Derives a first order perturbation algorithm for the computation of mean values and (co-) variances of the transient temperature field in conduction heated materials with random field parameters. Considers both linear as well as non-linear heat conduction problems. The algorithm is advantageous in terms of computer time compared to the Monte Carlo method. The computer time can further be reduced by appropriate transformation of the random vectors resulting from the discretization of the random fields.
