Shipping agent: Fill the load carrier that is already scheduledSupplier: Get better price on
transport with low emissions and delivered in time
Load carrier, 20% left!
Main idea with the portal
DHLDelegoEtc.
Existing systems, commercial examples, Sweden
Systems under development, an example
LogIt D2D – Interbaltic/Transbaltichttp://www.logit-systems.com
Cost and time considered in these systems
No emissions considered in these systems
List of transport alternatives minimizing the overall transport cost (in prototype)
The prototype as a starting point, only in Swedish

NOT SUPPORTED BY ANY OTHER SYSTEM!
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.

•Network model•Degree of detail: Everything is possible!
Activity 5.2: Optimization model illustration
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

Visualization of the example (activity 5.2)
Red arrows is the routes choosed by the system in real time
Three transports on the same ferry filling the trucks with additional 5, 9, 7 tons respectively
Current model status (example)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 futureActivities: 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)
•Different transport modes!•Different routes!
Choose between routes that Choose between routes that are suffiencely different are suffiencely different (activity 5.3)(activity 5.3)
Portfolio of transport alternatives!
• Considering uncertainty in model : Less disturbances!• Yes, but disturbances can never be completly avoided !• Disturbances management therefore important – portfolio of transport portfolio of transport

Before After
Activity 5.3
Test case development, start date (Activity 5.5)1. August 2011
Suppliers will be selected from these companies customers (case 1)
Test case nr 1
Other test cases (next slide): Discussions initiated with Finnish and norweigan partners in august 2011Reference groups will
consists of financers and the involved companies
The other possible test cases
Case 2: Special transports in Osterbotnia with Finnish partners
Case 3: A case study in Norway toghether with Norweigan partners
Case 4: Food transports in the corridor with partners from all countries
Interested actors outside the project
Rauma- Gävle ports, Route 61

Cooperation regarding portal devlopment
Contact have been etablished with the Transbaltic Wp 5.3 (Deployment of ICT toolbox)-Poznan, Poland
Model development in cooperation with researchers at Stockholm Univeristy (joint research group)
Required data to test the portal: Small example included in red
Exempel på vad som behövs för beräkning, programmet kan samtidigt minimera transporttid, emissioner eller transportkostnad/Example on what is required for calculations, programme can jointly optimize transporttime, emissions and transportcost

Information
As indicated above route=leg is possible but not required in modelModel today can handle multiple transports In current model cost is minimzed given that a certain amount of CO2 and time restrictions is metMore information in the slidesThe model is general and can handle a lot of transports simultanousely as indicated in the example explained in powrpoint presentation
This is the data needed to test the current portal. Additional data can be added as needed. The model to match the transports are very general and can be extended in many directions
• First demonstration with real data planned for january 2012
• First article is under review in the scientific journal Transactions on Intelligent Transportation Systems.
• This presentation is an extension for internal use in the project of the presentation at the MCDM 2011 conference in Jyväskylä, Finland, 13-17 june 2011
