Abstract

The invention relates to the field of aircraft assembly digital process design, in particular to a process layout generation method and a process layout design system. The process layout generation method comprises the following steps: establishing a three-dimensional visualized model library of a process layout based on basic data of the process layout; completing process layout in a three-dimensional virtual environment by utilizing a model in a model library according to the basic data and the container scheme; importing and editing simulation parameters of the process layout; based on theproduction line scheme, creating stations of the process layout and associating equipment and process information; performing a simulation experiment on the process layout based on the simulation parameters and the process information to obtain a simulation result of the process layout; evaluating the process layout based on the simulation result; and after the process layout passes the evaluation, storing the process layout. In this way, the reasonability of the process layout and the operation convenience during process layout generation are improved, and the accuracy and completeness of evaluation are improved.

Description

technical field [0001] The invention relates to the field of aircraft assembly digital process design, in particular to a process layout generation method and design system. Background technique [0002] Process layout is an important criterion factor that affects the competitiveness of enterprises and their products. A reasonable process layout can save a lot of material transportation costs and improve the efficiency of equipment use. However, the process layout of the workshop is different from the general geometric layout problem, and it is not a pure geometric constraint. In addition to space utilization, it is also necessary to consider the process flow of the production system and other qualitative / quantitative conditions, such as logistics frequency, interrelationships between operating units, and certain specific constraints. [0003] The production line is an organizational form that is equipped with various manufacturing resources required to produce a certain pr...
