Main means to cope with these new challenges are the approaches, methods and tools of industrial informatics, which are characterized by great diversity and versatility. This paper aims to provide an overview and analysis of some of the most successful achievements of the industrial informatics in the chemical industry sector in order to achieve better selection and development of combined approaches and scenarios enhancing the agility and efficiency in this sector. Keywords: Industrial informatics, chemical industry, architectures, modeling, control, software INTRODUCTION and innovations in the enterprises of chemical industry should strive to achieve the following goals: The chemical industry is a significant part of • Satisfaction of customer needs of a wide range European economy, producing a variety of intermediate of high quality products at lower prices and in smaller and final products including base, specialty and consumer quantities; chemicals and pharmaceuticals, with over 1.2 million • Reducing the time of the products to reach the employees in European Union. According to the KRMG market, which is related to shortening the time for their analysis of the future of European chemical industry design, manufacture and supply i.e. ensuring a shorter [1], in 2007, 12 of the 30 leading chemical companies life cycle of manufactured products; are headquartered in Europe and they produce 10 % of • Production of goods with lower costs and the sector output. This analysis shows also that the improved quality through continuous implementation European chemical industry is facing new challenges and use of new technologies into existing production that require decisive steps to fast reengineering and systems. restructuring of the chemical plants due to changes The above mentioned goals, briefly summarized imposed by the global competition. For example, the as producing the right product at the right quantity of study argues that in the coming years the restructuring right place and at the right time require a new type of or closure of 40 crackers will be required worldwide, production systems, implementing new forms of business 14 of which are located in Europe with 26 % from the organization and new strategies for designing new European production. It is claimed further that 10 of products, their production and control, enabling rapid 17 plants for ethylene glycol are doomed to design of new products, agile plant reconfiguration
