It is the first time to define the tolerance with upper deviation smaller than lower deviation as virtual tolerance which is given in this paper as well. Based on the concept of virtual tolerance, dimension chains of different assembly will simplify the analysis and calculation of fixing dimension chain which has compensator in probabilistic method, so that it is possible to calculate this sort of fixing dimension chain by probabilistic method.
