Equation-free mechanistic ecosystem forecasting using empirical dynamic modeling.
It is well known that current equilibrium-based models fall short as predictive descriptions of natural ecosystems, and particularly of fisheries systems that exhibit nonlinear dynamics. For example, model parameters assumed to be fixed constants may actually vary in time, models may fit well to existing data but lack out-of-sample predictive skill, and key driving variables may be misidentifie...

15 صفحه اولEmpirical Dynamic Programming
We propose empirical dynamic programming algorithms for Markov decision processes (MDPs). In these algorithms, the exact expectation in the Bellman operator in classical value iteration is replaced by an empirical estimate to get ‘empirical value iteration’ (EVI). Policy evaluation and policy improvement in classical policy iteration are also replaced by simulation to get ‘empirical policy iter...
متن کاملDynamic Modeling of Economic System in Iran
The long term goal attaining of economic system management requires the establishment of a dynamic framework to integrate multiple perspectives. This article considers the problem of economic development in macro level. As economic systems are complex adaptive systems composed of numerous numbers of components of dynamic and multidimensional nature, dynamics method is applied in this research. ...
متن کاملModeling Dynamic Production Systems with Network Structure
This paper deals with the problem of optimizing two-stage structure decision making units (DMUs) where the activity and the performance of two-stage DMU in one period effect on its efficiency in the next period. To evaluate such systems the effect of activities in one period on ones in the next term must be considered. To do so, we propose a dynamic DEA approach to measure the performance of su...
