From Figure 2 make note that the movement of information is a constant process. There is some slight variation. Random example occurred without control. So the researchers chose an appropriate smoothing method with data resembles the belonged. There is no trend and no season or a non-random events may foreseeable that prediction by smoothing a moving average method: the method of weighted moving average, and how to adjust. A simple exponential, 46 Researchers have taken consumption as of a period is 1 week to week 25 is used in forecasting demand for medical supplies until 26 weeks by smoothing method to predict both the 3 ways, and then select the number of time intervals (N) to consider providing error.Khlue Lotto prediction method for low and average method of weighted moving average. Best how to adjust successfully booked a simple exponential weighted selection smooth adjustment (α) that provides proof of bias. Performance comparison of mean absolute deviation (MAD) of the amount of time to consider moving average method. Amount of time considering how mobile average weighted and weighted value has been adjusted for smooth adjustment method, the Executive of the simple exponential. Are as follows:
