Muñoz Rosas, Juan Francisco Blanco Encomienda, Francisco Javier Proportion Type I Error Economic Plan Distribution function Many companies use the statistical tool named as statistical quality control, and which can have a high cost for the companies interested on these statistical tools. The evaluation of the quality of products and services is an important topic, but the reduction of the cost of the implantation of the statistical quality control also has important benefits for the companies. For this reaaon, it is important to implement a economic design for the various steps included into the statistical quality control. In this paper, we describe some relevant aspects related to the economic design of a quality control chart for the proportion of defecfive items. They are very important because the suggested issues can reduce the cost of implementing a quality control chart for the proportion of defective items. Note that the main purpose of this chart is to evaluate and control the proportion of defective items of a production process. 2025-07-16T07:31:15Z 2025-07-16T07:31:15Z 2016-04 image 2010-3778 https://hdl.handle.net/10481/105350 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional ICBEMS
