Zusammenfassung:The CUmulative SUM (CUSUM) control chart for a doubly truncated gamma distribution is developed by using the integral equation method given by Page (1954). The objective of this paper is to study the effect of truncation on average run length (ARL) of the CUSUM scheme for controlling the parameters when the variable characteristic is distributed as doubly truncated gamma distribution. An algorithm for estimating (ARL) is suggested and numerical results are provided. KEYWORDS: doubly-truncated gamma distribution; CUSUM; integral equation; average run length (ARL). MSC: 62P30 La carta de control CUmulative SUM (CUSUM) para una distribución gamma doblemente truncada es desarrollada usando el método de la ecuación integral de Page (1954). El objetivo de este paper es estudiar el efecto del truncamiento del largo promedio de la corrida (ARL) del esquema CUSUM para controlar los parámetros cuando la variable característica se distribuye gamma doblemente truncada. Un algoritmo para estimar (ARL) es sugerido y se proveen resultados numéricos PALABRAS CLAVE: distribución gamma doblemente truncada; CUSUM; ecuación integral; largo promedio de la corrida (ARL).
