Nowadays, customers are increasingly demanding more from products in terms of quality, flexibility, and delivery performance, while the price may hardly change due to many competitors. These requirements create a certain pressure on individual companies if they would like to hold their own in the competitive environment. Due to the constantly changing requirements, it is important for companies to identify certain potentials at an early stage and to adjust production accordingly. In the area of production, sequence planning is an important optimization tool that can be used for different objectives. It forms the foundation for detailed planning in companies and specifies the sequence of products to be processed. This paper deals with the topic of sequence planning in flow shop production. In the context of this, production planning and control are first discussed, as well as the areas of application of sequence planning. Subsequently, the basic models and the currently used methods are explained in more detail. To be able to give an outlook on future research directions in this area, an investigation of several current publications is carried out at the end. The knowledge gained from this work is intended to provide a quick overview of sequence planning and its application in flow shop production systems.
