Technique of material Coding management

A, the material coding management rules need to reflect as much as possible material categories.
The large category of material allows us to have a direct judgment on the category of the item. For example, we use mobile phones every day,
If we see number 139th, we know it's a mobile call. The classification principle of large class is often: The first code: produce
Products, semi-finished products, raw materials, excipients, low-value consumable, mainly for financial use; second code: The real category, according to the Enterprise does not
Specific development of the same situation.
b, coding needs moderate length.
According to People's memory habits, 7-13-bit encoding is more reasonable.
C, try not to use a particularly meaningful encoding.
Many of the original purpose of material coding is to articulate the material, such as the steel plate into GB, easy to understand. But with
An increase in the type of material, GB-encoded materials are no longer limited to "steel", "pen" is named GB.
D, avoid using characters that are difficult to communicate and differentiate.
The text represents the Chinese nation's profound culture, pinyin is also known as one of the most complex characters in the world. If the simple
Through phonetic alphabet, such as G and J, most people will be difficult to differentiate because of the non-standard pronunciation. In addition, the letter L of the small
After the print out and the number 1 no difference, o print out and the number 0 no difference and so on. We're making coding rules.
In the process, try to avoid using these characters that are prone to confusion.
E. Do not encode information that is likely to change.
What is a possible change in information? For the simplest example, many enterprises now set the employee Code rule as: Department number
+ Serial code. I think this is the most unreasonable code, if staff changes or post change, the code can not
Accurately describe the department in which it is located. If the personnel and job changes frequently, the code becomes the enterprise's trouble
