The internationalization of the markets, the consequent worldwide competition, and the increasing demand for high-quality but low-price products require from modern industries a massive use of industrial automation in order to meet their customers' needs and to be competitive. Because of this, modern industrial automation systems have achieved a high level of complexity that makes them almost intractable for humans. Next generation industrial automation systems tend to be even more complex, since these systems are expected to be very large, distributed, containing highly dynamic and adaptive behaviour, having a long lifetime, and involving complex timing constraints. There is a consensus that conventional techniques for developing complex real time applications are not able to deal with such a complexity, mainly due to their poor abstraction mechanisms. Therefore, new techniques are required. This talk presents the propose of an object-oriented technique for dealing with such complex real-time applications, which is called ADDORATA (A Distributed Object-Oriented Architecture for Real-Time Applications). The ADOORATA project focuses specially on problems related to the development of large and complex real time industrial automation systems (for example, production control systems, robot control, etc.). The task of developing modern real time systems cost-effectively, on time, fulfilling prescribed quality criteria, can only be satisfactorily met by applying apt system engineering approaches. All development phases, from requirements engineering through design, implementation, testing, until maintenance are covered within the ADOORATA project.
