Abstract

In the promotion of lean production, workshop sites are frequently plagued by poor operation processes, prominent operator fatigue, and mismatched human-machine coordination. Taking a machinery processing and assembly workshop as the research object, this paper adopts literature review and on-site tracking investigation. Supported with human factors engineering theories including biomechanics, cognitive load and operation motion analysis, hidden human factor defects in the existing operation processes are identified and diagnosed. On this basis, process optimization schemes are designed from the perspectives of motion simplification, workstation layout adjustment, operation task redistribution and auxiliary equipment deployment. After the implementation of optimization schemes, the risk of musculoskeletal injuries is controlled, invalid motions and operation fatigue are alleviated, and operation efficiency and operating comfort are both improved.
