The analysis of stochastic loss networks has long been of interest in computer and communications networks and is becoming important in the areas of service and information systems. In traditional settings computing thewell-knownErlang formula for blocking probabilities in these systems becomes intractable for larger resource capacities. Using compound point processes to capture stochastic vari...

We investigate the link between resource revenues volatility and institutions. build a stochastic differential game with two players (conservatives vs. liberals) lobbying for changing institutions in their preferred directions. First, uncertainty surrounds dynamics of revenues. Second, power is asymmetric, conservatives’ being increasing show existence unique equilibrium set affine strategies. ...

resource limitation in zero time may cause to some profitable projects not to be selected in project selection problem, thus simultaneous project portfolio selection and scheduling problem has received significant attention. in this study, budget, investment costs and earnings are considered to be stochastic. the objectives are maximizing net present values of selected projects and minimizing v...

Based on the Extended Colored Stochastic Petri Nets (ECSPN), the workflow system was modeled and simulated. To improve described capacity of the traditional Petri nets, a model of the extended colored stochastic Petri nets is proposed, and then an instance is given to explain how to model workflow system with priority queuing and multi-instances. Through analysis of the simulation data of the m...

We present a novel approach to specification of dynamic systems. This approach, a stochastic extension of process algebra, facilitates quantitative, or performance, analysis, in addition to qualitative analysis. For unreliable systems this integrated approach encourages the investigation of the impact of functional characteristics on the performance of the system. Throughout the paper details o...
