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.

When you learn it later, you will understand it naturally.Du Heng also squatted next to Dong Yuezhang, asked for another bag, and picked it up himself.
Dean, I m back. Before anyone came in, a happy Beyond the Blue Pill: Exploring Side Effects and a Better Route for Men’s Health voice came into the office, and then Kang Zhirong walked in with a shy face and a smile.In desperation, Xiao Ma could only look at the female patient again, and waited for her vomiting to subside a little before saying, You may not believe what I say.
Gong Daoyang heard the sound and walked directly inside.He didn t think that the eldest sister was faking, because the eldest sister s pale face and purple lips showed that there was something Unlock Your Peak Performance: What to Know About An 351 wrong with her heart.

Oh Oh The kidnapping man became even angrier and turned his buttocks to block Big Ball s face.However, Du Heng saw another familiar person, Xiao Ma, why are you in the clinic Senior Brother Du, the teacher has been arrested.
It s a normal reaction. Don t make a fuss. But Wu Shengnan still lowered his voice and said quickly, But Captain Zhang suddenly felt pain all over his body and wouldn t let anyone touch him at all.Just like myself, jumping from the health center to the municipal maternal and child care department was definitely not something that could be achieved by performance.
He said softly, Continue to keep in touch with the mountain and learn about the latest situation at any time.After Du Heng called twice, he stopped calling when Dong Yuezhang didn t answer his call, and drove directly to the Provincial No.
But compared to before the New Year Boost Your Weekend – How Friday Plans 100mg Can Set You Up for Success s Eve holiday, Liu Amei s overall complexion began to improve, her complexion became rosy, no longer the black and gray before, and her cheeks also became slightly fleshy.Don t move, don t move. Du Heng shouted and ran quickly towards Qi Cai.
Du Heng, who escaped, had a good sleep at night. When he got up in the morning to prepare for work, he saw Du Ping, who had gotten up early and had returned from feeding the sheep.I really didn t expect that there would be such an unexpected surprise on the day before the Chinese New Year.
Fortunately, halfway down the aisle, Du Heng answered the phone.Being a little older, he didn t want to see a few young people snatching their good wine, so he directly kicked out some of Du Heng s peers, Children, you go find a place to drink by yourselves.
No. Du Heng s reply was direct enough. I met this woman several times, but nothing good happened every time.Just as he was about to speak, Gong Daoyang s voice came from behind him, Dean Du, come and take a look.

Pure manipulation to push the broken bones back into place is the biggest gain this time.It s fine tonight. Let s go home. Du Xueting was not happy to be disturbed. She walked to Du Heng s new car with her mouth pouted and Unlock Your Peak Performance: What to Know About An 351 got straight into it.
At the end, he pulled the director of the emergency department up and said, Get out of the way and let me see clearly.Do patients need celebrity endorsements Do our medicines need the fan effect None of them , what patients need is curative effect, what we need is word of mouth.
Judging from their grades, the first The foundation of the first place is much stronger than that of the second place, especially the basics of traditional Chinese medicine, which is nearly 20 points higher.Du Heng didn t look surprised, and the child slowly relaxed.
You can only give one third of these powders. It is better to give less than more.Du Heng nodded and affirmed again. Laughter and applause instantly filled the ward.
But the development of things always exceeded his expectations.He had a bad guess that his treatment idea might be wrong.
At this time, the doctor who just spoke suddenly said, Does this Doctor Du have any better solution for Officer Wu s condition Du Heng nodded, In my personal opinion, Miss Wu s condition is not yet at the point where amputation is necessary.After sending Zhao Xingde away, Du Heng immediately asked the nurse to prepare the decoction he prescribed.

The female doctor said a little embarrassedly, Actually, strictly speaking, he is not my teacher, but my husband s teacher.Then Director Zheng was really eye catching and stood up to leave without interrupting Du Heng and the two of them finishing their meal.
But looking at Du Heng s current appearance, Du Xueting asked carefully, Uncle, did you and Boost Your Bedroom Confidence: How Viagra Boys Rym Connects to Male Enhancement your aunt quarrel Du Heng looked back at his niece, and seeing her worried look, he chuckled and said, What are you thinking about We didn t quarrel, our relationship is good.You can do research and development with peace of mind, and I can concentrate on management and sales.
