Benchmark dataset for production planning and detailed scheduling in process industries

This dataset is intended for research on production planning (PP) and detailed scheduling (DS) in process industries. It is derived from the Westenberger-Kallrath (WK) problem, a prominent case from the chemical process industry, and it is enhanced with additional data regarding customer due dates, sales prices, and costs factors for production, storage and raw material purchase. The size of the problem instances is determined by the customer order count. The folder "generated-dataset" contains all generated problem instances. Each file name contains the number of customer orders and a reference if a low-margin or a high-margin price profile was applied. All text files are mapped to optimization tasks in the Excel file "overview-instance-files". An explanation on the different optimization tasks is provided in the Excel file "overview-optimization-tasks". The folder "source-data" contains all primary data from other scientific resources, which were used in data generation process. The folder "task1-no-prices" contains two special problem instances with 40 customer orders, following the pattern of "kallrath2002-instance-task1.txt". For one instance, the divergent material flow is de-activated, hence, it contains only linear and convergent material flows.
