Highly focused document retrieval in aerospace engineering : user interaction design and evaluation

Purpose – This paper seeks to describe the preliminary studies (on both users and data), the design and evaluation of the K-Search system for searching legacy documents in aerospace engineering. Real-world reports of jet engine maintenance challenge the current indexing practice, while real users’ tasks require retrieving the information in the proper context. K-Search is currently in use in Rolls-Royce plc and has evolved to include other tools for knowledge capture and management. Design/methodology/approach – Semantic Web techniques have been used to automatically extract information from the reports while maintaining the original context, allowing a more focused retrieval than with more traditional techniques. The paper combines semantic search with classical information retrieval to increase search effectiveness. An innovative user interface has been designed to take advantage of this hybrid search technique. The interface is designed to allow a flexible and personal approach to searching legacy data. Findings – The user evaluation showed that the system is effective and well received by users. It also shows that different people look at the same data in different ways and make different use of the same system depending on their individual needs, influenced by their job profile and personal attitude. Research limitations/implications – This study focuses on a specific case of an enterprise working in aerospace engineering. Although the findings are likely to be shared with other engineering domains (e.g. mechanical, electronic), the study does not expand the evaluation to different settings. Originality/value – The study shows how real context of use can provide new and unexpected challenges to researchers and how effective solutions can then be adopted and used in organizations.</p

Deliverable DJRA1.2. Solutions and protocols proposal for the network control, management and monitoring in a virtualized network context

This deliverable presents several research proposals for the FEDERICA network, in different subjects, such as monitoring, routing, signalling, resource discovery, and isolation. For each topic one or more possible solutions are elaborated, explaining the background, functioning and the implications of the proposed solutions.This deliverable goes further on the research aspects within FEDERICA. First of all the architecture of the control plane for the FEDERICA infrastructure will be defined. Several possibilities could be implemented, using the basic FEDERICA infrastructure as a starting point. The focus on this document is the intra-domain aspects of the control plane and their properties. Also some inter-domain aspects are addressed. The main objective of this deliverable is to lay great stress on creating and implementing the prototype/tool for the FEDERICA slice-oriented control system using the appropriate framework. This deliverable goes deeply into the definition of the containers between entities and their syntax, preparing this tool for the future implementation of any kind of algorithm related to the control plane, for both to apply UPB policies or to configure it by hand. We opt for an open solution despite the real time limitations that we could have (for instance, opening web services connexions or applying fast recovering mechanisms). The application being developed is the central element in the control plane, and additional features must be added to this application. This control plane, from the functionality point of view, is composed by several procedures that provide a reliable application and that include some mechanisms or algorithms to be able to discover and assign resources to the user. To achieve this, several topics must be researched in order to propose new protocols for the virtual infrastructure. The topics and necessary features covered in this document include resource discovery, resource allocation, signalling, routing, isolation and monitoring. All these topics must be researched in order to find a good solution for the FEDERICA network. Some of these algorithms have started to be analyzed and will be expanded in the next deliverable. Current standardization and existing solutions have been investigated in order to find a good solution for FEDERICA. Resource discovery is an important issue within the FEDERICA network, as manual resource discovery is no option, due to scalability requirement. Furthermore, no standardization exists, so knowledge must be obtained from related work. Ideally, the proposed solutions for these topics should not only be adequate specifically for this infrastructure, but could also be applied to other virtualized networks.Postprint (published version

Knowledge Based Systems: A Critical Survey of Major Concepts, Issues, and Techniques

This Working Paper Series entry presents a detailed survey of knowledge based systems. After being in a relatively dormant state for many years, only recently is Artificial Intelligence (AI) - that branch of computer science that attempts to have machines emulate intelligent behavior - accomplishing practical results. Most of these results can be attributed to the design and use of Knowledge-Based Systems, KBSs (or ecpert systems) - problem solving computer programs that can reach a level of performance comparable to that of a human expert in some specialized problem domain. These systems can act as a consultant for various requirements like medical diagnosis, military threat analysis, project risk assessment, etc. These systems possess knowledge to enable them to make intelligent desisions. They are, however, not meant to replace the human specialists in any particular domain. A critical survey of recent work in interactive KBSs is reported. A case study (MYCIN) of a KBS, a list of existing KBSs, and an introduction to the Japanese Fifth Generation Computer Project are provided as appendices. Finally, an extensive set of KBS-related references is provided at the end of the report

Integrated Project Support Study Group : findings

The challenges of the LHC project have lead CERN to produce a comprehensive set of project management tools covering engineering data management, project scheduling and costing, event management and document management. Each of these tools represents a significant and world-recognised advance in their respective domains. Reviewing the offering on the eve of LHC commissioning one can identify three major challenges: 1. How to integrate the tools to provide a uniform and integrated full-product lifecycle solution 2. How to evolve the functionality in certain areas to address weaknesses identified with our experience in constructing the LHC and integrate emerging industry best practices 3. How to coherently package the offering not just for future projects in CERN, but moreover in the context of providing a centre of excellence for worldwide collaboration in future HEP projects

Product lifecycle management in degree level teaching with Teamcenter PLM software

Despite the situation that product lifecycle management is heavily used in Finnish manufacturing industry, some Finnish educational institutions have not implemented practical PLM system functionalities into educational program. Common situation among educational institutions is that PLM training is mainly theoretical. Even when PLM software is implemented it is mainly used as data storage system. However, PLM system is much more than data storage. The lack of effective product lifecycle management training environment influences negatively to graduated students PLM skills. Increased communication, control of processes and single source of information are main benefits of a PLM system. This research studies the most relevant focus areas in Product lifecycle Management theoretical and practical teaching based on the requirements gathered from Finnish Manufacturing Industry. This research is focusing on the most important theoretical PLM focus areas, but also the most common practical PLM applications, processes and use cases in Finnish manufacturing industry. Based on the requirements of Finnish Manufacturing Industry, Teamcenter PLM software is implemented and configured to support practical degree level teaching. Research clarifies the current PLM knowledge of graduated students and gives recommendations about degree level PLM teaching arrangements. Both theoretical and practical teaching are considered. Based on the findings gathered from 35 Finnish manufacturing companies, relevant PLM use cases, processes and application are implemented to support Product Lifecycle management education with Teamcenter PLM software. Furthermore, the importance of different theoretical PLM topics is clarified based on the opinions of PLM professionals. This study utilizes design science research method to gather empirical data from different manufacturing companies. The foundation of PLM research presented in literature review provides the framework for this study. These studies provide the background information about PLM and how the implementation of PLM system can provide business benefits. This research proposes configured Teamcenter PLM environment for Finnish educational institutions to serve as a foundation of PLM system. Furthermore, the suggested PLM artifact is demonstrated, evaluated and communicated to specified target audience.Tuotteen elinkaaren hallinnan käyttö Suomalaisessa valmistavassa teollisuudessa on lisääntynyt viime vuosina merkittävästi. Käytön laajentumisesta huolimatta Suomen korkeakoulut eivät ole vielä täysin ottaneet käyttöön ohjelmistopohjaista käytännön opetusta. Yleinen tilanne on, että tuotteen elinkaaren hallintaa opetataan vain teoria tasolla, ja vaikka tuotetiedonhallinta ohjelmisto olisikin käyttöönotettu, se toimii pääasiassa datan tallennuspaikkana. Tuotteen elinkaaren hallinta ohjelmiston opetuksen puute vaikuttaa negatiivisesti valmistuvien opiskelijoiden PLM osaamiseen. PLM järjestelmän etuja ovat lisääntynyt kommunikaatio, kontrolloidut prosessit ja yhteinen tiedonlähde. Tämä tutkimus keskittyy löytämään merkityksellisimmät fokus alueet tuotteen elinkaaren hallinnan teoria opetuksessa ja käytännön opetuksessa. Tulokset perustuvat aineistoon joka on kerätty Suomalaisen valmistavan teollisuuden PLM asiantuntijoilta.
