Method for scheduling a production process

摘要

The invention is related to a method for scheduling a production process within a production system (10), the system comprising a calculation unit (12) for performing the steps of the method at least in part, production means (14, 16, 18, 20, 24, 26) with the capability to get the physical production process behind them optimized either concerning a decreased production time (62) or an increased efficiency (64) and electrical energy supply means (28, 30, 32, 34) for supplying at least the production means (14, 16, 18, 20, 24, 26) with electrical energy, wherein the availability (82, 102, 132) of the energy supply means (28, 30, 32, 34) might differ (84, 104, 134) in short-term from a respective long-term schedule. The method is characterized by the following steps: continuously providing a characteristic value (42) for describing the actual availability (48), the expected forthcoming short-term availability (52) and at least in part the scheduled long-term availability (50) of the energy supply means (28, 30, 32, 34) to the calculation unit, in case of an unscheduled forthcoming (a) reduction, or (b) increase in short-term availability of the energy supply means: optimizing at least one of the production means (14, 16, 18, 20, 24, 26) concerning a decreased production time instead of optimizing concerning increased efficiency, so that a timespan (110, 114, 122) with reduced or without energy consumption from the at least one production means (14, 16, 18, 20, 24, 26) is obtained therewith, scheduling the production means (14, 16, 18, 20, 24, 26) in that way, that the time span (110, 114, 122) with reduced or without energy consumption prefer-ably takes place (a) in times of reduced energy supply means or (b) after times of increased availability of energy supply means.
