All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, the present embodiment provides an e-commerce system based on supply chain management, which includes an inventory management module, an order generation module, an account management module, a fault repair module, a detection report management module, and a supplier management module;
the inventory management module comprises a part monitoring unit and a product monitoring unit, wherein the part monitoring unit is used for recording the part codes and the supplier codes of all parts and monitoring the inventory of all parts; the part code comprises a use position identification number and a part model identification number. The product monitoring unit is used for generating a service code containing part codes and supplier codes of all parts used for assembling the product.
The same part may be used in different positions of use of a product, such as a screw, may be used in a housing, and may be used in an internal component, but the external screw is more damaged than the internal screw due to exposure, so that it is necessary to distinguish the position of use of the part, and a part code of a part is, for example, 023.001 or 022.012, in which the three digits before the decimal point are a part model identification number indicating the 023 th part, and the three digits after the decimal point are a position of use identification number indicating that the part is used in the 001 th position of use. During production of the product, the parts of the same type are usually supplied by a plurality of suppliers, such as 007 or 015.
For example 023.001(007), which represents the information of a certain part in the product, and the service code is the information including all parts, i.e. the service code is a set, each element in the set is in the form of xxx.
The account management module is used for storing account information of a customer, sending the account information of the customer to the order generation module after the customer purchases products, and sending the account information of the customer to the fault repair module when the customer repairs;
the order generating module is used for screening out the service code of the product to be delivered through the product monitoring unit after receiving the account information, and then generating an order containing the service code and the account information of the product to be delivered; the system is used for correlating the account information, the service code of the product received by the client and the order.
The fault repair module is used for acquiring an order corresponding to the account information from the order generation module after receiving the account information, acquiring a service code of a product purchased by the customer from the order, performing repair by a maintenance worker after the product is in fault and repaired, filling in maintenance information and uploading the maintenance information to the fault repair module, and generating and storing a detection report after fault detection is completed by the fault repair module; the detection report comprises part codes, supplier codes and artificial damage information of damaged parts; the artificial damage information is artificial damage or non-artificial damage.
For example, if a detection report records that the product of non-artificial damage reported by repair has three damaged parts, namely 023.001(007), 023.001(008) and 023.004(007), the detection report shows that the parts 023 installed at the use position No. 001 have two damaged parts, wherein one damaged part is supplied by the supplier No. 007, the other damaged part is supplied by the supplier No. 008, and the part 023 installed at the use position No. 004 has one damaged part, and is also supplied by the supplier No. 007.
The detection report management module comprises a detection report classification unit and a content extraction unit, wherein the detection report classification unit is used for classifying all detection reports according to the detection reports and the artificial and damaged part codes;
the part damage caused by human factors can mislead the judgment of the part quality, so the human damage needs to be eliminated, and the analysis is carried out in products which are not artificially damaged.
The specific method for classifying all detection reports according to artificial damage information and damaged part codes by the detection report classification unit is as follows:
s1, acquiring artificial damage information of all detection reports, classifying the detection reports marked as artificial damage in the artificial damage information into one type, and classifying the detection reports marked as non-artificial damage into another type;
and S2, grouping all the detection reports which are not artificially damaged according to the same part model identification number to obtain a part group.
If all the non-human damage detection reports include 2 parts damaged, the 2 parts are each a part group, and parts of different use positions and suppliers may be included in the same part group. For example, the component group 23 is {023.001(001), 023.001(001), 023.004(001), 023.007(002), 023.006(002), 023.001(003), 023.001(002) }. The same numbers in parentheses indicate the same suppliers.
The content extraction unit is used for extracting each data in the detection report.
The supplier management module comprises a supplier ranking module and a part purchasing management module, and the supplier ranking module is used for ranking suppliers according to the data extracted by the content extraction unit; the part procurement management module is used for generating a procurement plan according to the supplier ranking and the inventory quantity of the parts.
The specific method for ranking the suppliers by the supplier ranking module is as follows:
SS1, selecting any part group;
SS2, classifying the elements in the part group according to the supplier codes in the part codes to obtain each supplier group;
if the part group 23 is {023.001(001), 023.001(001), 023.004(001), 023.007(002), 023.006(002), 023.001(003), 023.001(002) }, the division is 3 supplier groups: for convenience of illustration, the number of elements in the illustrated part group is small, and the data in each part group actually contains a large number of elements.
Supplier group 1 ═ {023.001(001), 023.001(001), 023.004(001) };
supplier group 2 ═ {023.001(002), 023.006(002), 023.007(002) };
supplier group 3 ═ {023.001(003) }.
SS3, counting the number of the same use position identification numbers in each supplier group, and recording a part damage set Pj ═ { p1, p2, …, pi, … }, wherein Pj represents the part damage set of the jth supplier group, and pi represents the damage number corresponding to the ith use position;
since the number of defects of the 001-use location provider group 1 is 2, p1 is 2, the number of defects of the 001-use location is 1, p4 is 1, the rest are 0, and so on, the following steps are performed
P1 corresponding to vendor group 1 is {2, 0, 0, 1, 0, 0, 0, 0 … };
p2 corresponding to vendor group 2 is {1, 0, 0, 0, 0, 1, 1, 0, … };
the P3 corresponding to the supplier group 3 is {1, 0, 0, 0, 0, 0, 0, … }.
SS4, calculating the proportion corresponding to each use position identification number in the supplier group, and recording as a proportion set Δ ═ { δ 1, δ 2, …, δ i, … }, wherein δ i represents the ratio of the damage number corresponding to the ith use position identification number to all damaged parts, and the calculation formula is δ i ═ pi/(p1+ p2+ … + pi + …);
for P1, if the ratio δ 1 of defective use positions for supply group 1, 001 is 2/3, the ratio δ 4 of use positions for 004 is 1/3, and the ratios of the remaining use positions are all 0, then for supplier group 1, the ratio set Δ is {2/3, 0, 0, 1/3, 0, … },
for supplier group 2, the ratio set Δ ═ 1/3, 0, 0, 0, 0, 1/3, 1/3, … },
for supplier group 2, the ratio set Δ ═ {1, 0, 0, 0, 0, 0, … }.
SS5, firstly calculating the median delta a of the proportion set, then calculating the difference between each non-zero element in the proportion set and the median delta a, marking the use position identification number with the difference higher than a preset value k1 as a high damage rate, marking the use position identification number with the difference lower than a preset value k2 or the proportion of zero as a low damage rate, and marking the rest as a medium damage rate;
the median δ a is calculated as δ a ═ δ max- δ min)/2, where δ min is the minimum value among the non-zero elements.
For example, in the supplier group 1, if δ a is 1/6, the difference value corresponding to the use position No. 001 is 1/2, and the difference value corresponding to the use position No. 004 is 1/6. k1 and k2 are empirical values and can be set according to actual needs. If k1 is set to 0.4 and k2 is set to 0.2, the 001 used position is marked as high damage rate and the remaining used positions are low damage rate.
SS6, calculating the ratio marked as high damage rate corresponding to the arbitrary use position identification number in all the supplier groups, wherein the calculation formula of the ratio of the high damage rate is L ═ LHeight of/lGeneral assemblyWherein l isHeight ofNumber of suppliers marked as high damage rate,/General assemblyIf the percentage of the total suppliers exceeds a preset value k3, the using position identification number is associated as a design defect, and if the percentage of the total suppliers does not exceed a preset value k3, the using position identification number is associated as a supply defect; k3 is an empirical value and can be set as needed.
Product part damage may be caused by both design defects and supply chain supply quality defects, so to accurately rank suppliers, damage caused by design defects should be removed.
If the label of each supplier group of the 001 use position is set as h ═ { high damage rate, low damage rate, medium damage rate }, then L ═ 1/3, and if k3 is set to 0.6, then the 001 use position should be associated as a supply defect.
SS7, sequentially acquiring marks of the use position identification numbers related to the supply defects in each supplier group, and calculating the quality score Q of each supplier, wherein the calculation formula is as follows:
Q＝m1*1+m2*0.5-m3*2；
wherein m1 is the number of used location identification numbers marked as low damage rate, m2 is the number of used location identification numbers marked as medium damage rate, and m3 is the number of used location identification numbers marked as high damage rate;
the quality score Q can reflect the quality of supply of the part by the supplier as a whole.
SS8 ranks suppliers from high to low according to quality score Q.
If the number of the use location identifiers marked as low damage rate in the supplier group 1 is 30, the number of the use location identifiers marked as medium damage rate is 20, and the number of the use location identifiers marked as high damage rate is 10, Q1 is 20.
The number of used location identifiers marked as low damage rate in the supplier group 2 is 10, the number of used location identifiers marked as medium damage rate is 30, and the number of used location identifiers marked as high damage rate is 20, then Q2 is-15. So vendor group 1 is ranked higher than vendor group 2.
The specific method for generating the purchasing plan by the part purchasing management module according to the supplier ranking and the part inventory is as follows:
when the stock quantity of any part is less than a preset value k4, the part procurement management module acquires the planned procurement quantity and the supply quantities of all suppliers, and sequentially selects the highest-ranked supplier as the supplier of the part, if the supply quantity of the first supplier is less than the planned procurement quantity, the second supplier is selected for supplementary procurement until the total supply quantity is greater than the planned procurement quantity. K4 is a preset value and can be set according to actual conditions as required.
The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the invention as defined in the following claims.
