Abstract    The paper describes the usage of the fuzzy Mamdani analysis and Taguchi method to optimize the tourism satisfaction in Thailand. The fuzzy reasoning system is applied to pursue the relationships among the options of a tour company in order to be used in Taguchi experiments as the responses. In this research, tourism satisfaction is carried out using L18 Taguchi orthogonal arrays on parameters such as budget, duration, hotel-choices, travel-options inside the country and theme of the travel are analyzed for one output objective as satisfaction. The output of the fuzzy reasoning system is used as an input in the response of each experiment in Taguchi method. But, the improvement is used for the mean de-fuzzified output in the same experiment. The result is estimated using Taguchi-Fuzzy application and if companies focus on the selected options, it is most probable to achieve more than 90 percent of satisfaction.

در این مقاله با استفاده از روش فازی ممدانی و همچنین طراحی آزمایش¨های تاگوچی سطح رضایتمندی گردشگران بین¨المللی از کشور تایلند مورد ارزیابی قرار گرفته¨است. فاکتورهای تعیین شده برای رزرواسیون تورهای سیاحتی توسط متخصصین از: بودجه درنظر گرفته شده برای سفر، مدت اقامت، رتبه هتل(ستاره)، وسیله نقلیه در سفرهای بین شهری، نوع سفر(ماه عسل،دوستانه،گروه انبوه) تشکیل شده¨است. با استفاده از روش فازی ممدانی، فاکتور اول به شش طبقه و سایر فاکتورها هرکدام به سه طبقه فازی دسته بندی شده¨اند. با استفاده از نظر متخصصین، قوانین کلی برای رضایتمندی گردشگران درنظرگرفته شد. با تکیه بر این نظرات تخصصی، با درنظرگرفتن مدل سفر آن شخص و پارامترهای آن، که قطعا عددی غیرفازی است، نمونه¨ها در یک سیستم فازی بررسی می¨گردند. ازآنجائیکه خروجی¨های دیفازی شده تحلیل فازی ممدانی الزاما یکسان نخواهند بود، از نتایج حاصل میانگین¨گیری می-شود. (این متد تاکنون در هیچ یک ازتحقیقات گذشته در سطح بین¨الملل انجام نگرفته¨است، که این یک نوآوری در نوع خود است.) با استفاده از آرایه اورتوگنال L18، بطوریکه فاکتور اول دارای شش سطح و سایر فاکتورها سه¨سطحی می¨باشند، حاصل میانگین خروجی¨های دیفازی شده در سلول پاسخ آزمایش¨های تاگوچی وارد می¨گردد. پس از تحلیل توسط نرم¨افزار، سطحی که از هر فاکتور بیشترین مقدار نسبت سیگنال به اختلال را داشت، شناسایی می¨شود. در پایان با استفاده از پیش¨بینی تاگوچی، با قرار دادن سطوح بیرون کشیده شده از فاکتورها، نتایجی بدست می¨آید که قادر است سطح رضایتمندی توریسم را تا 90درصد افزایش دهد.
