1. A method for determination of importance of attributes identified in a plurality of attribute importance models selected from a plurality of available attribute importance models, comprising: determining an ordered set of attributes group by applying the plurality of attribute importance models to the plurality of attributes, the ordered set of attributes group having a plurality of attributes with a ranked attribute sequence; determining a subset evaluator important attribute group by applying at least one subset evaluator attribute importance model, and at least one classifier to the plurality of attributes; creating a combined ranked attribute sequence by combining, in descending rank order, the ordered set of attributes group and the subset evaluator important attribute group according to one of a constrained model mode and a relaxed model mode; creating a normalized attribute importance array for each attribute in the combined ranked attribute sequence, the normalized importance array having a normalized weight; creating a tagged attributes set by tagging each attribute in the combined ranked attribute sequence with a partition number based on recursive partitioning of the plurality of attributes through a weight range of the normalized attribute importance array; determining a conditional maximum number of attributes from the tagged attributes set and the subset evaluator important attribute group; designating, as attributes for further consideration, the plurality of attributes in a highest two partitions of the tagged attributes set having a non-zero rank in the normalized attribute importance array and a next highest attribute in the tagged attributes set until the conditional maximum number of attributes is met; designating, as additional attributes for further consideration, each of the plurality of attributes in the subset evaluator important attribute group having a rank greater than zero and which are not designated as attributes for further consideration; creating boosted attributes by increasing a normalized weight of each attribute in the subset evaluator important attribute group which is also designated as an attribute for further consideration; creating an order of attributes according to the normalized weight for each respective attribute, from the boosted attributes, the attributes designated for further consideration that are not in the boosted attributes, and the additional attributes designated for further consideration that are not in the boosted attributes; generating an ordered attribute set for each attribute in one of the order of attributes and a modified order of attributes by ordering each occurrence of each attribute in each of the plurality of attribute importance models in a descending order according to a number of occurrences; producing a normalized global rank for each attribute in one of the order of attributes and the modified order of attributes by multiplying the number of occurrences of each attribute in one of the order of attributes and the modified order of attributes by a number of occurrences of each attribute in each ordered attribute set, an average of the normalized weight of each respective attribute from the normalized attribute importance array and the normalized weight of each attribute from the boosted attributes; generating one of a normalized ranking list and a modified normalized ranking list for each attribute in the normalized global rank using a computer processor; and adjusting drilling operations based on one of the normalized ranking list and the modified normalized ranking list.
