Abstract: The problems of application software products for optimizing the costs of industrial enterprises in the health and safety of personnel are considered in the article. In last years, despite an increase in the cost of health and safety and the ongoing safety measures, the number of traumatic incidents, occupational diseases are not reduced. It necessitates to find ways to reduce costs while improving the level of pro-tection of the personnel of the enterprise. For this it is necessary to take measures for design of such new workplaces on which safety measures violation is excluded. But, not less important, on operating production for decrease in expenses for labor protection to carry out certification of all workplaces for identification among them with harmful or dangerous working conditions. Realization of these and other measures for improvement of labor protection, safety measures and optimization of expenses and improvement of management by these processes is impossible without ensuring automation of documenting and data processing about traumatism cases, workplaces with harmful working conditions, etc. For the solution of this problem need of use of software product «Certification» for optimization of expenses of the enterprise on personnel labor protection is proved.

Abstract: In the papera method of terminal control problem for dynamic systems with relay actuator solving is considered. Today, there is no general approach to solve the nonlinear dynamic systems control problem. Moreover, the specific type of control function and the fact that it is non-differentiable causes impossibility of using the classic techniques. The proposed approach is based on the reduction of terminal control problem to the extreme problem on the spaces of real variables and integers. For the reduced problem the modified hybrid evolutionary strategies algorithm has been designed. The new problem definition and the proposed algorithm were the basis for the designing general system of programming control for nonlinear dynamic systems seeking in the form of ideal or multilevel relay. The approbation of the investigated technique for satellite on the geostationary orbit control problem is considered.
