Web based matching of transports
Leif Olsson
Main idea with the portal
60% left!
Shipping agent: Fill the load
carrier that is already scheduled
Supplier: Get better price on
transport with low emissions
and delivered in time
Load carrier, 20% left!
Existing systems, commercial
examples, Sweden
DHL
Delego
Etc.
Systems under development,
an example
LogIt D2D –
Interbaltic/Transbaltic
http://www.logitsystems.com
Cost and time
considered in these
systems
No emissions
considered in these
systems
The prototype as a starting point, only in Swedish
List of transport
alternatives
minimizing the overall
transport cost (in
prototype)

1. Intermodality
2. Conflict between criterias
3. Uncertainty
Note: This is only an example to illustrate the
problem, for instance, cost for different transport
modes depends on the length of the actual
transport etc.
GUI today, also in english etc (activity 5.4)

Activity 5.2
The routes in the
current example
(extension of
prototype model)
• 7 Routes
• 55 Distinct legs
• Intermodal
• Train, Ferry, Truck
•Minimizing total
transport cost
•Emissions and
delivery time as
constraints

Current model status (example)
•
•
•
•
No uncertainty considered
Only minimizing the transport cost
But emissions and time is included as constraints
Will be integrated with the portal summer of 2011 (activity 5.1)
Activities: Current and future
• How to handle
– Uncertain transportation time
– Multiple Criterias (Cost, Time, Emissions)
– Considered in activity 5.3 starting in august 2011
• GUI developed so that multiple transports can be considered
(not possible today, activity 5.4)
Choose between routes that
are suffiencely different
(activity 5.3)
•Different transport modes!
•Different routes!
Portfolio of transport
alternatives!
Activity 5.3
• Considering uncertainty in model : Less disturbances!
• Yes, but disturbances can never be completly avoided !
• Disturbances management therefore important – portfolio of transport
alternatives!

Uncertainty

Test case nr 2 and nr 3:
Discussions initiated with
Finnish partners in june
2011
• First demonstration with real data planned for january 2012
• First article was submitted 1 june 2011 to the International Journal of
Information Technology & Decision Making
•This presentation is from the MCDM 2011 conference in Jyväskylä,
Finland, 13-17 june 2011
