SPC implemented in two phases in two stages, first the analysis phase, the second is the monitoring phase. Control charts used in these two stages are referred Analysis control charts and control with control charts. The main purpose of the analysis phase is to: make the process in a steady state statistics; enough to make the process capability. Work to be carried out first analysis phase is the production of ready SPC origin, that is needed for the production process of raw materials, labor, equipment, measurement systems were prepared in accordance with standard requirements. Production can be carried out after the ready, attention must ensure that production is under influence of the elements produced no abnormal situation; then you can calculate the control limits for the production process of collecting data, and make analysis control charts, histograms, or process capability analysis, statistical test is in steady production process and process capability is adequate. If any one is not satisfied, then you must find out the reasons, to improve and re-prepare the production and analysis. Until two purposes of the analysis phase, it can declare the end of the analysis phase into SPC monitoring phase. The main work of the monitoring phase is to use the control using control charts to monitor. In this case the control chart control limits have been determined according to the results of the analysis phase, the data production process in time to draw to the control, and closely observe the principle of control chart SPC technology, fluctuations in the control point on the graph shows the process can be controlled or uncontrolled If found out of control, we must find the cause and eliminate its impact as soon as possible. SPC monitoring can fully reflect the role of prevention and control. In practice facility, for each control project must go through more than two phases, and will be repeated if necessary, so that from the analysis to monitor the process. Statistical Process Control SPC is short, the Chinese statistical process control. Use statistical methods to monitor the state of a process to determine the production process in a controlled state, to reduce product quality variations. Statistical process control (referred to as SPC) is a means of mathematical statistics process control tools. Its production process analysis and evaluation, according to the feedback information to detect signs of systemic factors that appear in what is SPC, and take measures to eliminate the effects SPC, so that the process is maintained at a controlled state only by the influence of random factors, in order to control quality purposes. It is believed that when the process is affected only by random factors, the process is in statistical control (referred to as a controlled state); when the presence of systemic factors influence the process, the process is in statistical control condition (referred to as out of control). Fluctuations due to the process of statistical regularity, when the process is controlled, process characteristics are generally subject to a random distribution of stable; and out of control, the process of distribution will change. SPC is the use of statistical process fluctuations regularity analyze process control. Thus, it emphasizes the process runs in a controlled and capable state, so that a stable product and service to meet customer requirements.
