The paper deals with the mathematical modeling of transient temperature and thermal stress fields using data subject to uncertainties. We present the use of Multistage-Multigroup (M-M) technique, based on the Unified Least Squares Method (ULSM), coupled with the Finite Element Method (FEM) and employed for solving the nonlinear, ill-posed problem. There are many advantages to be gained from that approach. We can verify the accuracy of the model, achieve more probable, from statistical point of view, calculation results, and, what is genuinely useful, receive a detailed statistical measure of the mathematical model correctness. The application example of transient temperature and stress field estimation in the element of technological system is included.
