Key process identification and clustering analysis method for multi-variety small-batch manufacturing process

Abstract

The invention relates to a key process identification and clustering analysis method for a multi-variety small-batch manufacturing process. The method comprises the following steps: S1, constructing amulti-variety small-batch quality key process identification model; s2, performing clustering analysis on the key processes of each variety based on a hierarchical clustering analysis method, furtherdetermining a selection scheme of resolution, expanding the sample size of the quality characteristic data, and solving the problem of insufficient quality characteristic data of the key processes; and S3, taking the manufacturing process flow of each variety of products of a certain aerospace complex component manufacturing enterprise as an example, and verifying the effectiveness and feasibility of the proposed model and method. According to the invention, key quality characteristics and influence factors involved in the key process are considered, quantitative analysis and calculation areperformed on the process criticality of the manufacturing process, identification of the key process is realized, and the key process is clustered and grouped. Accuracy, effectiveness and feasibilityare verified through program simulation and instance analysis, reference is provided for key process research, and support is provided for quality control.

Description

technical field [0001] The invention relates to a key process identification and cluster analysis method for multi-variety and small-batch manufacturing processes, which belongs to the field of quality control. Background technique [0002] Due to the increasingly diversified individual needs of users and the increasingly fierce market competition, the multi-variety and small-batch production mode has become an inevitable choice for global enterprises. However, its production characteristics such as many varieties and specifications, complex processes, small production batches and less repetitive production make it difficult to effectively control the quality of its manufacturing process. The key process is the key link in the quality control of the manufacturing process. Therefore, how to accurately and effectively identify the key process and how to solve the problem of insufficient quality characteristic data of the key process is the key to the quality control of the cur...
