Production companies are under increasing pressure to meet the demands and needs of their customers. They expect constant ability to deliver goods, with an increasingly changing assortment and a declining order volume for each item. With conventional planning methods the production is not able to respond and manage last minute orders, changes, bottlenecks or failures. Companies are required to improve processes in order to stay ahead of competitors. In the end, only the reliable and cheaper supplier wins, especially during bottlenecks. The optimization of production planning must be the top priority of any production company. FLS FertigungsLeitSysteme GmbH & Co. KG with its production planning software FEKOR offers a solution, which enables companies to optimize the utilization of the available resources and raise hidden potential.
