The frequent causes of ships’ detentions by port authorities are abnormalities of marine power plant functioning. Each extended ship lay time in port results in a waste of ship operating time thus costs rise to ship owners. This is connected with improper marine power plant management. In order to avoid this, a ship engineer should has system supporting his in the managing of the marine power plant at his disposal computer aided. Such a system can be worked out on the condition that a mathematical model, which represents the decision – making process of an engineer has been built. One element of the decision making process in managing the marine engine room is to determine how important is each of the tasks which the operators have to do. This estimation is the base to choose the most important tasks and make optimal schedule with them. The present work shows the approach to the rating method of operating tasks using AHP method. Based on practice, a hierarchic structure of factors influencing a tasks validity in the engine room operating process was made. Next, a preliminary questionnaire was conducted, which put questions to the experts as chief engineers next. This enabled to define numerical values of suitable coefficients influencing on the validity of operating tasks. The equation contains this all coefficients permit to determinate numerical values of an operating task’s validity in given engine room operating processes.
