Method and system for adapting a production flow schedule for a production process

A production planning system for adapting a production flow schedule for one or more production processes, at least some of the one or more processes including process steps using energy for their execution, wherein the production planning system is configured:

• to identify at least one availability time window in which a predetermined minimum energy availability is present within a predetermined optimization period based on availability information that indicates a forecast energy availability during the optimization period;
• to indicate one or more flexible process steps, wherein the one or more flexible process steps specify those process steps that can be executed in one or more alternative time windows within the optimization period without impairing one or more optimization variables on which the preparation of the production flow schedule is based;
• and
• for each of the flexible process steps, to reschedule the appropriate flexible process step into one of the relevant alternative time windows if the rescheduling is within the availability time window in order to obtain an adapted production flow schedule.

A computer program product comprising a non-transitory computer readable medium having a computer readable code for adapting a production flow schedule for one or more production processes, at least some of the one or more processes including process steps that use energy for their execution, wherein the computer readable code will configure a computer to perform a method which includes:

• identifying at least one availability time window in which a predetermined minimum energy availability is present within a predetermined optimization period based on availability information that indicates a forecast energy availability during the optimization period;
• indicating one or more flexible process steps, wherein the one or more flexible process steps specify those process steps that can be executed in one or more alternative time windows within the optimization period without impairing one or more optimization variables on which the preparation of the production flow schedule is based;
• and
• for each of the flexible process steps, rescheduling the appropriate flexible process step into one of the relevant alternative time windows if the rescheduling is within the availability time window in order to obtain an adapted production flow schedule.
