Results and conclusions
CC-BY PER OLOF ARNÄS
The transport portfolio framework is a decision support for shippers to reduce the carbon footprint, linking logistics decision-making to environmental output, by applying a
portfolio model

Results from an ongoing study in the food industry
What can the transport buyer do to affect load factor?

Recent study of a transport buying company:
Load factor framework
Packaging efficiency
Loading efficiency
Booking efficiency
[order rows / load unit]
[load unit / used load meter]
[used load meter / booked load meter]
Product characteristics
Order variation
Lead time (time between order and delivery)
Logistics variable Load factor indicator Indicator measure
CC-BY PER OLOF ARNÄS
Vendela Santé[email protected]
Important to see the potential in each indicator, while also
looking at the whole
The framework is linking three levels of load factor
indicators to each other
Packaging
Loading
Booking
The booked load meters can be used even more
efficiently
Challenges still exist in product characteristics and order variation
Changes in lead time can improve planning possibilities and even out the flow between days

• Identification of supply chain characteristics
• A framework for supply chain configuration for a new process technology
• Identification and quantification of important parameters affecting (1) total cost (2) size of torrefaction plant and (3) location of torrefaction plants.
