The hierarchical system of forest ecosystem models based on the theory of individual-based (structured) models of populations and communities is briefly described. New self-thinning models are integrated with tree stand models within a hierarchical system of models, aimed at assessing (quasi-) stable states of a forest ecosystem under given environment and management. Within the structural mode...

The rapid development of intelligent transportation system technologies and the policy emphasis on their deployment have increased the importance of predictive dynamic network flow models, especially so-called dynamic network loading and dynamic traffic assignment models. In this chapter we provide a critical review of analytic models used in predicting time-varying urban network flows. Specifi...

The process of managing libniries and networks of libraries is becoming more and more complex. This is partially due to the introduction of new technology and also due to an ever increasing quantity of published material to be processed and disseminated. In this ])apor, analytic tools are developed to help the decision maker resolve issues connected with storage and circulation policies. In the...
