EN The article is the preliminary research results determining the influence of selected criteria on the timeliness of customer orders, the workstation load and the required size of the finished products warehouse. The criteria included in this paper are the changeover time and the priority rule. The literature analysis covers issues related to the priority rules and machine changeover. The following part of the work presents the adopted research methodology, production process model and input data. Production plans were prepared successively and 9 model variants were designated, with different changeover times and priority rules applied. The work also simulated the production process in the FlexSim program, using previously prepared production plans. For the evaluation of the models, a summary of the obtained results was taken into account, showing the timely execution of customer orders, the workstation load and the required size of the finished products warehouse. The article ended with conclusions, in which a variant was indicated, in which a combination of factors allows to achieve the highest punctuality of order fulfillment, the smallest size of the warehouse and the optimal load of workstations (the shortest inactivity, the longest implementation of the production process).
