Abstract

In this chapter, we adopt Six Sigma (SS) approach and reliability, availability, and maintainability (RAM) analysis in a plastic industry. We present a step-by-step application of the SS methodology for identifying and reducing the downtimes in the industry and examine the current operations management. Thus, failure and repair data are analyzed on the basis of statistical techniques. Histograms, box plots, and descriptive statistics on line-level failure data are conducted. The mathematical distribution parameters that best fit the fault data are calculated. Models for reliability, maintainability, failure rate, and repair rate have been established for the entire system. The models could be a useful tool for determining current conditions as well as forecasting the performance of improving the line's operations management policies.
