Выводы:

По результатам проделанной работы реализации экспертной системы в LEONARDO и PROLOG можно отметить, некоторые удобства и неудобства программ:

1) Неудобства переключения языка в программе LEONARDO, язык не переключается как в системе Windows, в отличие от PROLOG, как следствие увеличение времени на программирование ЭС в LEONARDO.

2) Неудобство в LEONADRO при создании экспертной системы, надо заполнять отдельно правила и объекты, что увеличивает время на создание экспертной системы, в отличие от этого в системе PROLOG достаточно написать тест программы руководствуясь нужными операторами.

3) Неудобства в программе PROLOG при выводе результатов на экран пользователю необходимо самому вводить ответ на вопрос, а в LEONARDO достаточно выбрать нужный ответ и нажать на ENTER.

4) Неудобства в программе LEONARDO при выводе результатов на экран и ответе на вопросы вы не видите вопросов, на которые уже ответили и ваших ответов, чтобы посмотреть при ошибке в каком вопрос вы не правильно ответили.
