Time is considered as production resource, which determines the need for its effective use in connection with other production resources. The problem consists in the inconsistency of the results of the existing forecasting system of production which are founded on modern concepts of space and time. The theoretical positions of Galilean, A. Lorentz and G. Minkowski were analyzed. A. Einstein’s explanations regarding the use of the velocity of light in vacuum as a constant in the well-known dependency for the generalized four-dimensional space were studied. An attempt is made to solve the applied problem in space and time, taking as a constant, for example, standard or maximum possible, (calculated) productivity.
