130. And summarizing the first component material and the second component material to generate a BOM bill of materials of the current product.
It should be understood that the target property information of the material includes target parameters of the material, for a resistor, the target property information includes a nominal resistance value, a nominal power and an allowable deviation value, for a capacitor, the target property information includes a nominal capacitance and tolerance, a nominal voltage, an insulation resistance, a loss frequency and a frequency characteristic, etc., and the target property information may further include a specific model or a brand.
In addition, the substitute material library is created by acquiring basic information of the main material, wherein the basic information comprises common attribute information and special attribute information.
It should be understood that the master material may be standard material information or the most frequently used material in the product. The common attribute information may be common parameters such as, for a resistor, a nominal resistance value, a nominal power, and an allowable deviation value, and the specific attribute information may be a specific model or a brand or a parameter specific to the material.
And determining the substitution relationship between the substitute material and the main material according to the comparison result of the basic information of the substitute material and the basic information of the main material, wherein the substitution relationship comprises complete substitution and high-grade substitution.
It should be understood that the common attribute information of the substitute material is compared with the common attribute information of the main material by using a first identification algorithm to obtain a first comparison result.
Wherein the first recognition algorithm may be various types of recognition algorithms. For example, the algorithm may be an algorithm for identifying the entire common attribute information, or an algorithm for identifying attribute information having a large difference among the common attribute information.
The first comparison result may have various manifestations. For example, the first comparison result may be in the form of a numeric value, or the first comparison result may also be in the form of a character indicating positive or negative.
And comparing the special attribute information of the substitute material with the special attribute information of the main material by adopting a second identification algorithm to obtain a second comparison result.
It should be understood that the second recognition algorithm is a different algorithm than the first recognition algorithm.
The second alignment may also take various forms. For example, the second alignment result may be in the form of a numerical value, or the second alignment result may be in the form of a character indicating positive or negative.
Determining weights for the first recognition algorithm and the second recognition algorithm.
And calculating based on the first comparison result, the second comparison result and the weight to obtain a third comparison result.
It should be understood that the operation may be performed in various forms, for example, when the first comparison result and the second comparison result are both in numerical form, the operation may be a weighted average of the first comparison result and the second comparison result, and when the first comparison result and the second comparison result are both in character form representing positive or negative, the operation may be a logical operation.
It is to be understood that the weight includes a first weight and a second weight;
and weighting the result by using the first weight and the first ratio to obtain a first weighted result.
And weighting the second comparison result by using the second weight to obtain a second weighted result.
And summing the first weighting result and the second weighting result to obtain a third comparison result.
And when the third comparison result meets the first preset condition, determining that the substitution relation between the substitute material and the main material is complete substitution.
And when the third comparison result meets a second preset condition, determining that the substitution relation between the substitute material and the main material is high-grade substitution, wherein the first preset condition is greater than the second preset condition.
And writing the basic information of the main material, the basic information of the substitute material and the substitution relation into a substitute material library.
It should be understood that the first preset condition and the second preset condition can be set according to actual requirements, and the first preset condition is related to the specific representation form of the comparison result. If the comparison result is in the form of a numerical value, the first preset condition may be a preset threshold. If the comparison result is in the form of a character representing the affirmation or the negation, the first preset condition may be yes.
The first comparison result may be a comparison score obtained by comparison using a first recognition algorithm, and the second comparison result may be a comparison score obtained by comparison using a second recognition algorithm. Assuming that the full score of the comparison result of the first recognition algorithm is 100 and the matching score is 85, that is, the first comparison result reaches 60 or more, the main material and the substitute material are matched in the first recognition algorithm. Assume that the full score of the comparison result of the second recognition algorithm is 100 and the matching score is 60. If the first comparison result is 50 points, the second comparison result is 70 points, the first weight is 0.5, the second weight is also 0.5, and the weighted sum result is 60 points. Assuming that the first preset threshold is 60 minutes, after weighted summation, the substitute materials which cannot be successfully matched in the first identification algorithm are successfully matched. The method in the embodiment can adjust the matching precision and is suitable for different product requirements.
In addition, in practical applications, the first weight and the second weight may be preset and used for multiple times, or the first weight and the second weight may be determined by self according to common experience before each weighting. Specifically, the first weight and the second weight are determined empirically, and the current product information may be identified and the first weight and the second weight may be determined based on the current product information before the operation is performed based on the first comparison result and the second comparison result.
Further, step 110 includes the following steps:
111. and extracting attribute parameters required by the target material from the target attribute information, and dividing the attribute parameters into common attribute information and special attribute information.
112. And determining the main material of the target material from the substitute material library according to the common attribute information and the special attribute information.
113. And obtaining a substitute material corresponding to the main material in the substitute material library according to the main material.

It should be appreciated that the priority of the attribute parameters required for the target material is determined. And calculating the priority value corresponding to the completely substituted material in the matched materials based on a preset priority value algorithm and the priority of the attribute parameters.
Based on the preset priority value algorithm and the priority of the attribute parameters, the priority value corresponding to the completely substituted material in the matched material can be calculated through a weighting system for determining the attribute parameters, the priority value can be obtained through calculating the weighting sum, or the priority value can be calculated through a self-defined mathematical formula, and the embodiment is not described in detail.
And taking the material with the priority value larger than a first preset threshold value corresponding to the completely-substituted material as the first component material.
And taking the materials with the priority values corresponding to the remaining completely-substituted materials larger than a second preset threshold value as second component materials.
