Modelling On Lecturers’ Performance with Hotteling-Harmonic-Fuzzy 1ST H.A PARHUSIP, 2ND A. SETIAWAN Abstract. This paper is a brief research on modelling of lecturers' performance with modified Hotelling-Fuzzy. The observation data is considered to be as a fuzzy set which is obtained from students survey at Mathematics Department of Science Mathematics Faculty in SWCU in the year 2008-2009. The modified Hotelling relies on a harmonic mean instead of an arithmetic mean which is normally used in a literature. The used charaterization function is an exponential function which identifies the fuzziness. The result will be a general measurement of lecturers' performance. Based on the 4 variables used in the analysis (Utilizes content scope and sequence planning, Clearness of assignments and evaluations, Systematical in lecturing, and Encourages students attendance) we obtain that lecturers' performance are fair, poor, fair, and poor respectively. Keywords and Phrases : Hotelling, harmonic mean, fuzzy, exponential function, characteristic function.
