Model which states decline in extra time needed to produce last unit, every time for cumulative quantity of doubled units produced is classified as

Model which states decline in extra time needed to produce last unit, every time for cumulative quantity of doubled units produced is classified as incremental unit time learning model. Incremental unit-time learning model can be defined as Learning curve model in which the incremental unit time (the time needed to produce the last unit) is reduced by a constant percentage each time the cumulative quantity of units produced is doubled.
