The possibility of reducing logistic costs for transportation by solving the traveling salesman problem is considered. The algirythm for solving the problem using computational power of OpenOffice Calc's component "Solver" is suggested. On the basis of the proposed algorythm practical situatuion is solved and best route is formed. The conclusion about expediency of application of this method to solve practical problems is given.

The article describes the preparation of the sensitivity of the output voltage for a typical architecture of voltage reference to variations of the parameters of elements. Also considers the main advantages of this approach in the analysis and design of circuits. The article presents the corresponding graphs sensitivities. Based on the findings conclusions about the impact of deviations of circuit elements on the output parameters of the reference voltage was done.
