A Contribution to the Investigation of Algebraic Model Structures in Qualitative Space

Quantitative and qualitative models. Basic forms of qualitative space. Code and numerical patterns in qualitative space. Qualitative process models. Latent and contradicting models. Completeness and acceptability measure of qualitative models. Examples of qualitative models of production parameters of the oil well log, seismic signals from the oil deposits and laser welding process.Quacol algebra and possibilities of its extensions. Criteria for usage of specific algebraic operations. Comparison of model structures from the standpoint of accuracy, simplicity and solution stability. Conversion of qualitative models to its quantitative counterparts and determination of mean value and amplification factor of the quantitative model. Comparison of the interim step of the Medusa-T and Medusa-H algorithms. Numerical limits of circular qualitative models.
