This paper tries to construct a performance evaluation procedure for highwa
y buses with the financial ratio taken into consideration. First, a concept
ual framework is redeveloped, based on the one created by Fielding et al.,
to help form evaluation items and performance indicators involving both tra
nsport and finance aspects. Second, the total performance is divided into t
hree major kinds of efficiency-production, marketing, execution-according t
o the cycle of operation activities. Third, to overcome the problems of sma
ll sample size and unknown distribution of samples, the grey relation analy
sis is used to select the representative indicators, and the TOPSIS method
is used for the outranking of highway bus. In addition, a case study is con
ducted using four highway bus companies as example. The empirical result sh
ows that the performance evaluation for highway buses could become more com
prehensive if financial ratios are considered.
