This paper addresses the prioritization problem of parameters for making consensus on the combination of risk-reducing plans. The existing method supports reducing times of adjustments by prioritizing parameters in descending order of the gaps in “preferences” of parameters among experts. However, the existing method can not prioritize the parameters correctly when the disagreement is caused by the...
Supplier selection is a multi-criteria decision making problem which includes both qualitative and quantitative factors. In order to select the best suppliers, it is necessary to make a trade-off between these tangible and intangible factors some of which may conflict. When business volume discounts exist, this problem becomes more complicated, in these circumstances, buyer should decide about two...
This work considers the resolution of the system of fuzzy Diophantine equations. The concept of level sets is adopted to convert this problem into a crisp (traditional) nonlinear integer program. It is shown that the system of fuzzy Diophantine equations with concave membership functions can be reduced to a regular convex integer programming problem. The p-th power Lagrangian method is introduced...
Day-ahead unit commitment (UC) solution methods seek to determine the status and output of all available generators. In a world with an increasing integration of renewable energy sources such as wind electric generators (WEG), the UC solution process must model and include WEGs too in the decision-making process. Power output of WEGs in a day-ahead decision-making process are usually modeled using...
