How to automate & schedule this Index optimization Script ?

Hi All SQL Experts,

How can I schedule this SQL script below to be executed once in a week for all my SQL Servers Database ?

-- Ensure a USE  statement has been executed first. 
SET nocount ON;

-- and convert object and index IDs to names.

If you have any other better script to rebuild index, please feel free to edit or suggest me instead.

Thanks,
