Abstract

A method for an industrial system. The method includes: ascertaining a representation of the industrial system, the ascertainment of the representation including: selecting a first state of the representation, selecting, based on the first state, at least one machining order from a plurality of machining orders as a function of the first state of the representation and as a function of at least one previously ascertained recommendation, and ascertaining a second state as a subsequent state of the first state via a simulation of the second state as a function of the at least one selected machining order and as a function of the first state; and ascertaining a manufacturing schedule for the industrial system as a function of the ascertained representation.

First claim

What is claimed is:

1 . A method for an industrial system, comprising the following steps:
ascertaining a representation of industrial system, the ascertaining of the representation including:
selecting a first state of the representation,
selecting, based on the first state, at least one machining order from a plurality of machining orders as a function of the first state of the representation and as a function of at least one previously ascertained recommendation,
ascertaining a second state as a subsequent state of the first state via a simulation of the second state as a function of the at least one selected machining order and as a function of the first state; and
ascertaining a manufacturing schedule for the industrial system as a function of the ascertained representation.

2 . The method as recited in claim 1 , further comprising:
operating the industrial system as a function of the ascertained manufacturing schedule.

3 . The method as recited in claim 2 , further comprising:
ascertaining that an abort criterion for operating the industrial system is met; ascertaining a second representation having a state of the industrial system upon meeting the abort criterion as a start state of the second representation; ascertaining a second manufacturing schedule for the industrial system as a function of the ascertained second representation; and operating the industrial system as a function of the second manufacturing schedule.

4 . The method as recited in claim 1 , wherein the ascertaining of the representation of the industrial system further includes:
assigning the selected at least one machining order to a processing resource of the representation of the industrial system as a function of a state of the processing resource of the representation in the first state.

5 . The method as recited in claim 1 , wherein the ascertaining of the representation of the industrial system further includes:
returning a result of the simulation along with selected states.

6 . The method as recited in claim 1 , wherein the ascertaining of the representation of the industrial system further includes:
reducing a weighting of the previously ascertained recommendation when selecting the at least one machining order with an increasing number of simulations of a respective state of the representation.

7 . The method as recited in claim 1 , wherein the selecting of the machining order includes:
selecting the machining order from the plurality of machining orders as a function of the previously ascertained recommendation and as a function of a criterion, the criterion including at least one of the following criteria:
an increased number of carried out simulations;
an increased average total reward.

8 . The method as recited in claim 1 , wherein the ascertained first and second states of the representation are part of a Monte Carlo search tree.

9 . A device for an industrial system which is configured to:
ascertain a representation of the industrial system, the ascertainment of the representation including:
selection of a first state of the representation,
selection of, based on the first state, at least one machining order from a plurality of machining orders as a function of the first state of the representation and as a function of at least one previously ascertained recommendation,
ascertainment of a second state as a subsequent state of the first state via a simulation of the second state as a function of the at last one selected machining order and as a function of the first state; and
ascertain a manufacturing schedule for the industrial system as a function of the ascertained representation.

10 . The device as recited in claim 9 , wherein the device is further configured to operate the industrial system as a function of the ascertained manufacturing schedule.

11 . A method for an industrial system, the method comprising:
providing a device for the industrial system which is configured to:
ascertain a representation of the industrial system, the ascertainment of the representation including:
selection of a first state of the representation,
selection of, based on the first state, at least one machining order from a plurality of machining orders as a function of the first state of the representation and as a function of at least one previously ascertained recommendation,
ascertainment of a second state as a subsequent state of the first state via a simulation of the second state as a function of the at last one selected machining order and as a function of the first state; and

ascertain a manufacturing schedule for the industrial system as a function of the ascertained representation; and
using the device to ascertain the manufacturing schedule.
