged as the primary countermeasures, whilst important characteristics of disruptions were geographical spread, duration, uncertainty, criticality, the element of surprise and intensity. Spatial flexibility was exercised in both disruptions by switching to alternative ports. During the COVID-19 pandemic, ensuring capacity flexibility included first removing and then adding vessels. Shipping lines exercising service flexibility prioritised certain cargo, which made the spot market uncertain and reduced flexibility for forwarders, importers and exporters that changed carriers or traffic modes. Experience with disruptions meant less surprise and better preparation for spatial flexibility. Comparing flexibility-based measures in a pandemic versus port conflict provides insights into the important characteristics of disruptions and the relevance of mitigation strategies. The resilience of maritime supply chains, although underexamined compared with manufacturing supply chains, is essential for maintaining global supply chain flows.

Connecting ordering of freight transport to logistical variables related to CO2 emissions
- 2012
-
Ingår i: Proceedings of the LRN Conference, Cranfield, 5-7 September 2012.
-
Konferensbidrag (refereegranskat)abstract
- Purpose: Reducing environmental impact is increasingly important for companies and this includes concerns regarding emissions from purchased freight transport services. When shippers order freight transport services, according to purchasing agreements, shipment specific requirements are specified, which can restrict the planning options of the transport provider, thereby influencing how the transport is performed and the resulting environmental performance. Therefore, shippers’ daily processes for ordering freight transport are of interest. The purpose of this paper is to explore how the shipper´s freight transport ordering process influences the logistical variables in the framework of Piecyk and McKinnon (2010): modal split, handling factor, average length of haul, lading factor, empty running, fuel efficiency and carbon intensity of fuel, in order to understand in what way CO2 emissions can be affected by the freight transport ordering process. Research approach: An explorative multiple case study of routine freight transport ordering processes at manufacturing companies was carried out. Shippers were interviewed to describe the transport ordering process as well as how related internal processes provide input to the process. The analysis combines the information from the cases with literature that describes logistical variables, and results in a description of how the transport ordering process can influence logistical variables. Findings and Originality: The study identified several connections from the freight transport ordering process to logistical variables and that the potential to reduce CO2 emissions partly depends on input from other processes. Examples of findings are, first, that timing of information input to the transport ordering process regarding transport requirements can influence lading factor and empty running, by affecting opportunities for the transport provider to plan vehicle utilisation. Secondly, communication between the sales staff and the transport ordering staff about customer needs regarding delivery times can affect urgency of transport and thereby influence modal split. Thirdly, information input to the transport ordering process regarding dimensions can affect planning of space required for the shipment and the utilisation of ordered space, thereby influencing lading factor. Research impact: The paper contributes by process descriptions of the freight transport ordering processes, which has been rarely covered in previous research. Also, a general model of the process is proposed. It also contributes to the framework used by Piecyk and McKinnon (2010) by showing influence from the transport ordering process on logistical variables. Practical impact: Shippers can learn how the configuration of the freight transport ordering process can influence logistical variables. This is important in order to be able to configure the freight transport ordering process to accommodate environmental considerations and reduce CO2 emissions from freight transport.

Ingår i: Proceedings of the 20th Annual IPSERA Conference, Maastricht, April 10-13, 2011.
-
Konferensbidrag (refereegranskat)abstract
- The purpose of this paper is to identify contextual factors that may influence the freight transport purchasing process and develop a model for positioning transport purchasing process and practices with respect to the context. Based on well established supply chain models, data from six case companies is used to explore the links between contextual factors and how the purchasing of freight transport is performed. Important contextual factors identified in the case companies include cost, service, product characteristics and material flow.

Environmental concerns when purchasing freight transport
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Companies that purchase freight transport (shippers) influence the conditions for how transport providers can execute the transport, which in turn influences CO2 emissions. The conditions can be influenced both by shippers’ purchasing processes for freight transport and when shippers prepare goods for delivery. For shippers to make appropriate decisions aimed at reducing the CO2 emissions from their transport, clarification of such influences on the conditions are necessary. The purpose of this thesis is to clarify how shippers can influence CO2 emissions from the freight transport they purchase. This thesis is a compilation of seven papers, six of which are based on empirical data from five multiple-case studies. The data collection mainly consisted of semi-structured interviews with shippers’ logistics, transport, and purchasing managers, as well as with staff in operational positions; one study also conducted interviews with transport providers. The seventh paper reports on a structured literature review of load factor. Together these studies answer four research questions. The first research question is concerned with how contextual factors influence shippers’ freight-transport-purchasing processes. The results describe the purchasing process in contexts that vary in service type, purchase situation, and relationship. The second research question examines how shippers’ freight-transport-purchasing processes influence various logistical variables (mode of transport used, handling factor, length of haul, load factor, empty running, fuel efficiency, and carbon in fuel). The causes of different influences on logistical variables (such as specified time requirements) are clarified by answering this question. The third research question concerns how shippers can identify and evaluate opportunities to increase their load factors. Achieving high load factors is a matter of balancing required and available capacity at the packaging, shipping, and vehicle levels. A framework of opportunities describes how these capacities can be increased, decreased, and reallocated, thus allowing for the identification and comparison of relevant opportunities. The fourth research question is concerned with how shippers’ internal coordination may enable high load factor. The use of coordination mechanisms is described in situations that differ in terms of dependence between activities, number of activities, and the need for intra- or interfunctional coordination. The results contribute to green-logistics research in terms of improving load factor and the purchasing of freight transport. Different research streams and perspectives – especially in terms of purchasing, transport, and coordination – have been combined in this thesis. The results contribute to improving the environmental performance of freight transport by clarifying shippers’ influence on the CO2 emissions of the transport they purchase via descriptions of the shippers’ influence over logistical variables (including load factor) that in turn influence CO2 emissions.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this paper is to propose a framework for analysing the contextual influence on the configuration of purchasing processes for freight transport services. A conceptual model suggests that three contextual dimensions, purchase task, importance, and service type, influence the different stages of the purchasing process. Data from seven case companies are used to explore the links between contextual factors and how the purchasing of freight transport is performed. Eight different types of context, and their implications for the configuration of the purchasing process, are presented. The framework offers guidance on the configuration of the purchasing process in specific contexts, highlighting, for example, that the level of detail of the specification stage can depend on the type of context.
