Abstract

A forging method is provided. The forging comprises determining plans of second and third processes for each of a plurality of ingots, categorizing the plurality of ingots into first and second ingot sets, based on the plans of the second and third processes, evaluating the first and second ingot sets using a scoring function, determining an ingot set to be provided to a first heating furnace, based on the evaluating of the first and second ingot sets, and performing a first process, different from the second and third processes, on the ingot set provided to the first heating furnace.

First claim

What is claimed is:

1. A forging method comprising:
determining plans of second and third processes for each of a plurality of ingots;
categorizing the plurality of ingots into first and second ingot sets, based on the plans of the second and third processes;
evaluating the first and second ingot sets using a scoring function;
determining an ingot set to be provided to a first heating furnace, based on the evaluating of the first and second ingot sets; and
performing a first process, different from the second and third processes, on the ingot set provided to the first heating furnace.

2. The forging method of claim 1 , wherein the first process comprises a heating process, the second process comprises one selected from among a forging process, a cutting process, and a heat treatment process, and the third process comprises one selected from among a forging process, a cutting process, and a heat treatment process, different from the second process.

3. The forging method of claim 1 , wherein the scoring function comprises products of first variables for the first and second ingot sets and a first weight for the first variables.

4. The forging method of claim 3 , wherein the evaluating of the first and second ingot sets comprises comparing the product of the first variable of the first ingot set and the first weight with the product of the first variable of the second ingot set and the first weight.

5. The forging method of claim 3 , wherein the first variables include a mass, a variance in mass distribution, a number of types of products manufactured, and an estimated consumption time.

6. The forging method of claim 3 , wherein the first weight is repeatedly updated by a generic algorithm.

7. A forging method comprising:
categorizing a plurality of ingots into first and second ingot sets;
evaluating the first and second ingot sets using a scoring function;
determining an ingot set to be provided to a first heating furnace, based on the evaluation on the first and second ingot sets; and
performing a first process on the ingot set provided to the first heating furnace,
wherein, when the ingot set to be provided to the first heating furnace is determined to be the first ingot set,
the second ingot set is recategorized into third and fourth ingot sets,
the third and fourth ingot sets are evaluated using the scoring function, and
an ingot set to be provided to a second heating furnace is determined, based on the evaluation on the third and fourth ingot sets, and
when the ingot set to be provided to the first heating furnace is determined to be the second ingot set,
the first ingot set is recategorized into third and fourth ingot sets,
the third and fourth ingot sets are evaluated using the scoring function, and
an ingot set to be provided to the second heating furnace is determined, based on the evaluation on the third and fourth ingot sets.
