The industry in Germany is in the midst of the fourth industrial revolution. Customer requirements become more individual, batch sizes in production smaller. Custom tailored products in ͏»lot size 1« are becoming more and more the rule.
For this purpose, production must be able to react quickly to changing requirements. Orders are planned dynamically. For example, information on resource availability or deadline priorities is taken into account. In modern production facilities this task is taken over by the Manufacturing Execution System (MES).
The basis for production planning by means of an MES are statistical reference values. Frequently used values are production times, set-up times as well as tool requirements. For the recording of these values, a far-reaching digitalization is a prerequisite, which is often lacking in small and medium-sized enterprises (SMEs).
However, at lot size 1, there are no reference values. There is a lack of a reliable database for production planning. An individual, flexible production cannot succeed in this way.
