Landside operations in air cargo terminals consist of many freight forwarders (FFWs) delivering and picking up cargo at the capacity-constrained loading docks at the airport's ground handlers' (GHs) facilities. To improve the operations of the terminal and take advantage of their geographical proximity a small set of FFWs can build a coalition to consolidate stochastically-arriving shipments and share truck fleet capacity while other FFWs continue bringing cargo to the terminal in a non-cooperative manner. Results from a detailed discrete-event simulation model of the cargo landside operations in Amsterdam Aiport showed that all operational policies had trade-offs in terms of the average shipment cycle time of coalition FFWs, the average shipment cycle time of non-coalition FFWs, and the total distance traveled by the coalition fleet, suggesting that horizontal cooperation in this context was not always beneficial, contrary to what previous studies on horizontal cooperation have found. Since dock capacity constitutes a significant constraint on operations in air cargo hubs, this paper also investigates the effect of dock capacity utilization and horizontal cooperation on the performance of consolidation policies implemented by the coalition. Thus, we built a general model of the air cargo terminal to analyze the effects caused by dock capacity utilization without the added complexity of landside operations at Amsterdam Airport to investigate whether the results hold for more general scenarios. Results from the general simulation model suggest that, in scenarios where dock and truck capacity become serious constraints, the average shipment cycle times of non-coalition FFWs are reduced at the expense of an increase in the cycle times of FFWs who constitute the coalition. A good balance among all the performance measures considered in this study is reached by following a policy that takes advantage of consolidating shipments based on individual visits to GH.
What is this publication about?In this publication on ‘New urban economies’, we search for answers and insights to a key question: how can cities foster economic development and develop ‘new urban economies’. And, importantly, how can they do that:◗ in concertation with different urban stakeholders, ◗ responding adequately to key challenges and developments beyond their control, ◗ building on the cities’ own identity, industries and competences, ◗ in a sustainable way, ◗ and without compromising weaker groups.
The objective of this research is to advice the Municipality of The Hague whether, if and under which conditions, the implementation of an Urban Consolidation Centre (UCC) is possible and desirable. To determine factors that caused the success or failure of UCCs in practice, a survey of 6 cases in Europe is conducted. The cases were selected because of the similarity of the service area of the UCC and the city centre of The Hague or because of the uniqueness of the UCC. To determine the possible success for a UCC in The Hague four scenarios are evaluated. Two major difficulties with implementing the UCC are the allocation of the costs and benefits and the willingness to cooperate of the transportation companies. Both consignees and transportation companies can benefit financially from using the UCC. The UCC operator, however, incurs the costs. The municipality should play a role in bringing the costs and benefits together. © 2010 Elsevier Ltd. All rights reserved.

1. Evaluate priority incentive electrical taxis: Bji het Centraal Station is reeds een voorrangsincentive voor elektrische taxis ingesteld. Gedurende deze case zullen we het effect de huidige regeling toetsen en nagaan wat het effect is op kosten en baten alsmede business case van de e-taxi. Daarnaast zal een technische ontwerpstudie van een dergelijke standplaats onderdeel van dit subproject zijn. 2. Strategic placement of (semi) public charge infra in ArenA Area: In deze case wordt onderzocht op welke manier de laadpalen kunnen bijdragen aan het reguleren van verkeer richting de ArenA en waar deze laadpalen gepositioneerd dienen te worden. 3. Consolidation of city logistics at ArenA Area; In deze case wordt de haalbaarheid onderzocht van incentives op logistieke dienstverleners. Bij welke incentives is het voor vervoerders interessant om over te stappen op elektrisch vervoer? 4. Pilot incentive exemption from parking tax: Hierbij wordt de prijsprikkel “ontheffing van parkeerbelasting”, die de gemeente Amsterdam wil inzetten ter bevordering van e-taxis, onderzocht en gemonitord, waarbij kosten en baten worden vergeleken. 5. Determine hotspot location for e-taxi’s: Incentive-beschikbaarheid- Bepaling van meest kansrijke en faciliterende laadlocaties op basis van ritgegevens van taxi's (hotspot) inclusief vaststelling van eisen/wensen voor de laadfaciliteiten (e.g. (snel)laders) inclusief monitoring van het gebruik na plaatsing.
