Abstract: | Accuracy and interpretability have always been significant issues in forecasting
methods, and it is very important to have a balance between these issues when
developing a system in tourism demand forecasting.
There are various clustering algorithms used in many branches. The efficiency of the
clustering technique is stipulated by the performance of the clustering results. Fuzzy
c-means algorithm is highly efficient for unbiased clustering. In this thesis, fuzzy cmeans
algorithm is applied on monthly number of guest arrivals in one of the hotels
of North Cyprus over 40 months to find the optimal number of clusters in the analysis
problem. Also, the fuzzy rule-based system model for hotel occupancy forecasting is
developed, and in order to enhance the comprehensibility and accuracy of this model,
Mamdani fuzzy rule-based system is used.
Based on the values of root mean square error and mean absolute percentage error
which are metrics for measuring forecast accuracy, it is defined that the forecasting
model with 7 clusters and 4 inputs provides an optimal solution of the problem.

Do˘gruluk ve yorumlanabilirlik, ¨ong¨or¨ulme y¨ontemlerinde her zaman ¨onemli konular
olmus¸tur ve bu konular arasında dengeyi sa˘glamak, turizm talebinin ¨ong¨or¨ulmesi ic¸in
sistemin gelis¸tirilmesinde c¸ok ¨onemlidir.
Birc¸ok alanda kullanılan c¸es¸itli k¨umeleme algoritmaları mevcuttur. K¨umeleme
tekni˘ginin verimlili˘gi k¨umeleme sonuc¸larının performansı ile belirlenir. Bulanık
c-ortalama algoritması tarafsız k¨umeleme ic¸in y¨uksek verimlili˘ge sahiptir. Bu tezde,
bulanık c-ortalama algoritması, 40 ay boyunca Kuzey Kıbrıs’taki otellerden birine
gelen misafir sayısı ic¸in uygulanır ve bu algoritmanın amacı, analiz probleminde
k¨umelerin en uygun sayısını bulmaktır. Ayrıca, bulanık kural tabanlı sistem modeli,
otel doluluk oranını tahmin etmek ic¸in gelis¸tirilir ve bu modelin anlas¸ılırlı˘gını ve
do˘grulu˘gunu arttırmak ic¸in Mamdani kural tabanlı sistem kullanılır.
Tahmin do˘gruluk ¨olc¸ ¨um¨u ic¸in kullanılan ¨olc¸evler olan hataların ortalama kare k¨ok¨u ve
ortalama mutlak y¨uzde hatalarının de˘gerlerine dayanarak, 7 k¨umeli ve 4 giris¸li tahmin
modeli problemin en uygun c¸ ¨oz¨um¨un¨un sa˘glanmasını tanımlar.
