Developing Control Measures to Reduce Variation in Weight of Packed Cement Bags

Summary: [This abstract is based on the author's abstract.]A variety of quality improvement tools are shown to help reduce variation in weight of cement bags. After the extent of nonconformance was confirmed, planned data were analyzed using analysis of variance techniques to identify possible sources of variation. The process capability was then estimated and the stochastic nature and economic factors of production were used to determine the optimum economic setting. Off-specification was reduced by 39 percent, leading to consistent production of a larger number of cement bags and increased customer satisfaction.
