Abstract

A method for converting an aircraft assembly process tree based on an MBOM tree structure disclosed by the present invention aims to provide a multi-dimensional MBOM conversion method based on an AOE network that occupies less system resources and has a high degree of sharing. The present invention is realized through the following technical solutions: build the manufacturing material list MBOM and the MBOM conversion adapter based on the AOE network diagram, and carry out the reconstruction of the MBOM assembly tree, edit the initial model of the MBOM tree structure and build the MBOM tree structure release model, and The EBOM / PBOM tree structure information that constitutes the product structure tree is stored in the database, and the topological sorting of the one-way acyclic graph is performed at the same time; then all paths in the AOE network graph are traversed, and the sum of the weights of each edge in the path is calculated to obtain The path with the largest sum of weights is generated with the final node as the root node, and the AOE network graph is converted into an MBOM multi-tree structure for sharing and calling by other related systems.

Description

technical field

[0001] The invention relates to a method for converting an aircraft assembly process tree relying on an MBOM tree structure, especially a method for converting a heterogeneously converted multi-dimensional MBOM from an AOE network to a tree structure. Background technique

[0002] In modern production management, directed graphs are often used to describe and analyze the planning and implementation process of a project. A project is often divided into multiple small sub-projects. These sub-projects are called activities. In a directed graph, if the vertex represents the event (Event), the directed edge represents the activity (Activity), and the weight on the edge represents the duration of the activity (Duration), such a graph is referred to as an AOE network (ActivityOnEdgeNetwork, with edges representing event network). If the directed graph G is a weighted graph, the vertices represent events, the directed edges represent activities, and the tokens repre...
