The paper deals with the numerical modelling of the unsteady temperature fields in the elements of technological systems using data subject to errors. The multistagemultigroup approach to numerical modelling of transient temperature fields is suggested. The internal structure of the matrix of coefficients of the set of constraint equations has been analyzed and simplifications in the adjustment procedure indicated. The method is easy to use in modelling of 2D and 3D transient problems. The efficiency of the presented algorithm enables us to estimate temperature fields using data subject to errors in on-line calculations.
