We examined the physical origin of the colour–magnitude relation of elliptical galaxies in clusters of galaxies in the hierarchical clustering scenario by using a semi-analytic model of galaxy formation. The semi-analytic model includes some physical processes connected with the galaxy formation, such as merging histories of dark haloes, gas cooling, star formation, supernova feedback, mergers ...

The influence of numerous factors determines and changes the daily behavior consumers. This paper aims to estimate rank weight cultural, social, personal, psychological that change buying habits individuals. research was conducted on a sample 559 respondents in Republic Croatia. Data from survey were used create hierarchical model structure. analytic hierarchy process (AHP), as decision-making ...

Abstract Reducing customer response time, lowering overall logistic costs, and raising service standards are all partly attributable to innovative methods for increasing order-picking efficiency. This paper focuses on the storage allocation issue determine optimal stock-keeping-unit (SKU) inventory level assignment problem place SKUs in most efficient locations. In this research, we describe a ...

Mathematical expressions exist in all kinds of documents. The automatic location , recognition, analysis and understanding of mathematical expressions are important. Recognition of mathematical expressions has been an attractive problem for the pattern recognition community. When we meet the mathematical expressions we can’t recognize them like the way of ordinary text recognitions. We are in u...

This paper considers team decision making in mechanical engineering design, and in particular for decisions based on hierarchical evaluation criteria. We develop the Analytic Hierarchy Process as appropriate for mechanical design teams, and demonstrate that the method is particularly well suited for design problems that involve hierarchical descriptions such as for precision machine tools. The ...
