Investigation of economic model under fuzzy quality control environments is proposed in this paper. The fuzzy concepts are applied for analysis of the Weibull Distribution. The goal of this article is to construct the economic model was combining Fuzzy Weibull Distribution with Integrated model (Statistical process control and Maintenance management). The genetic algorithm is a method to find optimal values of four variables that minimize the hourly cost. Finally, the membership function of hourly cost is calculated and centroid method is used to find the crisp mean total hourly cost.
