THE PRINCIPLE AND CONSTRUCTION OF CHARACTERISTIC ANALYSIS MODEL

This paper studies the general principle and the construction of characteristic analysis model including the criterion of setting up characteristic enalysis model which can produce the greatest degree of match for cells mailing the deduction of the algorithm of evaluating the largest eigenvalue of matrix and its eigenvector; the different calculation methods and their explantiens of weights of variables and the degree of match for cells; the selection of variables that constitute the models and the evaluation of binary form and ternary form; weighting variables from the study of the relationships between variables and the conditions of use of the unconstraint models that calculate the degree of match for cells according to the weights; setting up generalized models by means of cells that do not contain deposits and lastly, the possibility of predieting the reserves of ore-deposits by means of the methods of characteristic analysis
