摘要：

In the paper, three-phase inverse Stefan problems are formulated and described by means of the optimization method. These problems consist in the reconstruction of the function which describes the coefficient of heat-transfer, when the positions of the moving solidus and liquidus interfaces are well-known. In numerical calculations the Nelder-Mead optimization method and the generalized alternating phase truncation method were used.
