Stochastic activity networks (SANs) are a powerful and flexible extension of Petri nets. These models can be used for the modeling and analysis of various kinds and different aspects of distributed real-time systems. Similar to other classical extensions of Petri nets, SANs have some limitations for modeling complex and largescale systems. In order to remove these limitations and provide some h...

In this research, we study the applicability of object-oriented modeling techniques to stochastic optimization. We propose a methodology that uses the UML to model stochastic optimization problems.

Because of random nature of many dependent variables in coastal engineering, treatment of effective parameters is generally associated with uncertainty. Numerical models are often used for dynamic analysis of complex structures, including mechanical systems. Furthermore, deterministic models are not sufficient for exact anticipation of structure’s dynamic response, but probabilistic models...

Historical records for rivers in Fars Province are inadequate in comparison with the design period of hydraulic structures. In this study, time series techniques are applied to the records of three Iranian rivers in the Fars Province in order to generate forecast values of the mean monthly river flows. The autoregressive models (AR), moving average models (MA) and autoregressive moving ave...
