摘　　要：为了获得产品的最优自动装配顺序,根据自动装配原理提出装配零件集和装配约束件的概念,运用矩阵算法和线性递推算法构建装配顺序的WMS数学模型。依据产品装配结构特征和装配约束件约束特征分别构建装配关联矩阵和装配约束矩阵,进而获得理论装配工艺数和顺序序列。运用层次分析法确定装配因素的影响权重系数和对各影响因素值进行无量纲化处理,获得产品的装配顺序评价模型。运用此模型即可便捷地确定产品的最优自动装配顺序。以一自动-手动水龙头装配为例进行实证研究。结果表明上述理论方法可行和实用。In order to obtain the optimal automatic assembly sequence of the product, the concept of assembly parts and assembly restraints was proposed according to the principle of automatic assembly. And the WMS mathematical model of assembly sequence was constructed with matrix algorithm and linear recursive algorithm. In line with the characteristics of product assembly structure and assembly constraint, the assembly matrix and assembly constraint matrix were established respectively. The number of theoretical assembly processes and sequences, in turn, were obtained. The weight coefficients of assembly-influencing factors were determined by Analytic Hierarchy Process and the non-dimensionalization of each influencing factor was done for the realization of the evaluation model of assembly sequences. It is easy to determine the optimal automatic assembly sequence for the product with this model. The results, taking the automatic-manual faucet assembly as an example for the case study, show that the above theoretical method is feasible and practical.
