The solution of optimization problems of laser information-measuring systems and their information and measurement channels, including functional elements for multiplicative signals, structures and technical parameters on a vector of quality indicators presented in tactical-technical requirements using expenditure indicators, is one from the main components of the theory of construction of such systems. Purpose of the article. Development of a universal method for solving multidimensional problems of optimization of parameters of laser information-measuring systems, no matter how it depends on the form of communication functions. The article discloses a separable programming method for optimizing laser information-measuring systems. The developed method uses the existing methods of modern mathematical programming with a separable representation of value and represents the optimum in analytical form, which allows it to "link" individual blocks of optimization problems into a common (single) solution. The method solves such problems as: multidimensionality, convergence of results, simplicity (universality), construction of exchange curves, and so on. It can be applied to any optimization problem as one-functional and multifunctional LIMS as a whole, and their information and measuring channels separately (including their functional elements). Analytical expressions for calculations are presented.
