Modeling and coordinated control of large interconnected multi-purpose reservoirs spread across a country is usually challenging. These systems are generally characterized by coupled water quantity and quality variables and multiple control objectives. Efficient control of these systems can be achieved through appropriate and accurate modeling of reservoir dynamics in tandem with an accurate weather...
Agent-based modeling is one of the popular tools for analyzing complex socio-technical systems. Because of the complex nature of such systems a systematic methodology is required to guide the modeling process. By studying the existing methodologies in MAS we distinguished four major differences between MAS and ABM regarding goals, system scale and diversity, level of system understanding and verification...
Socio-technical systems are characterized by the autonomy of the individual participants that however must be able to collaborate in complex, dynamic environments. The design and analysis of such systems requires models that balance control and autonomy. In this paper, we present a conceptual framework to integrate organizational and individual perspectives, such that agent-based models for simulation...
Efficient flood management requires accurate real time forecasts to allow early warnings, real time control of hydraulics structures or other actions. Commercially available computing tools typically use, for flow or level forecasting, hydraulic models derived from the numerical approximation of Saint-Venant equations. These tools need powerful computers, accurate knowledge of the riverbed topography...
In most real-world settings, a transportation plan requires modifications during execution. A thorough evaluation of transportation planning methods thus requires testing and comparison in a dynamic environment. We give conditions on a simulation environment that follow from this requirement, and propose a multi-agent simulator meeting these conditions. In addition, we propose a new measure that captures...
Cloud computing has become a popular high performance computing model to provide services over the Web. Meanwhile, enterprise cloud applications are attracting more research attention, which consists of a large scale of inter-connected computing nodes and virtualized computers distributed over multiple enterprise domains. Driven by the resource demand and less cooperation among applications, some...
Incorporating weather forecasts in the control of land surface water levels requires predicting the outcome of a control action. In Model-Predictive Control (MPC) such predictions are generated by a model of the water system. The actuators in this specific application typically cause discontinuities in this model. Avoiding complex solving techniques for such hybrid systems, this paper introduces an...
The regulatory environment is becoming increasingly challenging, dynamic and complex. Modern ICT heavily impacts and shapes governance activities in order to provide policy-makers with precise, trustful and up-to-date information on the field of their interest in a more efficient and effective way. Internet evolution in the last few years has shown that the concept of interconnected data has expanded...
From the current research review and defects of the present leakage prediction model analysis, a multivariate grey GM (0, N) (Multi-factor Grey Model) considering the water supply pressure, water supply volume and frequency of leakage was proposed, finally it was used to predict the leakage of water pipe network, the results showed that the precision of grey GM (0, N) model was greatly improved in...
Model Predictive Control (MPC) has received wide attention from both the academic and industrial societies, mainly in the chemical industries, and is fast gaining popularity in Electro-Mechanical industrial systems. Great success stories of applications of MPC to industrial systems have been reported. However, the model based nature of this control methodology raises numerous questions of robustness,...
