1. Tại sao cần mã hóa thiết bị và vật tư phụ tùng và các nguyên tắc chung
Mã được coi là tên ngắn của 1 đối tượng, không trùng lắp, khó sai sót, được sử dụng để thay thế tên gọi đầy đủ của đối tượng trong các phần mềm quản lý.
Thí dụ, chúng ta có 2 máy nén khí giống hệt nhau cùng mua về 1 ngày. Tuy nhiên, chúng ta cần quản lý chúng như 2 đối tượng khác nhau vì chúng có lịch sử sử dụng và bảo trì khác nhau. Do vậy, chúng ta không thể gọi chúng bằng tên chung là máy nén khí được.
Chúng ta cần gọi chúng là Máy nén khí số 1 và Máy nén khí số 2 để phân biệt chúng với nhau. Tuy nhiên, khi đưa tên gọi này vào phần mềm quản lý sẽ dẫn đến những bất cập sau:
Chúng quá dài, nên việc tìm kiếm sẽ chậm hơn.
Có các khoảng trắng ở giữa chuỗi ký tự nên rất dễ sai sót (bạn khó nhìn thấy để phân biệt chuỗi ký tự có 1 khoảng trắng và 2 khoảng trắng, còn máy tính thì coi 2 trường hợp này là các chuỗi ký tự khác nhau).
Để tạo thuận lợi cho việc truy vấn dữ liệu, người ta thực hiện mã hoá thiết bị và vật tư (các đối tượng cần quản lý bằng phần mềm quản lý bảo trì CMMS (Computerized maintenance management system), tương tự như việc cấp số căn cước cho các công dân.
Mã hoá thiết bị và vật tư cần phải thỏa mãn các yêu cầu sau:
(1) Hai đối tượng khác nhau phải có 2 mã khác nhau (tức là yêu cầu không trùng lắp).
(2) Ngắn gọn nhất có thể (để máy tính truy vấn cho nhanh).
(3) Có tác dụng gợi nhớ, thí dụ Máy nén khí có thể có mã MNK001 và MNK002, trong đó MNK là ký tự đại diện cho Máy nén khí.
(4) Các đối tượng cùng loại nên có chung các ký tự đại diện (để dễ sort). Các ký tự phân loại cấp cao thì đứng trước, cấp thấp thì đứng sau, cuối cùng là chuỗi ký tự số với số ký tự đủ dài để tránh tràn dữ liệu. Thí dụ chúng ta có máy nén khí trục vít và máy nén khí piston. Chúng ta có thể mã chúng thành MNK-PS-001 và MNK-TV-001, trong đó PS đại diện cho Piston và TV đại diện cho Trục vít.
2. Các chú ý khi thực hiện mã hóa thiết bị và vật tư phụ tùng
Yêu cầu (3) và (4) được nêu trên đây dẫn đến yêu cầu phân loại đối tượng (mà ở đây là thiết bị hay vật tư phụ tùng).
Có nhiều cách phân loại đối tượng, thí dụ: phân loại theo loại đối tượng (như được trình bày phía trên cho máy nén khí); phân loại theo địa điểm lắp đặt (thí dụ, máy lắp tại phân xưởng A, phân xưởng B); phân loại theo đối tượng sử dụng (thí dụ phụ tùng máy nén khí).
Chọn cách thức phân loại trong đặt mã rất quan trọng vì nó kéo theo nhiều hệ lụy trong quá trình sử dụng mã.
Nguyên tắc chung khi mã hoá thiết bị và vật tư phụ tùng là phân loại dùng trong đặt mã phải là phân loại theo đặc tính bất biến.
Thí dụ, máy nén khí thì luôn luôn là máy nén khí, nó không bao giờ thay đổi. Thuộc tính Loại máy, nhóm máy, loại vật tư, phụ tùng thường rất hay được dùng để phân loại đặt mãThuộc tính địa điểm cũng có thể dùng để phân loại dùng trong đặt mã, nếu chúng bất biến. Thí dụ, một dây chuyền nung xi măng, chúng không có khả năng bị di dời từ nơi này sang nơi khác. Bạn có thể sử dụng phân loại này để đặt mã.
Hay, có những phụ tùng chỉ dùng duy nhất cho loại máy nhất định (đối tượng sử dụng), bạn có thể dùng phân loại của thuộc tính này để làm phân loại đặt mã.
Cuối cùng, bạn luôn phải có các ký tự chạy, thí dụ 001 vào cuối để phòng hờ việc xuất hiện các đối tượng cùng loại trong tương lai, dù hiện nay bạn chỉ có duy nhất 1 đối tượng. Số lượng ký tự chạy tương ứng với số lượng đối tượng tối đa có thể xuất hiện, thí dụ: 01 tương ứng với số lượng tối đa là 99; 001 thì tương ứng với số lượng tối đa là 999.
Nếu bạn chú ý những điểm trên đây, bạn sẽ có một hệ thống mã hóa đẹp, ổn định và quy tắc đặt mã bền vững.
Bạn có thể thấy nội dung này khá đơn giản, nhưng rất nhiều nhà máy đã vấp phải các bất cập trong việc đặt mã, do không chú ý đến các vấn đề đơn giản trên đây.
3. Cách mã hóa vật tư phụ tùng
Số lượng vật tư phụ tùng ở các đơn vị sản xuất thường rất lớn, đến hàng ngàn, thậm chí hàng chục ngàn. Việc mã hóa vật tư phụ tùng do đó khá phức tạp.
Bạn cũng bắt đầu bằng việc phân loại như đã được trình bày phía trên. Số cấp phân loại sẽ phụ thuộc vào số lượng vật tư phụ tùng bạn cần mã hóa. Thí dụ, dưới 3,000 vật tư phụ tùng, bạn chỉ cần chia 2 cấp, nhưng nếu bạn có trên 3,000 phụ tùng thì có lẽ bạn cần chia làm 3cấp.

But there is a premise for this absolute advantage that is, Long Yun and others spend most of their energy on fighting with the dome without blame.He paused, smiled, and said very confidently This strategy is not a secret, but I know it will succeed.
Because the Taoist skills taught by Shi Mo were obviously more advanced than those taught by Gui Wujiu, the Taoist skills training went more smoothly this time.Among the eight hall masters, one of the subordinates of the Mingtang hall master on the lower right seems to be a figure who has just broken through the Fusion Realm.

compare with the two people who just competed Gui Wujiu smiled but did not answer.
His mastery is naturally far above his own. Huang Xiyin is here.The twelve tall trees, together with the grass leaves and flowers, were shaking violently Most of them returned to calm after swaying but there were also about 20 to 30 of them, which shook gently and manifested human forms.
Huang Xiyin glanced at Gui Wujiu and said with a smile, Why not.It turns out that just now, Dao Zun Ying Yuan suddenly realized that he seemed to have lost the sharp determination he had when this battle started.
There are exceptions, but this recent Dharma conference, blameless is the first exception, and it has been accomplished in less than a hundred years.After Xian Dao Dao Zun has settled down, he closes his eyes and regulates his breathing.
Yu Xuanyang was secretly surprised.

Xi Lerong s decision was based on two reasons. One of them is the contrast between general trends and innate talents and luck.With this certainty at this time, his method must not be underestimated.

The figure of Yin Yang Dao Master flashed and he had already fled to the side of the Copper Palace.Li Yunlong s attack was indeed impressive, but he was not able to exert it as fully as he had achieved this state.
But fate plays tricks on people, and this jade cicada happened to have one in her hand.But unexpectedly, Taoist Hanzhen shed a tear, but he was also very calm, and even said, If I were the first to see the talisman, I would have made the same decision as you this made Xuan Mu Tao Zun was a little sad and in a daze.
After Mo Tianqing entered the formation, he sensed the characteristics and energy of the Yue Heng Sect s protective formation.After thinking about it, Qin Menglin simply waved his hand and asked directly Mu Xiang.
All the true monarchs of the Nine Sects, especially those who have recently achieved shortcuts, are among his challenges.Because the Shinto method was originally the main method for breaking through rocks.
Maybe the loopholes can be repaired and the ruthless people can be excluded.Wei Qingqi and Du Niansha s hearts moved, and they each took a look at it.

An increase of more than a hundred times Everyone present was shocked when they heard this number, and Fang Hong continued Not only the companies in our galaxy, but also other large companies that need a lot of traffic support, in such a huge traffic In front of him, he can sponsor a club for fun.
When they saw someone holding an S3 mobile phone, they went up to them and asked if they wanted to sell them.The entire network was overwhelmed and netizens could not sit still.
When When important good news appears on the policy front, it is when the market recovers.It s only natural that Qiu Guangcheng would be so imaginative when things like this happened.
The cash subsidy is 6,000 yuan for a second child, which can significantly alleviate the financial pressure caused by childcare during the preschool period.Spending 50 billion US dollars is more than the market value of six Internet companies, or equal to the combined market value of EA T2 Sega Capcom SE.

The figure that suddenly appeared was naturally the iron armed monkey.Arranging a task every once in a while, without wasting too much time, the reward is relatively generous, and it saves you worry, no one thinks it is inappropriate.
Jiao Hong said He didn t mind that Qingyang didn t answer his question.Three Yuan Sword Technique. Qingyang gave an order, and three magical swords, the Green Bamboo Sword, the Blue Wave Sword, and Her That Transformed Body Lori Tricks Weight Harvey Journey Loss s Halloween
the Golden Shadow Sword, appeared in the air at the same time.
Wei Yufeng took the initiative to retreat, but he didn t expect that the living dead would not let him go.Continue Staying here might arouse suspicion, so Master Lingxu frowned unwillingly, and then stepped out of the forbidden area of Chaotic Demon Valley.

In the past, I just felt that there was something wrong with Qin Ruyan s character, but now I finally know what the problem is.
The root cause of today s incident is that Qin Menglin broke through the realm much faster than imagined So much so that neither of them thought of it.Give the remaining half to You. After saying this, Shu Shen Yun glanced at everyone in the palace.
Long Yun said calmly, Yeah Sounded. In fact, there was no need to answer Taoist Yuan s explanation.However, this opportunity seems to be close but is actually far away.
Xi Lerong, Long Yun, Feng Qing, Xian Dao, Ying Yuan and others were all solemn and decisive, their eyes firmly fixed on the five lotus barriers.The Yin Sect and the Yao Clan, which are local forces, will not have any surprises but for the Jiu Sect, after all, Mr.

You, me, and the clones unite with the Nine Heavens and Nine Emperors.Seeing the giant dragon circling for a while, gathering enough strength, it was about to fly away between the sky and the earth, a jade colored fist suddenly appeared This fist seems to have an ethereal shape, and its edges and corners are like the lines connected by constellations but it gives people an illusion for no reason, as if the weight of this punch is stronger than any heaviest black iron sand.
There is no absolute certainty, and you will never go too far.We got the opportunity in advance today, how could we miss it.
The second is the sword Xuanyuan. When Xuanyuan Huai used that sword, Gui Wujiu could clearly feel that the power of this sword was extremely mysterious, obviously more powerful than any of the eight swords of Chenyang he used.It can be said that all direct descendants of the hidden sect today will be affected by it.
Mr. Mood was about to make a move when suddenly his body froze, and he looked really surprised.Two endings, repeated over and over again. In the blink of an eye, graphite already had the answer.
