Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in [1].

Reproducibility Variable Result LLM Response
Research Type Experimental Finally, we demonstrate the utility of our approach by comparing against two benchmark approaches on two real-world data sets of bike sharing systems. These approaches are evaluated using a simulation where the movements of customers are generated from real-world data sets.

Open Source Code No The paper does not provide a direct link to a source code repository, explicitly state that code is released, or mention code in supplementary materials for the methodology described.
Open Datasets Yes We employ data sets of two leading bike sharing systems in US11, namely, Capital Bikeshare (Washington, DC) and Hubway (Boston, MA)... 11. The data is taken from Capital Bikeshare [http://capitalbikeshare.com/system-data] and Hubway BSS [http://hubwaydatachallenge.org/trip-history-data].
Dataset Splits No The paper refers to using a "training data set" and a "test data set" but does not specify the explicit proportions, methods (e.g., random split, stratified), or sample counts for these splits. It generally discusses evaluating solutions on a simulation using the test data set and sometimes deriving solutions from the entire dataset.
Hardware Specification Yes All the linear optimisation models were solved using IBM ILOG CPLEX Optimisation Studio V12.5 incorporated within python code on a 3.2 GHz Intel Core i5 machine.
Software Dependencies Yes All the linear optimisation models were solved using IBM ILOG CPLEX Optimisation Studio V12.5 incorporated within python code on a 3.2 GHz Intel Core i5 machine.
Experiment Setup Yes The planning horizon for our approach is 38 time steps (30 minute intervals during the working hours from 5AM-12AM) for the entire day and 14 time steps for the peak period (30 minute intervals during the morning working hours from 5AM-12PM). ... we employ 5 vehicles for the experiments on Capital Bikeshare data set and 3 vehicles for the experiments on Hubway data set. ... we choose 30 minute as the default setting for the duration of time step.
