Table 1 product assembly station configuration table
Due to differences in assembly processes of different products, module division of an assembly system cannot be performed through simple correlation analysis. The traditional division scheme is more directed to product modules, and a scientific and effective method and a tool are lacked for carrying out module division on an assembly system and an assembly process.
The invention provides an assembly system module dividing method for personalized customized products, which comprises the steps of firstly, aiming at the assembly process of mixed products, establishing an assembly process similarity matrix SMAP (similarity matrix of assembly processes) according to the assembly operation of the assembly process, the similarity relation between tooling equipment and parts and the process similarity of different products; fuzzy clustering is carried out on the assembly process similarity matrix by using a fuzzy clustering method to generate an assembly system module partition scheme set; and finally, realizing assembly line module division facing the personalized customized product by applying a comprehensive evaluation method and combining the characteristics of the assembly system module and flexible manufacturing requirements. The method comprises the following specific steps:
step 1: establishing an assembly process similarity matrix SMAP:
step 1.1: according to the similarity of assembly operation and assembly equipment among the product assembly processes, an assembly process operation similarity matrix SMAPP (similarity matrix of assembly processes) is established. The SMAPP matrix is a 20-row and 20-column matrix, wherein the ith row or ith column of the matrix represents an assembly process i, and a matrix element Pij∈[0,1]Shows the similarity of the process operation and the tooling equipment of the process i and the process j,nijnumber of similar operations, N, for Process i and Process jijRepresents the number of all operations of process i and process j; if the assembly operation and the tooling equipment are completely the same, the matrix element Pij=1。
As shown in fig. 1(1), the assembly process operation similarity matrix of the hybrid product is shown, taking process 1 (transmission shaft split charging) and process 2 (rear axle shaft split charging) as an example, the connection operation of the gear and the snap spring and the bearing are both completedThe press-fitting, basic assembly operations and the assembly equipment used are the same, so that the matrix element P is121 is ═ 1; and for the process 1 (assembling shafts of the gearbox) and the process 3 (assembling intermediate shafts and output shafts of the gearbox), the process 1 executes the installation operation of the gear and the snap spring and the press mounting of the bearing, and mainly comprises twice gear installation operation, twice snap spring installation operation and twice bearing press mounting operation, and the applied equipment is mainly a press mounting machine. While the process 3 executes two gear mounting operations, two shaft mounting operations and two bearing press-mounting operations, the applied equipment mainly comprises a press-mounting machine and a hoisting device, the number of the processes 1 and 3 is 12, and the similar operations only comprise 2 gear mounting operations and 2 bearing press-mounting operations, so that the matrix element P13=4/12≈0.3。
Step 1.2: and establishing an assembly process part similarity matrix SMAPC (similarity matrix of assembly processes components) according to the similarity between the assembly parts of the assembly process. The SMAPC matrix is a 20-row and 20-column matrix, the ith row or the ith column of the matrix represents the assembly process i, and the element C of the matrixij∈[0,1]Shows the similarity of the parts assembled by the process i and the process j,mijm is the number of similar parts in Process i and Process jijRepresenting the number of all parts of the process i and the process j; if the components are identical, the matrix element Cij=1。
As shown in fig. 1(2), referring to a process 1 (transmission shaft split charging) and a process 2 (rear axle shaft split charging), the process 1 performs transmission shaft split charging operation, the process 2 performs rear axle related shaft operation, and the assembled parts are basically different, so that a matrix element P is obtained12For process 1 (split charging of shafts of the gearbox) and process 3 (assembling of intermediate shaft and output shaft of the gearbox), process 1 needs to complete installation of 10 parts such as the intermediate shaft, the output shaft, three gears, two types of snap springs and two types of bearings, and process 3 executes installation of 11 parts such as the intermediate shaft, the output shaft, the three gears, the two types of snap springs and the three types of bearingsAnd comprises 10 parts performed by Process 1, so that the matrix elements P 1210/11 ≈ 0.9; and for the process 13 (hydraulic transfer case split charging), the process 14 (hydraulic transfer case leakage test) and the process 15 (hydraulic transfer case final assembly), the split charging, the leakage and the final assembly of the hydraulic transfer case are respectively completed, so the matrix element P12=1。
Step 1.3: according to the similarity of different product processes, a product assembly process similarity matrix SMPP (similarity matrix of products processes) is established. The SMPP matrix is a 20-row and 20-column matrix, the ith row or ith column of the matrix represents an assembly process i, and the matrix element Sij∈[0,1]Indicating the similarity of the process to different products,lijnumber, L, representing the product type comprising Process i and Process jijNumber representing all product categories; if the processes of different products are similar, the matrix element Sij is 1.
As shown in fig. 1(3), which is a product assembly process similarity matrix of the mixed product, process 1 (transmission shaft split) exists in all four products, so that a matrix element P exists121 is ═ 1; the process 13 (hydraulic transfer case split) is only present in both products (3, 4), so the matrix element P12=2/4=0.5。
Step 1.4: and determining the weight of each matrix by using an expert evaluation method aiming at the SMAPP matrix, the SMAPC matrix and the SMPP matrix, and constructing an assembly process similarity matrix SMAP.

SMAP=0.4×SMAPP+0.4×SMAPC+0.2×SMPP

TABLE 3 expert evaluation method
Step 2: fuzzy clustering is carried out to generate an assembly line module partition scheme set, and the method specifically comprises the following steps:
step 2.1: and constructing a fuzzy similar matrix by adopting an absolute value subtraction method-Euclidean distance based on the standardized matrix.
Step 2.2: and calculating a matrix transfer closure based on the fuzzy similar matrix, and converting the fuzzy similar matrix into a fuzzy equivalent matrix.
Step 2.3: and calculating a lambda truncation matrix of the fuzzy equivalent matrix, wherein lambda represents a classification coefficient for carrying out clustering analysis, and lambda belongs to [0,1 ].
Step 2.4: according to the lambda truncation matrix, assembly process modules are divided to construct an assembly module division scheme set, fig. 2 shows several feasible division schemes and corresponding lambda values, and the process division into an assembly module is shown in a frame.
And step 3: and comprehensively evaluating the assembly line module division scheme set, and selecting an optimal assembly line module division scheme.
Step 3.1: determining an assembly line division scheme evaluation index: the intra-module similarity refers to the similarity between the assembly operation and the assembly equipment in each divided assembly module and the assembled parts; the inter-module independence refers to the degree of difference between assembly operations between assembly modules, assembly equipment and assembled parts; the assembly complexity refers to the complexity of product assembly of the divided assembly modules. If the number of the divided modules is too large, the whole assembly process is complex, and meanwhile, if a plurality of processes are divided into one module, the assembly operation in the module is too complex, and the complexity degree of the whole assembly process is high; the module redundancy refers to judging whether the divided assembly modules can be combined or not, if the similarity degree of the two divided assembly modules is too high, the module combination can be carried out, and the module division scheme redundancy is high.
The indexes are evaluated by an expert evaluation method according to the table 2, the division weight of each evaluation index is determined, the evaluation of four experts is shown in the table 4, and the weight values in the case are all 0.25 through calculation.
TABLE 4 evaluation index expert evaluation method
Step 3.2: the division schemes of the assembly line modules are compared and evaluated according to the evaluation indexes, and satisfaction indexes of the schemes are determined according to the evaluation indexes, and a satisfaction degree measuring method of the evaluation indexes is shown in table 5. Taking λ ═ 0.787 as an example, as shown in fig. 2, the total number of modules is divided into 5, and processes 1 to 8 are divided into one module, so that the module redundancy is good, and the independence between the modules is good, but the intra-module processes 1, 3 and 6 have poor similarity, so that the intra-module similarity is poor; the complexity of the assembly operation in the same module is high, the complexity of the whole assembly process is high, and the evaluation results are shown in table 6. Other protocols were evaluated accordingly.
TABLE 5 evaluation index satisfaction
Step 3.3: the evaluation index weights are compared with each other, the assembly line module partition optimal plan is selected, and the evaluation result is shown in table 6, and it can be seen that the overall evaluation score is highest when λ is 0.851, and thus the evaluation plan is selected.
Table 6 partition plan evaluation table
This example combines the assembly processes according to their similarity relationships to form an assembly line module partitioning scheme {1, 2}, {3, 4, 5}, {6}, {7, 8}, {9, 10}, {11}, {12}, {13, 14, 15}, {16, 17, 18}, {19, 20}, which includes 10 subsets of modules, as shown in fig. 3.
