ABSTRACT:
BACKGROUND OF INVENTION
1. Field of the Invention
One aspect of the present invention generally relates to a computer-implemented system and method for improving manufacturing productivity of a manufacturing process and, more specifically, a system and method for improving manufacturing productivity by using a combination of six sigma and lean manufacturing.
2. Background Art
In today's manufacturing business environment, companies are focused on finding tools to effectively decrease costs and increase productivity in manufacturing.
Six Sigma is one such tool that offers a group of statistical analysis techniques for reducing process output variations so that plus or minus six sigmas (i.e., standard deviations) lie between the mean and nearest specified output limit. Six sigma uses the DMAIC approach for reducing process output variation. DMAIC is the abbreviation for “Define, Measure, Analyze, Improve, and Control”. Applied to the manufacturing setting, six sigma can be utilized to search for variations in manufacturing processes and detect the cause of such variations. Although six sigma is effective at identifying differences in manufacturing processes over time, it does not offer an entire solution for driving increased productivity for manufacturing companies.
Lean manufacturing is another tool used to drive manufacturing process improvements. Lean manufacturing is focused on eliminating waste in a manufacturing process. In general terms, lean manufacturing offers tools for studying a process for waste and implementing controls to reduce the waste. Although lean manufacturing is effective in identifying and reducing waste on a quantitative level, it does not offer analytical and quantitative tools for eliminating waste.
A method and system is desired that integrates aspects of six sigma and lean manufacturing to provide a unique analytical tool for improving manufacturing processes. This method and system should be able to quantitatively and qualitatively analyze manufacturing data to drive productivity improvements in the manufacturing environment. Additionally, this method and system should have the ability to be computer-implemented
