Abstract:Johma Salades is a leading company in the salad manufacturing industry located in Losser, the Netherlands. Johma manufactures all kinds of salads for their brand as well as private labels. To stay competitive, Johma needs to make its production processes as efficient as possible. Johma’s main manufacturing department, Kitchen 1, which focuses on bread and toast salads, is not performing efficiently enough. The main reason for this is that the current production scheduling method is too basic or even non-existent in some elements. This causes the salad mixtures to be delivered too late, leading to idle times for the corresponding filling lines. In the previous two production years, Kitchen 1 was responsible for idle times at the filling lines, which accounted for almost 18% of the total production time. Therefore, the core problem identified is the lack of an optimal scheduling method for the jobs and operations in Kitchen 1. This research aims to develop a scheduling approach for Kitchen 1 by answering the following main research question: ’How can Johma near-optimally schedule the required jobs and operations to prepare and mix the salad mixtures in Kitchen 1 to meet the demand of the filling lines, decrease the idle time, and increase flow in the production facility?’
