| Abstract: | This thesis contains a simulation study of the processes in printing company. The factory consists of 3 industrial printers and multiple finishing operations. The product portfolio includes amongst others: books, user manuals, leaflets, business cards, carton packaging, menu cards, posters and advertisement folders. The objective of this research is the following: Develop a suitable model to evaluate effects of increasing capacity and/or changing priority rules on production KPIs (tardiness, work-in-process, overtime) for a printing company with a process oriented layout subject to a variable demand. To find effects of changes to the production plant a simulation model is created. This simulation model consists of all the machines on the production floor. Data for the model is acquired from the app that records the action by the printers. Multiple simulation experiments were carried out to investigate the impact of the priority rules and the capacity. Out of all priority rules that were tested, the earliest due date (EDD) rule works best. To reduce overtime capacity can be added. It was found that adding extra machines does not decrease the average tardiness, however this can reduce overtime. |
