WebApr 4, 2024 · Weighting is assigned to sample points through the use of a weighting coefficient that controls how the weighting influence will drop off as the distance from new point increases. The greater the weighting coefficient, the less the effect points will have if they are far from the unknown point during the interpolation process. WebThe integrated weighting method combines subjective and objective weights that involve multiplication and additive synthesis (Zardari et al., 2015), where the principle is to integrate subjective weights based on opinion and objective weights that are mathematically processed information gathered from the criteria data.
