An assembly task planning method for complex products

Abstract

An assembly task planning method for complex products, including four steps of complexity source analysis, complexity classification description and measurement, establishment of assembly task planning model and algorithm optimization solution, the complexity source analysis is based on the complex assembly characteristics, and combined with information such as parts materials, processes, assembly resources, and production scale, to analyze the complexity sources of complex product assembly; the classification description and measurement of the complexity are from the complexity of product parts, assembly process, assembly resources, Classification and description of assembly complexity in terms of assembly operation complexity and other aspects, and based on the assembly process and assembly resources corresponding to different types of assembly parts and materials, etc. are specific categories or groups, the assembly process and assembly resources Operation selection and execution are non-independent correlations. For assembly operations under certain conditions, it is necessary to establish a measure of conditional entropy based on assembly conditions according to the corresponding conditions.

Description

technical field [0001] The patent of the invention relates to the field of product assembly line process planning, in particular to a complex product assembly task planning method. Background technique [0002] At present, for the assembly process planning and assembly task assignment of complex product assembly, most manufacturers have assembly planning based on sample assembly tests, which not only has a huge workload and takes a long time, but also the quality of process design is unstable, and the design results often vary from person to person. , it is difficult to achieve ideal results in the division and distribution of assembly tasks. In order to facilitate the realization of the digital factory and management requirements, the researchers applied the assembly task allocation oriented to the assembly line balance. Under the constraints of the assembly relationship constraints of product parts and components, combined with the actual resource constraints of assembly p...

Problems solved by technology

For complex assemblies, especially those that meet the needs of intelligent manufacturing and individualization, the diversity of assembly parts and the uncertainty of assembly increase, which increases the complexity of assembly operations and the error-prone rate of assembly, and the complexity of assembly The increased complexity is directly related to the ease of assembly and assembly time

Therefore, the existing assembly process planning and assembly task allocation technology has obvious limitations in the application of complex product assembly task planning
