Data: Kao and Liu (2003).

Description

Data of 24 university libraries in Taiwan with one input and five outputs.

Usage

data("Kao_Liu_2003")

Format

Data frame with 24 rows and 11 columns. Definition of fuzzy inputs (X) and fuzzy outputs (Y):

x1 = Patronage

It is a weighted sum of the standardized scores of faculty, graduate students, undergraduate students, and extension students in the range of 0 and 1.

y1 = Collections

Books, serials, microforms, audiovisual works, and database.

y2 = Personnel

Classified staff, unclassified staff, and student assistants.

y3 = Expenditures

Capital expenditure, operating expenditure, and special expenditure.

y4 = Buildings

Area and seats

y5 = Services

Operating hours, attendance, circulation, communication channels, range of services, amount of services, etc.

beta3_l

lower spread vector Expenditures

beta3_u

upper spread vector Expenditures

beta5_l

lower spread vector Services

beta5_u

upper spread vector Services

Note

There are three observations that are missing: expenditures of Library 24 and services of Library 22 and Library 23. Kao and Liu (2000b) represent the expenditures of Library 24 by the triangular fuzzy number Y = (0.11; 0.41; 1.0). The services of Library 22 and Library 23 are expressed by a same triangular fuzzy number Y = (0.41; 0.69; 1.0).
