Groundwater remediation using the information gap decision theory

Proposing a linear model of energy hub operation using information gap decision theory

Energy hub is a concept relates various energy carriers which has been expanded in recent years. Operation of energy hub is often attended with uncertainties. Therefore, this paper presents a linear model based on information gap decision theory (IGDT) to solve the energy hub problem. This approach can consider plenty of uncertainties, simultaneously. Energy hub under study includes a combined ...

A practical approach to open-pit mine planning under price uncertainty using information gap decision theory

In the context of open-pit mine planning, uncertainties including commodity price would significantly affect the technical and financial aspects of mining projects. A mine planning that takes place regardless of the uncertainty in price just develops an optimized plan at the starting time of the mining operation. Given the price change over the life of mine, which is quite certain, optimality o...

Groundwater Remediation Strategy Using Global Optimization Algorithms

The remediation of groundwater contamination by pumping and injection is generally a long-term and costly strategy. Aquifer cleanup time is a highly nonlinear and nonconvex function of pumping rates. The cleanup objective often involves minimizing or constraining the cleanup time or cleanup cost. Linear programming and nonlinear optimization cannot guarantee the global solution. In this study, ...

Including severe uncertainty into environmentally benign life cycle design using information gap-decision theory

Business Intelligence Using Information Gap Decision Theory and Data Mining Approach in Competitive Bidding

Since the nineties, many electric utilities and power network companies have undergone and are still experiencing dynamic change in the ways of doing business, from a vertically integrated industry to an open market system. The operational planning activity of a generation company (GenCo) is no longer a cost-minimizing process, but seeks to maximize its net profit subject to physical constraint...
