Abstract: Production scheduling is an important component of overall production planning in multipurpose plants. The production process of an existing multipurpose plant, manufacturing yoghurt and related products, was modelled using Visual SLAM$\sp{\rm TM}$ and AweSim$\sp{\rm TM}.$ A computer-optimized weekly and daily scheduling procedure was developed using Microsoft Excel scheduling tool. Actual plant production data was collected used to validate the process simulation model. The model and the scheduling tool were then applied to answer several key management questions. The results show that computer-optimized scheduling could save 6.6% of packaging cost and 9.7% of packaging hours. The model was also used to identify process bottlenecks and revealed that 11 to 32% savings could be realized by addition of a second blender. Finally the model and the scheduling tool were used to compare 5 and 6 day production schedules to meet high production demand.
