Flexible Assembly Scheduling Dataset

This dataset contains anonymized benchmark instances and experimental results used for the evaluation of scheduling algorithms in the context of assembly scheduling. The data were generated during computational experiments designed to compare multiple heuristic and metaheuristic approaches for solving assembly scheduling problems, including transformed variants of established benchmark datasets (e.g., Hurink V-data) and two-stage multi-machine assembly scheduling problem. The dataset includes detailed instance descriptions and performance metrics, such as makespan and computational runtime, for several scheduling strategies. Each instance description is provided in a JSON format with the following structure: { "name": string, # short product name - not used "code": string, # product code - not used "pname": string, #l ong product name - not used "operationid": integer,# operation unique identifier "productid": integer, # real product id reference - not used "parentid": null, # parent opperation "start_date": string, # release date e.g. 2022-08-20 00:00:00.000000 "delivery_date": string, # due date e.g. 2022-09-01 00:00:00.000000" "quantity": integer, # quantity to be produced "machines": [ # list of machines where the operation can be executed { "id": integer, # machine identifier "name": string, # machine name "execution_time": integer, # machine execution time for a unit ofproduct "setup_time": integer, # machine setuptime for current opreration "oee": real, # Overall Equipment Effectiveness - real value between in [0,1] - not used } ], "metainfo": { "operations_list": [ #contais the operations IDs ], "machines_list": [ #contais the machine IDs ], "maintenances": [ #list of maintenance interval - not used { "id": integer, # maintenance ID "machineid": integer, # machine ID on which the maintenances is scheduled "start_date": string, # maintenances start time e.g. 2022-08-25 14:00:00.000000 "end_date": string, # maintenances stop time e.g. 2022-08-25 15:00:00.000000 }, ] }, "children": [ # list of operation succesors { "name": string, # short product name - not used "code": string, # product code - not used "pname": string, #l ong product name - not used "operationid": integer,# operation unique identifier "productid": integer, # real product id reference - not used "parentid": null, # parent opperation "quantity": integer, # quantity to be produced "machines": [ # list of machines where the operation can be executed ] ]} The dataset is intended to support the reproducibility of experimental results and to facilitate further comparative studies in scheduling and combinatorial optimization.
