Sensitivity model of the set interdependent electrical, thermal and mechanical processes totality of electronic equipment to change of one of the internal parameters

In paper the authors consider creation of a sensitivity model for complex model of the interdependent electric, thermal and mechanical processes proceeding in an electronic equipment. The sensitivity model is formed by means of the principle of additional models creation. Use of complex model gives the chance to receive sensitivity functions of a process submodel variable of one physical nature to change of a process submodel parameter of other physical nature. It allows displaying actual parameters interrelation of heterogeneous physical processes within one design volume of electronic equipment.
