Abstract

The invention provides a processing method and device for predicting aerospace product assembly hours. The processing method comprises the steps of creating a process classification library and a textcorpus; sequentially selecting pre-selection processes in the process card database, and obtaining a pre-selection process text and a pre-selection text corpus of the pre-selection processes; performing text mining on the pre-selected process text according to a pre-selected text corpus to obtain a pre-selected text feature vector; when determining that all the processes in the process card database have been traversed, training a man-hour calculation model corresponding to each process type, and storing the man-hour calculation model in a man-hour calculation model library; and obtaining a man-hour prediction value of the to-be-executed process according to the description text of the to-be-executed process and the man-hour calculation model library. According to the invention, the man-hour calculation model based on the process text features is constructed to carry out man-hour prediction, the problem that the current man-hour prediction is not suitable for aerospace products is solved, the accuracy and effectiveness of aerospace product assembly time prediction are ensured, and the production efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of man-hour prediction, in particular to a processing method and device for predicting assembly man-hours of aerospace products. Background technique [0002] Aerospace products (such as satellites, missiles, rockets, etc.) have the characteristics of complex systems, multidisciplinary integration, small batch production, and long development cycles. Assembly is the last link in the production of aerospace products and directly affects the final performance of the product. Working hour information is an important unit of measurement for enterprises to control costs, prepare production plans, and measure workers' labor. It is also a prerequisite and an important basis for enterprises to carry out production scheduling and planning and scheduling. With the increase of aerospace model tasks, the traditional assembly man-hour prediction method that relies on manual experience can no longer meet the accuracy and ...
