Abstract


The mathematical numerical methods can consistently serve the economical and managerial phenomena, including those dedicated to zootechnical and agricultural areas.
The paper fully turns to good account a series of numerical methods implemented on the computer toward the author, using it in the implementation of improvements of classical mathematical methods. The author has built his own algorithms, improved in terms of convergence of the implemented numerical methods. The mathematical numerical methods whose implementation is to be used in this paper refers to solving non-linear equations, non-algebraic (transcendent) equations, and also to solving non-linear systems of equations.
We point out the Cobb-Douglass nonlinear equation focused on throughout almost all the paper, through which the author wants to shape up economical issues in the field of Animal Husbandry and Agriculture. All the model-applications of the paper are based on Cobb-Douglas concepts – Cobb-Douglas equations and Cobb-Douglas non-linear sistems. These concepts are well presented in the works [23], [28], [30], [31], and [32]. See also any work of Econometrics from the Bibliography.
We must mention that the author is the owner of the computer implementation in an acknowledged programming environment, of all the methods listed above, and more. The implementation has been organized in an Integrated environment for numerical methods in mathematics and statistics. The mentioned integrated environment has been the object of a scientific research contract funded by the former Minister of Science and Technology (MCT), the contract drawn up between the parties: ITC (Institute of Technical and Scientifical Computer) Cluj-Napoca, and the mentioned ministry.
