The reuse of machining knowledge to improve designer awareness through the configuration of knowledge libraries in PLM

The nature of competition induces the need to constantly improve and perform better. For global aerospace manufacturers, this is as timely an epithet as ever as market forces urge for more growth, better financial return and market position. The macroeconomic aspect is compounded by the growth of product complexity and the need for higher product quality, hence the drive to reduce waste places emphasis upon production costs and the need to improve product performance. This paper focuses upon a rapid development and deployment method that enables the capture and representation of machining knowledge so that it may be shared and reused by design engineers to accelerate the design-make process. The study and mapping of information and knowledge relationships are described and put forward as a lightweight ontology. From this, a set of knowledge document templates were created to facilitate the capture, structuring and sharing of machining knowledge within a collaborative multidisciplinary aerospace engineering environment. An experimental pilot system has been developed to test and demonstrate that knowledge document templates can accelerate the sharing of machining knowledge within an industrial product lifecycle management environment. The results are discussed to provide a case for further development and application within the product domain

Collaborative, academic-industry research approach for advancing systems engineering

In contrast to many technology-based research programmes on which industry and academia may collaborate, a programme in systems engineering – a discipline which is practitioner-focused – requires a different approach to enabling exploitation of research outputs. Those outputs tend to be process, approach and methodological in nature rather than specifically tools and technologies. The NECTISE* research programme is a multi-year, industrially-led research activity focused on developing the systems of systems (SoS) techniques required for Network Enabled Capability. The research consortium includes ten UK universities working in a multi- and cross-disciplinary manner to create more agile approaches to SoS Engineering. This paper will report the integration approaches taken in this research programme and the ways in which exploitation of the research may be achieved and demonstrated. NECTISE is composed of four topic groups investigating Systems Architectures, Through Life Systems Management, Decision Support, and Control and Monitoring, together with a number of cross-cutting themes. It has been driven by industry-derived requirements, and the industry-academic interface is enabled by the transformation of the requirements into a set of research questions. The formulation of such questions will be discussed. A major integrating activity is a set of four demonstrations that take place at regular intervals through the five-year programme. The TTCP** GUIDEx*** was found to be a helpful framework in which to integrate the various component researches for demonstration. The use of scenarios as a means of experimentation and demonstration is long-established; in NECTISE, a scenario approach is taken that embraces not only the military field of operation in which NEC is realised, but also the acquisition and support enterprise that delivers capability components to the military. In this paper, the development of the scenario, its use as a demonstration vehicle, and its role in integration across the research programme will be described, together with an assessment of the extent to which such an approach may aid exploitation of research outputs. Systems approaches have been both the focus of this research programme and the mechanisms through which it is being delivered. We shall assert that a systems approach can be a significant enabler of effective industry-academic collaborative research and we shall identify the important learning that has taken place in NECTISE in this regard. * Network Enabled Capability Through Innovative Systems Engineering ** The Technical Cooperation Program *** Guide for Understanding and Implementing Defense Experimentation (GUIDEx

Through life capability management: benefits and behaviours

Many commercial and social endeavours require a multitude of socio-technical systems to work together effectively in what has come to be known as systems of systems. The Through Life Capability Management (TLCM) construct, currently being embraced by defence departments across the globe, is one such endeavour. TLCM demands changes in the organisation and culture of the defence supply chain in ways that fly in the face of traditional commercial wisdom. This paper reports on two workshops held with TLCM stakeholders in which they identified, and then prioritised, the benefits that they sought from TLCM. From an agreed set of priority benefits, the groups identified the behaviours needed to realise them; the results point to significant challenges in terms of culture and knowledge management. Ergonomists and systems engineers will need to support development of intervention strategies to effect these required changes

Manufacturing knowledge reuse for product design

In today’s world there is ever increasing pressure to bring products to market in a quicker and more time-ly fashion that fulfill customers’ needs and are delivered on budget. One way to aid such acceleration of the design and development process is to effectively share and reuse manufacturing knowledge in an ef-fort to bring about product based interoperability. This paper reports upon the work being carried out in the SAMULET research programme that addresses such factors. It focuses upon (i) how the sources of in-formation and knowledge were recognized, (ii) the definition and categorisation of knowledge and (iii) the potential routes for the reuse of manufacturing knowledge. The research approach is currently being developed to help augment a supportive information and knowledge sharing environment and bring about a more integrated development process within a high tech aerospace company

Through-life NEC scenario development

Scenarios are an important planning tool used by individuals, businesses and governments (especially in the military domain), but many of the currently used approaches focus solely on acute probabilistic timeframes and specific metricated instances of possible future states. Using a mixed method research methodology, we develop a scenario approach in which multiple timeframes are accommodated by fitting vignettes within each other to represent different time levels. This has the advantage of presenting the end-to-end process of capability development and instantiation. We describe the methodology employed to generate such a scenario as a demonstration aid for a large, multidisciplinary research program in systems of systems engineering. The process of scenario generation was an effective integration tool within this program (that included twelve distributed research groups). The resultant scenario enabled engagement of multiple stakeholders in an integrated demonstration of systems related research outputs. We recommend a new class of scenario (a “research scenario”) for incorporation within the standard classifications of scenario types

'Good engineering governance' - an issue for ergonomists

Engineering Governance can be summarised as two questions: 'Are we doing the right things?' and 'Are we doing those things right?'. It forms a part of Corporate Governance, and in the manufacturing domain it is the key to long-term survival amid changing commercial contexts. The paper will outline some of the ergonomics issues of importance in this topic; 'ownership' of goverrnance; implications for design, production and operation; and, perhaps most important for Ergonomists, the resulting implications for the design of jobs. These implications cover organisational discipline, the inclusion of suitable, 'effort-free' metrics in engineering processes, the allocation of responsibility and authority over resources, support for individuals, the need for trust and a culture of honesty and reliability, and the necessity for organisational follow-through

An ontology for global production network design and reconfiguration

Organisations constantly seek to improve and fully exploit global production networks. This can be to provide more competitive solutions to customer requests, to exploit potential new technologies or to consider new business models based on the servitisation of products. To support such decisions requires the interchange and evaluation of information from a wide range of different and varied sources. This paper puts forward a reference ontology aimed at supporting businesses who seek to design, configure and reconfigure global production networks. The aim of this is to support interoperability between information systems within multi-domain contexts

Scenario-based design and evaluation for capability

Scenarios are frequently used within techniques for planning and designing systems. They are an especially helpful means of visualizing and understanding the incorporation of new systems within systems of systems. If used as the basis for decisions about candidate designs, then it is important that such decisions can be rationalized and quantitative assessment is particularly important. In this paper, an approach for developing complex scenarios, which incorporates the phases of systems development and deployment, is presented and a quantitative method of comparison is described. This approach is based on the development of measures of merit and measures of performance. The techniques are illustrated using cases that are relevant to Network Enabled Capability

Reference ontologies to support the development of global production network systems

In competitive and time sensitive market places, organisations are tasked with providing product lifecycle management (PLM) approaches to achieve and maintain competitive advantage, react to change and understand the balance of possible options when making decisions on complex multi-faceted problems, global production networks (GPN) is one such domain in which this applies. When designing and configuring GPN to develop, manufacture and deliver product–service provision, information requirements that affect decision making become more complex. The application of reference ontologies to a domain and its related information requirements can enhance and accelerate the development of new product-service systems with a view towards the seamless interchange of information or interoperability between systems and domains. This paper presents (i) preliminary results for the capture and modelling of end-user information, (ii) an initial higher level reference core ontology for the development of reference ontologies and (iii) the formal logical modelling of Level 1 of the FLEXINET reference ontology using a Common Logic based approach
