PT. XYZ in Surabaya is engaged in the production of commercial ships, providing ship repair and maintenance services as well as general engineering with specifications based on orders. Along with the development of the technology industry, ship production requires every shipyard to evaluate the system used. The time delay is the problem of building a 60 meter commercial ship.
