Computer subsidiary product assembling sequence generation method

Abstract

The invention discloses a computer subsidiary product assembling sequence generation method, belonging to the computer aided manufacturing technical field; the method comprises the following steps: firstly based on a layering task net programming method, building a product assembling knowledge base structure; secondly, virtual assembling body binding process, namely, using the layering structure of the virtual assembling body and the connecting structure of components and parts as a guide, binding the real components and parts to the corresponding virtual components and parts of the virtual assembling body; and finally generating the bound product assembling sequence based on the virtual assembling body; wherein the product assembling knowledge base structure comprises four knowledge modules which are of components and parts collection, assembling body layering structure, task layering and task decomposition strategy. The generation method can cause the structure of the product assembling sequence planning knowledge base to become clearer and be easily understood, the layering design of the task and the decision of decomposition tragedy to be more methodic and pertinence, thus increasing the generative flexibility and efficiency of the product assembling sequence and promoting the application of the computer subsidiary product assembling sequence in the intelligent manufacturing field.

Description

A computer-aided product assembly sequence generation method technical field The invention belongs to the technical field of computer-aided manufacturing, and in particular relates to a method for generating a computer-aided product assembly sequence. Background technique Assembly is an important link in the product manufacturing process. The efficiency and quality of assembly have a great impact on the manufacturing cost and final quality of the product. Automatic generation of product assembly sequence (ASP) is one of the important tasks of computer-aided assembly planning (CAAP). Because the ASP problem is an NP-hard problem, the research on this technology is very active at home and abroad in recent years. Intelligent planning (AIP planning) is an important and active branch of artificial intelligence research, which aims to automatically or semi-automatically generate an action sequence that meets the requirements (called a plan or plan) in an intelligent way.
