Disposal of health-care waste (HCW) is considered as an important environmental problem especially in large cities. Multiple criteria decision making (MCDM) techniques are apt to deal with quantitative and qualitative considerations of the health-care waste management (HCWM) problems. This research proposes a fuzzy multi-criteria group decision making approach with a multilevel hierarchical str...

Data envelopment analysis (DEA) is a method to evaluate the relative efficiency of decision making units (DMUs). In this method, the issue has always been to determine a set of weights for each DMU which often caused many problems. Since the DEA models also have the multi-objective linear programming (MOLP) problems nature, a rational relationship can be established between MOLP and DEA problem...

In multi-criteria decision-making (MCDM) research, the criteria weights are crucial components that significantly impact results. Many researchers have proposed numerous methods to establish of criterion. This paper provides a modified technique, fuzzy method based on removal effects (MEREC) by modifying normalization technique and enhancing logarithm function used assess entire performance alt...

in traditional portfolio selection model coefficients often are certain and deterministic, but in real world these coefficients are probabilistic. so decision maker cannot estimate them exactly. financial optimization is one of the most attractive areas in decision under uncertainty. in the portfolio selection problem the decision maker considers simultaneously conflicting objectives such as ra...

Microgrid implementation often lacks economic and environmental efficiencies due to sub-optimal configuration operation. The current study aims explore the optimal operational strategies for a microgrid system with maximum life cycle co-benefits. This was inspired by real optimization need Shoals Marine Laboratory, seasonal marine teaching research field station on Appledore Island, Maine. A dy...
