Modelling of Decision-Making Process Relating to Design for Maintainability of Complex Technical Items

This paper deals with modelling issues of the decision-making process relating to design for maintainability of complex technical items. Especially, we presented the formal notation of a decision-making system, its elements and functions, and general description as well. Moreover, some application examples of design for the maintainability of such complex technical items as the ship power plants are presented. For development of the decision-making system, we applied a concept of the Mestrovic’s general system. Based on this system, we have worked out the computer-aided system called Maintainability Design System for ship power plants.
