Job Shop Instances with Varying Job and Operation Entropy

This dataset contains multiple sets of job shop problem instances with varying characteristics. Instances have been generated for various target inter-instance job entropies, intra-instance job entropies, inter-instance operation entropies, and intra-instance operation entropies. For reference, the dataset also contains randomly generated job shop instances. More information about the data generation and the used terminology can be found in the accompanying data publication.

Each problem instance contains the following information in json-format:

id: a unique id for each generated problem instance

opt_time: the optimal makespan for the problem instance determined by Google ORTools

intra_instance_operation_entropy: the intra-instance operation entropy of the instance

num_ops_per_job: the number of operations of each job max_op_time: the maximum processing time of all operations

machine_types: the type of machine required for each operation in each job

durations: the processing time of each operation in each job
