Abstract :
In this paper we consider two different techniques in order to determine the optimal calibration interval: the intervals obtained using a mathematical model and those calculated with an iterative technique referred to as simple response method (SRM). We apply these methods to rubidium frequency standard data. We have chosen this example because the degradation of its calibration condition can be modelled by the use of a quite complex stochastic process called integrated Brownian motion (IBM) also of interest in other different contexts. Moreover the rubidium frequency standard is quite diffused in industrial calibration laboratories
