摘要： 产品的制造和装配效率与产品模块划分方案有关。为了进一步提高复杂产品的制造和装配效率，提出了一种新的产品模块划分和架构评价方法。首先，利用复杂产品已有的模块划分方案，建立产品各模块中零件间的相关度矩阵，将各相关度矩阵（子矩阵）组合到一起并添加模块间的相关度值，得到整个产品零件间的相关度矩阵；其次，基于信息熵理论，提出成本均衡度和复杂度均衡度的概念，并结合模块度、最小描述长度，通过熵权法算得各评价指标的权重，得到综合评价指标并对不同的模块划分方案进行评价；最后，以盾构螺旋输送机模块划分为例来验证所提出方法的合理性和可行性。通过盾构螺旋输送机已有的模块划分方案建立其零件间的相关度矩阵，利用层次聚类得到其不同的模块划分方案，并对其综合评价指标进行比较，从中选择一种最优的模块划分方案来表达盾构螺旋输送机的产品架构组成。基于模块度和均衡度的产品架构评价方法可以对复杂产品的架构进行有效、合理的评价，为提高复杂产品的制造和装配效率提供理论依据。
Abstract: The manufacturing and assembly efficiency of product is related to the product module division scheme. In order to further improve the manufacturing and assembly efficiency of complex product, a new product module division and architecture evaluation method was proposed. Firstly, using the existing module division scheme of complex product, the correlation matrix between parts in each module of the product was established, the correlation matrix (sub-matrix) was combined, and the correlation value between modules was added to obtain the correlation matrix between parts of the whole product; secondly, based on the information entropy theory, the concepts of cost equilibrium and complexity equilibrium were proposed. Combined with the modularity and minimum description length, the weight of each evaluation index was calculated by the entropy weight method, the comprehensive evaluation index was obtained, and different module division schemes were evaluated; finally, the rationality and feasibility of the proposed method were verified by taking the module division of shield screw conveyor as an example. Through the existing module division scheme of shield screw conveyor, the correlation matrix between its parts was established. Different module division schemes were obtained by hierarchical clustering, and their comprehensive evaluation indexes were compared, from which an optimal module division scheme was selected to express the product architecture composition of shield screw conveyor. The product architecture evaluation method based on modularity and equilibrium can effectively and reasonably evaluate the architecture of complex product, and provide a theoretical basis for improving the manufacturing and assembly efficiency of complex product.
