[0049]

[0050] 8) Combined with the relevant information included in the above-mentioned failure part coding rules, the logical relationship of the failure part coding is uniformly constructed, and finally the overall rules for the diesel engine failure part coding are formed; specifically, the overall rules for the diesel engine failure part coding are composed of nine groups of codes consisting of sixteen digits including text, letters, and numbers; the specific details are as follows:

[0051]

[0052] Group A consists of a single letter, indicating the product category;

[0053] Group B consists of two letters, indicating the product code;

[0054] Group C consists of a single digit, indicating the type of project;

[0055] The D group consists of a letter, indicating the category of the failed part;

[0062] Among them, in this solution, the "invalid product attribute information rule base" is used as an example for explanation. The user filters the invalid product attribute information according to the corresponding rules and incorporates it into the invalid product attribute information rule base. The rule base can be customized according to actual needs, such as:

[0063] Invalid product attribute information rule base table:

[0064] Field Number Field Name Remark 001 Product Category 002 Product Name 003 Product Model 004 Product Number … …

[0065] Invalid item property information rule base table:

[0076] Invalid part storage attribute information rule base table:

[0077] Field Number Field Name Remark 001 Storage environment requirement level 002 Storage time 003 Storage location … …

[0078] Each information rule base is customized according to the different needs of different manufacturers.
