An Improved Algorithm for Open Online Dial-a-Ride
, 2022 We consider the open online dial-a-ride problem, where transportation requests appear online in a metric space and need to be served by a single server. The objective is to minimize the completion time until all requests have been served. We present a new, parameterized algorithm for this problem and prove that it attains a competitive ratio of $1 + φ ...

On Optimizing a Demand Responsive Transport with an Evolutionary Multi-Objective Approach [PDF]
, 2010 6 pagesInternational audienceThis paper deals with a dial-a-ride problem with time windows applied to a demand responsive transport service. An evolutionary approach as well as new original representation and variation operators are proposed and detailed.

How FDI reshapes host markets’ trade profile and politics
American Journal of Political Science, EarlyView.Abstract A fast‐growing literature indicates that firms’ engagement in foreign direct investment (FDI) and trade is key to understanding deepening global value chains and their political implications. However, existing studies have mainly focused on the ramifications for FDI home countries while often overlooking the firm‐product level interactions ...

Exploring on-demand service use in large urban areas: the case of Rome [PDF]
Archives of Transport, 2019 Traditional and innovative on-demand transport services, such as taxi, car sharing or dial-a-ride respectively, can provide a level of flexibility to the public transport with the aim to guarantee a better service and to reduce the exploitation costs. In

Innovative systems for the transportation disadvantaged: towards more efficient and operationally usable planning tools [PDF]
, 2004 When considering innovative forms of public transport for specific groups, such as demand responsive services, the challenge is to find a good balance between operational efficiency and 'user friendliness' of the scheduling algorithm even when ...

Networks, Volume 87, Issue 2, Page 111-130, March 2026.ABSTRACT This work considers branch‐price‐and‐cut algorithms for variants of the vehicle‐routing problem in which subset‐row inequalities (SRIs) are used to strengthen the linear relaxation. SRIs often help to substantially reduce the size of the branch‐and‐bound search tree.

Journal of Neuropsychology, Volume 20, Issue 1, Page 284-290, March 2026.Abstract We describe a peculiar contralesional drawing disorder in three patients affected by focal brain lesions, who did not show signs of unilateral neglect at standard clinical assessment, including the star cancellation test. This picture, that could be termed selective constructional hemi‐apraxia (CHA), could follow both right and left‐hemisphere

A tight formulation for the dial-a-ride problem
European Journal of Operational ResearchRidepooling services play an increasingly important role in modern transportation systems. With soaring demand and growing fleet sizes, the underlying route planning problems become increasingly challenging. In this context, we consider the dial-a-ride problem (DARP): Given a set of transportation requests with pick-up and delivery locations, passenger

Hybrid search and the dial-a-ride problem with transfer scheduling constraints [PDF]
, 2015 In a conventional dial-a-ride-system passengers are moved with the same vehicle between their pickup and their drop-off location. In a dial-a-ride-system with transfer, it is possible (or even standard) that passengers change the vehicle once or several ...
