Abstract :

Statistical process control helps in systematic reduction of variability in key quality characteristics of a product. Clean development mechanism (CDM) can act as an effective instrument for mitigating climate change by effectively reducing the emission of CO2 and other green house gases (GHG). In this paper, an innovative attempt has been made to apply some of the advanced and modified process control charts like CUSUM (Cumulative Sum) and Exponentially Weighted Moving Average (EWMA) control charts which can be effectively applied for quality monitoring of Ready Mixed Concrete (RMC). A proactive approach enabled to detect the causes leading to the variations associated with the production process at a much early stage of the process. This would result in prevention of unnecessary usage of more cement by the commercial RMC plants which would result in reduced emission. Also, reduction in emission of CO2 can be achieved by about 35% by the usage of more flyash in the concrete mix. Thus the cost of quality involved in bringing the process within control can also be minimized. These control charts can be used as daily / weekly monitoring tool, which can improve the efficiency of the production process. Case studies of commercial batching plants in two metro cities of an emerging economic nation in South Asia have been considered for this research work. It has been observed that, though both the charts are sensitive to small process shifts, CUSUM technique along with V-mask appear to be a better tool for quality monitoring of RMC.
