Search-based system architecture development using a holistic modeling approach

This dissertation presents an innovative approach to system architecting where search algorithms are used to explore design trade space for good architecture alternatives. Such an approach is achieved by integrating certain model construction, alternative generation, simulation, and assessment processes into a coherent and automated framework. This framework is facilitated by a holistic modeling approach that combines the capabilities of Object Process Methodology (OPM), Colored Petri Net (CPN), and feature model. The resultant holistic model can not only capture the structural, behavioral, and dynamic aspects of a system, allowing simulation and strong analysis methods to be applied, it can also specify the architectural design space. Both object-oriented analysis and design (OOA/D) and domain engineering were exploited to capture design variables and their domains and define architecture generation operations. A fully realized framework (with genetic algorithms as the search algorithm) was developed. Both the proposed framework and its suggested implementation, including the proposed holistic modeling approach and architecture alternative generation operations, are generic. They are targeted at systems that can be specified using object-oriented or process-oriented paradigm. The broad applicability of the proposed approach is demonstrated on two examples. One is the configuration of reconfigurable manufacturing systems (RMSs) under multi-objective optimization and the other is the architecture design of a manned lunar landing system for the Apollo program. The test results show that the proposed approach can cover a huge number of architecture alternatives and support the assessment of several performance measures. A set of quality results was obtained after running the optimization algorithm following the proposed framework --Abstract, page iii

A Holistic Social Constructionist perspective to Enterprise Education

Purpose – Drawing on the Gestalt approach this article proposes a holistic framework for enterprise education (EE) research based on Social Constructionism, illustrating how the latter supports research into experiential learning in EE in 7 UK Higher Education (HE) pharmacy schools. Design/ Methodology/ Approach – This paper is based on a qualitative empirical study involving educators in UK Higher Education Institution (HEI) pharmacy schools in semi-structured interviews, and investigates the delivery of EE through experiential learning approaches. Social Constructionism is proposed as a suitable underlying philosophical paradigm. Findings – A Social Constructionism paradigm, which adopts relative realism ontology, transactional epistemology, and Gadamer’s Hermeneutic Phenomenology, offers a relevant, multi-perspectival philosophical foundation for EE research, supporting transactional relationships within contexts of multiple possibilities. Research limitations/implications – Social Constructionism does not necessarily support the individualistic paradigm, as advocated by Constructivists; and the values associated with the former encourage a more collaborative and cooperative approach different from the latter. Practical implications –The paper supports the understanding that applying experiential learning through inter-disciplinary and inter-professional learning is regarded as an approach beneficial for educators, institutions and learners, within the context of EE. Originality/ value – This paper offers a holistic conceptual framework of Social Constructionism that draws on the ‘Gestalt Approach’, and highlights the harmony between the ontological, epistemological and methodological underpinnings of Social Constructionism. The paper demonstrates the relevance of the proposed framework in EE research within the context of an empirical study, which is different in that it focuses on the delivery aspect of EE by considering the views of the providers (educators), an hitherto under-researched area. Paper type – Research paper Key words: Enterprise education, research philosophy, Social Constructionism, relative realism ontology, transactional epistemology, Gadamer’s Hermeneutic Phenomenology, Gestalt approach

Designing a Travel Guide to the Un-Natural World: Exploring a Design-led Methodology

The analogy of designer as tourist in the un-natural world is used as an aid for thinking my way into the nature of design research. An exploration of how the design researcher, like a tourist, travels widely through the un-natural world of thought, theory and concept. If we are to design a travel guide for the un-natural world then what would this guide book look like, why do we need it and how could it work? The paper will propose that a ‘travel guide to the un-natural world’ in the form of a design-led methodology is needed for research into sustainable development and is useful not only for the design discipline but for the research community at large. These premises have been derived from the aptitude of the design process and the creative methods it employs to deal with the complex messiness of issues such as sustainability. Such a design-led methodology would be useful for the wider research community due to the integrative abilities of the design process and the trans-disciplinary scope of the tour through the un-natural world. Design-led methodology will be explored using examples from field work in Tumut (rural New South Wales, Australia) Keywords: Design Research, Design-Led Methods, Metadesign, Sustainability.</p

Task analysis of discrete and continuous skills: a dual methodology approach to human skills capture for automation

There is a growing requirement within the field of intelligent automation for a formal methodology to capture and classify explicit and tacit skills deployed by operators during complex task performance. This paper describes the development of a dual methodology approach which recognises the inherent differences between continuous tasks and discrete tasks and which proposes separate methodologies for each. Both methodologies emphasise capturing operators’ physical, perceptual, and cognitive skills, however, they fundamentally differ in their approach. The continuous task analysis recognises the non-arbitrary nature of operation ordering and that identifying suitable cues for subtask is a vital component of the skill. Discrete task analysis is a more traditional, chronologically ordered methodology and is intended to increase the resolution of skill classification and be practical for assessing complex tasks involving multiple unique subtasks through the use of taxonomy of generic actions for physical, perceptual, and cognitive actions

Conceptual modelling and the quality of ontologies: A comparison between object-role modelling and the object paradigm

Ontologies are key enablers for sharing precise and machine-understandable semantics among different applications and parties. Yet, for ontologies to meet these expectations, their quality must be of a good standard. The quality of an ontology is strongly based on the design method employed. This paper addresses the design problems related to the modelling of ontologies, with specific concentration on the issues related to the quality of the conceptualisations produced. The paper aims to demonstrate the impact of the modelling paradigm adopted on the quality of ontological models and, consequently, the potential impact that such a decision can have in relation to the development of software applications. To this aim, an ontology that is conceptualised based on the Object Role Modelling (ORM) approach is re-engineered into a one modelled on the basis of the Object Paradigm (OP). Next, the two ontologies are analytically compared using the specified criteria. The conducted comparison highlights that using the OP for ontology conceptualisation can provide more expressive, reusable, objective and temporal ontologies than those conceptualised on the basis of the ORM approach

Contextualizing phenomenology in event management research: Deciphering the meaning of event experiences

Purpose - Although the core phenomenon of events is the experiences and the meanings attached to them, there is limited management research on the experiential, existential and ontological dimensions of events. Phenomenology provides a sound philosophical framework for studying the multifaceted dimensions of experiences and associated meanings of events. However, quite surprisingly, phenomenology has not yet been systematically applied on the event management field. This conceptual paper aims to introduce phenomenology to the study of events, demonstrate its value for the field and encourage as well as guide its application on event management research. Design/methodology/approach - A review and synthesis of the main phenomenological streams of thought was undertaken in order to develop a research paradigm for the application of phenomenology on the event management field. Findings - The paper explains why phenomenology is needed in the study of events and their management, its conceptual underpinnings and streams of thought and finally suggests a research framework for conducting phenomenological studies in event management. Research limitations/implications - The consequences of the phenomenological perspective are delineated for explaining how the study of event meanings and experiences can be undertaken from this perspective. The limitations of phenomenology are noted such as the emphasis on ‘lifeworld’ subjectivity and subsequent difficulty to claim the generalizability of research findings. Practical implications - The suggested research framework can guide future event management research on how to apply phenomenology to the study of event experiences and meanings. On this basis, practitioners can get insight regarding how to develop and design events that optimize the perceived experiences of attendees. Originality/value - While the experiential paradigm and the phenomenological turn have been spread across many disciplines emphasizing the essence of lived experiences in a variety of human interactions and exchanges, the event management field lags behind. This is unfortunate and has to be addressed as the experiences and meanings shape the essence of events. Therefore, this conceptual paper hopes to inspire, encourage and guide event management researchers to embrace and apply the phenomenological perspective on their future research endeavors, which can profitably complement and expand the predominant research paradigms in the field

Knowing differently in systemic intervention

© 2015 John Wiley & Sons, Ltd. This paper makes the case for extended ways of knowing in systemic intervention. It argues that the deployment of formal (even reflective) thinking and dialogue methods are inadequate, on their own, to the critical tasks of comprehending larger wholes and appreciating others' viewpoints. Theory and techniques need to go further and access other forms of knowing, held in experiential, practical or symbolic ways. This could offer a better basis to incorporate marginalized people and other phenomena that are affected by interventions but do not have a voice, such as ecosystems and future generations

Universal Design: Planning and Design for All

[Excerpt] This report attempts to develop and illustrate the concept of universal design. The aim of universal design is to develop theory, principles and solutions to enable everybody to use the same physical solutions to the greatest extent possible, whether it be buildings, outdoor-areas, means of communication or household goods. Universal design opposes, ideologically and politically, all unnecessary and stigmatizing specialized solutions, whether they are intended for people with disabilities or other groups of the population. Equal status, equal treatment and equal merit are key concepts. The discussion in this report covers extensive spheres such as planning, architecture and product design. One may object that we try to cover too large an area within a relatively brief report. It is therefore important to emphasise that our main intention is to include more professionals and politicians in the further discussion of universal design or design for all
