In order to offer the service information of high-quality, we should develop the software of high-Quality. We need the united estimate method, because existing developed quality measurements individually measure attributes using the different viewpoint. Therefor, this paper propose the model that able to include many method of measurements. Our model selects the ratio scales and calculates the relative significance of them by using rough logic. Then, in order to measure the quality of module, it integrates the significance of scales and the measured value of them by using fuzzy integral. Finally, we analyze the correlation between the existing scales with our measurement and validate our model through statistical technique.
