Congestion management in electricity markets is traditionally done using deterministic values of power system parameters considering a fixed network configuration. In this paper, a stochastic programming framework is proposed for congestion management considering the power system uncertainties. The uncertainty sources that are modeled in the proposed stochastic framework consist of contingencie...

Portfolio and risk management problems of power utilities may be modeled by multistage stochastic programs. These models use a set of scenarios and corresponding probabilities to model the multivariate random data process (electrical load, stream flows to hydro units, and fuel and electricity prices). For most practical problems the optimization problem that contains all possible scenarios is t...

Scenario planning is a widely accepted management tool for decision support activities. Scenario planning, development, organisation, analysis, and evaluation are generally quite complex processes. Systems that purport to support these processes are complex and difficult to use and do not fully support all phases of scenario management. Though traditional Decision Support Systems (DSS) provide ...

Scenarios are widely used to specify desired system behaviors, but analyzing and managing large collections of scenarios remain a challenge. Scenario networks facilitate scenario management and serve as a powerful basis for analyzing and validating collections of scenarios. In a scenario network, each scenario is connected to those that may follow it, either as part of a single sequence or conc...

Scenarios have proven effective for eliciting, describing and validating software requirements; however, scenario management continues to be a significant challenge to practitioners. One reason for this difficulty is that the number of possible relations among scenarios grows exponentially with the number of scenarios. If these relations are formalized, they can be more easily identified and su...

a trend of significant increase in municipal solid waste generation has been recorded worldwide. this has been found due to over population growth rate, industrialization, urbanization and economic growth. consumerism speed has been found very high covering around more then 50% of total population since last decade due to higher economic growth, which has ultimately resulted in increased solid ...

The management of breast cancer is perhaps the most controversial of all and has evolved a sea change over the years. Contrast enhanced MRI imaging is emerging as the most efficient imaging diagnostic tool. Newer approaches for the biopsy of inoperable breast cancer are aimed at obtaining diagnostically adequate tissue samples while minimizing invasiveness and the risk of complications. The reg...
