Flexible Production Scheduling with Volatile Energy Rates

The demand for electrical power in industrial production processes arises often in high energy costs for companies. In the future volatile energy rates, which are a consequence of the increasing power generation from renewable energies, can influence these energy costs. In order to reduce the energy costs with the help of volatile energy rates, latter have to be considered in the production scheduling. To date, only few planning approaches in the field of job-shop scheduling deal with volatile energy rates. A transfer into planning tasks of serial production as the economic lot scheduling problem is missing. This contribution introduces a planning approach for the energy-oriented lot sizing and scheduling problem.
