Embodiment Construction

[0035] refer to figure 1 . According to the present invention, at first, based on the AOE network diagram, build the MBOM of the manufacturing bill of materials and carry out the reconstruction of the MBOM assembly tree and the MBOM conversion adapter and build the MBOM tree structure release model, edit the initial model of the MBOM tree structure, and convert the MBOM tree structure into the assembly process. AO, FO summary data and EBOM / PBOM tree structure information that constitute the product structure tree are stored in the database; in the AOE network diagram, each node of an aircraft assembly unit will be represented, and all nodes will be processed according to the first-in-first-out FIFO Perform topological sorting, the FIFO data buffer reads all nodes according to the topological sorting algorithm, records all its nodes as process plan WP, and stores its node information in the database; MBOM conversion adapter reads EBOM / PBOM in hierarchical order Tree structure...

Abstract

The invention discloses a method for converting an aircraft assembly process tree by means of an MBOM tree structure, and aims to provide a multi-dimensional MBOM conversion method based on an AOE network, wherein the multi-dimensional MBOM conversion method occupies few system resources and is high in sharing degree. The method is realized through the following technical scheme: constructing a manufacturing material list MBOM and an MBOM conversion adapter based on the AOE network diagram; reconstructing the MBOM assembly tree, editing an MBOM tree structure initial model, establishing an MBOM tree structure release model, storing EBOM/PBOM tree structure information forming a product structure tree in a database, and performing unidirectional acyclic graph topology sorting; and then traversing all paths in the AOE network graph, calculating the sum of weights of each side in the paths to obtain a path with the maximum sum of weights, and generating a path which takes a final node asa root node and converts the AOE network graph into an MBOM multi-way tree structure for other related systems to share and call.

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...
