3-902734- 20-4, ISSN 1726-9679, Vienna, Austria DOI: 10.2507/29th.daaam.proceedings.022 Abstract Modern manufacturing systems are increasingly characterized by using of complex machines, tools and electronics components. Especially a proportion of electronics and software has increa sed steadily in recent years. Challenge of this progression is the complexity of manufacturing systems during designing, integ rating and operating. Based on a product lifecycle - PL- this article introduces an integrated method for system design, which supports engineering and management of safety/security for digital manufacturing systems. This method was practically established during a planning and implementation of digital manufacturing system at the university of applied sciences “Technikum Wien ”. The outcomes of this method – integrated safety and security (ISS) - ought to help the factory design ers, integrators and users for (re)designing , operating and maintaining of machines, robots as far work-cells . The future work is to build simple software tool to support small and medium-sized enterprises (SMEs) for decision ma king during evaluation of risk assessment and management. Keywords: functional safety; industrial security; production systems; product lifecycle manage ment 1. Introduction The great idea “Internet of Things (IoT) ” for real time connection of system components to the worldwide network enables not only advanced manufacturing features of production syste m but completely new business models too . New entrepreneurial concepts enables to open market much better competitiveness for medium-sized or small-scale production facilities. On the other hand , this worldwide connection of production system turns themselves into complex system structure and highlights the problem of information security. Th erefore industry sets very high and new requirements for the machines and production systems [1] as follows: 1. to be able to produce customized, complex but cost-effectively products in small batches, 2. to be (re)designed or adapted in ever shorter planning times and 3. to interact autonomously and self-organizing. - 0157 - 29TH DAAAM INTERNATIONAL SYMPOSIUM ON INTELLIGENT MANUFACTURING AND AUTOMATION To fulfil the first requirement, the smart production system must have a mong other hard- /software compatible interfaces, capable for the connectivity with other manufacturing seg ments. The new domain will be articulated through design of cyber-physical systems. This terminology is (in Europe) often associated with Industry 4.0, where the physical representation is enhanced, by using of a virtual technology to ultimately si mulate and plan the products in altered batches. In order to fulfil the second requirement, computer aided methodical app roaches, are mandatory. This part is the subject of this work and will be shortly explained above. The last requirement would be reached by establishing a secure communication between the components of the systems. For decision ma king an artificial intelligence must be established. While for the company owner, the technological progress and rentability of pr oduction systems are important foundations, for policy maker is the safety of employe es very important. Furthermore, the information security has a rocky relationship with safety machinery [2]. A quantitative relationship between these two important issues was shown in [3]. In Figure 1 you can see the integral method for the risk analysis. This method ex plains the integrated method for machine safety and security for one concept solution . That means usability of a given method limits only for the machine s (closed systems ) - and for system- integrators and -users, but not for system-d esigner, who among other must to take a decision by choosing/evaluating the best suitable solution from a possible conce pt. This work extends and elaborates “building bloc ks” as conceived in [3] for the lifecycle phases of (machines/ manufacturing) system . This uses the classic method of system design and adds the newly safet y and security requirements as an integral part of system design. Fig. 1 .
