Fixed Variance Grouping:
This is the most useful for identifying the logistics cost implications of current or alternative operating practices. This method of formatting consists of assigning costs as either fixed or variable to approximate the magnitude of change in operating expenditure that will result from different volumes of logistical throughput. Costs that do not directly vary with volume are classified as fixed. In the short run, these expenses would remain if volume were reduced to zero. Costs influenced by volume are classified as variable. For example, the cost of a delivery truck is fixed, however gasoline to operate the truck is variable.
