Ramin Karim Luleå, November 2008 Page IV Abstract Abstract ,QWRGD\·VJOREDObusiness scenarios, an organization can strengthen its com- petitiveness by offering a spectrum of industrial services that range from tra- ditional customer support to turnkey solutions. To achieve this service spec- trum, it is necessary to manage information consumption and production at right quality level in right time. When dealing with complex technical sys- tems, e.g. military aircraft, with long life cycles, the management of mainte- nance-related information is crucial to fulfil stringent dependability, Life Support Cost (LSC) and safety requirements. Today, there is available Infor- mation & Communication Technology (ICT) to realize an eMaintenance solu- tion for the necessary information logistics. However, there is a lack of ap- propriate frameworks, methodologies and tools that enable a service-oriented approach to eMaintenance. Hence, the purpose of this research is to explore and describe how an eMain- tenance solution can be developed to provide information services that sup- port the maintenance of complex technical systems. To fulfil the purpose, a major case study within military aviation has been performed, supported by two minor case studies within the healthcare sector and the process industry. Empirical data has been collected through interviews, observations, archival records and workshops. The analysis is based on developed theoretical frameworks, Design of Experiment (DoE) principles and available interna- tional standards. The results of this research are: I) an exploration and definition of eMainte- nance; II) a description of eMaintenance as support to maintenance of com- plex technical systems; III) an eMaintenance Management Framework (eMMF) for establishment of an eMaintenance platform; and IV) a methodol- ogy with a supporting toolbox that facilitates the identification of mainte- nance support information. Keywords Maintenance Support Service, Complex Technical Industrial System, Service- Oriented Architecture, Information Logistics, eMaintenance. Page V Summary in Swedish Summary in Swedish (Sammanfattning) I dagens globala företagsklimat kan en organisation stärka sin konkurrens- kraft genom att erbjuda ett helt spektrum av industriella tjänster, allt från traditionellt kundstöd till färdiga nyckellösningar. För att uppnå ett sådant tjänstespektrum är det nödvändigt att kunna hantera konsumtion och pro- duktion av information på rätt kvalitetsnivå vid rätt tidpunkt. Vad gäller komplexa tekniska system, t. ex. militära flygplan, med lång livslängd är han- teringen av underhållsrelaterad information avgörande för att kunna uppnå hög driftsäkerhet, låga underhållskostnader (Life Support Cost, LSC) och ri- gorösa säkerhetskrav. Det finns idag Informations- och Kommunikationstek- nik (IKT) som möjliggör en eUnderhållslösning för den nödvändiga informa- tionslogistiken. Det saknas dock lämpliga ramverk, arbetssätt och verktyg som möjliggör en tjänsteinriktad ansats mot eUnderhåll. Följaktligen är syftet med denna forskning att undersöka och beskriva hur en lösning för eUnderhåll kan utvecklas så att den tillhandahåller informations- tjänster som stödjer underhållet av komplexa tekniska system. För att uppnå detta syfte har en stor fallstudie utförts inom militär luftfart, stöttad av två mindre fallstudier inom sjukvårdssektorn och processindustrin. Empiriska data har samlats in genom intervjuer, observationer, arkivstudier och semina- rier. Analysen baseras på utvecklade teoretiska ramverk, principer för stati- stiks försöksplanering (Design of Experiment, DoE) och tillgängliga interna- tionella standarder. Resultatet av denna forskning är: I) en utforskning och definition av eUnder- håll; II) en beskrivning av eUnderhåll som ett stöd för underhåll av komplexa tekniska system; III) ett ramverk för eUnderhållshantering (eMaintenance Management Framework, eMMF) i syfte att etablera en eUnderhållsplatt- form; och IV) ett arbetssätt med stöttande verktygslåda som underlättar iden- tifieringen av information som stöd till underhåll.

  • Realizing a Digital Enterprise Driven by Standards
    Realizing a Digital Enterprise driven by standards This document refers to the Digital Enterprise as a business that not only creates and uses digital representations of the products and environment in which it operates; but aspires to trace an entire digital thread of its products as digital twins through their product lifecycle. Standards are an axiom for common enterprise understanding and the longevity of the digital thread used in Siemens product lifecycle management (PLM) solutions. These standards-driven solutions cover a breadth of industries, including discrete manufacturing, construction, marine and energy. This document addresses standards used in Siemens products that are principally aimed at discrete manufacturing across a wide range of domains, including auto- motive, aerospace and consumer products.

  • A Meta-Model for Leveraging the ISA- 88/95/106 Standards
    A meta-model for leveraging the ISA- 88/95/106 standards Introduction The story began in 1990 with the ISA-88 « Batch control » standard that addresses modular automation for flexible batch processes. It was followed by the ISA-95 « Enterprise – control systems integration » standard that deals with manufacturing operations management (MOPM, MES) and interoperability. The latest ISA-106 “Procedural Automation for Continuous Process Operations” standard tackles procedural control for continuous processes. These standards provide good engineering practices for improving control design for industrial facilities. ISA-88 and ISA-95 are respectively published as international standards IEC61512 and ISO/IEC62264. These standards share genetic concepts due to their consanguinity: many experts have contributed in the three standardization committees, which originated in ISA88. Though their viewpoint, terminology and abstraction level sensibly differ, the way they handle structural and behavioural aspects is relatively consistent, allowing a quite straightforward retro engineering of their implied meta-model. The interest of extracting a common meta-model of these standards is two-fold: - It allows understanding the respective scope of each standard and their overlap. - It makes easier to consider interoperability in the broader architectural approach of enterprise transformation Despite its technical and specialized content, this article may be of interest even for people who are not fluent in the discussed standards, but who could appreciate
