Additive Criteria to Evaluate Relevance of Innovative Objects in Data Warehouse

Abstract

The article discusses some aspects of warehousing object descriptions having significant innovation potential. The procedure for selecting such descriptions consists of two consecutive phases. The first phase involves generating effective search queries with a special genetic algorithm (GAP). In the second phase, the model developed determines the index of innovativeness of an object archetype. Meanwhile the values of additive selection criteria are calculated. In the former case, the criterion is a fitness function of GAP. In the latter case, the criterion is the index of innovativeness. The purpose of the article is to justify the additive criterion applicability for calculating the value of the GAP fitness function. The article describes general conditions of applying additive evaluation criteria and shows how these conditions are met for the GAP fitness function. The analysis of the partial criteria gives grounds to assert their additive independence and, therefore, the correct use of additive n-dimensional utility function. Some additional reasons for applying additive criterion are also given. In general, the article proposes a unified approach to generating global assessment criteria and the relevance of unified formal structure is shown. The models presented in the article are used to develop adequate computational algorithms for the developed data warehouse support system.
