Pseudocode Yes Algorithm 1: CB Decomposition for MTM
Open Source Code No The paper mentions developing a simulator but does not provide any concrete access information (link or explicit statement) to the source code for the described methodology.
Open Datasets No We use historical 55-day AIS data for Singapore Straits that records the location of each ship within Straits and port waters at every 5 second interval over 55-days. [...] From the records of each day, we perform the following to create scheduling instances. [...] The paper describes the use of historical AIS data but does not explicitly state that this dataset is publicly available or provide access information such as a link or citation for public access.
Dataset Splits No The paper describes generating synthetic instances and processing real AIS data, but does not explicitly state training, validation, or test dataset splits or specific splitting methodologies needed for reproduction.
Hardware Specification No The paper states that the approaches were 'implemented using CPLEX 12.7' and 'CP Optimizer 12.7' but does not provide any specific hardware details such as GPU/CPU models, memory, or cloud resources used for the experiments.
Software Dependencies Yes Using these synthetic instances, we compare the performance of the combinatorial Benders approach (implemented using CPLEX 12.7) against classical Benders decomposition and the baseline CP approach (implemented using CP Optimizer 12.7).
Experiment Setup Yes The settings for the three sets of instances are as follows. For all instances, the capacity of each edge is uniformly generated between 1-3, and the minimum time to traverse an edge is sampled uniformly from [5sec, 10sec]. The maximum is set to twice the minimum. The release time of each vessel is uniformly generated between 0-20 seconds, and each activity consumes 1 unit of resources.
