To design a ship operation system, factors which have an influence on the state of ship operation must be clear. This paper describes evaluation of factors, which have been derived from simulations using queuing theory. Structual elements of simulation model are mainly those of crew (number of crew, ability, lineup), job (hour, occurring interval, kind), hardware (reliability, redundancy), port attendance system, and so on. In consequence of 83 days simulations for a proposed operation system, the following conclusions are obtained. a) The factors, which have a great influence on the ship operation, are port attendance system, rationalization of office work of crew, reducing maintenance demands of refrigerate containers, etc. b) Some good effects on the system can be expected caused by rising reliability of hardware system, especially modernized manning ships. c) The influence of modernized manning crew's ability on the system is almost same as conventional one. d) To reduce utilization (crew's working time), great improvement of hardware system is required.
