[0003] With the rapid development of Industry 4.0 and smart manufacturing, the automation and intelligence levels of industrial production lines are constantly improving. Traditional production line efficiency optimization methods mainly rely on manual experience or simple mathematical models, which are difficult to cope with complex production environments and changing production needs. Especially in multi-node and multi-process industrial production lines, the production efficiency of each node is often unbalanced, resulting in the overall efficiency of the production line cannot be optimized. In addition, factors such as material supply, equipment status, and coordination between processes will also have a significant impact on the overall efficiency of the production line. Existing efficiency optimization methods usually focus on the optimization of a single node and lack a global consideration of the overall efficiency of the production line under all working conditions.

[0032] Furthermore, as a refinement and extension of the specific implementation methods of the above-mentioned embodiment, in order to fully illustrate the specific implementation process in this embodiment, some implementation methods of the full-operating efficiency optimization method of an industrial production line are provided, and the method includes the following steps.

[0033] In step 101, the material supply on the industrial production line is obtained, and the output distribution of the industrial production line is determined in combination with the production efficiency of each node on the industrial production line.

[0034] In specific implementation, the industrial production line is an automobile manufacturing assembly line. The production efficiency of each workstation in the automobile manufacturing assembly line varies greatly (such as welding robot speed vs. manual interior installation), and dynamic balance is required. In addition, the industrial production line can also be other discrete, multi-process industrial production lines, such as electronic assembly and mechanical parts processing, which will not be repeated here.

[0035] After turning on the equipment at each node on the industrial production line, the material is transported to the equipment at the first node on the industrial production line, and the material supply amount on the industrial production line is collected through the weight sensor in the equipment at the first node, wherein the material supply amount represents the weight of the material supplied by the industrial production line during production; in other embodiments, other methods may also be used to obtain it, which is not limited here.

[0036] It should be noted that the industrial production line in the present application is composed of multiple production equipment, and each production equipment is regarded as a node, and each production equipment constitutes an industrial production line according to the production process, that is, each node has a production sequence.

[0037] In specific implementation, the output distribution of the industrial production line can be determined in combination with the production efficiency of each node on the industrial production line. The following method can be used, namely: the output of each node is calculated based on the material supply and the production efficiency of each node on the industrial production line, namely: the output of the first node = material supply * production efficiency of the first node, the output of the second node = output of the first node * production efficiency of the second node, and so on. The output of the last node = output of the second-to-last node * production efficiency of the last node, thereby obtaining the output of each node, distributing the output correspondingly on each node of the industrial production line, and using the obtained distribution as the output distribution of the industrial production line, wherein the output distribution represents the distribution of the output of each node on the industrial production line; in other embodiments, other methods can also be used to determine, which are not limited here.

[0038] In step 102, a balance constraint is imposed on the output distribution of the industrial production line to obtain a balance index of each node in the production process of the industrial production line.

[0039] In some embodiments, reference Figure 2 As shown, this figure is a schematic diagram of a process for determining a balance index in some embodiments of the present invention. In this embodiment, the output distribution of the industrial production line is subjected to a balance constraint, and the balance index of each node in the production process of the industrial production line is obtained, which can be achieved by the following steps: First, in step 1021, the constraint parameters of the industrial production line are determined; Secondly, in step 1022, a node is selected as a selected node, and the output quantity and the corresponding position of the output quantity corresponding to the selected node are extracted from the output quantity distribution of the industrial production line; Furthermore, in step 1023, the balance index of the selected node in the production process of the industrial production line is determined according to the constraint parameters, the output corresponding to the selected node and the position corresponding to the output; Finally, in step 1024, the balance index of the remaining nodes of the industrial production line in the production process continues to be determined.

[0040] In specific implementation, determining the constraint parameters of the industrial production line can be achieved in the following manner, namely: obtaining historical production data of the industrial production line from the corresponding database of the industrial production line, namely: the historical production data includes the output and supply of each node in the historical production, dividing the average value of all historical supply quantities corresponding to the first node in the historical production data by the average value of all historical output quantities, performing a logarithmic operation with a base of 2 on the value obtained by the division, and using the value obtained by the logarithmic operation as the constraint parameter of the industrial production line, wherein the constraint parameter represents a parameter constraining the efficiency of the industrial production line in the production process; determining the balance index of the selected node of the industrial production line in the production process according to the constraint parameter, the output quantity corresponding to the selected node and the corresponding position of the output quantity can be achieved in the following manner, namely: multiplying the constraint parameter with the output quantity corresponding to the selected node, and dividing the multiplied value by the corresponding position of the selected node (i.e., the corresponding position of the selected node in the production sequence during the production process), and using the divided value as the balance index of the selected node of the industrial production line in the production process; in other embodiments, other methods can also be used for determination, which are not limited here.

[0041] It should be noted that the balance index in the present application represents the parameter value of the output when the nodes on the industrial production line are in a balanced state during production, and can be used to adjust the nodes of the industrial production line to improve the efficiency of the industrial production line.

[0042] In step 103, the bottleneck sequence of the output volume corresponding to each node of the industrial production line is determined according to the difference characteristics of all balance indexes, the efficiency deviation of the industrial production line is determined by the bottleneck sequence and the production efficiency of each node, and the production efficiency between each node on the industrial production line is correlated and matched through the efficiency deviation to obtain the matching degree of the production efficiency between each node.

[0043] In some embodiments, determining the bottleneck sequence of the output corresponding to each node of the industrial production line according to the difference characteristics of all balance indexes can be implemented by the following steps: Determine the differential characteristics of all balance indices; Determine the bottleneck volume of each node based on the difference characteristics; All bottleneck quantities are arranged in the order of the corresponding nodes on the industrial production line, and the sequence obtained by arrangement is used as the bottleneck sequence of the output quantity corresponding to each node of the industrial production line.

[0044] In specific implementation, determining the difference characteristics of all balance indexes can be implemented in the following manner, namely, arranging all balance indexes in the order of corresponding nodes on the industrial production line, and using the sequence obtained by the arrangement as the balance index sequence, selecting a group of adjacent balance indexes in the balance index sequence as selected adjacent balance indexes, subtracting the first balance index from the second balance index in the adjacent balance indexes, and using the value obtained by the subtraction as the difference value of the selected adjacent balance indexes, continuing to determine the difference values ​​of the remaining adjacent balance indexes in the balance index sequence, and using all the difference values ​​as the difference characteristics of all balance indexes, wherein the difference characteristics represent the characteristics of the degree of difference of the adjacent balance indexes; determining the bottleneck amount of each node according to the difference characteristics can be implemented in the following manner, namely, calculating the maximum difference amount in the difference characteristics minus the minimum difference amount, and using the value obtained by the subtraction as the first value, subtracting the first value from the balance index of each node, and using each subtraction value as the bottleneck amount of the corresponding node, wherein the bottleneck amount represents the lowest output of the node in the production process; in other embodiments, other methods can also be used for determination, which are not limited here.

[0045] It should be noted that the bottleneck sequence in the present application represents the sequence of the output of each node when the industrial production line is in production at the slowest production efficiency, and can be used to adjust the efficiency of the industrial production line.

[0046] In some embodiments, determining the efficiency deviation of an industrial production line based on the bottleneck sequence and the production efficiency of each node can be implemented by the following steps: Determine the efficiency gain of each node based on the bottleneck sequence; The efficiency deviation of the industrial production line is determined by all the efficiency gains and the production efficiency of each node.

[0047] In specific implementation, the efficiency gain of each node is determined according to the bottleneck sequence, which can be implemented in the following manner, namely: select a node as the selected node, extract the bottleneck amount corresponding to the selected node from the bottleneck sequence, perform natural exponential operation on the extracted bottleneck amount, and use the inverse of the value obtained by the natural exponential operation as the efficiency gain of the selected node, and continue to determine the efficiency gain of the remaining nodes, wherein the efficiency gain represents the parameter value of the gain degree of the production efficiency of the node; determine the efficiency deviation of the industrial production line through all the efficiency gain amounts and the production efficiency of each node, which can be implemented in the following manner, namely: select a node as the selected node, subtract 1 from the efficiency gain amount corresponding to the selected node, multiply the value obtained by the subtraction by the production efficiency of the selected node, and use the multiplied value as the deviation of the production efficiency of the selected node, and continue to determine the deviation of the production efficiency of the remaining nodes, wherein the deviation represents the parameter value of the deviation degree between the production efficiency of the node on the industrial production line and the minimum production efficiency, and all the deviations are used as the efficiency deviation of the industrial production line; in other embodiments, other methods can also be used for determination, which are not limited here.

[0048] It should be noted that the efficiency deviation in this application indicates the degree of deviation of an industrial production line from the minimum production efficiency during the production process, and can be used to adjust the industrial production efficiency, thereby improving the production efficiency of the industrial production line.

[0049] In some embodiments, the production efficiency between each node on the industrial production line is correlated and matched by the efficiency deviation, and the matching degree of the production efficiency between each node can be obtained by the following steps: Determine the correlation between production efficiency of each node on the industrial production line based on efficiency deviation; The matching degree of production efficiency between each node is determined through all the correlation quantities.

[0050] In specific implementation, the correlation between the production efficiency of each node on the industrial production line can be determined according to the efficiency deviation. The following method can be used to achieve this, namely: randomly select two nodes as the selected two nodes, subtract the deviation corresponding to the first node of the selected two nodes from the deviation corresponding to the second node of the selected two nodes in the efficiency deviation, and use the subtracted value as the first value, subtract the production efficiency of the first node of the selected two nodes from the production efficiency of the second node, and use the subtracted value as the second value, add the first value and the second value, and use the added value as the correlation between the production efficiency of the selected two nodes on the industrial production line. , and continue to determine the correlation quantity of production efficiency between the remaining nodes on the industrial production line, wherein the correlation quantity represents the parameter value of the correlation degree between two nodes on the industrial production line; determining the matching degree of production efficiency between each node through all the correlation quantities can be implemented in the following manner, namely: randomly selecting two nodes as the selected two nodes, performing a natural exponential operation on the correlation quantity of the selected two nodes, and taking the inverse of the value obtained by the natural exponential operation as the matching degree of production efficiency between the selected two nodes, and continue to determine the matching degree of production efficiency between the remaining nodes; in other embodiments, other methods can also be used for determination, which are not limited here.

[0051] It should be noted that the matching degree in this application represents the parameter value of the matching degree of production efficiency between two nodes on an industrial production line, which can be used to jointly adjust the production efficiency on the industrial production line, thereby improving the efficiency of the entire production line.

[0052] In step 104, the distances between adjacent nodes on the industrial production line are collected, and the buffer zone of materials in the production process of the industrial production line is determined according to all the distances and the production efficiency of each node.

[0053] In specific implementation, the distance between each adjacent node on the industrial production line is collected by a distance sensor, and the distance represents the distance between the output position of the first node and the input position of the second node among the adjacent nodes; in other embodiments, other methods can also be used for collection, which are not limited here.

[0054] In some embodiments, determining the buffer zone of materials in the production process of an industrial production line according to all distances and the production efficiency of each node can be achieved by the following steps: Determine the distance difference characteristics for all distances; Determine the efficiency difference characteristics of the production efficiency of each node; The buffer zone of materials in the production process of industrial production lines is determined by distance difference characteristics and efficiency difference characteristics.

[0055] In specific implementation, the distance difference characteristics of all distances can be determined by the following method, namely: all distances are arranged according to the corresponding positions on the industrial production line, and the difference values ​​between each adjacent distance are calculated, and all the difference values ​​are used as the distance difference characteristics of all distances, wherein the distance difference characteristics represent the characteristics of the degree of difference in distances between each node on the industrial production line; the efficiency difference characteristics of the production efficiency of each node can be determined by the following method, namely: all production efficiencies are arranged according to the corresponding node positions on the industrial production line, and the difference values ​​between each adjacent production efficiencies are calculated, and all the difference values ​​are used as the efficiency difference characteristics of the production efficiency of each node, wherein the efficiency difference The different features represent the features of production efficiency on the industrial production line; determining the buffer zone of materials in the production process of the industrial production line through the distance difference features and the efficiency difference features can be achieved in the following manner, namely: using a machine learning algorithm (such as random forest, neural network) combined with the historical stagnation area of ​​materials on the industrial production line to establish a material buffer zone prediction model, the input features of the model include difference features, and the output features are buffer zones, the distance difference features and the efficiency difference features are input as input features into the change trend prediction model, and the buffer zone prediction model of the material outputs the buffer zone of the materials in the production process of the industrial production line; in other embodiments, other methods can also be used for determination, which are not limited here.

[0056] It should be noted that the buffer zone of the material in the present application refers to the area where the material stagnates during the production process of the industrial production line, that is, all areas where the material stagnates during the entire production process, which can be used to adjust the production rate between each node and use the buffer zone to improve the efficiency of the industrial production line.

[0057] In step 105, the production rate of each node on the industrial production line is optimized and adjusted through all matching degrees and material buffers to obtain the optimized rate of each node, and the equipment of each node on the industrial production line is controlled to perform production based on all the optimized rates.

[0058] In some embodiments, the production rate of each node on the industrial production line is optimized and adjusted by all matching degrees and material buffers, and the optimized rate of each node can be achieved by the following steps: Initialize an optimized rate adjustment model; All matching degrees are used as initialization parameters of the optimization rate adjustment model; The material buffer zone is used as a constraint parameter in the optimization rate adjustment model; The production rate of each node on the industrial production line is adjusted according to the optimized rate adjustment model, and the optimized rate of each node is output.

[0059] It should be noted that the optimized rate in this application refers to the rate after the node production rate of the industrial production line is optimized during production, which can be used to control the production rate of the industrial production line; In addition, it should be noted that the optimization rate adjustment model uniformly adjusts the rates of all nodes on the entire production line, thereby optimizing the entire production line. Each matching degree reflects the adaptability or coordination of the corresponding node under different production rates. These matching degree data are used as the initial input parameters of the model to guide the initial search direction and optimization target of the model, and the capacity of the material buffer is used as the constraint condition of the optimization rate adjustment model. These constraints ensure that when adjusting the production rate, it will not cause excessive backlog or shortage of the material buffer, thereby ensuring the continuity and stability of production. In specific implementation, the optimization rate adjustment model is constructed based on the machine learning library, and the optimization rate model is trained by a cross-validation method combined with the historical production rate of the industrial production line, and all matching degrees and material buffers are used as input features of the optimization rate adjustment model, and the optimization rate of each node is used as the output feature of the optimization rate adjustment model. In other embodiments, other methods can also be used for determination, which is not limited here.
