Abstract
ارتباط بين سطح كارايي ويژگيها و رضايت عمومي از جمله آنهايي كه توسط مشتريان ابراز گرديده غالباً بكار برده شده تا اهميت سطح كارايي را در حالت قطعي محاسبه كنند. اخيراً روال كار بر اساس اصل گسترش استاندارد زاده با در نظر گرفتن ويژگي هاي تفكر انساني توسعه داده شده است.
مشكلات محاسبه از اهميت برخوردار بوده و تنها شباهت هاي نتايج تحليلي قابل حصول مي باشند. در اين مقاله يك روش دقيق وساده شده براي محاسبه ي اهميت مشتق شده از ويژگيهاي حالت داده اوليه توسط اعداد فازي مثلثي ارايه مي دهيم. محاسبه موثر بر اساس اصل TW – گسترش بوده ومنابع كامپيوتر قابل قبولي را بكار مي برد، حتي اگر تعداد زيادي از ويژگيها ومشتري در نظر گرفته شوند. روش مشتق شده پيشنهادي بعداً با روش هاي ديگر محاسبه اهميت فازي ويژگيها مقايسه شده است . نتايج يك بررسي نسبت به كيفيت خدمات هتل در Oradea (روماني) مشروط به كار برد روش پيشنهادي است .
Abstract
The correlation between the performance of attributes and the overall
satisfaction such as they are perceived by the customers is often used to
calculate the importance of attributes in the crisp case. Recently, the method
was extended, based on the standard Zadeh extension principle, to the fuzzy
case, taking into account the specificity of the human thinking. The
difficulties of calculation are important and only approximations of the
analytic results can be obtained. In the present paper we give a simplified
and exact method to compute the derived importance of the attributes in the
case of input data given by triangular fuzzy numbers. The effective
calculation is based on the $T_{W}$-extension principle and it uses reasonable
computer resources even if a large number of attributes and customers is
considered. The proposed derived method is later on compared with other
methods of calculation of the fuzzy importance of attributes. The results of
a survey with respect to the quality of hotel services in Oradea (Romania)
are subject to the application of the proposed method.
