Optimizing Production Operations at Pine Bluff Arsenal: A Comprehensive Ergonomic Analysis

This project, led by Dr. Steven L. Johnson, aims to enhance production efficiency at the Pine Bluff Arsenal through a thorough study of current operations. Key objectives include measuring production times, performing ergonomic analyses, and setting new time standards for all production lines. Utilizing simulation techniques, the project seeks to identify operational improvements. Detailed documentation and station-by-station analysis will provide insights into crew sizes and time management. The ultimate goal is to recommend work standards and methods improvements to enhance productivity and worker safety.
