Abstract:The volume development in 2012 of the Ingredients group of FrieslandCampina was limited due to the maximum utilization of the production capacity. This also holds for Domo Borculo; the demand for (most of the) Domo products is higher than its current production.The complexity of the production process, the autonomy of the operators, and the uncertainty in the arrival of raw materials makes it difficult to control the production process. This research focusses on the lactose-rich products, since Domo Borculo encounters the most problems with this process. We developed a scheduling heuristic. The initial goal of scheduling is to provide Domo Borculo with control over the production system. The main goal of the heuristic is to maximize the utilization of the bottleneck. K1 is currently the bottleneck due to the long waiting times in the tanks. With the scheduling method, we can eliminate unnecessary waiting time and therefore we assume that the dissolving street is the bottleneck. From the main scheduling goal we derived a secondary goal: a minimum number of product switches at the bottleneck. We motivate our choice for the proposed heuristic by means of three case studies and an evaluation by experts.
