A multi-criteria group decision-making method with fuzzy preference relations based on filtration-and-weighting-based triangular bounded consistency
In multi-criteria group decision-making (MCGDM) problems with incomplete fuzzy preference relations (FPRs), the consistency based on bounded rationality is preferred to depend on the historical preferences of decision makers to generate complete FPR matrices. There are two factors in influencing the effect of historical preferences on complete FPR matrices and further decision makers’ satisfaction of group solutions. One is the effectiveness of historical preferences and the other is their relative weights. On this basis, this paper proposes a new MCGDM method with FPRs based on the filtration-and-weighting-based triangular bounded consistency (FWBTBC), where historical FPRs between three adjacent pairs of alternatives are characterized by triangles and these two factors are considered comprehensively. A triangle filtration process is designed based on the Grubbs criterion to filter the abnormal triangles in the collected ones. A weight determination process is developed, where a distance measure between remaining triangles is constructed to calculate their weights. Based on the combination of the two processes, the FWBTBC of FPRs is created and then the proposed method is presented. The validity of the proposed method is demonstrated by its application in analyzing a drainage tube supplier selection problem for a tertiary hospital located in Hefei, Anhui, China.</p
Exergy Analysis and Heat Integration of a Coal-Based Oxy-combustion Power Plant
Oxy-combustion
is a competitive technology to enable the capture of CO<sub>2</sub> from coal-based power plants. The main challenge to implement this
technology is the large energy penalty and investment cost related
to CO<sub>2</sub> capture. A comprehensive exergy analysis has been
performed for an entire coal-based oxy-combustion power plant. The
exergy flows and irreversibilities are presented. The thermal efficiency
penalty related to CO<sub>2</sub> capture is about 9.4 percentage
points (on the basis of the higher heating value) and is mainly caused
by the air separation unit and the CO<sub>2</sub> compression and
purification unit. The theoretical minimum is 3.4 percentage points
when the two units are assumed to be reversible, where the air separation
unit contributes 1.4 percentage points and the CO<sub>2</sub> compression
and purification unit is responsible for 2.0 percentage points. The
compression processes are causing the largest exergy losses related
to CO<sub>2</sub> capture. The case studies show that the integration
of the compression heat with the steam cycle can increase the thermal
efficiency by up to 0.72 percentage points
