  3. Cost distance analysis - Wikipedia

    en.wikipedia.org/wiki/Cost_distance_analysis

    The primary data set used in cost distance analysis is the cost raster, sometimes called the cost-of-passage surface, [9] the friction image, [8] the cost-rate field, or cost surface. In most implementations, this is a raster grid , in which the value of each cell represents the cost (i.e., expended resources, such as time, money, or energy) of ...

    Admitting that transportation costs are constant for all activities, this will lead to a situation where activities with the highest production costs are located near the marketplace, while those with low production costs are farther away. The concentric land-use structure thus generated closely resembles the urban model described above: CBD ...

  5. Diminishing returns - Wikipedia

    Similarly, if the third kilogram of seeds yields only a quarter ton, then the marginal cost equals per quarter ton or per ton, and the average cost is per 7/4 tons, or /7 per ton of output. Thus, diminishing marginal returns imply increasing marginal costs and increasing average costs. Cost is measured in terms of opportunity cost. In this case ...
