This article is devoted to an of solving vector optimization problems using modern technologies, namely, the possibilities of parallel programming. The most problems of economic activity are solved by methods of mathematical programming in this modern world. And most of them have a large dimension. The solution of this problems takes a lot of time even when using the powerful computing systems. The purpose of the article is to use all available logical cores of PC processor to solve problems, which will allow access to all the computing power of PC. Much attention is given to a more optimal algoritm for load disribution across thread, which allow to perform several independent actions. The method of solving vector optimization problems is reworked with the use of the algorithm. Thanks to this, it was possible to reduce the time of solving problems by 0.6n times, where n is the number of logical cores.
Keywords: vector optimization, economic activity, parallel programming, .NET, TPL library, main criterion method, sequential assignment method, target programming methods, multithreading
