10 10 ad Knowledge: EU-Project IRIS [1] FAWCurrent Research Work Introduction  IRIS – Integrated European Industrial Risk Reduction System – Oct – Mar 2012, about 40 Partners, mainly form civil engineering domain, 4 partners from IT-Domain, one associated partner form Japan (University of Tokyo ) and US (Drexel University, Stanford University)  Motivation – Within Current practices in risk assessment and management for industrial systems are characterized by its methodical diversity and fragmented approaches. Integration is needed. – The large collaborative project IRIS is proposed to identify, quantify and mitigate existing and emerging risks to create societal cost-benefits, to increase industrial safety and to reduce impact on human health and environment.  Basic Concept – The basic concept is to focus on diverse industrial sector’s main safety problems as well as to transform its specific requirements into integrated and knowledge-based safety technologies, standards and services.  WP7: Monitoring, Assessment, Early Warning, Decision Support – FAW has its main task in this work package – setting up the decision support system.

12 12 Overall Goal – Find the early warning point (c) FAW – Johannes Kepler Universität | ad Knowledge: EU-Project IRIS [2] FAWCurrent Research Work

13 13 Decision Support System  Passive Decision Support – Providing the right information at the right time to the decision maker in order to support him/her. (i.e. via Data Warehouses or via good organized (good accessible/searchable) document bases  Active Decision Support – A system, that uses some AI (Artificial Intelligence) methods to elaborate a proposal to the decision maker or to do a decision autonomously. (data mining, neural networks, support vector machines, decision trees, case based reasoning,... ) -> Within IRIS we work in both directions – Active Decision Support -> Case Based Reasoning – Passive Decision Support -> Semantic Networks (c) FAW – Johannes Kepler Universität | ad Knowledge: EU-Project IRIS [3] FAWCurrent Research Work

14 14 Active Decision Support System  Case-based Decision Support (Example: Assessment of Simple Structures (Lamp Posts) Data – Design (Type, Height, Material,... ) – Measurement (Set of selected eigenfrequencies, vibration measured after a stimulation) – Visual Inspection (Condition of post and stand, Scratches, oxidation, condition of concrete) Task – Classification of lamp post’s condition (c) FAW – Johannes Kepler Universität | FAWCurrent Research Work ad Knowledge: EU-Project IRIS [4]

15 15 Active Decision Support System  Results – Currently case base consists of 800 measurements of different lamp posts – Above 90% “correct” classifications – Improvement of results: End-user can adjust parameters (attribute weights, predefined distances) – results are improving Identify and exclude “unrepresentative cases” (where connection (parameter values  classification result) is irreproducible) In some ways the inspection process could be adapted (e.g. less “free-text” attributes) In contrast to complex structures like e.g. bridges, an automated assessment of more simple structures, as lamp posts are, looks very promising (c) FAW – Johannes Kepler Universität | FAWCurrent Research Work ad Knowledge: EU-Project IRIS [5]

16 16 Passive Decision Support System  Combining Semantic Nets and Search Engines [1] (Example: VCDECIS) – This system builds a basic level of a wide scoped passive Decision Support System – Organization/management of an institution‘s content (documents) to enable easier retrieval of knowledge (c) FAW – Johannes Kepler Universität | FAWCurrent Research Work ad Knowledge: EU-Project IRIS [6]

17 17(c) FAW – Johannes Kepler Universität | FAWCurrent Research Work ad Knowledge: EU-Project IRIS [7] Passive Decision Support  Combining Semantic Nets and Search Engines [2] (Example: VCEDEIS ) Components – Search engine – Topic Map (3 layer), currently transferred to OWL – Web Portal Document upload platform Topic Map navigator incl. full-text search Content Topics Topics Content

18 18(c) FAW – Johannes Kepler Universität | FAWCurrent Research Work ad Knowledge: EU-Project IRIS [8]  Decentralized Approach – Each group can operate its own Knowledge Base (KB) and Decision Support Systems – IRIS Knowledge Base provides interface to partner KBs – Web Portal to access and administrate IRIS KB – Decision support (data assessment) mainly relies on local measurement data and on local background information (KB) – OWL will be the language Knowledge Representation (at higher level)

20 CBR-Cycle (Aamodt&Plaza1994): Case Base: General knowledge (knowledge base, e.g. models, reports, rules …) and already known cases Retrieve: Search – Retrieve the most similar case or cases Reuse: Adaptation – Reuse the information and knowledge in that case to solve the problem Revise: Verification – Revise the proposed solution Retain: Learn – Retain the parts of this experience likely to be useful for future problem solving Case Based Reasoning in General Case Based Decision Support [1] FAWEU-FP7-Project IRIS 20 | (c) FAW – Johannes Kepler Universität

22 General Statements on Cloud Computing Classical Computing Buy & Own: Hardware, System Software, Applications (often to meet peak needs) 5 Install, Configure, Test, Verify, Evaluate Manage:... Finally, use it €€€€€ - high Cost Cloud Computing  Subscribe  Use  € -pay for what you use, based on QoS (Quality of Service) every 18 Month? Long Term Vision ‘The IRIS Cloud’ [1] FAWEU-FP7-Project IRIS 22 | (c) FAW – Johannes Kepler Universität

23 General Statements on Cloud Computing Definition 1 A Cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualised computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements established through negotiation between the service provider and consumers. Cloud Services Software as a Service (e.g. Google Mail, … ) Platform as a Service (e.g. Google App Engine, Microsoft Azure, … ) Infrastructure as a Service (e.g. Amazon.com, … ) Ownership and Exposure Public/Internet Clouds (3 rd party Cloud Infrastructure and services, available on subscription basis) Private/Enterprise Clouds (Cloud runs within a company’s data center, for internal and/or partners use) Hybrid/Mixed Clouds (mixed usage of private and public clouds) 1 Rajkumar Buyya, Cloud Computing and Distributed Systems (CLOUDS) Lab, Dept. of Computer Science and Software Engineering, The University of Melbourne, Australia Long Term Vision ‘The IRIS Cloud’ [2] FAWEU-FP7-Project IRIS 23 | (c) FAW – Johannes Kepler Universität
