The University of Houston (UH) Small Business Development Centers (SBD
Cs) were analyzed by Data Envelopment Analysis (DEA) and Assurance Reg
ion (AR) methods. The DEA/AR analyses were made for 11 DMUs in 1990 an
d 1991 and for 13 DMUs in 1992. The DEA ratio (CCR) method was applied
to Model I in all three years; unique optimal solutions to the DEA-in
efficient DMUs were verified. Also, ARs were applied to eliminate some
DEA-efficient DMUs requiring unreasonable multipliers to maximize eff
iciency. In addition, measures of returns-to-scale (RTS) intervals fro
m application of the DEA convex (BCC) method in 1992 showed several ad
ditional DEA-efficient DMUs needed some additional funds to work towar
d the most productive scale size.
