09 bước áp Dụng OEE Trong Quản Lý Sản Xuất thực phẩm
Trong ngành chế biến thực phẩm, việc áp dụng OEE (Overall Equipment Effectiveness) có thể là một cách hiệu quả để cải thiện hiệu suất tổng thể của dây chuyền sản xuất. Dưới đây là một ví dụ về cách một nhà máy chế biến thực phẩm áp dụng OEE để tối ưu hóa quá trình sản xuất của họ:
Bước 1:Xác Định Mục Tiêu
Để đạt được hiệu suất tối đa với OEE, điều quan trọng là xác định rõ mục tiêu của doanh nghiệp và sắp xếp ưu tiên để biết nơi cần tập trung. Hãy tiến hành một cuộc khảo sát và tính toán tiềm năng OEE thực tế của doanh nghiệp, bao gồm kế hoạch, tình trạng nguồn lực và thực trạng hiện tại của hoạt động sản xuất.
Nếu mục tiêu cuối cùng của doanh nghiệp là đạt đến mức OEE lý tưởng là 85%, nhưng OEE hiện tại của bạn chỉ là 50%, việc đạt được mục tiêu đó có thể sẽ khá khó khăn. Thay vào đó, hãy xác định một mục tiêu có thể đạt được và không ngừng nâng cao để tiến gần đến tiêu chuẩn OEE hàng đầu thế giới.
Trong ngành thực phẩm, tiêu chuẩn OEE có thể biến đổi lớn, dao động từ 30% – 70%, tùy thuộc vào nguồn lực, công ty, và các yếu tố khác.
Bước 2: Thu Thập Dữ Liệu Nhà Máy
Thu thập dữ liệu là một phần quan trọng trong quá trình triển khai áp dụng OEE. Lịch sử vận hành thiết bị và báo cáo sản xuất có thể mang lại một số thông tin hữu ích, nhưng nếu chỉ dựa vào những dữ liệu này, chúng ta không thể hiểu rõ hoàn toàn về tình hình sản xuất theo thời gian thực của doanh nghiệp.
Thay vào đó, sử dụng hệ thống theo dõi để ghi lại thông tin về thời gian hoạt động của thiết bị, thời gian dừng máy, sản lượng thực tế và số lượng sản phẩm bị lỗi hàng ngày theo thời gian thực là chìa khóa để triển khai thực thi OEE thành công. Các giải pháp phần mềm quản lý sản xuất MES tích hợp với các cảm biến trên IoT (Internet of Things) hiện đại sẽ giúp doanh nghiệp thu thập thông tin OEE một cách chính xác và kịp thời.
Ví dụ: thông qua việc sử dụng các cảm biến trên IoT, bạn có thể theo dõi trực tiếp và nhận biết những sự cố xảy ra trên dây chuyền sản xuất của mình ngay lập tức và liên tục. Điều này giúp bạn phát hiện và xử lý các vấn đề kịp thời, đảm bảo hoạt động sản xuất luôn diễn ra một cách hiệu quả và không bị gián đoạn.
Bước 3: Phân Tích và Xác Định Các Thành Phần Của OEE
Sau khi thu thập dữ liệu, nhóm phân tích tính toán các thành phần của OEE bao gồm Sẵn Sàng, Hiệu Suất, và Chất Lượng. Kết quả các thông số của OEE nên được trực quan hóa thành các biểu đồ, báo cáo cụ thể.
Ví dụ:mức độ sẵn sàng A đạt 80%, Hiệu suất P đạt 75%, và Chất lượng Q đạt 90%. Một cách để diễn giải ý nghĩa của biểu đồ OEE của nhà máy thực phẩm này có thể mô tả như sau:
Avaiability = 80%: nguồn lực về mặt thời gian được tận dụng 80% và 20% còn lại là khoảng thời gian chết
Quality = 90%: trong 100 sản phẩm thì chỉ có 90 sản phẩm được chứng nhận loại A về chất lượng, hoặc cứ 100 tiếng được dùng để sản xuất thì 10 tiếng là lãng phí do các vấn đề về chất lượng.
Performance = 75%: chỉ ra rằng tốc độ sản xuất của nhà máy kém hơn mục tiêu 25% về mặt thời gian.
Bước 4:Tính Toán OEE dựa trên các thành phần đã xác định
Doanh nghiệp phải cân nhắc lựa chọn phương pháp tính OEE (tính toán chi tiết dựa trên AQP hoặc đơn giản dựa trên hiệu quả) phù hợp với các đặc thù sản xuất của mình. Đồng thời, việc phát triển các chỉ số OEE cụ thể phải dựa trên mục tiêu giá trị cụ thể mà công ty muốn đạt được. Mặc dù phương pháp tính chỉ số OEE theo hiệu quả đơn giản hơn phương pháp tính OEE theo AQP, nhưng nó không thể thể hiện được mức độ hữu dụng và chất lượng sản phẩm.
Ví dụ:sử dụng công thức tính theo AQP OEE = Sẵn Sàng * Hiệu Suất * Chất Lượng để tính toán hiệu suất tổng thể của thiết bị thì OEE = 80% * 75% * 90% = 54%.
Bước 5:Xác định các vấn đề gây giảm sút OEE để cải tiến
Sau khi có cái nhìn tổng thể về tình trạng OEE tại đơn vị sản xuất, doanh nghiệp cần tiến hành xác định nguyên nhân gây ra các tổn thất OEE mà mình gặp phải. Chỉ số OEE thấp có thể do nhiều nguyên nhân gây ra, và mức độ tác động của từng nguyên nhân đến OEE có thể khác nhau. Trong quá trình tính toán các “tỷ lệ APQ, doanh nghiệp sẽ tìm thấy các loại tổn thất tương ứng được phản ánh thông qua đó.
Hơn nữa, chúng ta cũng có thể kết hợp sử dụng các phương pháp phân tích PM (P-M Analysis), phân tích nguyên nhân gốc rễ (Root cause analysis – RCA) để phân tích nguyên nhân khiến OEE bị thấp.
Việc xác định nguyên nhân gây tổn thất OEE thường yêu cầu tìm hiểu sâu về dữ liệu sản xuất của doanh nghiệp. Các phân tích nâng cao được cung cấp bởi phần mềm quản lý sản xuất MES hàng đầu sẽ giúp việc này trở nên dễ dàng hơn đáng kể.
Ví dụ:khi máy móc của bạn không thể tạo ra chất lượng như mong đợi, hãy tìm ra vấn đề. Đối với tình huống này, tổ chức cần kiểm tra xem có vấn đề gì với thiết bị, lỗi trong kho, nhận hàng và quản lý nhà cung cấp hay không.
Bước 6: Lên Kế Hoạch và Triển Khai Các biện pháp cải tiến
Dựa trên kết quả đánh giá, doanh nghiệp sẽ đề xuất các biện pháp cải tiến phù hợp và triển khai chúng để giảm thiểu sự cố kỹ thuật và tối ưu hóa quy trình chuyển đổi lô sản phẩm.
Bước 7: Theo Dõi và Đánh Giá Theo dõi OEE hàng ngày và đánh giá sự cải thiện.
Nhà máy liên tục theo dõi xem OEE theo thời gian thực đã tăng lên gần mục tiêu đặt ra hay chưa và tiếp tục cải tiến để đạt được mục tiêu đề ra.
Ví dụ:từ 50% ban đầu tiến hành cải tiến theo dõi đến khi đạt mục tiêu đề ra là 80%
Bước 8: Điều Chỉnh và Tối Ưu Hóa
Dựa trên dữ liệu theo dõi và đánh giá, doanh nghiệp sẽ tiến hành điều chỉnh kế hoạch, thay đổi các phương án cải tiến và tiến hành các biện pháp tối ưu hóa để đạt được hiệu suất tốt nhất.
Bước 9: Duy Trì và Phát Triển
Doanh nghiệp trì quy trình OEE và tiếp tục phát triển để đảm bảo rằng hiệu suất sản xuất luôn ổn định và tiến bộ.
Kết luận
Qua ví dụ trên, ta thấy rằng việc áp dụng OEE trong quản lý sản xuất thực phẩm không chỉ là một cách hiệu quả để đo lường và cải thiện hiệu suất tổng thể, mà còn là một quy trình có tổ chức và hệ thống giúp nhà máy tối ưu hóa quy trình sản xuất và đạt được mục tiêu sản xuất một cách hiệu quả và bền vững.
The woman called Sister Qing frowned slightly, looked at Xu Qi an, and said, Why did you attack someone It seemed that Xu Qi an was about to explain because of this woman, who knew The man in black robe spoke first.But for him, once Chai Xian s benefactor is sent back to the Western Regions, he will completely lose this vital dragon energy.
Go Luo Yuheng threw out the iron sword.The iron sword turned into a stream of light, went up against the sky, and hit the Arhat in love in an instant.On the other hand, Buddhism, after the Battle of Shanhaiguan, is like burning oil.
Even if he planned this drama, so what, with our combat power, it is enough to deal with it.This is.He stared at the old monk s palm, deliberating and testing.
Tables and chairs and other furnishings were placed in a complete manner, with no signs of battle.I want more.Desire personality Xu Qi an s heart moved, and he had a vague guess.
This punch hit its peak and was wonderful.Xu Qi an nodded slightly to express his appreciation, then stretched out his arms to wrap his arms around his neck, and threw him to the ground hard.She is as beautiful as she is beautiful, but her temperament and demeanor are even better, like a fairy lady on a picture scroll.
In the inn.A dark golden exquisite pagoda is placed on the table.Xu Qi an didn t think about it, and activated the qi in the dantian, and poured the qi left after passing through the magic nail into the Taiping knife.
Somewhere far away from the location of the Demon Slaughtering Conference, a huge pagoda stood in the air.Yo, you re back Liu Hongmian looked at her in surprise, and said with a smile, Xu Yuanhuai said that your mysterious person took away, but everyone is in a hurry.
Li Lingsu didn t think too much, and continued But that guy is very sensitive.This is an exception.Under normal circumstances, only a woman like Mrs.
Wang Simu said quietly If you agree to go out, if you go back, let the eldest brother go to Xu s mansion to talk about it.The old monk Taling was taken aback for a moment, quite pleased What did you realize Xu Qi an s face was neither happy nor sad Form is emptiness.
If the real culprit behind the scenes wanted to kill Chai Xian, he only needed to commit a murder somewhere to lure the snake out of the hole Unlock Your Wellness Potential: A Deep Dive into Hero ACV Gummies and catch Chai Xian.In half a decade, there will be ice ridges under the eaves.
This winter is extremely cold, the eldest princess sympathizes with Xu Unlock Rapid Weight Loss: The Science Behind the 15-Pound Transformation with Bariatric Seeds Xinian, a concubine of the Hanlin Academy, and specially orders someone to send thirty catties of animal gold charcoal for the imperial use.The reincarnated god held a silver ingot in his hand, and sometimes threw it to the left, sometimes to the right.
Anyway, she and Chu Yuanzhen had come to Sitianjian several times, so they were no strangers.The thought of going down suddenly surged like a thunderbolt.
Even if it is forcing Wang Yang Qian to make illusions Xu Qi an has never seen what he looks like.After The Buzz Around Oprah: Exploring the Rise of Keto Gummies and the "Oprah Effect" the belt was thrown out, something happened in the bed, and it began to struggle violently, and then calmly, a pair of silk pants were thrown out.
Xu is as good as Xu Qian.The Holy Son groaned in his heart.Therefore, she has a motive for committing the crime.
Luo Yuheng waved his hand, manipulating the Arhat to land in a corner, then took off his small shoes embroidered with cloud patterns, and sat cross legged on the bed.Fortunately, only one overlapped.This result is still in line with expectations.
Xu Lingyue nodded obediently Did that mother treat grandma like this back then Aunt curled her lips Did you forget Your grandmother passed away before I married your father.This is due to the prohibition of the magic weapon itself and the suppression of the teacher s formation.
Miao Youfang was distraught with shame and indignation.Yuan Yi, the commander of the capital, said calmly.
In this generation, there are only the Holy Son and the Holy Daughter.The fourth rank spy said It doesn t matter how long it takes, we just need to find the Dragon Qi host before that person.
Miss Ziyuan pursed her red lips, disappointment flashed in her eyes, and said softly, Young master, I will leave tomorrow, okay Miao Youfang corrected for a while, showing embarrassment, as a person with little experience, he couldn t say words to deceive women without blushing.Li Lingsu shook her head regretfully.Mu Nanzhi paced back and forth in the room, frowning tightly.
Wang kept shouting from the side Slow down, walk slowly.Commander Yuan Yi pondered So, she is looking for Nalan Tianlu now Liu Yun whispered Why didn t she leave the dreamland already.
Meng Jingzhe nodded vigorously.In fact, he really wanted to tell Axi that he didn t have to take his own affairs to heart.The shadow of the site and its companions have already arrived.
Heart Gu Master Chunyan saw that the leader of the Gu tribe had not spoken for a long time, so she had no choice but to speak, showing an attitude of active participation, and asked Then how do we let the heavens and the earth make up for Xu Qi an.He faintly understood that he had some understanding, but he couldn t fully grasp it.
I have a lot of blood in my heart.If you draw blood like this, I m afraid you will be the first to die.Meng Jingzhe tried to meet a beam of sword light, but after a while, he flew backwards.
Follow me.Meng Jingzhe brought the Dragon Yin Sword to the statue.But such a thing, how can it be so easy to explain clearly.
If you look carefully, you can see the white vines wrapped around the trunk.Seeing that Meng Jingzhe s face is not good, Qishan Xianzun added Don t worry, as long as your master calms down, I will be sure to cure his obsession.
The man s old face was full of ravines, his face was still ferocious, although the sword was fierce, there was room for concealment in the ferocity.And Meng Jingzhe seemed to know his inner thoughts, so he seemed extremely reckless, and would force his heart out every now and then.
Although Meng Jingzhe is not in good condition at this time, Sixi s body is not too bad.From Li Fengfan s yin and yang value 1 Li Fengfan choked up when he heard the words, he knew that his master had a high level Unlock Your Metabolism: 5 Natural Supplements for Fat Burning of cultivation, but he didn t expect everything he did , all under the nose of the other party.
It s impossible.As soon as he finished speaking, the soul locking lamp split open inch by inch.Axi s crisp voice sounded from behind.Uncle Shi didn t feel embarrassed when she heard her asking this question, but asked You don t want to stay in your own bedroom, and you go to play again His tone was very aggressive, and his words were full of hatred.
Volume has become the mainstream of contemporary society.Pixiu smiled and said I know that too.Then you. Meng Jingzhe couldn t understand now.This chess game is difficult to solve, and there is an hourglass next to it for timing, so it is almost impossible to make mistakes in one step when calculating.
As the old saying goes, there are only wrong names, not nicknames.Sighing, he withdrew the air machine and held the shark bead.
The honorable military general and the scholars present had great opinions, but they did not dare to openly disobey this respected senior scholar.If she leaves the shrine, she will associate with the demons.
What she meant was that she wanted to go to the border of the Western Regions to see what happened.Blood Sacrifice He waved his arms, and said in a deep voice, The power of all beings A stream of invisible and substanceless streams came from all directions, pouring into his body like a sea of rivers.
Meng Jingzhe was focused on fighting, so she didn t pay too much attention to the sudden news released by the system.So on the surface Erlang is a scholar with integrity, integrity and shame, but secretly he is very sneaky, for example, when Jiao Fangsi stays at the oiran at night, he doesn t even frown when he returns home.
The Emperor s New Clothes.Everyone pretended to understand, but in fact, they didn t make any progress because of listening to the lecture once.You can also try it yourself, he still has a lot of Unlock the Potential of Keto: A Deep Dive into Assure Medical Keto Gummies materials here Ye Shenglan suggested.
The girl immediately turned pale.A Boost Your Weight Loss: Simple Apple Cider Vinegar Strategies for Busy Professionals Xi, you dead girl who has no parents and no mother, don t talk nonsense Immediately there was a girl s flower protector scolded.Xu Qi an laughed.Nine tailed fox squinted his eyes, and urged You go, you go Xu Qi an briefly told her about her own condition, focusing on the grains imprinted in her genes, and said, What do you think Nine tailed fox examined Looking at him, surprise flashed in her long, narrow and charming eyes Have you become a god What she meant was that this only happened to gods and demons and their descendants.
Meng Jingzhe nodded slightly.When the young man saw the sword following Meng Jingzhe, his eyes suddenly fluctuated.You can t stop me anymore.Sixi said with a smile, his face became paler and his voice became more ethereal.
As he walked to the office, he dialed Wei Kaida s phone number.It didn t matter whether it was hard work or not, and Du Heng didn t care at all.
In the free afternoon outpatient clinic, Li Jianwei asked the two attending doctors to attend the clinic once a week, which was regarded as a subsidy for Nourishing Your Journey: 5 Delicious Mounjaro-Friendly Recipes for 2025 the two attending doctors.It s just the normal hospitalization fee.
Du Heng laughed, Is there such a good thing He picked up the red envelope and felt it.
That started from That s fundamentally wrong. Du Heng sighed, One more thing, Western medicine treats diseases by destroying the bacteria and viruses themselves, while Chinese medicine treats diseases by improving the place where bacteria and viruses survive, making this place unsuitable for bacteria and viruses to survive.
I didn t expect such a thing to happen. I m really sorry.The second one was even more horrifying, the half scream that made her liver tremble involuntarily.
We can rent it with the village. And if it can be done, the Security Bureau promises that the Bureau will cover one third of the cost.I treated it as lung heat and internal heat, and there was no problem.
Of course, this is not because of our relationship, but because of my consideration for the development of Zhonghu.Du Bing Unlock Your Weight Loss Potential: The Best Green Teas in Sydney s wife is not a cheap person. In our village, from ninety nine to eighteen nine, who has she not fucked with After all, I think this matter is definitely not over yet.
Moreover, the person who was queuing with him just now somehow ran into the queue at the 2nd Clinic.He assisted Wu Buwei beside him. After all, a good doctor cannot be judged by listening alone.
He didn t expect that this young man was really capable.I just did it because of the leader s request. Moreover, I am a doctor, and it is my duty to treat patients, so there is no need to feel depressed and uncomfortable.
Seeing the collapsed appearance of the people surrounded, they were very satisfied.Standing next to Du Heng, he Instant Relief: Exploring Natural Ways to Lower Blood Pressure Quickly said softly, After investigation, the woman just now is the sister in law of the canteen contractor.
Wang Shiyuan s wife I haven t eaten dinner, so my stomach is growling now.When I opened my eyes in the morning, everything felt like it was spinning in circles, even the roof.
He always felt that this guy might be used to being a leader now, and the questions he asked were all nice nonsense.We have few people and cannot be transferred, so we can Warm Up Your Winter Wellness: Herbal Teas for a Gentle New Year only I ll take it.
When you ask, he will say that his brain hurts. Dean Du, you don t know how bad I was at that time.When I was called to the Human Resources Department in the afternoon to pick up people, I was also confused.
The longer the time, the greater the chance of being damaged.They all knew that Du Heng had several banners in his cabinet.
Not all of them are useless idiots on my side. However, the doctor s quick answer made the Chinese medicine students and doctors watching behind him no longer remain Unlock Your Best Self: The Keto Gummies Revolution Transforming Weight Loss in Australia silent.I remember that there was an abnormal death. The public security organ will open a case for investigation.
The first thought in their minds was, could this man named Du Heng come to poison his mother Du Heng said nothing, he was waiting for the decision from the two opposite parties.yin and yang inside and outside. If you can t distinguish clearly, mistake heat for cold, and use the wrong medicine, everything will be lost.
Instead, he had chronic persistent mixed hepatitis A and B twenty years ago.gone. Just at this time, Du Bing also walked by carrying boiled water.
He glanced at the woman and said, Where are the samples you left for lunch today The fat woman s eyes flashed, The students have finished eating, and we thought the samples were useless, so we ate them Eat Gong Daoyang took a deep look at this woman.Although this matter is completely left to Lu Zhongjiang, it would be a good thing if I Unlocking the Truth: Debunking Apple Cider Vinegar’s Weight Loss Hype in 2025 could contribute a little and help.
This thought only passed by for a moment. He turned around and looked at the tall woman and said, Are you the midwife Didn t you run away I.
She didn t run away. She went out to find the yellow paper.After finally resting, everyone takes the time to sleep in or take care of things.
In rural areas, especially those present now are all elderly people, and there are basically no electronic payments.After several days of treatment, the patient s previous condition has been greatly improved, especially the symptoms of being unable to close his eyes, crooked mouth, and stiff tongue.
In the end Circle, Du Bing and his father were like headless flies, staring blankly at the kang.Don t drink it in large gulps. Then he looked at the emergency doctor again, You Then add a small bottle of glucose to relieve nausea and vomiting caused by electrolyte imbalance.
This is a change since drinking your medicinal materials.Every time he came in and out, he would glance at the conspicuous red color intentionally or unintentionally.
It s okay. It won t affect the glorious image of your dean.I believe you already know it. Now I will verify whether you explained it to the patient at that time and how the patient responded to you.
It s not difficult to guess. After the examination, Du Heng hesitated.That s okay. With Du Heng s reply, the logistics person left, and he was going to inform him of this decision.
There are not many corpses in the secret room, there are four on each side, wearing hoods and all gray clothes of the same style.Raise your head and speak.Li Lingsu said.The maid Du Unlock Your Weight Loss Potential: The Top ACV Gummies for 2025 – A Comprehensive Guide Juan hesitated a little, then raised her head and bravely looked at Li Lingsu.
As for how to save Li Miaozhen, Xu Qi an s idea is to delay, drag to the next level of Qijue Gu, and then consider how to save people.If that s the case, senior brother will immediately send Chai Xian into Buddhism and hand it over to the master or Arhat who will take him back to the Western Regions.
He then opened the second letter, which was from Huaiqing.Lin an left angrily, and returned to Shaoyin Palace sullenly.
Searching, as if looking for something.Sister, can you use the method of a dream witch to trace back to who the owner of the dream is.If it were someone else, he would never reveal it But Xu Qian, who claims to have lived for hundreds of years, can tell the truth Li Lingsu thinks that the other party Fuel Your Transformation: Is Fit Flex Keto Gummies the Key to Lasting Weight Loss? may know the inside story better than himself.
Mental state is also very depressed.I will continue to update, but if I call in sick one day, it may take a long time to rest.After a pause, he put away The Future of Fitness: How Supplements Could Be California’s Go-To for Healthier Lives in 2025 his frivolous smile and said in a deep voice I heard that the emperor of Dafeng was beheaded by Xu Yinluo, and the court s notice said that Yuanjing was manipulated by the witch god religion, which is obviously impossible.
What s the explanation Her Zong Shengzi looked at him, frowning and said Your family can use her Gu shifting star changing ability to block the breath, we can t find it.puff The blade was stuck in the neck, and the head could not be chopped off.
In spring, the scenery is beautiful.In severe winter, it also has a special flavor.He was Unlock Your Weight Loss Potential: The Power of WebMD Keto ACV Gummies even more curious about the seriousness, why the family members suddenly looked depressed after losing a battle and had no fighting spirit.
You must also remember.Seeing several young monks who seemed to understand but half understood, most of them were at a loss, monk Jingyuan laughed and explained for Jingxin Said Before Chai Xing er said that Chai Xianxiu s inexplicable Transform Your Body with Keto ACV Gummies: A Gentle Path to Weight Loss and Digestive Wellness rapid progress is very interesting.Saying that, she closed her eyes and stretched her eyes.
Fortunately, the side effects of heart Gu and corpse Gu are just to make Gu masters like to be with animals and corpses.Mrs.Xu can compare.Sheng Zi talked eloquently, imparting experience, and then he regretted it, why should I teach Xu Qian Hurry up and fall out with the national teacher.
Xu Qi an suppressed his excitement and asked, Why didn t you tell me this in advance Something Sun Xuanji took up a pen and wrote The teacher is a chess player.He used three dragon energy hosts who had escaped into Buddhism as bait, and sent them to the east of the city.
Flying Swallow s heroine is still in style.Where s my little concubine Susu Did you take care of me As soon as the words came to her lips, she resumed the opening that echoed Xu Qi an s character.Li Miaozhen has fallen into their hands.There were a lot of question marks in Li Lingsu s mind.
I can t enter the pagoda, but I can help settle the pressure from the outside world.He walked briskly through rows of corpses, feeling that this was the safest and most comfortable place in the world.
Xu Qi an thought to himself, and then saw Li Lingsu sitting beside him, staring at Luo Yuheng obsessively.Xiangzhou, I am going to discuss this matter with you.
Even if it is Renzong, it is just a game of foolish kings.
