Therefore, reasonable material allocation is an important part of ensuring high-yield production of products. At present, the traditional method is to use manual processing to carry out material allocation, that is, to obtain material distribution requirements according to the production plan of the day; then the personnel will place the materials on the rack according to the experience and send them to the production line.

[0064] At the same time, the calculation method of the ratio coefficient of each material is as follows: (1) obtain the set production quantity of the target product; (2) obtain the required number of boxes of each material; (3) use the required number of boxes of each material to divide the set production quantity to obtain the ratio coefficient of each material.

[0065] The following example illustrates the calculation process of the ratio coefficient:

[0066] Assume that the set production quantity of the target product is 100 sets, and the required materials are material B, material C, material D and material E, and the required number of boxes of each material is 100, 200, 300 and 400, then the ratio of each material is 1:2:3:4, that is, the ratio coefficients of material B, material C, material D and material E are 1, 2, 3 and 4 respectively; of course, when the set production quantity of the target product and the required number of boxes of each material are other values, the calculation process of the ratio coefficient is the same as the previous example, and will not be repeated here.

[0067] After obtaining the production material parameters of the target product, the cumulative remaining quantity of each material on the production line during the k-1th round of production of the target product can be obtained, so as to subsequently construct a batching model based on this; wherein, the process of obtaining the cumulative remaining quantity of each material can be but is not limited to as shown in the following step S2.

[0068] S2. Determine the cumulative remaining quantity of each material on the production line when the target product is produced in the k-1th round, where the initial value of k is 1, and when k is 1, the cumulative remaining quantity of each material on the production line in the k-1th round of production is 0; in specific applications, for example, but not limited to, the following steps S21 and S22 can be used to calculate the cumulative remaining quantity of each material in the k-1th round of production.

[0069] S21. Obtain the actual number of supply boxes of each material and the actual production quantity of the target product in the k-1th round of production; in the present embodiment, it is equivalent to obtaining the actual number of supply boxes of each material and the actual production quantity of the target product in the previous round of production in the present round of production, and the aforementioned parameters are known values ​​in the previous round of production. Therefore, by recording the actual production quantity in the previous production and the actual number of supply boxes of each material, the accumulated remaining quantity of each material in the previous round of production can be calculated; optionally, the specific calculation process can be but is not limited to as shown in the following step S22.

[0070] S22. Calculate the cumulative remaining quantity of each material on the production line during the k-1th round of production based on the actual production quantity, the actual number of supply boxes of each material and the production material parameters; in specific applications, take the i-th material among the materials as an example to illustrate the specific calculation process of the cumulative remaining quantity, that is: for the i-th material among the materials required for the target product, based on the actual production quantity, the proportioning coefficient of the i-th material, the material storage quantity in the standard material box of the i-th material and the actual number of supply boxes of the i-th material (that is, the actual number of supply boxes calculated in the previous round), calculate the cumulative remaining quantity of the i-th material in the previous round (that is, the k-1th round) of production.

[0071] Furthermore, for example, but not limited to, the following formula (3) can be used to calculate the cumulative remaining quantity of the i-th material in the k-1th round of production.

[0072]

[0073] In the above formula (3), Indicates the cumulative remaining quantity of the i-th material in the k-1th round of production, Q i Indicates the ratio coefficient of the i-th material, S iIndicates the storage quantity of materials in the standard material box of the i-th material, represents the actual production quantity, It represents the actual number of boxes of the i-th material supplied in the k-1th round of production.

[0074] Thus, through the aforementioned formula (3), the cumulative remaining quantity of the i-th material in the k-1th round of production can be calculated; based on this, this principle is continuously cycled until i cycles from 1 to n, then the cumulative remaining quantity of each material on the production line in the k-1th round of production can be obtained, where n represents the number of material types.

[0075] Therefore, after calculating the cumulative remaining quantity of each material in the previous round of production through the aforementioned steps S21 and S22, the batching model can be constructed in combination with the production material parameters of the aforementioned target product, so that the materials can be batched based on the batching model in the future; wherein, the batching model construction process can be but is not limited to as shown in the following step S3.

[0076] S3. Construct a batching model based on the production material parameters and the accumulated remaining quantity of each material in the k-1th round of production; in specific implementation, this embodiment first calculates the maximum production quantity (i.e., the ideal production quantity) of the target product in this round of production; then, constructs the batching model based on the aforementioned maximum production quantity; wherein the aforementioned construction process can be but is not limited to as shown in the following steps S31 and S32.

[0077] S31. Calculate the ideal production quantity of the target product in the kth round of production based on the ratio coefficient of each material, the material storage quantity in the standard material box of each material, the number of material boxes and the cumulative remaining quantity of each material in the k-1th round of production; in specific applications, the following formula (1) can be used, for example but not limited to, to calculate the ideal production quantity of the target product in the kth round of production.

[0078]

[0079] In the above formula (1), r k represents the ideal production quantity of the target product in the kth round of production, V c Indicates the number of containers that can be accommodated, S i Indicates the storage quantity of the i-th material in the standard material box of each material, Q i represents the ratio coefficient of the i-th material, represents the cumulative remaining quantity of the i-th material in the k-1th round of production, where Represents the floor function, and n is the number of material types.

[0080] Thus, through the aforementioned formula (1), the ideal production quantity of the target product in the kth round of production can be calculated, and then, the batching model can be constructed by combining the ratio coefficients of the aforementioned materials, the material storage quantity and the accumulated remaining quantity of the previous round; wherein, the specific construction process of the batching model can be but is not limited to the following step S32.

[0081] S32. Construct the batching model based on the proportion coefficient of each material, the material storage quantity in the standard material box of each material, the ideal production quantity and the cumulative remaining quantity of each material in the k-1th round of production; in specific application, the batching model can be constructed according to the following formula (2) for example but not limited to.

[0082]

[0083] The above formula (2) represents the batching model, Q i Represents the ratio coefficient of the i-th material, r k represents the ideal production quantity of the target product in the kth round of production, Indicates the cumulative remaining quantity of the i-th material in the k-1th round of production, S i Represents the storage quantity of the i-th material in the standard material box, where represents a rounding function, and n is the number of material types. In this embodiment, it can be seen from the above formula (2) that the actual output of the batching model is the number of supply boxes of the ith material in the kth round of production. Therefore, based on this model, the number of supply boxes of each material in the kth round of production can be calculated.

[0084] After the batching model is constructed through the aforementioned steps S31 and S32, the number of supply boxes of each material in this round of production can be calculated based on it. The calculation process can be but is not limited to the following step S4.

[0085] S4. Based on the batching model, determine the number of supply boxes of each material required for the target product in the kth round of production; in this embodiment, the production material parameters of each material and the accumulated remaining quantity in the previous round of production are substituted into the above formula (2) and formula (1), and the number of supply boxes of each material in the current round of production can be calculated.

[0086] After calculating the number of supply boxes of each material in this round of production according to the aforementioned step S4, the number of material supply boxes can be adjusted in combination with the number of material boxes that can accommodate the material pallets of the production line, so as to maximize the distribution of materials while ensuring that the pallet capacity is not exceeded; wherein, the adjustment process of the number of material supply boxes can be, but is not limited to, as shown in the following steps S5 and S6.

[0087] S5. Determine whether the total number of supply boxes of each material in the kth round of production is greater than the capacity of the material box; in this embodiment, if the total number of supply boxes of each material calculated in this round is greater than the pallet capacity, then it is necessary to adjust the number of supply boxes; otherwise, it is not necessary; wherein, the material supply adjustment process can be but is not limited to as shown in the following step S6.

[0088] S6. If yes, then adjust the number of supply boxes of each material, so that after the adjustment, the actual number of supply boxes of each material in the k-th production round is obtained, and based on the actual number of supply boxes of each material, perform material batching of the target product in the k-th production round, wherein the sum of the actual number of supply boxes of each material is equal to the number of material boxes that can be accommodated; in specific applications, this embodiment adjusts the number of supply boxes of each material with the goal of minimizing the cumulative remaining number of each material on the production line, so that after the adjustment, the actual number of supply boxes of each material in the k-th production round is obtained; that is: according to the difference between the number of supply boxes of the material and the number of material boxes that can be accommodated, the number of material boxes to be reduced is determined; then, the traversal method is used to adjust the number of supply boxes of each material (that is, each material is adjusted once, and a combination of two, three or four materials is adjusted) to obtain a variety of adjustment schemes; then, a production simulation is performed, that is, the cumulative remaining number of each material after batching with each adjustment scheme and producing the target product is simulated; then, the adjustment scheme with the least cumulative remaining number is used as the actual number of supply boxes of each material in this round of production.

[0089] In this way, when this round of production is completed, the number of supply boxes of each material is adjusted, and after the actual number of supply boxes of each material is obtained, the material batching of the target product in this round of production can be carried out based on this; specifically, the actual number of supply boxes of each material in this round of production can be sent to the batching end, so that the staff at the batching end can batch according to the actual number of supply boxes; of course, the batching robot arm can also be combined to directly control the batching robot arm to grab the corresponding number of materials onto the pallet.

[0090] Based on this, after completing this round of production batching, the cumulative remaining quantity of each material in this round of production can be calculated, and then the above process can be re-executed until the production quantity of the target product reaches the above-mentioned set production data (i.e. the preset quantity described below), and then the batching process can be stopped; wherein, the cyclic batching process can be but is not limited to as shown in the following step S7.

[0091] S7. Add 1 to k and re-determine the cumulative remaining quantity of each material on the production line when the target product is produced in the k-1th round, until the production quantity of the target product reaches the preset quantity, so that when the production quantity reaches the preset quantity, the production material batching process of the target product is completed.

[0092] The following is an example to illustrate the aforementioned steps S1 to S7:

[0093] Further elaboration is given based on the above example, assuming that the number of material boxes that can hold the production line pallet is 12, the set production quantity of the target product is 100, and the ratio coefficients of the four materials are still 1, 2, 3 and 4; and the material storage quantities in the standard material boxes of the four materials are 20, 30, 40 and 50 respectively.

[0094] Then, in the first round of production, the accumulated remaining quantity of each material in the previous round of production is 0. At this time, substituting the above parameters into formula (1), the ideal production quantity of the target product in the first round of production is obtained as follows:

[0095]

[0096] After obtaining the ideal production quantity for the first round of production, it can be substituted into the above formula (2) to obtain the number of supply boxes of each material in the first round of production; among them, the number of supply boxes of material B is: (1×44-0) / 20=2.2, and then rounded up to 3; similarly, according to this principle, the number of supply boxes of C, D and E is calculated to be: 3, 4 and 4.

[0097] Based on this, in the first round of production, the total number of supply boxes of each material (14) is greater than the number of material boxes that the production line pallet can accommodate. At this time, the material needs to be adjusted, that is, the difference between the two is 2; then, the traversal method is used to adjust the number of supply boxes of the aforementioned materials so that the total number of supply boxes after adjustment is equal to 12; based on this, a variety of adjustment equations can be obtained; then, a variety of adjustment schemes are used to proportion materials and simulate the production of the target product to obtain the cumulative remaining quantity corresponding to each adjustment scheme; finally, the adjustment scheme with the smallest cumulative remaining quantity is used as the actual number of supply boxes of each material in the first round of production; if it is assumed that adjustment schemes 2, 3, 3 and 4 (that is, the adjusted number of supply boxes of materials B, C, D and E is 2, 3, 3 and 4), the corresponding cumulative remaining quantity is the least (of course, referring to the total cumulative remaining quantity of each material), then the actual number of supply boxes of each material is 2, 3, 3 and 4.

[0098] Next, the material batching for this round of production can be carried out based on the actual number of supply boxes; then, the accumulated remaining quantity of each material in this round of production is obtained, and the aforementioned steps S1 to S6 are re-executed until the production quantity of the target product reaches the preset quantity.

[0099] Thus, through the material batching method described in detail in the aforementioned steps S1 to S7, the present invention constructs a batching model through the production material parameters of the target product and the remaining cumulative quantity of each material in the previous round of production; then, the number of supply boxes of each material in each round of production is obtained according to the batching model, and the number of material boxes is adjusted in combination with the number of material boxes that can accommodate the pallet, so as to obtain the actual number of supply boxes of each material; finally, based on the actual number of supply boxes, the material batching of the target product can be carried out in each round of production until the production of the target product is completed; in this way, the present invention can maximize the use of the pallet capacity, thereby making full use of the rack space. At the same time, the number of material boxes transported each time is equal to the pallet capacity, based on which sufficient batching is guaranteed, the problem of production line breakage can be avoided, and production efficiency can be improved. Therefore, it is very suitable for large-scale application and promotion.
