A model for organizational performance evaluation is proposed. Organizational performance support can reduce barriers to applications of multi-criteria decision-making procedures. The relevant criteria of the proposed model were derived from an expert group interview to include the analytic hierarchy process (AHP), which is performed to determine the weights of evaluation, and grey relational analysis (GRA), which is then performed to rank the organizational performance of the travel agency. The AHP is a measurement theory that prioritizes the hierarchy and consistency of judgmental data provided by a group of decision-makers. It incorporates the evaluations of all decision-makers into a final decision through pair-wise comparisons of the alternatives, without eliciting their utility functions on subjective and objective criteria. GRA examines the extent of connections between two digits through departing and scattering measurement methods. The combined AHP and GRA decision-making method can provide decision-makers with a valuable data analysis when evaluating organizational performance. Because the proposed model can inform organizational performance assessments, it is highly applicable to both academic and commercial organizational evaluation and development.

The thermal-economical optimization on a parallel dual pressure evaporation and two-stage regenerative organic Rankine cycle (DTRORC) using mixture working fluid is conducted in this study. The comparison between DTRORC and other ORC systems from the viewpoint of thermodynamic performance and economic performance is discussed. The effects of six key operation parameters on exergy efficiency and LEC are addressed. The bi-objective optimization for maximizing exergy efficiency and minimizing LEC are examined. The Pareto-optimal solutions using TOPSIS, LINMAP and Shannon&GRA decision-making methods are obtained and compared using offset factors. Results indicate that DTRORC obtains 1.75% higher thermal efficiency, 3.5% higher exergy efficiency and 1 kW higher net power than DORC, and 0.8% higher thermal efficiency, 2.5% higher exergy efficiency and 0.5 kW higher net power than DRORC. The optimal solution of the LINMAP decision-making method is chosen for mixture working fluids, while that for Pentane and R245fa are LINMAP and TOPSIS decision-making methods, respectively. From the viewpoint of Pareto-optimal solution, the exergy efficiency of R245fa/Pentane is 2.40% higher than that of Pentane and 1.39% higher than that of R245fa, while the LEC of R245fa/Pentane is 0.58% lower than that of Pentane and 3.42% higher than that of R245fa. • Thermo-economical optimization of DTRORC is conducted. • DTRORC obtains 0.8% higher thermal efficiency and 2.5% higher exergy efficiency than DRORC. • The optimal solution of the LINMAP decision-making method is chosen for mixture working fluids. • Exergy efficiency of R245fa/Pentane is 2.40% higher than that of Pentane and 1.39% higher than that of R245fa.
