In statistical quality control, the EWMA chart (or exponentially weighted moving average chart) is a type of control chart used to monitor either variables or attributes-type data using the monitored business or industrial process's entire history of output. While other control charts treat rational subgroups of samples individually, the EWMA chart tracks the exponentially-weighted moving average of all prior sample means. EWMA weights samples in geometrically decreasing order so that the most recent samples are weighted most highly while the most distant samples contribute very little.Although the normal distribution is the basis of the EWMA chart, the chart is also relatively robust in the face of non-normally distributed quality characteristics. There is, however, an adaptation of the chart that accounts for quality characteristics that are better modeled by the Poisson distribution. The chart monitors only the process mean; monitoring the process variability requires the use of some other technique.The EWMA control chart requires a knowledgeable person to select two parameters before setup: * The first parameter is λ, the weight given to the most recent rational subgroup mean. λ must satisfy 0 < λ ≤ 1, but selecting the "right" value is a matter of personal preference and experience. One source recommends 0.05 ≤ λ ≤ 0.25, while another recommends 0.2 ≤ λ ≤ 0.3. * The second parameter is L, the multiple of the rational subgroup standard deviation that establishes the control limits. L is typically set at 3 to match other control charts, but it may be necessary to reduce L slightly for small values of λ.Instead of plotting rational subgroup averages directly, the EWMA chart computes successive observations zi by computing the rational subgroup average, * * * * * * * * x * ¯ * * * * * i * * * * * {\displaystyle {\bar {x}}_{i}} * , and then combining that new subgroup average with the running average of all preceding observations, zi - 1, using the specially–chosen weight, λ, as follows: * * * * * z * * i * * * = * λ * * * * * x * ¯ * * * * * i * * * + * * ( * * 1 * − * λ * * ) * * * z * * i * − * 1 * * * * * {\displaystyle z_{i}=\lambda {\bar {x}}_{i}+\left(1-\lambda \right)z_{i-1}} * .The control limits for this chart type are * * * * T * ± * L * * * S * * n * * * * * * ... |
