Quality Evaluation Of Models And Polymodel Complexes: Subject-Object Approach

Abstract

New approach of models and multiple-models quality evaluation is proposed. This approachis based on twofold ideas. First, when selecting an object for modeling it is reasonable to select not a really existing (designed or abstract) object but a situation in progress, that includes the objects and the subjects of the modeling (people responsible for making decisions (DM), people responsible for the substantiation of a decision (solution), experts, and people responsible for the implementation of solutions. Second, the process of modeling is here assumed as a control process of developing situation under uncertain conditions, caused by absence of information needed for forming the substantiated decisions. The descriptive and formal statement of quality control of models and multiplemodel complexesare interpreted as problems of structural-functional synthesis of a model (a multiplemodel complex) and also, selection of optimal programs of control and regulation of structural dynamics of a situation in progress (quality control of models and multiple-model complexes).The example of solving the task of poly-model finding distances from a vertex to all other vertices of a graph is proposed.
