The paper describes the methodology for calculating the cost of warranty obligations of products manufactured by a supplier that allows estimating a predicted repair cost over the period of warranty obligations and including it into the structure of a product’s price on the basis of the duration of the warranty obligations period. The cost calculation is performed for various types of warranty obligations with consideration of different stages of operation of a product. Generally, a product consists of constituent parts manufactured by a producer, and parts purchased from other manufacturers. Warranty periods for self-produced constituents and for purchased parts can either coincide or differ.

An analytical method has been presented for calculating average temperature differences for rectangular heat-releasing elements located in the body of a rectangular homogeneous thin heat-conducting plate relative to its edges with the same temperature. A stationary problem for the cases of heat removal from one, two, three, and four edges of such a plate has been considered.
