Conference paper (peer-reviewed)abstract
- Today the providers of customer and product support related to military aircraft are facing major challenges. Traditionally, aircraft systems have stringent requirements on safety. In addition to this, the requirements on dependability, costs, and security have increased in importance. These changes, together with an increased diversity of customer requirements in a global utilization environment, add to the complexity of providing appropriate support solutions. The increased customer requirements have also lead to concepts such as total solution selling, or functional products, where the customers are offered availability performance to a fixed price. In order to enable efficient support solutions in a global support environment, e-Maintenance is seen as one important building block. e-Maintenance includes monitoring, collection, and distribution of realtime system health data and information to all stakeholders independent of organizational belonging or geographical location, 24 hours a day, 7 days a week (24-7). The concept of e-Maintenance is realized through the application of Information & Communication Technology (ICT), which integrates built-in tests, external tests at different maintenance echelons, and other sources of support information. The purpose of this paper is to describe important requirements and expectations that a provider of customer and product support related to military aircraft systems has on e-Maintenance in a global support environment.

Development of information support solutions for complex technical systems using eMaintenance
- 2009
-
Doctoral thesis (other academic/artistic)abstract
- Deployment and use of complex technical systems are common in society and in industry. Many of the complex technical systems have stringent requirements on safety, dependability and cost, which necessitate frequent updates and modification in response to new developments in technology and changing functional requirements. Hence, correct, role-adapted, situation-adapted, context-adapted and timely information and information support, is crucial to access, manage, maintain and improve the required services to be provided by these systems. Given the technological development and the changing business environment, system and support providers need to improve the design and provision of information support solutions. This can be facilitated by the utilisation of new and innovative Information & Communication Technology (ICT), manifested in emerging approaches such as eMaintenance. However, there is still a need of methodologies and tools that enable the development and provision of support information services by an integration of business and maintenance processes at both customers and providers to achieve novel business solutions such as Performance-Based Logistics (PBL) in the context described above.Hence, the purpose of this research is to describe how providers of support solutions can develop and provide effective information support solutions related to complex technical systems by enhanced utilisation of ICT. To fulfil this purpose, a single case study within military aviation was performed. Empirical data was collected through interviews, observations, archival records, workshops and action research. The analysis was based on existing, adapted and developed theories, model-based simulations and available international standards, considering an eMaintenance framework.The results of the research are: I) a definition of system-oriented, service-oriented, process-oriented and lifecycle oriented eMaintenance solutions; II) an identification of critical information and information support requirements of customers and providers while implementing e-maintenance; III) an identification of ICT-related methodologies and technologies suitable to fulfil the information support requirements of customers and providers; and IV) an approach for development and provision of ICT-based information support solutions that satisfy the requirements of customers and providers. Even though these results are achieved within the context of a modern military aircraft, the results throughout the research process indicate that they to a large extent are generic in nature and can be applicable to other complex technical systems within the process, power generation and transportation industries as well.

Journal article (peer-reviewed)abstract
- Maintenance and support providers to modern aircraft need to manage an increasing amount of information generated by growing system complexity and stakeholder requirements. This introduces new risks in the information management process and makes traditional information services and systems inadequate. However, recent advancements in information and communication technology (ICT) have contributed to the emerging approach of e-Maintenance, which forms an important building block to achieve the desired information logistics. e-Maintenance enables remote and real time maintenance, and includes; collection, monitoring, analysis and distribution of data and information as decision-support to stakeholders of the maintenance and support processes, independent of organization or geographical location, 24 hours a day and 7 days a week (24/7). This paper describes a proposed development of information products by linking theories to practical methodologies and tools (e.g., Quality Function Deployment, QFD) through the development of a demonstrator of a stakeholder-based information product in the context of a modern combat aircraft.

Development of user information products for complex technical systems
- 2004
-
Licentiate thesis (other academic/artistic)abstract
- Interaction with technological systems is an intrinsic part of daily life. The complexity of these man-made systems has reached unprecedented levels, and challenges the organizations that create and utilize them. At the same time they are often used in environments which imply very high requirements on safety, credibility, and reliability. Users of a complex system needs support to access and maintain the utility and services the system-of-interest or product, is to provide. Alongside more traditional support like service and maintenance, customer support also includes comprehensive documentation. Despite tremendous development of documentation for complex products, there is still a problem for users to access and understand the information. Development methods for user information products therefore need to be evolved.The purpose of this study is to explore and describe the development of stakeholder based information products for complex technical systems. The knowledge wanted is a model linking theory to real life applications, i.e. methodologies and tools that can support the development and continuous improvement of stakeholder based information products for complex technical systems. To fulfill the purpose a case study supported by a literature study has been made. The case study focused on a modern combat aircraft, which is considered as a highly complex system with stringent requirements on user information support. A development method for user information products was adapted and then applied and studied during the development of a demonstrator. The result of the study may be described in two parts. The first part is the identification of methodologies and tools for elicitation of requirements and user information development, from the area of cognitive science and joint systems of man-machine, quality technology and formal requirements management. The second part is the validation of the suggested way of working, tested through the development of the demonstrator. Compared to traditional development work the suggested way of working supplies increased stakeholder focus and a more efficient communication between developers and stakeholders, as well as within the development team. It also facilitates and improves requirements management and the possibility to reduce business risks connected to misinterpretations and disagreements over specifications.

Conference paper (peer-reviewed)abstract
- Today's providers of maintenance and in-service support related to modern aircraft are facing major challenges. A central problem with maintenance and support of aircraft and other complex technical systems is to manage the ever-increasing information flow and system complexity. Both military and commercial operators need to reduce downtime and one way to do this is to speed up the turnaround time for scheduled and unscheduled maintenance, or even better, to reduce the need thereof by implementing condition based maintenance. In order to implement these improved support solutions in a global support environment, eMaintenance is seen as one important building block. eMaintenance includes monitoring, collection, recording and distribution of real-time system health data, maintenance generated data as well as other decision and performance support to all stakeholders independent of organization or geographical location, 24 hours a day, 7 days a week (24/7). eMaintenance has the potential to improve the management and performance of activities related to the maintenance process, and thereby improve the dependability, safety and life cycle cost of critical systems. This is realized through the application of Information & Communication Technology (ICT) throughout the maintenance and support processes, thus integrating built-in tests, external tests at different maintenance echelons, technical information, diagnostics, prognostics and other sources of support information. The purpose of this paper is to present some results from a joint academic and aerospace industry research project, describing requirements and expectations that are important in a global support environment, and also to propose some central components in an eMaintenance framework that integrates maintenance and ICT perspectives.

Journal article (peer-reviewed)abstract
- Today‟s providers of maintenance and in-service support related to modern aircraft are facing major challenges. A central problem with Maintenance, Repair and Overhaul (MRO) as well as support of aircraft and other complex technical systems, is to manage the ever-increasing information flow and system complexity. Both military and commercial operators need to reduce aircraft downtime and maintenance man hours. Increased manual information management has the opposite effect, inducing unnecessary cost and affect efficiency negatively. Organisations developing and providing maintenance support products and in-service support does also need to improve the capability to efficiently exploit the increasing amount of digital product information and design data provided together with hardware (HW) and software (SW) products from aircraft manufacturers, sub-system suppliers and Original Equipment Manufacturers (OEM). One way to increase aircraft availability and improve maintenance and support efficiency, is to speed up the turnaround time for scheduled and unscheduled maintenance. The ultimate goal is risk-based utilisation and support, where true Condition-Based Maintenance (CBM) is integrated with current operational requirements and available resources in real-time. This aims at the elimination of all preventive scheduled maintenance based on fixed time intervals and execution of only corrective maintenance that has been predicted and turned into scheduled maintenance facilitated by proper support. To address the challenge of information logistics of digital product data and information within maintenance in-service support, providers need to adapt new methodologies and tools that enable full utilisation of the advantages of digital product data and information in processes and business models, e.g. Service-Oriented Architecture (SOA). In order to implement such improved support solutions in a global support environment, eMaintenance is seen as one important building block. eMaintenance includes monitoring, collection, recording and distribution of real-time system health data, maintenance generated data as well as other decision and performance support information to different stakeholders independent of organization or geographical location, 24 hours a day, 7 days a week (24/7). eMaintenance has the potential to improve the management and performance of activities related to the whole maintenance process, and thereby improve the dependability, safety and Life Cycle Cost (LCC) of critical systems. This can be realized through a coordinated application of Information & Communication Technology (ICT) throughout the maintenance and support processes, thus integrating Built-in Test (BIT) systems, external tests at different maintenance echelons, technical information, diagnostics, prognostics and other sources of support information. The purpose of this paper is to present some results from a joint academic and aerospace industry research project, describing requirements and expectations that are important in a global support environment, and also to propose some central components in an eMaintenance framework that integrates maintenance and ICT perspectives.

In: Journal of Quality in Maintenance Engineering. - : Emerald. - 1355-2511 .- 1758-7832. ; 15:2, s. 127-150
-
Journal article (peer-reviewed)abstract
- Purpose - The purpose of this paper is to describe a taxonomy for an eMaintenance management framework (eMMF) based on a service-oriented approach, in order to facilitate the development of information and communication technology (ICT)-based maintenance support services aimed at actors within the maintenance process related to complex technical industrial systems.Design/methodology/approach - To fulfil this purpose, a case study of a modern multi-role combat aircraft is selected as an appropriate research strategy and supported by a literature study. Empirical data are collected through interviews, workshops, document studies, and observations. A framework is developed and evaluated using a prototype within the studied case. The study is performed in close cooperation with the aircraft's type certificate holder and the customer representative and operator in one country.Findings - The proposed eMMF aids in the identification and development of ICT-based maintenance support services tailored for specific maintenance actors and their activities.Research limitations/implications - To further test the usefulness of the proposed framework, a larger scale application must be performed. This can involve additional stakeholders or a larger part of the technical system in the selected case, or another case dealing with complex technical industrial systems.Practical implications - The proposed framework supports the identification of required information services that support the maintenance process, which in turn supports the development of a service-oriented architecture (SOA) aimed at proper maintenance information logistics. Hence, people working with information logistics for maintenance purposes can use the framework as a support tool.Originality/value - The proposed framework combines a process and service-oriented approach, which facilitates the development of SOA-based information services by giving valuable input to more traditional system-oriented approaches.

The analysis was founded on theories related to maintenance and maintenance support. The conclusions of the study are corroborated by experiences from earlier software development and testing. FindingsMost existing contributions to the eMaintenance debate seem to suffer from too wide a gap between data processing and knowledge management. This tendency can be due to too great a focus on data collection, without any clear identification of the stakeholders‟ requirements. Hence, a mature eMaintenance solution should focus on the enhancement of service-oriented information logistics based on content sharing for an output-based information strategy.

Conference paper (peer-reviewed)abstract
- Achieving business excellence within industries which utilise complex technical systems requires effective and efficient maintenance. Maintenance is an important enabler of business performance. An effective maintenance strategy creates additional values in an organisation’s value-generating process. Establishing an effective and efficient maintenance process is highly dependent on supporting Information and Communication Technology (ICT) infrastructure for information logistics that facilitates maintenance decision support. eMaintenance solutions facilitates effective and efficient management and control of maintenance activities through an enhanced utilisation of computing; like;.estimation of their Remaining Useful Life (RUL); reduction of No-Fault Found (NFF); and prediction of fault. eMaintenance solutions enable a seamless integration and fusion of information services provided by information intensive systems with embedded components in order to manage increasing and extentensively distributed real‐time data collected via different data sources (e. g. sensors). Since, the emerging ‘Internet of Things’ is expecting to dramatically change information systems with inherent embedded components, eMaintenance solutions need to be adapted to this new context to fulfil the overall business requirements on an effective and efficient decision-making process; for e.g.: real‐time analysis based on real‐time data and context-aware information logistics. However, development and establishment of proper eMaintenance solutions can be facilitated through utilisation of appropriate framework which deals with real-world challenges. This paper explores some of the issues and challenges pertaining to eMaintenance industrial application.

Conference paper (peer-reviewed)abstract
- This work presents an approach for information exchange between adjacent air operations domains by means of graph technologies. The approach has the ability to leverage interoperability and collaboration between air- and ground-based systems and stakeholders in respective domains. In its foundation, it provides a means for relevant actors to access and assess relevant data, information and knowledge, and thus provide input in terms of viable action alternatives in a complex and dynamic operational context. As a proof-of-concept, we have utilizeda full-stack application framework to implement a decision support demonstrator for operational aircraft maintenance. Our solution facilitates a lightweight and dynamic representation of relevant domain knowledge,readily available for exploitation by graph algorithms, adapted to our domain. We have based our implementation on the full-stack application framework Grand-Stack, which is an architecture designed to exploit the power of graphs throughout its stack.

-
Conference paper (peer-reviewed)abstract
- In military aviation, Technical Publications (TP) are fundamental for the establishment of a maintenance strategy and provisioning of information support and maintenance services. They are also under the supervision of military authorities. For complex technical systems such as aircraft, technical publications often contain essential information such as indenture levels, repair and replacement instructions, spare part information, configuration information, required tools and item-related maintenance information. The manufacturer is faced with the challenge of coordinating the production of the complete TP-package. Authors and illustrators must write, draw and supply meta-data to every piece of information. They must do so according to detailed specifications (e.g. ASD S1000D) and writing guides. There is also complex cross-reference handling within the TP-package to consider, e.g. from maintenance instructions to illustrated parts catalogues. Cross-references exist within the content in the same publication, to other publications and/or to external information sources, e.g. databases. The information contained in the final TP-package is equivalent to, literally, tens of thousands of A4-pages. Paper-based deliveries, when occurring, are in themselves a logistic feat. The need for context-based adaptation of this complex information content to different actors' requirements is also challenging and need to be considered when establishing an efficient information logistic solution for provision of TP. Hence, the purpose of this paper is to provide an overview of some of the challenges and issues for establishing development and provisioning of Interactive Electronic Technical Publications (IETP[1]). Some important aspects and requirements on integration of IETP for both provider and user are also highlighted. The scope of the overview is restricted to an eMaintenance context related to military aviation.

Conference paper (peer-reviewed)abstract
- Interaction with technological systems is an intrinsic part of daily life. The complexity of these man-made systems has reached unprecedented levels, and challenges the organizations that develop and utilize them. Simultaneously, they are often used in environments that imply very high requirements on safety, credibility, and reliability. Hence, users of complex systems need information support to access and maintain the utility and services that the system-of-interest is to provide. Examples of solutions for this are Built-in Test (BIT) and Condition Monitoring (CM) systems aimed at increased maintainability performance of technical systems. However, despite these solutions there are still drawbacks manifested by No Fault Found (NFF) and Dead-on-Arrival (DoA) events, which may erode any benefits that BIT and CM systems may provide. Hence, in spite of tremendous development of information services for complex systems, there is still a problem for users to access and understand the information. Therefore, the development of maintenance support information services need to be evolved. This paper describes a service-oriented approach to CM as support to maintenance of complex technical systems. The service-oriented CM can be integrated in an information logistics solution through the utilization of new and innovative Information & Communication Technology (ICT). The proposed approach is illustrated in the context of modern aircraft.

Design of experiment and simulation for identification of significant e-maintenance services
- 2011
-
In: International Journal of Performability Engineering. - 0973-1318. ; 7:1, s. 77-90
-
Journal article (peer-reviewed)abstract
- The purpose of this paper is to present a methodology and a supporting toolbox that identify information-based maintenance support services using an evaluation of the services' impacts on the effectiveness of complex technical systems. A hypothetical aircraft and its support system are simulated in SIMLOX. The variables included in the model, as well as their expected effects on critical measures of system-effectiveness, were identified through interviews and studies of documents and the literature. The simulations have been planned and analysed according to established Design of Experiment (DoE) principles supported by MATLAB. Microsoft Access and Microsoft Visual Studio.NET has been used to integrate SIMLOX and MATLAB. The outcome of the study was scrutinised by both practitioners and statisticians. The methodology and its toolbox are useful for those involved in simulation work or the development of information services that support maintenance activities. The proposed systematic methodology, along with its supporting toolbox, identifies information-based services that are currently lacking when applying a Service-Oriented Architecture (SOA) approach during design and are considered valuable in identifying information-based maintenance support services within an eMaintenance solution

Safety and security in eMaintenance: The need for integration
- 2015

In: International Journal of COMADEM. - : COMADEM International. - 1363-7681. ; 18:2, s. 39-51
-
Journal article (peer-reviewed)abstract
- eMaintenance provides many new possibilities and opportunities to increase the productivity of industrial systems, yet decrease resources and administrative costs. To accomplish this though, it is often required to rely on some network connectivity with the system of interest. It is this network connectivity capability that runs the risk of being interdicted, thereby providing a window of opportunity, commonly referred to as a vulnerability, for a threat to exploit. This in itself is not necessarily new, but the applicability to eMaintenance is not well understood. To this end, this article answers the question of whether or not the integration of safety and security is of value to the eMaintenance domain by first providing a number of comparisons and contrasts between safety and security. This article then also introduces a pragmatic way to integrate safety and security called the harmonized protection conceptualization, which helps to assist with visualizing and organizing safety and security measures relative to a product/system design. As such, this conceptualization is used to assist with the final conclusions as to whether or not the integration of safety and security is a viable and necessary consideration within the eMaintenance domain. Besides addressing the question of the practicality and usefulness of integrating safety and security, this article will also address past research and noteworthy projects that have previously attempted this endeavour. Some general safety and security aspects of eMaintenance will also be addressed.

Conference paper (other academic/artistic)abstract
- With the advent of eMaintenance, there have been many newpossibilities and opportunities to increase the productivity ofindustrial systems, yet decrease resources and administrativecosts. To accomplish this though, it is often required to rely onsome network connectivity with the system of interest. It is thisnetwork connectivity capability that runs the risk of beinginterdicted, thereby providing a window of opportunity,commonly referred to as vulnerability, for a threat to exploit.This exploitation can occur in the form of a network securitythreat, information technology (IT) security threat, orinformation assurance and security threat. This in itself is notnecessarily new, but the applicability to eMaintenance is notwell understood. To gain a better understanding of thissignificance, there potentially needs to be a betterconceptualization of how to integrate safety and security at ananalytical level focused on the product or system designrequirements. To accomplish this, the first question that needsto be addressed is whether or not it is practical, or even useful,to pursue the idea of integrating safety and security for thesupport and protection of eMaintenance solutions? If the answerto this is yes, then what type of integration would berecommended? If the answer to the first question is no, thenwhy?There have been a number of comparisons and contrastsbetween safety and security over the last couple of decades. Inthe end though there still has not been a viable proposedconceptualization that can be utilized to integrate differentperspectives and practices in the safety and security domains.Today the most likely, although not the only, method to accountfor the integration of both domains is to conduct a safetyanalysis of a product or system of interest first and thenafterward, conduct a security analysis, or vice versa. Thismethod of development leaves much to be desired, and does notconsider the potential overlap of similarities between safety andsecurity. Nor does this method take into consideration that theinherent differences between the safety and security domainsare significant to the preservation of the original analyticalstrengths of both domains.Besides addressing the question of the practicality andusefulness of integrating safety and security, this paper will alsoaddress past research and noteworthy projects that havepreviously attempted this endeavour. Some general safety andsecurity aspects of eMaintenance will also be addressed.

Digitalization of Railway Maintenance : A Situation Awareness Perspective
- 2021
-
In: International Conference on Applied Human Factors and Ergonomics. - Cham : Springer. ; , s. 202-209
-
Conference paper (peer-reviewed)abstract
- Digitalization in railway maintenance opens new avenues for decision-making and maintenance actions. Advanced sensors and support systems help in automating railway maintenance operations, but this also brings new challenges. Dealing with huge amount of data, transparency and observability are becoming critical aspects in the digitalized word. Successively influence the human ability to gain Situation Awareness, which is considered as important human cognitive aspect for decision-making. The study elaborates the opportunities and challenges of digitalization, in a Situation Awareness perspective. Review of present studies shows that although digitalization is meant to increase: Situation Awareness is often challenged and, sometimes even hindered. Therefore, the major focus is on making recommendations using proper Situation Awareness interventions for meeting the emerging challenges of digitalization on the railway maintenance, so as to provide a better awareness about the railway systems they are dealing with. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
