Ideally a measurement device is both accurate and precise, with measurements all close to and tightly clustered around the true value. The accuracy and precision of a measurement process is usually established by repeatedly measuring some traceable reference standard.
The earliest reference to similar formula appears to be Armstrong (1985, p. 348) where it is called "adjusted MAPE " and is defined without the absolute values in denominator. It has been later discussed, modified and re-proposed by Flores (1986).

Diagnostic odds ratio. In medical testing with binary classification, the diagnostic odds ratio ( DOR) is a measure of the effectiveness of a diagnostic test. [1] It is defined as the ratio of the odds of the test being positive if the subject has a disease relative to the odds of the test being positive if the subject does not have the disease.
