Method of Optimum Placement of Noise Sourses and Elektromagnetic Field in Working Area

Abstract

A method of optimum placement of persistent noise sources in a working area is suggested. The method is also applicable to placement of sources of a constant electromagnetic field of microwave range. This method can be applied for the attestation and certification of workplaces. The paper considers a statement of the optimization problem of placing the sources, an algorithm and examples of its solution. This solution minimizes an adverse noise effect on people. The objective function and constraints are given. The method is based on random search (Monte Carlo method). In the course of the search a set of solution variants are generated that are based on the random values of the sources coordinates within the working area. Only that solution is retained by the search at which the objective function reaches minimum value and the given constrains are realized. The calculation results are evidence of the efficiency of the method proposed and possibility of minimizing the effect of the mentioned adverse factors on people.
