En un mundo caracterizado por la constante interrupción en la cadena de suministro, la capacidad de analizar rápidamente diferentes escenarios se ha vuelto esencial. Ante preguntas cruciales como la detención de una línea de producción o el cierre de un centro de distribución, empresas líderes como Intel y La-Z-Boy están adoptando gemelos digitales de sus cadenas de suministro para una toma de decisiones ágil.
Desafíos y respuestas en la-z-boy
El fabricante de muebles estadounidense La-Z-Boy se encontró con desafíos significativos cuando la demanda de sillones y sofás aumentó abruptamente al inicio de la pandemia de COVID-19. Ante esta incertidumbre, La-Z-Boy recurrió a la tecnología, utilizando el software de modelado de cadenas de suministro de AIMMS para construir un modelo de su cadena existente. Aanan Panday, consultor de cadena de suministro de AIMMS, destaca que este primer paso es crucial para validar el modelo utilizando datos históricos y ganar confianza en el diseño.
El siguiente paso para La-Z-Boy fue explorar diversos escenarios hipotéticos. ¿Qué sucedería si aumentaran la capacidad de las fábricas existentes? ¿Y si abrieran una nueva planta de producción? Este análisis de escenarios proporcionó una visión clara del diseño óptimo de la cadena de suministro. Panday subraya que este proceso, aunque llevó meses, permitió a La-Z-Boy identificar con precisión las ubicaciones que necesitaban o no capacidad adicional, ahorrando así decenas de millones de euros en costos.
Gemelos digitales: de la modelización a la acción
La pandemia de COVID-19 intensificó la necesidad de modelar cadenas de suministro, ya que las interrupciones se volvieron más frecuentes e impredecibles. AIMMS destaca que el análisis de escenarios se ha convertido en una prioridad a medida que las empresas buscan adaptarse rápidamente a las nuevas perturbaciones, como la guerra en Ucrania. Panday señala que, una vez que se tiene un modelo sólido basado en datos actuales, conocido como «gemelo digital», ajustar parámetros y evaluar el impacto en tiempo real se vuelve más accesible. Esto permite realizar compensaciones efectivas entre costos, riesgos, disponibilidad de productos y sostenibilidad.
Cambio en la naturaleza de las preguntas
El modelado de la cadena de suministro ha evolucionado significativamente. Antes era un ejercicio anual centrado en preguntas estratégicas sobre ubicaciones óptimas de producción y distribución. Hoy en día, se utiliza para abordar cuestiones tácticas y operativas, como la cantidad de capacidad de fabricación e inventario necesaria en cada ubicación y la priorización de productos en el almacén.
Con herramientas avanzadas como las proporcionadas por AIMMS, el modelado de la cadena de suministro se ha simplificado. Aunque sigue requiriendo conocimientos de análisis de datos y operativos, AIMMS ha demostrado que puede proporcionar resultados en cuestión de meses, permitiendo a las empresas adaptarse rápidamente a las cambiantes dinámicas de la cadena de suministro.
Intel: Un Caso de Uso Adicional
El fabricante de chips Intel también optó por construir su propio equipo de modelado de cadena de suministro en respuesta a la necesidad de adaptarse a cierres de centros de distribución durante la pandemia. El gemelo digital resultante se ha vuelto inmensamente valioso para Intel al abordar desafíos como la escasez global de chips. Paul van Nierop, propietario de producto de AIMMS, destaca que el gemelo digital ha permitido a Intel analizar rápidamente diversos escenarios, como el reciente cierre en Shanghai, facilitando la toma proactiva de decisiones para la planificación de contingencias.

It s nine o clock in the evening, and the little guy needs enough Sleeping time, so Mrs.Aunt, this is not my brother. Li Shaoxi carefully protected his nephew in his arms, preventing Hua Zhiqing from snatching him away.
Don t be sad, it s not your fault. If she hadn t wanted to hit you with her body, this wouldn t have happened to her If this hadn t happened, perhaps, she would only have to sit there for ten or twenty years.I don t know You can get out Li Shaoting replied coldly.
Hearing these words, Ye Zixiu s heart instantly dropped.I didn t really want to kill him. Dead flower Zhiqing.
Master Ling, things over in country Z have already arrived.Mu Xinran squatted down, touched his head, and corrected It s godmother.
The strength in Li Shaoting s hand made her breathless, and even the suffocating feeling made her very painful.I didn t expect, I didn t expect that after not seeing each other for two years, I would hide here and open a coffee shop.
She looked at the time and saw that school had been out for fifteen minutes.Li Shaoting vs. Lu It s only a matter of time before the Clan takes action, and our Lu family has almost no chance to resist now.
Then he glanced at Bai Luo behind him and motioned for him to move another chair over.The little guy slapped his mommy excitedly, and then started sucking his little thumb again.
The doctor passing by said that Uncle Lin was doing surgery on someone else.However, Ye Zixiu didn t push you to others, it was you who pushed me away.
Since the Li family always likes to take away other people s things, then he should follow the example of the Li family and take away his aunt s son.The virgin Bai Luo on the side felt embarrassed to stay here.
There was an ominous premonition in my heart, but I felt relieved when I saw that there were a few pieces of clothing missing in the closet.If you want to give up halfway, then treat what I just said as nonsense.
got up. She glared at Li Shaoting angrily. She really didn t scare herself to death just now. I really thought that my male fans were so arrogant that they came to Li s house and even came to their room.He was as anxious as an ant on a hot pot. I went to look for it and found my aunt to call you.
After about half an hour, the teacher asked these students to practice dozens of times by themselves, and then came over.What hurt was his hand, but what hurt was his woman s heart.
He doesn t even know that something has fallen. As soon as the little guy walked in the door.Yi Zixiu, it s impossible, don t waste your time. The indifferent tone made Ye Zixiu feel suffocated in his chest.
How could she not know whether she was her own daughter Do they still need to tell him He walked in front of Ye Zixiu and looked at him sharply Yi Fei, I don t know what Feifei said to you, but what you said is too much.Li has another wife Lin Yan vividly expressed the man s gossip mentality.
Sorry, I have to go to class So Gu Ruoyi picked up the textbook and left the office as if running away.Don t be anxious. Take your time. Now that we know it s Mo Wanwan, I believe we can find out Mo Wanwan s whereabouts soon.
Why did you frame me Why did you frame me for pouring soapy water in the bathroom What was your intention Gu Ruoyi made an imperceptible arc.Mu Xinran panicked immediately. She knew they would take Xiao Min away from her, but seeing the tears and self blame on Xiao Chen s face, she tried her best to calm down and squeeze out a comfort.
His eyes were a little complicated. He turned his attention to Gu Ruoyi and said solemnly Mrs.Since you are all here and the children have been handed back to you, then I will go to Chen s side.
I figured out my purpose of coming here. Forget it, I won t argue with you, an ugly monster.Li, give me a daughter I have already thought of my daughter s name, she will be called Li Aiyi.
I believe that Uncle Li will be grateful to me after reading it Li Haotian read carefully, but when his eyes touched the 9.From the corner of her eye, she saw Lu Qianxue staring at him, as if he couldn t understand why she didn t have an accident on the stage Gu Ruoyi slowly walked towards her and raised a stunning smile Lu Qianxue, thanks to what you just said, my catwalk was quite successful I m looking forward to your next performance, but don t let anything happen to you.
So many things happened that she did not dare to face Li Shaoting.Bai Feifei, what are you doing here Gu Ruoyi asked angrily, cold fire bursting out of her eyes.
What, you re unhappy Gu Ruoyi saw his expression and asked unhappily.It was no longer easy for Mommy to raise him by herself.
The little guy lives in a ward and is cared for by specialized medical staff.He was sitting on the sofa, looking at a certain page of the business book in trance.
Ating and the old man have never recognized your identity, so you have been wronged in the Li family Li Haotian sighed twice, feeling melancholy.As he spoke, Li Shaoting raised the temperature of the water to forty degrees.
They built a lot of construction projects, led by the Confucian Temple, Zhongtu Divine Continent, Liuxia Continent, and Aai Aizhou, each of which contributed money and effort.
Like three nails, hammered into the landscape of the wild world. Over one of the ferries, nearly two hundred sword boats as big as mountains hovered all year round, blocking out the sky and the sun, all because of the failure of the great war.
Be more powerful. You can t be a mere mediocre person. He put his hands behind his back and nodded, No, Brother Cui told me to be more courageous when talking to others in the future.Cui Dongshan received a reminder from his husband and suddenly said loudly Sir, a girl named Qiangyue is now living in the blacksmith shop on the bank of Longxu River.
Otherwise It is a well deserved treasure of immortal weapons. It is so sharp that it can regard a piece of military nectar armor as a piece of paper.Bailu Zhenren, who was born with withered bones, ended up being smashed with mud by a group of naughty children in the countryside.
Jiang Shangzhen had previously given each of the four children a fasting jade tablet equivalent to a customs clearance document, which allowed them to visit Laojun Mountain.The current statements made by Li Huai and the old man had roughly the same meaning. As for the old man who struck fiercely and cruelly, crushing other people s backbones with one kick, Li Baoping had already guessed his identity.
Cheng Chaolu suddenly asked timidly I can learn from Master Cao Boxing I promise you won t delay sword practice Bai Xuan, who put his hands behind his back, rolled his eyes and muttered in a low voice What a puppy.When he climbed up, he was trapped in it. Unless he is a Nascent Soul like Lu Yong, even a Golden Alchemist would feel like he was in the clouds and could not see any scenery clearly.
He already looked like it had nothing to do with him. Mrs. Jiang of Yunlin is great, but she doesn t want him to beg for favors.Chen Ping an had already gently increased the strength on his feet, making the two adjacent houses stable and unaffected by the qi machine.
Chen Ping an originally wanted to twist out a few more talismans and post them on the windows and doors, but after thinking about it, he decided not to make the children too cautious.I think of this Yuhu Street person. The bottleneck sword cultivator of Longmen Realm inevitably thinks of the old and new five skills of the Great Wall of Sword Qi.
Cui Wei had no expression on his face and replied In the past, I was greedy for life and afraid of death.Anyway, he looked stupid. Pei Qian really thought that this kind of thing was impossible, and he didn t like her for anything, and she didn t look good.
Pei Qian s only impression of the Liu family in Aaizhou was that they were rich. Pei Qian experienced this firsthand when he traveled alone to the Daduan Dynasty.
Narcissus, Pei Min is definitely not easy to take action. Although the most lethal one is Pei Min s last broken sword, which is specially used to kill sword cultivators on the mountain, it is still the one that kills Narcissus the fewest times.Standing there was a young man with antlers with silver eyes. Most of them are important characters in major cities outside of Entry City.
Qidun Mountain is even the beiyue mountain lord Wei Bo. The place of prosperity , and the Embroidered River Water God, because of the relationship between the ghost of the married woman, and the Gu family of Mu Ping Lane and Chen Ping an, are not strangers, so there shouldn t be any surprises.Feijian wrote back and said that he had indeed found someone, but Jiang Shangzhen was kept in the dark.
When the ferry goes north, it will naturally pass by the river that enters the sea at the door of Jiang s house in Yunlin.Among them, Liu Qi in the Ascension Realm, because his poems are so well written and widely circulated, but why the Liu Jin Realm came and why there is an immortal destiny of ascending to the sky in one step, have not spread in the vast world, so Liu Qi is on the mountain, Peak, in particular, is known as one of the most underrated monks.
Even the benefits and advantages of sesame and mung bean size on Luolu Mountain, Chen Lingjun will not touch.So Feiran just used Haoran s popularity in the world to use a name to target Chen Pingan. Tongyezhou, all the restored dynasties that were jealous of Daquan, as well as within the Daquan Dynasty, both the government and the public, all the scholars who were dissatisfied with the Yao Empress, Haoran Jiuzhou, all the mountain monks in the world who were not too big to watch the excitement, and even Confucian disciples from the Yasheng lineage will contribute to the flames intentionally or unintentionally.
They were several high grade talismans recorded in the authentic alchemy book. One of them was called the Ferry Talisman , which could calm the mind.It s natural and natural. Yes, yes, what you said is exactly what you said. A single minded skill is horribly profound. It is even worse than the limit of a martial artist.
Bai would agree to this. He raised his head and was a little confused for a moment. Dong Huafu reminded No matter how big a seal is, how big can it be Fans will have more inscriptions.Chen Ping an sat on the small bamboo chair in the middle. Cui Dongshan crossed his legs and stared at the full moon in the sky with wide eyes.
Both his master and apprentice seemed to have fallen into the hands of this friend of Chen Pingan. Privately, Sun Qing would also complain about his disciple Liu Guibao, why did he like a playboy like Yu Mi It would be better to imitate his master.As for magic weapons, not to mention ordinary masters, even Shanze wild cultivators who are already cultivators may not be able to see them a few times in their lives.
Han Yushu was about to ask Jiang Shangzhen to let Han Jiangshu go. He frowned slightly and shifted his gaze. He saw the man in green shirt standing unscathed, holding a slightly swaying spark between his fingers and looking up at Han Yushu.However, even if you looked down from the ferry for a long time, there were still very few smoke in the world.
This is the plan of Jinding Temple, but today the guarding monk of Jinding Temple was lucky and did not hit Chen Pingan.Chen, you haven t seen that scene. That large group of powerless officials, if Xu Qingzhou hadn t stopped them at that time, I could have knocked them all to the ground by myself.
Unless you have the courage and strength to learn from Pei Qian and break through the restrictions of mountains and rivers.Chen Ping an walked slowly, walked to the long stone bench under a green pine outside the temple and sat down.
The monks of Tingyun Hall, the ancestors of the first three generations, are all very hard boned immortal masters.On Qingzhi Pai Mountain, there was actually a game of chess in the pavilion today. It was a game of chess between two fairies, but the distance was not close.
It s just a pity that I lost my share of Wanyao Sect s ancestral heritage. In this case, we can only find another way to start our own business.Chen Ping an was short of money at that time and only bought a book of mountains and seas. He was not willing to buy a supplementary book that was larger and recorded more complicated and detailed records of mountains and rivers.
As expected, he is from the Genealogy Immortal Master. It is probably because of the incense and love accumulated in the Ancestral Master Hall that he was able to get an enshrinement in Yunku Blessed Land and Jade Guizong Jiuyifeng.This ferry stops at the Xianjia Ferry at the southernmost tip of Tongye Continent, which is not too far from Jade Guizong.
It s just that the price of such a careful calculation is that Qi Jingchun s mind and Taoism have to be consumed all the time, in exchange for Cui Chan using an incredible shortcut to reach the Fourteenth Realm, not only relying on Qi Jingchun s knowledge of the Tao, but also stealing Zhou Mi s books.
Du Hanling was also willing to spend money to let Lu Ying I caught a very important chief offering. Lu Ying was determined to run around for Jinding Temple.I don t need to get your book, it s written in the book What, I knew it by heart more than 20 years ago.
Putting on the posture of quarreling with others, he can beat the snake seven inches away, and one or two soft words that seem to be light can make people afraid.The idea is tough and very tricky, so be careful. I just moved out two uncles in one breath, One of the most proud people in the world has not been able to scare him.
Among the six yamen that accompany the capital, except for the minister, who still chooses a steady old man, the other ministers are all young officials like Yuan Zhengding.Chen Pingan said helplessly That s about it, Pei. Qian doesn t like this. Jiang Shangzhen still thought to himself and said, But having said that, Pei Qian has the best vision.
It comes from the fact that every moonlit night, the ancient ink will appear on it. There was a little Taoist who was walking like a fly and asked him.The person he was really afraid of was not Ma Kuxuan, but Yu Shiwei who had made up his mind to sit on the sidelines.
Be serious, don t do unnecessary actions.Song Tingfeng warned with a frown.His sleeping wife suddenly heard a scream and went out to check.
The news came over again and again, and if it was not resolved, it always felt like a hidden danger.After a long time, a red light suddenly rose in the eastern sky, lasted for a few seconds, and then dissipated.
Second Uncle Xu left the house at dawn and gathered his sword guards.Xu Qi an soaked in the hot water full of petals, and exhaled comfortably.
Zhang Yuying was crying Hugging her mother in her arms, she cried, It was the son of Zhou Shilang who kidnapped me.But Emperor Yuan Jing, who had already practiced abstinence at that time, didn t touch her with a single finger.
Accidentally conceived a cub, another big expense.And my current salary is only enough to support a regular wife, and I can t afford the boring life of rich people hugging each other.I heard the old saying that my aunt stayed up all night because of me.
The princes agreed, and the princesses smiled subtly.Even if you cross time, you will be severely beaten by society.
Li Yuchun said Buddhist sect leads the countries in the Western Regions, and is powerful.Zhu Guangxiao didn t understand, Song Tingfeng was stunned for two seconds, and cursed Grandma, you are such a second person.
Seeing that No.5 finished his speech, Xu Qi an took a few words and began to share his knowledge of the Sangbo case The thing sealed under Sangbo may be related to the monster race.Such a great talent, to be a fast hand in the Changle County Yamen is too condescending, even if he can only write poetry, it is enough for the palace to be raised in the house, and the princess thinks in her heart as a chief of staff.
In Dafeng, no one is willing to offend Jianzheng.Even Yunlu Academy, which claims to be orthodox Confucianism, was ridiculed by the drinking loving Jianzheng for disobeying the law, but he held his nose and admitted it.Yes Everyone said in unison.Because they are all silver and copper gongs under Yang Yan s hands, everyone is still obedient, but they are a little unconvinced.
Xu Qi an, who never went to Goulan to listen to music, nodded, expressing that he was not that kind of person.Sparse shadows and slanting water, clear and shallow water, dark fragrance floating moon dusk Wonderful, wonderful.
One is a powerful minister who supervises all officials, but he always wears Tsing Yi.Heaven and Earth One Sword The person who chose this name was either a middle school student or a paranoid Xu Qi an made a judgment in his heart, opened the thin book, and opened the preface There is nothing in the world that cannot be cut with a single knife.
The warlocks of the Sitianjian are very noble.Why don t I think that you haven t seen the expressions on their faces when they look at me in reverence.The water surface in Sangbo is clean, nothing is there, who would have thought that a grand ancestor worship ceremony was held here a few days ago.
The door of the master bedroom was pushed open, and a servant girl came in, stood in the hall, and said crisply My lady, the guest surnamed Yang outside was sent by the servant girl.Is it too arrogant to want to pick up the prisoner without a handwritten letter Is it too arrogant to give you three points outside This is a government office after all.
For a long time no one spoke.I don t know how long it took before a student burst into tears and his lips trembled When this poem comes out, everyone who chanted plums through the ages will be ashamed.As a criminal, Xu Pingzhi was the first to be investigated, tortured, his interpersonal relationship and financial situation, etc.
When you first came to Jiaofang Division, you can see her dancing.Isn t it a magic stick Xu Qi an said You also chose the other seven members of the Tiandihui just like me Yes Can I ask why The old Taoist laughed for the first time Yes, just listen After hearing what Pindao said next, the benefactor has no way out.
But seeing Si Tianjian s white clothes all over the courtyard, Mr.Seeing the moment when the eldest brother rescued the younger sister, Xu Lingyue felt that the image of the eldest brother was enough to be equal to the second brother.
6.No. 2 is warm hearted, at least on the surface.No.He was the protagonist of this farewell.Yang Gong, courtesy name Ziqian, nicknamed Ziyangjushi, was the No.
Xu Qi an didn t accept this truth.Although I have not been a policeman for many years, the three views established at that time are still alive.Xu Qi an didn t escape, and went straight to Young Master Jinyi, and in the face of the other party s terrified face, grabbed his neck and punched him hard in the lower abdomen.
Even saints can t live forever Well, I can t make a hasty conclusion, after all, I know too little information.He condensed his energy into his fists, lowered his waist, and hung down on the ground through the air.
Two Are you saying that you didn t say it Number four has friendship with the female national teacher Jinlian The Taoist priest is not lying, and the holders of the book from the ground are not ordinary people.Get dressed and go to my second uncle s house for breakfast.
However, although the blood is far away, the relationship is very close, because the Zhang family often sends benefits to that distant relative.I will test the tone and see what is going on.County magistrate Zhu thought to himself with.
I hope to see you reading the newspapers are long and lasting.Wei Yuan left the Golden Luan Hall, replaying the current situation in the court in his mind.
A carefree person. Gu Ruoyi looked at her suspiciously.Brother, how are you doing here Seeing the prison uniform on his body, she felt extremely dazzling.
I heard that you went to find her A calm voice came from above.Hey, he still wanted her to leave Li s house. He was really wishful thinking.
This was the love bento specially made for him by Mommy, so he was naturally very happy.Dinner was not very pleasant, it could be said to be dull.
The little guy was pulled by an office worker dressed as a thin man.Does my grandpa look okay Did Li Shaoting s people do anything to him Gu Ruoyi asked worriedly.
Nothing has happened yet, but my people have eavesdropped that Li Shaoting is forcing your grandfather to transfer Gu s shares.She saw Huangfu Ling s dark face, with a dangerous aura, and a little anger in his eyes.
What surprised him even more was Gu Ruoyi s answer If you don t see me, mommy will ask daddy to give you his.What, the young master is missing After being stunned for a long time, he hurriedly went to the side to make a phone call.
Pfft Ah Qing laughed out loud without knowing whether to live or die.Gu Ruoyi looked at the caller ID, gave Tony another look that said, Can t you see and pressed the answer button.
Who is Li Shaoting, who needs to disguise his emotions to make a woman relax her guard Gu Ruoyi looked at the woman over there, How many months is it, sister in law Exactly eight months Gu Chenxi flashed her head and said gently.Then she shook hard and twisted her body. He scratched his sore wrist and looked at Ye Zixiu aggrievedly Why are you so crazy with me I just went to find her.
After she got rid of the ants, I took it directly It s in hand.Otherwise, why would he have killed Li Shaoting a few months ago The man turned around leisurely, his handsome face looking normal, holding a cigar between his fingers, Mr.
Only now did she realize that thankless work could be so uncomfortable.He only knew that Mommy s answer was that she still liked Daddy.
stand up. Even if they didn t say anything, Li Shaoxi still knew their purpose of following him.She inquired yesterday and found out that Li Shaoting had already started asking people to manage their Gu family This is preparing to capture their Gu family Since he loves to disguise himself so much, why can t she, Gu Ruoyi, act with him Sir, I don t understand what you are talking about.
Cigarettes on the bed There is a smell of smoke in here, let s get out first.Have you eaten If not, can I ask the housekeeper to cook you a dinner No, Grandpa Li.
Of course it s Li Shaoting s house A low and playful voice came from behind.Li chatting with Are you so happy His tone was full of displeasure.
I won t eat you even if I bite you. With this tone, he knew , she remembered Li Shaoting looked at the woman on the hospital bed lovingly and smiled knowingly.Did you see it I was curious, so Gu Ruoyi blushed. She still watches action movies like this.
In the eyes of others, I felt pity for you Don t worry, Miss Lu, please don t worry, I have already done this for you.These things almost drove her crazy. Xinran, this is not your fault.
7. Judging from the results, Bai Feifei and Li Haotian are not father and daughter at all.She has a husband who loves her, two children who love her so much, and even other people are very kind to her.
Xiao Chen s mommy. Xiao Chen s mommy Mu Xinran was shocked.The smell of other women s perfume still lingered on him the next morning.
When did she go abroad for further study Yes, I heard what you from the Li family said.Yes, when did she prepare the child to take off his shoes But when I saw him yesterday, I went to a nearby supermarket to buy it when I came back.
These people must be Li Shaoting s people Gu Ruoyi clenched her fist tightly, feeling very hateful in her heart I hate it I hate the ruthlessness of this man Li Shaoting No, I m going to find Li Shaoting now.Anyway, Li Shaoting was here today, she She definitely couldn t leave.
If he really took Li Shaoxi away just now, I m afraid they would be the losers.Your great grandfather and your great grandfather both love you.
Gu Ruoyi comforted her. Hearing this, Mu Xinran nodded.Is this the plan to let Bai Feifei walk out of Li s house naked Wouldn t it be too inhumane Li Shaoting slowly raised his eyes and looked at Gu Ruoyi, What Are you soft hearted Seeing that she stood here for a long time, he asked first if she had any intention of talking to him.
These are what he saw in parenting books. Mrs. Li, let me hold the baby. Go take a shower.Xiao Min pursed his lips and blamed himself I m sorry, Xiao Chen, for making you worry.
