У статті запропоновано новий метод, заснований на гібридній нечіткій експертній системі, для оцінювання QoE веб-сервісів. Також показано, як різні параметри QoS впливають на QoE. Для цього було проведено суб’єктивний тест в контрольованому середовищі з реальними користувачами, щоб співвіднести параметри QoS з суб’єктивною оцінкою QoE. На основі результатів тесту отримано функції належності та правила для нечіткої системи. Функція належності отримана з використанням імовірнісного підходу, а правила виводу згенеровані за допомогою теорії нечітких множин. Оцінювання результатів проведено в середовищі моделювання за допомогою програмного комплексу MATLAB. Результати моделювання показують, що якість веб-сайту, оцінена та має високу кореляцію з суб’єктивною оцінкою якості, отриманою від учасників контрольного тестування.
