Opis

The practice of modeling is best learned by those armed with fundament al methodologies and exposed to a wide variety of modeling experience. Ideally, this experience could be obtained by working on actual model ing problems. But time constraints often make this difficult. Applied Mathematical Modeling provides a collection of models illustrating the power and richness of the mathematical sciences in supplying insight into the operation of important real-world systems. It fills a gap wit hin modeling texts, focusing on applications across a broad range of d isciplines.
