Program outline
• Main policy questions
• What are logistical needs of the companies in and around the Randstad?
• What facilities are needed to create a sustainable freight network?
• How can we secure the sustainable accessibility of cities for freight?
• Research challenges
• Improve policy support tools, i.e.
• create new data and models for policy analysis
• Generate insights relevant for the Randstad
• Objective: improve tools at four levels
•

•
International trade
Distribution chains
Multimodal transport networks

2 Multimodal networks
(Mo Zhang,
Bart Wiegmans/LT)
3 City Logistics
(Nilesh Anand,
Ron van Duin)
Production- of consumption location
Warehouse
Transshipment between modes
Contractual relation
Physical transport relation
Route driven
Interregional commodity flows (Maureen Lankhuizen)
• Challenge
NL
Region S
Df
World
r
• Integration of transport
statistics and trade statistics
• Model
Ds
Internatio
nal
S
f
Production in region r for consumption in s
Production in region r destined for export
Imports destined for region s
International transit through the Netherlands
• MRIO framework
• international chains
• separation of production from
transit
• Insights
• container contents
• “death of distance”
• spatially homogeneous
commodity groups
• New CBS publication

Model of distribution center use (Igor Davydenko)
• Challenge
• Can aggregate patterns be
reproduced?
• Model
•
•
•
•
•
Total Logistic Cost based
Simple aggregate logit
NL: transport survey CBS
D: retail chains (firm level)
EU: transport & trade stats
• Insights
•
•
•
•
Land use effects (sprawl)
Share of HGV trips (NL: 14%)
Impacts spatial flow patterns
Road vkm elasticity
5
Supernetwork design (Mo Zhang)
• Challenge
• Extending network design
methods for Randstad
• Model
Rodrigue & Notteboom, 2010
• TLC based multi-commodity,
intermodal network design
• Scale economies at terminals
• Calibration of demand model for
terminals
• Insights
-- 20% CO2 @ 150 €/t
•
•
•
•
•
Co-operation and capacity
GHG/TLC trade-off
Effect of pricing policies
Rail/waterways competition
Price elasticities intermodal

Multi-agent system for city logistics (Nilesh Anand)
• Challenge
Multistakeholder
stakeholder
stories
stories
• An ABM for city logistics that
recognizes multi-actor aspect
• Model
Functional
ontology

Gaming
application
application
• Multi-stakeholder ontology
• ABM consistent with ontology
• Validation and gaming
• Insights
• Ontology based approach allows
development of shared business
models
• Invest in common language &
shared design
• Next: global city logistics

Concluding remarks
• Supply chain perspective on freight models
• Key for public interest: understand origins and future of industry choices.
• Key for industry interest: operational and tactical level optimization, and
demand intelligence
• Dissemination and exploitation
• Several journal and conference papers
• Dutch roadmap for freight models
• Move towards models based on
• Logistics (costs +service based) decisions
• Dynamics and big data
• Multi-stakeholder perspectives
