The article analyzes the potential for improving rationing in the public procurement system to increase their transparency and efficiency. An original method of procurement rationing based on a matrix approach to management is proposed. The methodology includes a combination of mathematical methods, scenario and predictive methods, which allows us to take into account the alternative solutions in procurement management. The fundamental principle of applying the matrix approach in procurement is not to optimize the procedures within a specific order, not to save budget funds as such, but to increase the efficiency of procurement planning in order to implement the entire set of projects, taking into account the factors of time, the need for procurement for the customer and public interests.
